摘要:
Compositions for inhibiting the formation of unwanted skin pigmentation combine high tyrosinase blocking capabilities with stability in cosmetic preparations, absence of significant cytotoxic effects and synergy of action. The active components of the compositions include extracts of certain selected plants, namely, mulberry, saxifrage, grape and scutellaria root; and, preferably, ethylenediaminetetraacetic acid (EDTA). These ingredients are combined with various cosmetically acceptable carriers to produce cream and lotion formulations capable of whitening skin safely and effectively.
摘要:
The invention relates to a polyose/fatty acid complex product. This complex product is the reaction product of at least one polyose with at least one fatty acid, in particular in the form of a halide or the anhydride. The fatty acid can be saturated or unsaturated and can comprise from 8 to 28 carbon atoms. This complex product has a high moisturizing capacity and, surprisingly, an emulsifying capacity and can be used to prepare valuable cosmetic or pharmaceutical compositions.
