Abstract
The present disclosure relates to stable cosmetic compositions containing high amounts of hydroxypropyl tetrahydropyrantriol, and optionally containing 4-tert-cyclohexanol. The cosmetic compositions further include water, a plurality of emulsifiers, fatty alcohols, further fatty compounds, and thickening polymers. Methods for stabilizing the cosmetic compositions containing high amounts of hydroxypropyl tetrahydropyrantriol, and optionally 4-tert-cyclohexanol, and methods of treating the skin with the cosmetic compositions is also described.
Claims18
A cosmetic composition comprising:
- (a) about 12 to about 25 wt. % of hydroxypropyl tetrahydropyrantriol;
- (b) water;
- (c) about 0.1 to about 5 wt. % of one or more nonionic emulsifiers chosen from glyceryl esters having a Hydrophile-Lipophile Balance (HLB) of about 3 to about 8;
- (d) about 0.1 to about 5 wt. % of one or more nonionic emulsifiers having an HLB of about 16 to about 18 chosen from ethoxylated fatty acids, ethoxylated sorbitan fatty esters, and mixtures thereof;
- (e) about 0.1 to about 5 wt. % of one or more nonionic emulsifiers having an HLB of about 9 to about 15 chosen from alkylpolyglucosides, polyglycerol-based emulsifiers, sorbitan fatty esters, sugar fatty esters, polyol fatty esters, glyceryl fatty esters, ethoxylates thereof, or a mixture thereof;
- (f) about 1 to about 10 wt. % of one or more fatty alcohols;
- (g) about 5 to about 20 wt. % of one or more fatty compounds;
- and
- (h) one or more thickening polymers;
- wherein the composition is oil in water emulsion, and all percentages by weight are based on the total weight of the cosmetic composition.
A cosmetic composition comprising:
- (a) about 10 to about 40 wt. % of hydroxypropyl tetrahydropyrantriol;
- (b) about 30 to about 80 wt. % of water;
- (c) about 0.3 to about 5 wt. % of one or more nonionic surfactants chosen from glyceryl esters having an HLB of about 3 to about 10;
- (d) about 0.3 to about 5 wt. % of one or more nonionic emulsifiers having an HLB of about 16 to about 18 chosen from ethoxylated fatty acids;
- (e) about 0.5 to about 5 wt. % of one or more nonionic emulsifiers having an HLB of about 10 to about 15 chosen from alkylpolyglucosides, polyglycerol-based emulsifiers, sorbitan fatty esters, sugar fatty esters, polyol fatty esters, glyceryl fatty esters, ethoxylates thereof, or a mixture thereof;
- (f) about 1 to about 10 wt. % of one or more fatty alcohols having from 8 to 24 carbon atoms;
- (g) about 5 to about 20 wt. % of one or more fatty compounds;
- (h) one or more taurate polymers chosen from acrylamide/sodium acryloyl dimethyl taurate copolymer, hydroxyethyl acrylate/sodium acryloyl dimethyl taurate copolymer, ammonium acryloyldimethyl taurate/VP copolymer, sodium acrylate/sodium acryloyl dimethyl taurate copolymer, hydroxyethyl acrylate/sodium acryloyldimethyl taurate copolymer, or a mixture thereof;
- and
- (i) optionally, about 0.1 to about 5 wt. % of 4-tert-butylcyclohexanol;
- wherein the composition is an oil in water emulsion, and all percentages by weight are based on the total weight of the cosmetic composition.
