Abstract
Cosmetic varnish composition. At least one solvent, at least one nitrocellulose, at least one plasticizer, at least one resin, at least one otherwise unstable compound, preferably chosen from amino- and amido-functional compounds, and at least one stabilizer chosen from N-chlorosuccinimide and boric acid.
