摘要:
Cosmetic compositions are provided, which are capable of forming a cosmetic film on a human integument when applied thereto. Cosmetic compositions according to the invention typically include a cosmetically acceptable vehicle, optionally, one or more colorants, and a pH-dependent film-forming polymer of poly(methacrylic acid-co-methyl methacrylate) having a ratio of methacrylic acid to methyl methacrylate of about 1:1 to about 1:2, an acid value of from about 150 to about 350 mg KOH/g, and a weight average molar mass between about 100,000 and about 150,000 g/mol. The compositions are capable of forming an adherent film on the integument that is substantially resistant to removal by water at a first pH, but readily dispersible or soluble in water at a second pH higher than said first pH.
