Abstract
A nail enamel composition which contains, in a cosmetically acceptable solvent system containing diacetone alcohol and at least one additional solvent chosen from C1-C6 alkyl acetates and C1-C6 alkyl alcohols, at least one film-forming substance and at least one urea-modified thixotropic agent.
