Abstract:
A powder-based solid cosmetic composition prepared by a process comprising:mixing a composition comprising a powder, a film forming polymer and a volatile solvent to form a mixture; and volatilizing said volatile solvent, wherein said film forming polymer is selected from the group consisting of a vinyl polymer, a poly(N-acylalkyleneimine)modified silicone and a vinyl silicone block copolymer and has a modulus of elasticity of not greater than 200 Kg/cm2, wherein the powder-based solid cosmetic composition has a porosity of at least 0.4, a hardness of not greater than 75 and an impact resistance of at least 5, wherein the impact resistance is defined as the number of dropping times until a crack appears in a molded product of the powder-based solid cosmetic composition, said molded product having a diameter of 54 mm and a thickness of 4 mm after press-molding and drying at 50Â° C. at normal pressure for 3 hours, when said molded product is dropped from a height of 50 cm onto a plywood board 25 mm thick.
