Abstract
Abstract A nitrocellulose nail varnish containing at least one scleroprotein derivative selected from the group consisting of certain collagen hydrolysates, polypeptide esters, protein fatty acid condensates, and mixtures thereof. The novel nail varnish has a favorable effect on the properties of human nails and reduces and eliminates nail damage, even in the case of individuals with sensitive or easily damaged nails.
