Frequency of perfume in 398 children's cosmetics

Abstract Objective: Perfume (Parfum) or fragrance is a natural or synthetic cosmetic ingredient added to emit a pleasant aroma or to improve the odor of a cosmetic formula. It is a mixture of substances, not revealed by the manufacturer, which may contain ingredients with allergenic potential, endocrine disruptors, and other possible harmful effects on human health. This study aims to analyze children's cosmetics labels to assess the presence of Perfume. Methods: The researchers randomly visited points of sale in Curitiba, the capital of a southern Brazilian state; in order to catalog the largest possible number of children's cosmetics items. Results: 398 children's cosmetics were analyzed and found Parfum on 295 (74.1 %) of the labels, including 90.4 and 79,1 % of the shampoos and wet wipes, respectively. Conclusion: Exposure of children's skin to fragrances can lead to local side effects such as allergies, but also to systemic effects, and the lack of knowledge of the general population and health professionals about its possible deleterious effects emphasizes the importance of changes in the regulation of cosmetics aiming to reduce the use of this ingredient.

Positive results of patch tests with fragrance markers: analysis of a 15-year period at a Brazilian dermatology center

Abstract: Fragrances may cause allergic contact dermatitis. Data on patients who were patch tested, between 2000 and 2015, with fragrance allergens included in the Brazilian baseline series (balsam of Peru, colophony and fragrance mix I), were collected and analyzed. Of these patients, 258 (13.8%) were positive for fragrance markers, 9.8% being positive for fragrance mix I. Among these 258 there was a predominance of women in their 40s, with hand eczema. The frequency of sensitization to fragrances, as well as the epidemiological profile, was supported by the literature. Fragrance mix I was the main marker. It is important to expand the fragrance markers used in the Brazilian baseline series of patch tests.

Olores agradables y desagradables en las exposiciones científicas orales / Pleasant and unpleasant smells in the oral scientific expositions

La imagen personal influye en la opinión de la audiencia sobre un discurso y quien lo pronuncia; por tanto, si la persona aspira a que ese aspecto de la comunicación no verbal se convierta en una herramienta que impulse su éxito ante el público, debe ser siempre un arma a su favor en cualquier momento u oportunidad. En el artículo, además de un poco de historia sobre el asunto, se ofrecen determinados consejos y orientaciones -- quizás algunos desatendidos y otros obviados involuntariamente -- acerca de los perfumes y ciertos olores, pero sin duda muy trascendentes en las exposiciones científicas orales.

The personal image influences on the opinion of the audience about a speech and about who pronounces it; therefore, if the person pretends that this aspect of the non verbal communication becomes in a tool which impels his success in front of the public, it should always be a weapon to his favor at any moment or opportunity. In the article, besides some history on the matter, certain advices and orientations are offered -- maybe some disregarded and others involuntarily obviated -- about the perfumes and certain smells, but undoubtedly very transcendent in the oral scientific expositions.

Estudo da correlação instrumental e sensorial de uma composição aromática aplicada na pele em função do ciclo menstrual / Study of instrumental and sensory correlation of a aromatic composition on the skin in function of mentrual cycle

A área de perfumaria no mundo vem se desenvolvendo a cada dia buscando maior conhecimento das matérias-primas aromáticas, desde suas reações, estabilidade até suas interações com o substrato onde é aplicado, sempre em busca do conhecimento de todas as variáveis que possam influenciar a relação perfume-substrato e a aceitação dos consumidores, medida por meio da avaliação sensorial. Apesar de muitos estudos sobre a relação perfume-pele, poucos envolveram a relação com ciclo menstrual. Neste estudo o objetivo foi correlacionar às análises sensorial e instrumental (medidas biomecânicas e cromatográficas), estudar as matérias-primas aromáticas em função do ciclo menstrual. O estudo envolveu indivíduos com idade entre 18-40 anos: 29 mulheres e 3 homens, estes usados como grupo controle. Cada voluntária teve 40 µl da composição aromática Ciclo 1910 aplicado no antebraço, onde foram feitas as medidas biomecânicas (corneometria, sebumetria e TEWL) nos tempos inicial e 6h. Nos tempos inicial, 1.5h, 3h, 4,5h e 6h se auto-avaliaram sensorialmente a intensidade de perfume por meio de escala sensorial de magnitude rotulada (LMS) e foram coletados os compostos aromáticos liberados pela técnica de headspace e analisados por espectrometria com cromatografia a gás e detetor de massa (CGMS). Realizou-se também medidas biomecânicas de corneometria, sebumetria e TEWL interescapulares em 5 voluntárias nos tempos inicial e 6h para comparação. Os resultados obtidos foram que as fases do ciclo não interferiram nas variáveis biomecânicas (p>0,05) quando analisadas isoladamente. Para as medidas realizadas no antebraço, os índices de Corneometria (p<0,001) e TEWL (p: 0,011) na região tratada apresentou média maior que a do controle. A média dos índices de Corneometria e Sebumetria da região do antebraço tratada foi menor (p<0,001) que da região interescapular. Na análise cromatográfica não houve um padrão de resposta em diferentes fases do ciclo. As correlações entre a avaliação sensorial e instrumental (cromatografia e propriedades biomecânicas) não observaram nenhum nível de correlação (p>0,05). A Cromatografia (dados cromatográficos) foi maior na fase Folicular que nas fases Menstrual e Ovulatória (p=0,003), ao considerar como variável resposta em função do ciclo menstrual e da avaliação sensorial. Houve uma forte correlação positiva entre a análise sensorial e a avaliação na pele do homem (p<0,001). No entanto, o fator intrínseco do indivíduo Mulher influenciou na resposta, ocasionando grande variabilidade, porém percebeu-se claramente que os hormônios sexuais interferiram na resposta sensorial, cromatográfica e biomecânica da pele

The perfumery in the world has been developed everyday bringing more knowledge about aromatic raw-materials, as from chemistry reactions, stability until their interactions with substrate where is applied, always looking for variables could influence in the relation perfume-substrate and consumer acceptability, measured by sensory evaluation. Despite a lot of studies were done on this subject, few involved effects as function of menstrual cycle. The aim of this study was to correlate sensory and instrumental analysis (biomechanical and chromatographic measurements), to study the olfactory profile of raw materials in function of menstrual cycle. The study involved people with 18-40 years old: 29 volunteers, three men, who were used as control group. Each volunteer had 40 µl of perfume applied on forearm, where were done Biomechanical measurements (Corneometer, Sebumeter and TEWL) at initial and 6h, At time initial, 1.5h, 3h, 4.5h and 6h; they did self-sensory assessment in perfume intensity in own forearm using labeled magnitude scale (LMS) and also where aromatic compounds released were collected by headspace technique spectrometry and gas chromatography with mass detector (CGMS). In addition, it was done biomechanical measurements (Corneometer, Sebumeter and TEWL) on interscapular region at initial and 6h for comparing. Resulting that the phases of the cycle did not affect the biomechanical variables (p > 0.05) when analyzed individually. For measurements in the forearm, Corneometry index (p < 0.001) and TEWL (p=0.011) in the treated area were higher than the control. The average of the Sebumetry, Corneometry indexes of the forearm treated was lower (p <0.001) than the interscapular region. In the analysis of chromatographic, there was a standard response at different stages of the menstrual cycle, however the analysis by individual had no a pattern response to the release of aromatic compounds. The correlations between sensory and instrumental (chromatography and biomechanical properties) did not observe any correlation (p> 0.05). But when considering chromatography as the response variable as a function of the menstrual cycle and the sensory evaluation, the follicular phase was higher than the Menstrual and Ovulatory phase (p=0.003). There was a strong positive correlation between sensory analysis and evaluation on men skin (p<0.001). However, the intrinsic factor of the individual woman influenced the response, leading to large response variability; however, see clearly that sex hormones interfere in the sensory response, chromatographic and biomechanics of the skin
