Abstract
Use of a cellulose ester for reducing the drying time of a nail varnish, wherein the nail varnish comprises, in a solvent medium, nitrocellulose a dyestuff, the cellulose ester being present in a synergistic amount, relative to the amount of nitrocellulose, effective for reducing the drying time of the nail varnish.
Claims24
A process for reducing the drying time of a nail varnish composition, said process comprising:
- combining at least one cellulose ester with a nail varnish to form a nail varnish composition, said nail varnish composition comprising, in a solvent medium, said at least one cellulose ester, a film-forming polymer, and a dyestuff, wherein said film-forming polymer is nitrocellulose, wherein said dyestuff is present in said composition in an amount sufficient to dye said composition, and wherein said cellulose ester is combined with said nail varnish in a synergistically effective amount, relative to the amount of nitrocellulose, for reducing the drying time of said nail varnish composition.
