ABSTRACT
La industria cosmética brinda importancia al logro de un cosmético más completo, un cosmecéutico, que represente seguridad en el mantenimiento de la salud y la belleza. En este trabajo se diseñaron y desarrollaron 2 mascarillas faciales para el acné con quitina al 2 por ciento como sustancia activa. Este polímero de origen marino posee propiedades hidratantes, filmógenas, ha sido demostrada su acción cicatrizante y antimicrobiana. Se realizaron 2 diseños de experimentos con mezcla D-optimal, y se estudió la incidencia de 3 componentes en ambas mascarillas: polyquaternium-7 (salcare SC91®) en una de las variantes a ensayar y carboximetil celulosa sódica (CMC) en la otra, propilenglicol y agua en ambos casos. Se analizaron en el tiempo el pH y la extensibilidad; resultó óptima la variante 4 del diseño (salcare SC91 2 por ciento , propilenglicol 2 por ciento y agua al 91,6 por ciento ) en el caso de la formulación con salcare y la variante 5 (CMC 2 por ciento , propilenglicol 4 por ciento y agua 89,6 por ciento ) en la formulación con CMC
The cosmetics industry attaches importance to the achievement of a more complete cosmetic, a cosmoceutic representing safety in health and beauty maintenance. In present paper were designed and developed two face packs for acne using 2 chitin as active substance. This polymer of marine origin has phylmogen and hydration properties and a demonstrated healing and antimicrobial action. Two experimental designs were carried out with a D-optimal mixture and also the study of incidence of three components of both face packs, polyquaaterium-7 (salcare SC91®) in one of the variants be assayed and sodium cellulose carboxymethyl (SCC) in the other one, 2 percent propylene glycol and 91,6 percent water) in the case of salcare formula and the 5 variant (2 percent SCC, 4 percent propylene glycol and 89,6 percent water) in SCC formula

AIM protective effects of the Marine Face Pack (MFP) on hairless mice damaged by ultraviolet B(UVB) and it's relation to antioxidants were studied. MATHODS oxidative damage models of hairless mice irradiated by ultraviolet B (radiating intension; UVB 5. 15 ? 10-2J/cm2 ? 30 day) were established. The mice were randomly divided into four groups: control, UVB radiated groups (Water model, 10%MFP, 10%VitC). The ultrastructures of skin were observed by electromicroscope. The expression of Bcl - 2 protein and NOS were examined by immunohistochemical methods. The contents of MDA, the activities of GSH-Px, SOD and the T-AOC in the supernates of skin of those mice were detected by biochemical methods. RESULTS The large dilatant vacuolations and few rough endoplasmic reticu-lum in fibroblasts and epidermic cells of mice in UVB model group were observed under electromicroscope. MFP could keep the ultrastructure of epidermis and fibroblasts in the mice of MFP groups normal. MFP could enhance the expression of Bcl-2 protein and inhibit the ac-tivitiy of NOS(P
