Abstract: Compositions including polycarbodiimide together with latex compounds to enhance the quality of the keratinous substrates. The present invention relates to a cosmetic treatment and process for treating keratinous materials, in particular for nail polishes and other treatments, where, according to the process, the polycarbodiimide and latex actives may be applied in a nail treatment that is a single step or at least two sequential steps. The ratio of the latex compound to the polycarbodiimide compound is in the range from about 50:50 to about 95:5, and the composition comprises 10 to 100% of a combined amount of the polycarbodiimide compound and the latex compound, by weight, of the entire composition. It is in particular a nail treatment composition and process for providing one or more of improved adhesion, water resistance, and shine through crosslinking between the actives, thereby imparting long wear, good shine, nail protection, and easy removal.
