| Popis: | 107 in English The derivatives of PDMS(Polydimethysiloxane, 聚二甲基矽氧烷) are popularly used in the fields of personal care products in the recent years, and play a more-and-more important role in the applications of cosmetic fields. They provide end products with better feel of touching, easy and smooth spread capability and long-lasting protection on the skin. Particularly in applications for hair care and skin care products. This research differentiates the emulsification abilities, products stability, transparency, viscosity and particle sizes among silicone emulsifiers which contain variable silicone structure, emulsifier concentrations, ingredients of oil/water phase and thickener application. With the technique of refractive index matching, we expect our final formulation basing on skin sensation and visual transparency can be obtained. Developing transparent lotion or cream may help creating different applications of cosmetics. Followed by researches on silicone emulsifiers with different polyethers, new base materials will certainly add a lot of varieties on cosmetic fields. With the understanding for the unique properties of silicone and proper adjustments of formulations, stable and aesthetically pleasing cosmetic products can be made. Fully utilization of silicone emulsifiers is highly expected to promote and satisfy consumers’ needs in the future cosmetics business. |
