Abstract
Water-based makeup compositions and methods for their preparation are disclosed. The compositions comprise a water-dispersible pigment having a nonionic coating, a lipid vesicle comprising one or more lipid components, and a cosmetically or pharmaceutically acceptable aqueous carrier, and possess unusual stability at low pH. A method for the preparation of such water-based makeup compositions is disclosed as well.
Claims25
A water-based makeup composition stable at an acidic pH range which comprises:
- (a) a water-dispersible metallic oxide having a nonionic coating in an amount of from about 0.1 to about 40 percent by weight of total composition;
- (b) a lipid vesicle comprising one or more lipid components in an amount of from about 0.1 to 80 percent by weight of total composition;
- and
- (c) a cosmetically or pharmaceutically acceptable aqueous carrier.
A water-based makeup composition stable at an acid c pH range which comprises:
- (a) a water-dispersible metallic oxide pigment having a nonionic coating in an amount of from about 0.1 to about 40 percent by weight of total composition, wherein the nonionic coating comprises dimethicone copolyol;
- (b) a lipid vesicle comprising one or more lipid components in an amount of from about 0.1 to 80 percent by weight of total composition;
- (c) a gellant;
- (d) a polyurethane;
- and
- (e) a cosmetically or pharmaceutically acceptable aqueous carrier.
A method for the preparation of a water-based makeup compositions stable at an acidic pH range comprising blending a water-dispersible metallic oxide pigment having a nonionic coating in an amount of from about 0.1 to about 40 percent by weight of total composition with a lipid vesicle in an amount of from about 0.1 to 80 percent by weight of total composition comprising one or more lipid components in a cosmetically or pharmaceutically acceptable aqueous carrier.
