Mascara composition based on waxes and keratin derivatives

摘要: These wax-based mascara compositions have cosmetic properties which are improved by the presence, in combination with waxes, of keratin sulphonic derivatives formula ##STR1## K denotes residue, and M + H , a cation derived from an alkali metal or magnesium, N (R) 4 radicals R being identical different each denoting alkyl hydroxyalkyl radical containing at most carbon atoms, unit A 3 to 15% weight derivative only modified protein chain keratin. The (I) act both as cohesion agent thickener, enabling sheathing be produced on eyelashes immediate adhesion flexible film-forming effect.
