A liquid nail polish which imparts improved flexural strength to the human nail and inhibits splitting when applied thereto as a coating. The nail polish formulation is characterized by the inclusion therein, as a dissolved component, of a small but effective amount of a terpolymer comprising a copolyamide consisting essentially of recurring units of equimolecular proportions of caprolactam, laurolactam and hexamethylene diamine adipate. Typically, said terpolymer is first dissolved in a mixture of trichloroethane and ethyl alcohol, and this liquid solution is added in a small quantity to a stock liquid nail polish formulation so that a final formulation containing a small but effective amount of said dissolved terpolymer is produced, e.g. a formulation containing in the range of about 0.001 to 0.1% by weight of said dissolved terpolymer.
