ABSTRACT

Abstract The evolution of beauty market and personal care is constant in Brazil as well in the rest of the world. Technological advances have brought up nanotechnology to the cosmetological field, employing active principles at atoms enveloped by vesicles, in order to take the active principle precisely to the target tissue to optimize the results achieved because of the considerable ease to cross skin barriers. Manufacturing of nanotechnology cosmetics is confronted with low absorption capacity. One of the many active principle found in cosmetic industry is caffeine, a pseudoalkaloid from the xanthine group used as a stimulant with the mechanism of the lipolytic action. This active is widely used in ​​a esthetics and cosmetics field in treatments involving dysfunctions such as localized fat and fibroedema geloid. To work out perfectly, the principle active need to interact and create a set of factors that includes lipolysis intensification. The caffeine encapsulation in gel-based nanocosmetics has the purpose of taking this active up to the adipocyte, the target cell, for mentioned dysfunctions treatment. Thus, we aim to present a review of how has been, the use of caffeine in the production of cosmetics.


Resumo A evolução do mercado de beleza e cuidados pessoais é constante no Brasil e no resto do mundo. Os avanços tecnológicos trouxeram a nanotecnologia para o campo cosmetológico, empregando princípios ativos em átomos envolvidos por vesículas, a fim de levar o princípio ativo precisamente ao tecido alvo para otimizar os resultados alcançados devido à considerável facilidade de atravessar barreiras cutâneas. A fabricação de cosméticos nanotecnológicos é confrontada com baixa capacidade de absorção. Um dos muitos princípios ativos encontrados na indústria cosmética é a cafeína, um pseudoalocalóide do grupo xantina usado como estimulante no mecanismo da ação lipolítica. Este ativo é amplamente utilizado no campo da estética e dos cosméticos em tratamentos que envolvem disfunções, como gordura localizada e fibroedema gelóide. Para funcionar perfeitamente, o princípio ativo precisa interagir e criar um conjunto de fatores que inclui a intensificação da lipólise. O encapsulamento de cafeína em nanocosméticos à base de gel tem o objetivo de levar esse ativo até o adipócito, a célula alvo, para o tratamento de disfunções mencionado. Assim, objetivamos apresentar uma revisão de como tem sido o uso de cafeína na produção de cosméticos.

ABSTRACT

Abstract As there is a great scarcity of studies on the importance of good compounding practices in the preparation of cosmetics, this study aimed to evaluate the quality control of cosmetics with active ingredient caffeine for the treatment of cellulite prepared by magistrals pharmacies. Microbiological analyzes, pH determination, color measurement, quantification of the percentage of the active ingredient caffeine and viscosity in creams and gels with 5% of the active ingredient caffeine were performed. In the microbiological analysis, the presence of molds and yeasts was verified above the permitted level according to the Brazilian pharmacopoeia. The pH decreased over time, contributing to the formulations becoming more acidic. In the color parameters, it was found that pharmacy F4 showed a brownish color, both for the gel and for the cream. The percentage of caffeine was within specifications in all formulations and the viscosity remained unchanged during the shelf life of the samples. It is important that the compounding pharmacies demand more effectively the commitment of the team, as well as the analysis of the raw material according to the microbiological control regulations to translate into the quality of the products prepared by the pharmacies and favor the consumer in the effective objective that the product you want to achieve.


Resumo Como há uma grande escassez de estudos sobre a importância de boas práticas de manipulação na elaboração de cosméticos, o presente estudo teve como objetivo avaliar o controle de qualidade de cosméticos com princípio ativo cafeína para o tratamento de celulite, elaborados por farmácias de manipulação de Campo Mourão. Foram realizadas análises microbiológicas, determinação do pH, mensuração da coloração, quantificação da porcentagem do princípio ativo cafeína e viscosidade em cremes e geís com 5% do princípio ativo cafeína. Nas análises microbiológicas foi verificada a presença de bolores e leveduras acima do pemitido segundo a farmacopéia brasileira. O pH diminuiu ao longo do tempo, contribuindo para que as formulações ficassem mais ácidas. Nos parâmetros de cor averiguou-se que a farmácia F4 apresentou uma coloração amarronzada, tanto para o gel quanto para o creme. A porcentagem de cafeína estava dentro das especificações em todas as formulações e a viscosidade se manteve inalterada durante o prazo de validade das amostras. Com o propósito de um melhor preparo magistral é importante que as farmácias de manipulação exijam de forma mais eficaz o comprometimento da equipe, bem como a análise da matéria-prima segundo as regulamentações de controle microbiológico. Além disso, a implementação de normas mais rígidas e o melhor controle da matéria-prima e das formulações finais fazem com que a qualidade dos produtos manipulados pelas farmácias magistrais seja aumentada significativamente, favorecendo o consumidor na efetiva finalidade a que o produto objetiva atingir.

ABSTRACT

Introduction: sunscreen is a cosmetic used to protect human skin from the deleterious effects of UV radiation and thus minimize the risks of developing skin cancer. Extracts produced from fruits, such as Abiu, Guava, Rambutan and Grape, have significant concentrations of chromophores and phenolic substances that have the ability to absorb UV light and neutralize free radicals. The production of cosmetics from naturally occurring substances with such activities will be of great importance for Brazilian industry and could reduce the cost of production, given the large existing biodiversity in the country. Objectives: carry out a patent search for formulations and cosmetic products that contains phenolic rich fruit extracts as photoprotective and antioxidant bioactives. Methodology: a survey of patents was carried out in the database of the National Institute of Intellectual Property (INPI) and the European Patent Office (EPO), covering a time period between 2008 and 2018, using a combination of keywords related to herbal cosmetics and sunscreens. Results: this research identifies a significant number of patents related to plant extract in association with sunscreen product, however, no patent filings were identified for cosmetic products containing extracts of the evaluated fruits, either alone or in combination, for photoprotective and antioxidant purposes. Conclusion: the Brazilian and international market for sun care products moves millions to billions of dollars annually and have a significant annual growth prospect. Considering the great biodiversity existing in the country, the production of cosmetics from naturally occurring substances with such activities will be of great importance for the Brazilian industrial sector.


Introdução: os filtros solares são cosméticos usados para proteger a pele humana dos efeitos deletérios da radiação UV e assim, minimizar os riscos de desenvolvimento de câncer de pele. Extratos produzidos a partir de frutos, como Abiu, Goiaba, Rambutan e Uva, têm concentrações significativas de cromóforos e substâncias fenólicas que têm a capacidade de absorver a radiação UV e neutralizar os radicais livres. A produção de cosméticos a partir de substâncias naturais com essas atividades será de grande importância para a indústria brasileira e poderá reduzir o custo de produção, dada a grande biodiversidade existente no país. Objetivos: realizar uma busca de registros de patentes de formulações e produtos cosméticos que contêm extratos de frutos ricos em fenólicos como bioativos fotoprotetores e antioxidantes. Metodologia: foi realizado um levantamento de patentes no banco de dados do Instituto Nacional de Propriedade Intelectual (INPI) e do Escritório Europeu de Patentes (EPO), abrangendo um período de tempo entre 2008 e 2018, utilizando uma combinação de palavras-chave relacionadas a cosméticos à base de plantas e protetores solares. Resultados: esta pesquisa identificou um número significativo de patentes relacionadas ao extrato de plantas em associação ao produto protetor solar, no entanto, não foram identificados pedidos de patente para produtos cosméticos que contenham extratos das frutas avaliadas, isoladamente ou em combinação, para fins fotoprotetores e antioxidantes. Conclusão: o mercado brasileiro e internacional de produtos de proteção solar movimenta milhões a bilhões de dólares anualmente e tem a perspectiva de crescimento anual significativa. Considerando a grande biodiversidade existente no país, a produção de cosméticos a partir de substâncias naturais com essas atividades será de grande importância para o setor industrial brasileiro.

ABSTRACT

Abstract The high consumption of antiaging cosmetics represents an outstanding opportunity for the development of new processes and attractive products in the cosmetic industry. Stability studies and sensory analyses are critical steps in the development process and production chain. Here we present a potential antiaging cosmetic product with innovative sensory characteristics. Caviar extract antioxidant properties were firstly evaluated by the DPPH method since it is an important mechanism against skin aging. Ca-alginate beads containing 2% of caviar extract and 0.2% of black pigment were prepared to obtain spheres similar to caviar. The beads were incorporated in a gel phase (hydroxyethylcellulose 2.5%) containing 3% of dimethylaminoethanol. Stability was evaluated in different storage conditions (sunlight exposure, 5 ± 2 °C, 37 ± 2 °C and r.t.) through the parameters: appearance, color and odor, pH (6-7), density (0.98-1.14 g.mL-1), centrifugation and average size. After approval by the Committee for Ethics in Research (n° 3.503.061), 30 volunteers tested the new formulation and answered a questionnaire. At 2%, caviar extract was able to scavenge 10.9% ± 0.58 of DPPH radical. Formulations showed good stability after 90 days, even considering the average size (7.47 ± 0.41 - 8.4 ± 0.65 mm2). 90% of the sensory test participants reported that they would buy the new product. Therefore, the new product developed demonstrates a promising potential as an attractive cosmetic product.

ABSTRACT

Introdução: A acne é uma doença inflamatória crônica da unidade sebácea. Embora acometa principalmente adolescentes, constata-se uma prevalência elevada em adultos, em especial nas mulheres. A acne feminina adulta tem sido associada a má qualidade de vida (QV) e é capaz de impactar tanto a autoestima como os relacionamentos pessoais e profissionais. Métodos: Trata-se de um estudo transversal de natureza quantitativa realizado através da aplicação de questionários para avaliar a QV e o perfil epidemiológico de mulheres adultas com acne facial entre 25 e 50 anos atendidas em um ambulatório clínico da Universidade do Extremo Sul Catarinense (UNESC). Resultados: Um total de 20 mulheres com acne facial participaram da pesquisa. A idade média foi de 32,45 anos, sendo a maioria branca, casada e com ensino superior incompleto. A maioria não realizou tratamento prévio, e o perfil mais encontrado foi de início da acne na adolescência e de sua persistência na idade adulta. Grande parte das mulheres utilizavam maquiagem. Além disso, foram observados baixos escores em cada um dos quatro domínios do questionário Acne-QoL, com resultados estatisticamente significativos correlacionando a idade com os domínios de autopercepção e de papel emocional. Conclusões: Os resultados destacam que a acne facial tem um impacto significativo na QV de mulheres adultas que a possuem. (AU)

ABSTRACT

Abstract Background: Cosmetics are part of the daily life of the population, and their use can lead to allergic contact dermatitis. Objectives: To assess the profile of patients diagnosed with allergic contact dermatitis to cosmetics treated at a referral center for 13 years, as well as the characteristics of the clinical picture and allergens involved. Methods: This was a retrospective study, with analysis of medical records of patients attended at this service. The individuals included had a diagnostic hypothesis of allergic contact dermatitis to cosmetics and had previously been submitted to epicutaneous tests. Results: A total of 1405 medical records were analyzed, 403 (28.7%) with suspected allergic contact dermatitis to cosmetics and 232 (16.5%) with confirmed diagnosis. Of these, 208 (89.7%) were women, and the age group most affected was 31 − 60 years. The most common locations were face in 195 cases (25.8%), cervical region in 116 (15.3%), and trunk in 96 (12.6%). The main allergens in the contact tests were toluene-sulfonamide-formaldehyde resin in 69 cases (29.7%), paraphenylenediamine in 54 (26.3%), Kathon CG® in 41 (20.7%), and fragrance-mix 1 in 29 (16.4%). In 154 (66.4%) of the 232 patients with a confirmed diagnosis of allergic contact dermatitis to cosmetics it was possible to specify the cosmetic product responsible for the lesions. Study limitations: The absence of some allergens considered important in the world as causes of allergic contact dermatitis, which are not readily accessible among us. Conclusions: The data of the analyzed population (predominance of young women), as well as the location of the lesions (face and cervical area) and the main allergens involved were consistent with those from the world literature.

ABSTRACT

Resumen Un capítulo novedoso es la atención y promoción por parte de médicos especialistas de aspectos relacionados con procedimientos estéticos, más que con la salud. La aspiración humana de la búsqueda de la belleza personal ha generado nuevos escenarios en la labor médica. El Comité de Ética y Transparencia en la Relación Médico Industria (CETREMI) de la Academia Nacional de México ha revisado esta circunstancia y emite recomendaciones tanto a los médicos como a los productores y potenciales consumidores de procedimientos estéticos.


Abstract A novel chapter in current medical settings is the promotion and attention of esthetic aspects rather than health issues by health professionals. The human aspiration related to the search for personal beauty has generated new scenarios in medical practice. The Committee on Ethics and Transparency in the Physician-Industry Relationship (CETREMI) of the National Academy of Medicine of Mexico has analyzed this phenomenon and has issued recommendations directed both to medical professionals and to producers and potential consumers of esthetic procedures.

ABSTRACT

Introdução: a rosácea é uma doença inflamatória de pele, de etiologia desconhecida. Apresenta-se na região centro-facial, com a presença de rubor, eritema, telangiectasias, pápulas e pústulas, periódicas ou persistentes. Objetivo: o objetivo deste trabalho é realizar uma revisão bibliográfica narrativa de estudos envolvendo os cuidados dermocosméticos no tratamento da rosácea. Metodologia: as buscas foram realizadas nas bases de dados: Biblioteca Virtual em Saúde (BVS), Scientific Electronic Library Online (SciELO), Literatura Latino-americana e do Caribe em Ciências da Saúde (LILACS) e PubMed. A pesquisa envolveu artigos de revistas e periódicos, monografias e dissertações em português, inglês e francês, publicadas entre os anos de 2014 a 2020. Resultados: a pele dos pacientes com rosácea é suscetível a irritabilidade, logo, é necessário uma série de cuidados diários com a pele desde a limpeza, hidratação, proteção solar, que possibilitam efeitos calmantes que melhoram a qualidade da pele. Conclusão: devido à natureza multifatorial da doença não há tratamento padronizado. Logo, os profissionais envolvidos nos cuidados desses pacientes devem esclarecer aos pacientes sobre as ações e cuidados necessários para o uso das terapêuticas, incluindo os dermocosméticos.


Introduction: rosacea, erythema, telangiectasias, papules and pustules, periodic or persistent. Objective: the objective of this work is to carry out a narrative bibliographic review of studies involving dermocosmetic care in the treatment of rosacea. Methodology: Searches were carried out in the databases: Virtual Health Library (VHL), Scientific Electronic Library Online (SciELO), Latin American and Caribbean Literature in Health Sciences (LILACS) and PubMed. The research involved magazine and periodical articles, monographs and dissertations in Portuguese, English and French, published between 2014 and 2020. Results: the skin of patients with rosacea is susceptible to irritability, therefore, a series of daily care is necessary with the skin from cleansing, hydration, sun protection, which enable calming effects that improve the quality of the skin. Conclusion: due to the multifactorial nature of the disease, there is no standardized treatment. Therefore, the professionals involved in the care of these patients must inform patients about the actions and care necessary for the use of therapies, including dermocosmetics.

ABSTRACT

Abstract Background: Kathon CG, a combination of methylchloroisothiazolinone and methylisothiazolinone, is widely used as preservative in cosmetics, as well in household cleaning products, industrial products such as paints and glues. It has emerged as an important sensitizing agent in allergic contact dermatitis. Objectives: This study evaluated the reactivity to this substance in patients subjected to patch tests at the Dermatology Institute in Bauru, São Paulo from 2015 to 2017 and its correlation with other preservatives, the professional activity and location of the lesions. Methods: The patients were submitted to standard series of epicutaneous tests, standardized by the Brazilian Group Studies on Contact Dermatitis. Results: Out the 267 patients tested, 192 presented positivity to at least one substance and 29 of the patients (15.10%) presented reaction to Kathon CG, with predominance of the female gender (n = 27); main professional activity associated with Kathon CG sensibilization was cleaning (17.24%), followed by aesthetic areas (13.79%) and health care (10.34%). The most prevalent sensitizations among the substances tested were nickel sulphate (56.3%), followed by cobalt chloride (23.4%), neomycin (18.2%), potassium dichromate (17.7%), thimerosal (14.5%), formaldehyde (13.2%), paraphenylenediamine (9.3%), and fragrance mix (8.3%). Study limitations: We do not have data from patients that were submitted to patch test a decade ago in order to confront to current data and establish whether or no sensitization to Kathon CG has increased. Conclusion: High positivity to Kathon CG corroborates the recent findings in the literature, suggesting more attention to concentration of this substance, used in cosmetics and products for domestic use.

ABSTRACT

Resumen Introducción: Las infecciones asociadas a la atención de salud son un problema frecuente en el ambiente hospitalario. La higiene de manos es la medida más efectiva para su prevención. El uso de ciertos accesorios en las manos podría disminuir su efectividad y favorecer la transmisión horizontal de agentes infecciosos. Objetivo: Revisar los estudios publicados que evalúan el impacto del uso de anillos y uñas esmaltadas en la calidad de la higiene de manos en trabajadores de la salud. Métodos: Búsqueda no sistemática en base de datos PUBMED/MEDLINE (1978-2018) de estudios en los cuales se mide la calidad de la higiene de manos o lavado quirúrgico, mediante cultivos cuantitativos o tinciones fluorescentes. Resultados: Uso de anillos: Trece de 51 artículos cumplían los criterios de inclusión. Siete fueron realizados en unidades clínicas, y en todos ellos éste se asoció a menor calidad de la higiene de manos (la mayoría de baja calidad). Contrariamente, en tres de cuatro estudios primarios realizados en pabellón (de baja calidad), su uso no impactó en la calidad del lavado quirúrgico. Igualmente, dos revisiones sistemáticas obtuvieron similares conclusiones. Uñas esmaltadas: siete de 54 artículos fueron incluidos. En cuatro hubo resultados discordantes (la mayoría de baja calidad). En un estudio controlado se observó reducción en la calidad del lavado quirúrgico sólo cuando el esmalte estaba dañado. El esmalte gel se asoció a menor calidad de la higiene de manos en dos estudios experimentales. Conclusiones: No existe evidencia de calidad suficiente para asociar el uso de estos accesorios con reducción en la calidad de la higiene de manos. Tampoco queda demostrada su inocuidad. En base a la evidencia disponible (la mayoría de baja calidad), se observó un impacto negativo del uso de anillos en unidades clínicas y también de uñas con esmalte dañado en pabellones quirúrgicos. Se requieren estudios de mejor calidad para abordar estos relevantes tópicos.


Abstract Background: Health-care-associated infections are a frequent problem in hospital environments. Hand hygiene is the most effective measure to prevent outbreaks. The use of certain accessories could decrease its effectiveness, facilitating horizontal transmission of pathogens. Objective: Analyze the evidence that assess the impact of the use of rings and nail polish on hand hygiene quality in healthcare workers. Methods: Non-systematic search in PUBMED/MEDLINE database (1978-2018) of studies in which the quality of hand hygiene or surgical washing is measured, using quantitative cultures or fluorescent stains. Results: Wearing rings: 13 studies met the inclusion criteria. Seven were carried out in general wards. In all of them the use of rings was associated with lower quality of hand hygiene (the majority of low quality). Contrarily, in 3 of 4 primary studies carried out in the operating rooms (of low quality), their use did not affect the quality of surgical washing. Similarly, two systematic reviews obtained similar conclusions. Nail polish: 7 of 54 studies met the inclusion criteria. In four of them there were discordant results (the majority of low quality). One RCT showed a reduction in the quality of surgical washing only when the nail polish was damaged. Gel nail polish was associated with lower quality in two experimental studies. Conclusions: There is insufficient evidence to associate the use of these accessories with the reduction in the quality of hand hygiene. Its safety was not proven neither. Based on the available evidence (the majority of low quality), a negative impact of the use of rings in clinical units and also of damaged nail polish in operating rooms was observed. Better quality studies are required to address these relevant issues.

ABSTRACT

The skin is the largest and most exposed organ of the human body, therefore subject to diseases and alteration of its appearance. Among these alterations, the cutaneous hyperchromia may be cited. Currently, the market offers numerous products with depigmenting action to the treatment of such disorders. The aim of this work was to analyze depigmenting products commercialized in establishments in the city of Bento Gonçalves (RS, Brazil) and websites of cosmetic companies. It was found 45 products with depigmenting action and, from these, 59 different active agents were identified. The main active compounds found were kojic acid, arbutin, ascorbic acid, hydroquinone and glycolic acid. Another observed data was that in 78% of the studied products the active substances were being used in combination. The most used vehicles were also studied as a reference to the use of sunscreen in the treatment of cutaneous hyperchromia. The present work had identified in the market a variety of products with depigmentation action and, because of this, it aims to serve as a reference to the healthcare professionals, especially at the prescribing moment, looking for the best results, with regards to treatment efficiency and safety.(AU)

ABSTRACT

Formaldehyde is an active compound, irregularly used in hair products, that has the property of straighten and waterproofing the wires. However, it is highly toxic and can stimulate dermatological hypersensitivity and cancer. In this context it is of fundamental importance the inspection of these products that can be used in safe conditions for the consumer, without formaldehyde in concentrations higher than the allowed. Thus, the aim of this research was the qualitative and quantitative identification formaldehyde in samples of hair straighteners that was obtained by donation in the beauty salons of Araraquara-SP. In addition, the analysis of the packaging labels of the products tested were conducted, following the requirements of the national legislation - RDC 07/2015 which defines the mandatory labeling standards for cosmetic products. A qualitative analysis for formaldehyde identification is based on the formation of a purple colored complex. The quantitative analysis was performed by spectrophotometry. The qualitative and quantitative formaldehyde analysis methods were applied to 13 bottles of hair straighteners. When submitted to qualitative analysis, all samples showed formaldehyde presence. The quantitative analysis demonstrated that the samples identified as B, C, D, E, G, H, I, J and M presented formaldehyde concentration of 3.5 to 14.5%, which is above of the limit recommended by the National Health Surveillance Agency (ANVISA), of 0.2%. In the label analysis, in all samples were found irregularities.(AU)

ABSTRACT

Resumo Por meio de um exercício de walking ethnography, pretendemos apresentar uma etnografia da oferta cosmética destinada à despigmentação da pele no coração de Lisboa, focando num fragmento da cidade que junta diferentes propostas e produtos estéticos: spas chineses, salões de beleza e cabeleireiros africanos, lojas do comércio dito "étnico" ligado a imigrantes e portugueses descendentes de populações asiáticas ou africanas. Definimos esse passeio como "caminho do branqueamento" - parafraseando ironicamente o título de um dos mais famosos livros de Michael Jackson, Paths towards a clearing (1989). Considerando o corpo como um projeto em construção, pretendemos mostrar que os imaginários e os desejos ligados ao consumo desses tratamentos, assim como os padrões de beleza veiculados pelo marketing dos produtos de clareamento da pele, refletem e reproduzem variáveis sociais de género, classe e raça. Queremos também evidenciar como a maior parte dos produtos branqueadores, vendidos no centro da cidade, são proibidos pela legislação europeia de regulamentação de cosméticos, devido às altas concentrações de substâncias tóxicas. Essas substâncias, que circulam livremente nas redes do comercio informal, podem ser muito prejudiciais para a saúde dos consumidores, comportando severos riscos dermatológicos.


Abstract Through a walking ethnography exercise, we intend to present an ethnography of the cosmetic offer aimed at depigmenting the skin in the heart of Lisbon, focusing on a fragment of the city that brings together different proposals and aesthetic products: Chinese spas, beauty salons and African hairdressers, shops of the so-called "ethnic" trade linked to immigrants and Portuguese descendants of Asian or African populations. We defined this tour as a "whitening path" - ironically paraphrasing the title of one of Michael Jackson's most famous books, Paths towards a clearing (1989). Considering the body as a project under construction, we intend to show that the imaginary and desires related to the consumption of these treatments, as well as the beauty standards conveyed by the marketing of skin whitening products, reflect and reproduce social variables of gender, class and race. We also want to highlight how most whitening products, sold in the city center, are prohibited by European cosmetics regulation legislation due to the high concentrations of toxic substances. These substances - which circulate freely in the networks of informal commerce - can be very harmful to the consumers' health, carrying severe dermatological risks.

ABSTRACT

Abstract The pulp oil of Caryocar brasiliense Camb., better known as pequi, is used in the typical cuisine of the Brazilian Cerrado region. It is also used in folk medicine to combat several types of disease of the respiratory system and skin. However, since its exploration is purely extractive, the exhaustion of this plant is already foreseen. Thus, in order to establish the sustainable use of pequi and contribute to its maintenance, this study aimed to develop a phytocosmetic with antioxidant and photoprotective properties using the oil of this fruit. Initially, the cytotoxicity of the oil was evaluated in order to establish the safety of its use and its fatty acid composition. Then, from the cream enriched with the oil, it was evaluated the antioxidant and photoprotector potentials, quantified the total phenolic content and examined the quality of the formulation. Pequi oil showed high percentages of palmitic (52.11%) and oleic (44.57%) fatty acids and absence of cytotoxicity. The analysis of the cream revealed 168.8 mg of total phenols in gallic acid equivalent per 100 g of oil. The evaluation of antioxidant activity showed an EC50 of 2.921 mg/mL and a capacity of inhibiting the lipoperoxidation process higher than 100%. The obtained sun protection factor was 11.40 at the concentration of 6.25 mg/mL. The quality tests revealed small disturbances in the cream stability that can be solved by further research and improvement of the formulation. The pequi oil can be converted into a phytocosmetic of great commercial value.

ABSTRACT

Recentemente, produtos farmacêuticos e cosméticos com concentrações mínimas de parabenos e outros conservantes ganharam e apelo comercial e de segurança, devido à controvérsia sobre a segurança dos conservantes. No entanto, o uso de conservantes é essencial para garantir a conservação microbiana de produtos cosméticos e farmacêuticos durante o seu uso. Neste trabalho, desenvolveu-se um método quimiométrico de espectroscopia no infravermelho com Fourier transform near-infrared (FTIR) para prever a eficácia de sistemas conservantes em produtos farmacêuticos e cosméticos tópicos usando os conceitos de Quality by design (QbD) e Process Analytical Technology (PAT). A abordagem de QbD foi usada para determinar a eficácia antimicrobiana frente aos microrganismos: Candida albicans (ATCC 10231), Escherichia coli (ATCC 8739) e Staphylococcus aureus (ATCC 6538), em funções das concentrações de parabenos, e determinar a região de Design Space, empregando o delineamento de compóstio central (CCD) Todas as 15 formulações preparadas foram analisadas utilizando um espectrofotômetro (FTIR) equipado com aparato de Attenuated Total Reflectance (ATR). Os modelos de regressão por Partial Least Squares (PLS) para predição dos "slopes" das curvas de morte microbiana em função dos espectros ATR/FTIR foram bem ajustados, com R2 e R2-predição de 0,9937 e 0,8921, 0,9947 e 0,8783, e 0,9957 e 0,9222 para Candida albicans (ATCC 10231), Escherichia coli (ATCC 8739) e Staphylococcus aureus (ATCC 6538), respectivamente. O método FTIR proposto aplicado em uma abordagem de PAT foi capaz de prever a eficácia do sistema conservante em tempo reduzido. Este método de predição de silício permitirá um controle lote-a-lote da eficácia do sistema conservante de produtos farmacêuticos e cosméticos


Recently, pharmaceuticals and cosmetics with minimal concentrations of parabens and other preservatives have gained and commercial and safety appeal due to controversy over the safety of preservatives. However, the use of preservatives is essential to ensure the microbial conservation of cosmetic and pharmaceutical products during use. In this work, a chemometric method of infrared spectroscopy with Fourier transform (FTIR) was developed to predict the effectiveness of preservative systems in pharmaceutical products and topical cosmetics using the concepts of Quality by design (QbD) and Process Analytical Technology (PAT). The QbD approach was used to determine antimicrobial efficacy against candida albicans (ATCC 10231), Escherichia coli (ATCC 8739) and Staphylococcus aureus (ATCC) microorganisms 6538), in functions of paraben concentrations, and determine the Design Space region, employing the design of central composite (CCD). All 15 prepared formulations were analyzed using a spectrophotometer (FTIR) equipped with Attenuated Total Reflectance (ATR). The Partial Least Squares (PLS) regression models for the prediction of the slopes of microbial death curves as a function of ATR /FTIR spectra were well adjusted, with R2 and R2-prediction 0.9937 and 0.8921, 0.9947 and 0.8783, and 0.9957 and 0.9222 for Candida albicans (ATCC 10231), Escherichia coli (ATCC 8739) and Staphylococcus aureus (ATCC 6538)respectively. The proposed FTIR method applied in a PAT approach was able to predict the effectiveness of the preservative system in reduced time. This method in silico prediction will allow a batch-to-lot control of the effectiveness of the preservative system of pharmaceuticals and cosmetics

ABSTRACT

Os aminoácidos tipo micosporinas (MAAs) são compostos, produzidos por algumas espécies de cianobactérias e outros microorganismos, principalmente quando são expostos a radiação ultravioleta (UVR). Estes compostos, que vêm demonstrando funções fotoprotetoras e antioxidantes, têm sido pesquisados para aplicação em protetores solares e em produtos antienvelhecimento. O presente estudo focou na caracterização de cianobactérias e outros organismos quanto à produção de MAAs com potencial aplicação em cosméticos. Neste estudo foram desenvolvidos diversos métodos para identificação (via HPLC-DAD-MS/HRMS), purificação (via HPLC-DAD) e quantificação de MAAs (via LC-MS/MS). Pelo método de identificação de MAAs verificou-se que, das 75 cianobactérias estudadas, 27 cepas (38%) sintetizam MAAs. A cepa Oscilatoria sp. CMMA 1600 produziu a maior diversidade de MAAs. 10 MAAs diferentes foram identificados incluindo um MAA de massa molecular 316 Da. Através de dados espectroscópicos obtidos via HPLC-DAD-HRMS e RMN 1D e 2D confirmou-se que se tratava da micosporina-glicina-alanina. A biossíntese natural deste composto por cianobactérias foi relatada pela primeira vez neste estudo. Quanto à quantificação de MAAs, o protocolo de extração otimizado possibilitou uma excelente recuperação dos compostos de interesse, além de ser bastante simples e não utilizar solventes poluentes. As análises via LC-MS/MS foram realizadas através de experimentos de MRM em modo positivo usando uma coluna de fase reversa. O método validado permitiu determinar e quantificar com precisão os MAAs porphyra-334, shinorina e micosporina-glicina-alanina em corridas de apenas 6 minutos, com limites de deteção inferiores a 0,005 µg.mg -1. Aplicando o método de LC-MS/MS realizaram experimentos de indução de MAAs através de exposição à UVR tendo-se observado um aumento da concentração de MAAs nas cepas que já sintetizam estes compostos e, outras cepas começaram a produzir pelo menos um MAA. As cepas de S. torques-reginae (ITEP-024 e ITEP-026) produziram a maior concentração de MAAs. A cepa ITEP-024 foi ainda exposta a diferentes radiações tendo-se observado que a UVB é que mais influencia a produção de MAAs. Neste estudo foi demonstrado o potencial das cianobactérias como produtores de MAAs que podem ser utilizados como fotoprotores em protetores solares


Mycosporines and mycosporine-like amino acids (MAAs) are UV-absorbing compounds produced by cyanobacteria and other organisms, especially upon exposer to solar ultraviolet radiation (UVR). These compounds are photoprotective and some have additional antioxidant functíons useful to the natural cosmetics market. This study aims to identify MAAs-producing cyanobacteria with potential applicatíons in cosmetics. A HPLC-DAD-MS/HRMS method for the identification of MAAs was developed. Out of the 75 cyanobacteria studied, 27 strains (38%) synthesized MAAs. Oscilatoria sp. CMMA 1600, from homocyte type, produced the greatest diversity of MAAs. 10 different MAAs were identified including a MAA with molecular weight of 316 Da. The chemical structure of mycosporine-glycine-alanine was confirmed by 1D/2D NMR and HRMS analyses. This compound has never been reported from a natural source. In this study, a validated LC-MS/MS quantification method for MAAs is also presented. An easy-to-handle and rapid extraction procedure was developed which uses only water and volatile additives as the extractor solvents. The LC-MS/MS method was performed using multiple reaction monitoring in positive mode with a reverse-phase column. The method enabled the accurate determination and quantification of the MAAs porphyra-334, shinorine and mycosporine-glycine-alanine in a 6 minutes running time, with limits of detection < 0.005 µg.mg-1. MAAs induction experiments were performed through UVR exposure. MAAs are constitutively produced by some cyanobacteria and production was further enhanced following UVirradiance. Other strains start to produce at least one MAA after UV-irradiance. Sphaerospermopsis torques-reginae strain (ITEP-024 and ITEP-026) produced the highest concentration of these photoprotective compounds. S. torques-reginae ITEP 024 strain was further exposed to different radiation compositíons. MAAs were significantly influenced by UVB. In this study, the potential of cyanobacteria as MAA producers, that can be used as photoprotectors in sunscreens, has been demonstrated

ABSTRACT

INTRODUCCIÓN: Los productos de aseo y cosméticos son necesarios en el diario vivir y ampliamente utilizados por la población. Sin embargo, su uso puede no estar exento de riesgos, especialmente cuando no se utilizan o almacenan según lo recomendado. Es importante caracterizar las exposiciones, ya que eso es útil para implementar estrategias para reducir la morbilidad, mortalidad y costos asociados, especialmente en la población infantil. OBJETIVO: Caracterizar los reportes asociados a exposiciones a productos de aseo y productos cosméticos en pacientes menores de 12 años reportados al Centro de Información Toxicológica de la Universidad Católica de Chile (CITUC). PACIENTES Y MÉTODO: Estudio descriptivo transversal de llamados telefónicos reportados a CITUC durante el año 2016. Se analizaron las variables: edad, sexo, agente, interlocutor, localización del interlocutor e inciden te, circunstancia de exposición, vía(s) de exposición, sintomatología, y severidad, mediante fichas de registro manual y desde el software de registro electrónico denominado "INTOX Data Manage ment System" de la OMS. RESULTADOS: Cumplieron criterios de inclusión 3.415 casos. Los menores de 5 años representaron el 91% de las exposiciones y el 58,5% correspondió al sexo masculino. Un 99,4% correspondió a exposiciones accidentales y el 98,6% ocurrieron en el hogar. El 68,3% no presentó síntomas, tras la exposición. Las llamadas fueron realizadas por familiares (57%) y personal de salud (42%). Los 4 agentes con mayor incidencia fueron cloro doméstico (27,6%), limpiadores y lustres de pisos (13,1%), lavalozas (7,9%) y perfumes/colonias (5,8%). La principal vía de exposición fue digestiva (89,4%). CONCLUSIONES: Los productos de aseo y cosméticos son causas comunes de exposiciones especialmente en menores de 5 años. Si bien son productos de baja mortalidad y morbilidad, es importante educar a la población para prevenir posibles intoxicaciones en la población infantil.


INTRODUCTION: Household cleaning products and cosmetics are necessary for daily life and widely used by the population. However, their use may not be risk-free, especially when they are not used or stored as recommended. It is important to characterize exposures, as this is useful for developing stra tegies to reduce morbidity, mortality, and health costs associated, especially in the child population. OBJECTIVE: To describe reports associated with household cleaning products and cosmetics exposure in patients under the age of 12, reported to the Poison Information Center of the Catholic University of Chile (CITUC). PATIENTS AND METHOD: Descriptive cross-sectional study of phone calls to CITUC during 2016. The analyzed variables were age, sex, product, caller, caller and incident location, ex posure circumstances, exposure route(s), symptoms, and severity from manual records and from the WHO's electronic record software 'INTOX Data Management System'. RESULTS: 3,415 cases met the inclusion criteria. Children under the age of five represented 91% of the exposures, and 58.5% were male. 99.4% were accidental exposures, and 98.6% occurred at home. Family members (57%) and health personnel (42%) made the calls. 68.3% of the patients had no symptoms after exposure. The four products with the highest incidence were household bleach (27.6%), floor cleaners and polishers (13.1%), dish soap (7.9%), and perfume/cologne (5.8%). The main exposure route was by ingestion (89.4%). CONCLUSIONS: Household cleaning products and cosmetics are common causes of exposures especially in children under the age of five. Although these products have a low morbidity and mortality rate, it is important to educate the population to prevent possible poisonings in the child population.

ABSTRACT

In this study, leftover roots of Sansing green onions grown without toxic chemicals in Sansing Township, Ilan County, Taiwan were used as a raw material of skincare products. The raw material was extracted from the green onion roots by ultrasound in a low-temperature, safe and pollution-free environment. We hope to develop cleansers and other facial care products made of this natural, environmentally friendly, safe and affordable raw material so that people with sensitive skin can also use these products. We also hope that this study can contribute to circular economy and achieve the goal of green innovation by recycling the leftover roots. In terms of anti-oxidation, the DPPH free radical scavenging ability of 2.5 mg/mL green onion root extract was equivalent to 98% of that of 1 mg/mL BHT; the Fe2+ chelating ability was equivalent to 87.0% of that of 0.02 mg/mL EDTA; the superoxide anions scavenging ability of 2.5 mg/mL green onion root extract was equivalent to 84.2% of that of 1 mg/mL BHT and 80.4% of that of 0.05 mg/mL vitamin C. With respect to melanin synthesis inhibition, the green onion root extract's ability to inhibit dopachrome, the intermediate product of melanin, was positively correlated to its concentration, i.e., the higher the concentration of the green onion root extract, the better the inhibition ability. The IC50 of green onion root extract was 1.83 mg/mL, while, for comparison, the IC50 of vitamin C was 0.62 mg/mL. Furthermore, according to the cell survival assay, no obvious cytotoxic effect was found with the increase in the concentration of the green onion root extract. The whitening effect improved after 30 days of test. The improvement rate was 5.6% for 2.5 mg/mL green onion root extract, 3.1% for 1.25 mg/mL extract, and 1.7% for 0.625 mg/mL extract. The moisture retention also improved after 30 days of test. The moisture retention improvement rate was 22.7% for 2.5 mg/mL green onion root extract, 21.6% for 1.25 mg/mL extract, and 15.4% for 0.625 mg/mL extract. Based on the experiments, the green onion root extract obtained from ultrasound not only did not cause skin allergy and irritation but also showed anti-aging, melanin synthesis inhibition, whitening and moisture retention effects. The results showed that the green onion root extract can improve the moisture retention and whitening effect of the mask.


Neste estudo, restos de raízes de cebolinhas Sansing, cultivadas sem produtos químicos tóxicos no município de Sansing, Condado de Ilan, Taiwan, foram utilizadas como matéria-prima de produtos para a pele. A matéria-prima foi extraída das raízes de cebolinha por ultrassom em um ambiente de baixa temperatura, seguro e livre de poluição. Esperamos desenvolver produtos de limpeza e outros produtos para cuidados faciais produzidos com essa matéria-prima natural, ecologicamente correta, segura e acessível, para Improvement rate (%) Moisture retention Whitening effect 7.65 1.29 que pessoas com pele sensível também possam usar esses produtos. Também esperamos que este estudo possa contribuir para a economia circular e alcançar o objetivo da inovação ecológica, reciclando restos das raízes. Em termos de anti-oxidação, a capacidade de sequestro do radical livre DPPH de 2,5 mg/mL de extrato de raiz de cebolinha foi equivalente a 98% de 1 mg/mL de BHT; a capacidade quelante do Fe2+ foi equivalente a87,0% de 0,02 mg/mL de EDTA; a capacidade de sequestro de ânions superóxidos de 2,5 mg/mL de extrato de raiz de cebolinha foi equivalente a 84,2% de 1 mg/mL BHT e 80,4% de 0,05 mg/mL de vitamina C. No que diz respeito à inibição da síntese de melanina, a capacidade do extrato de raiz de cebolinha de inibir o dopacrômio, o metabolito intermediário de melanina, foi positivamente correlacionada com a sua concentração, ou seja, quanto maior a concentração do extrato de raiz de cebolinha, maior a capacidade de inibição. O IC50 de extrato de raiz de cebolinha foi de 1,83 mg/mL, enquanto que, por comparação, o IC50 de vitamina C foi de 0,62mg/mL. Além disso, de acordo com o ensaio de sobrevivência celular, nenhum efeito citotóxico foi observado com o aumento da concentração do extrato de raiz de cebolinha. O efeito de branqueamento melhora após 30 dias de ensaio. A melhoria foi de 5,6% para 2,5 mg/mL de extrato de raiz de cebolinha, 3,1% para 1,25 mg/mL de extrato e 1,7% para 0,625 mg/mL de extrato. A retenção de umidade também melhorou depois de 30 dias de teste. A taxa de melhoria de retenção de umidade foi de 22,7% para 2,5 mg/mL de extrato de raiz de cebolinha, 21,6% para 1,25 mg/mL de extrato, e 15,4% para 0,625 mg/mL de extrato.Com base nas experiências efetuadas, o extrato de raiz de cebolinha obtida por ultrassom não só não causa alergia nem irritação da pele, mas também demonstrou atividade anti-envelhecimento, inibição da síntese de melanina, capacidade de branqueamento e retenção de umidade. Os resultados mostraram que o extrato de raiz de cebolinha pode melhorar a retenção de umidade e efeito de branqueamento da máscara.
