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