摘要:

Emulsion-containing cosmetic compositions, wherein the emulsion comprises an aqueous dispersion of 15 to 40% solids, by weight, of an enzymatically degraded starch, which starch has been debranched by treatment with an alpha-1,6-D-glucanohydrolase to yield up to 100%, by weight, short chain amylose, are provided herein. Also provided are oil-free cosmetic compositions and cosmetic stick compositions, comprising 1 to 16% enzymatically debranched starch; 2 to 35% water; 35 to 90% hydrophobic base, selected from the group consisting of oil, wax and fat, and 5 to 20% emulsifier(s), with the balance of the compositions comprising one or more adjuncts selected from dye(s), fragrance(s), flavor(s), sunscreen agent(s), opacifier(s), and filler(s). Also provided is a method for formulating a cosmetic stick composition.
