Abstract
The present invention is directed to a hydrating and moisturizing solid emulsion lipstick composition, capable of imparting enhanced shine and coverage, containing: (a) at least one polyamine; (b) at least one polar modified polymer; (c) water; (d) at least one non-volatile solvent; (e) at least one wax having a high melting point; and (e) optionally, at least one colorant.
Claims14
An emulsion composition, in solid form, comprising:
- (a) at least one polyamine;
- (b) at least two polar modified polymers;
- (c) water;
- (d) at least one non-volatile solvent capable of solubilizing the at least one polar modified polymer;
- and
- (e) at least one high temperature melting wax,
- wherein one polar modified polymer is an oil-soluble polar modified polymer comprising at least one C2-C4 monomer and modified with at least one hydrophilic unit, and having a weight-average molecular weight of less than or equal to 25,000 g/mol and a melting point above 75° C.,
- wherein a second polar modified polymer is an oil soluble high carbon polar modified polymer comprising at least one C22-C40 monomer modified with at least one hydrophilic unit, and having a weight-average molecular weight of less than or equal to 30,000 g/mol and a crystallinity of 8% to 60%, and
- wherein the composition is free of emulsifiers and/or silicone fluids.
