Abstract
The present invention is directed to a transfer resistant and long wear cosmetic composition having a unique gel-like texture with good pickup, payoff, and spreadability properties, as well as a silky smooth feel containing: (a) at least one polyamine; (b) at least one oil-soluble polar modified polymer; (c) water; (d) at least one volatile solvent; (e) at least one non-volatile solvent; (f) at least one water soluble surfactant; (f) at least one colorant; and (g) at least one oil absorbing powder.
Claims6
A cosmetic composition comprising:
- (a) a reaction product of at least one polyamine having a molecular weight of from 500-200,000 and at least one oil-soluble polar modified polymer, wherein the reaction product is water-insoluble half acid and half amide crosslinked reaction product and wherein the polar modified polymer comprises maleic anhydride groups and the reaction product is produced by reacting the maleic anhydride groups of the polar modified polymer with primary amine group of the polyamine in the presence of water and at a temperature below 100° C. such that dicarboxylic acid groups associated with the maleic anhydride groups open to interact with protonated primary amines of the polyamine through ionic interaction to form a hydrophobic network that act as supramolecular capsule;
- (b) water in an amount of from 0.5 to 50% by weight, based on the weight of the composition;
- (c) at least one volatile solvent other than water;
- (d) at least one non-volatile solvent capable of solubilizing the oil-soluble polar modified polymer;
- (e) at least one water soluble surfactant;
- (f) at least one colorant;
- and
- (g) at least one oil absorbing powder.
