  • Mascara comprising a mixture of hard waxes and of film-forming polymer
    Patent number: 6274131
    Abstract: A mascara composition for curling and thickening eyelashes comprising: a waxes-in-water emulsion of at least one mixture of hard waxes (I), the mixture of waxes (I) containing at least three waxes having melting points ranging from 77° C. to 110° C., the mixture of waxes (I) is present in a content of at least 10% by weight relative to the total weight of the composition, and the mixture of waxes (I) is in the form of particles of at least 1 &mgr;m in size, and at least 0.1% by weight of a polymer system containing at least one film-forming polymer, where the polymer system is capable of forming a film which produces, at a concentration of 7% in water, a greater than 1% retraction of isolated stratum corneum at 30° C. and under a relative humidity of 40%.

  • Composition for coating keratin fibres
    Patent number: 6264933
    Abstract: A cosmetic composition for coating keratin fibers, in particular the eyelashes. The composition can provide a waterproof coating that curls the keratin fibers. The composition comprises at least one lamellar filler, and an aqueous phase dispersed in a liquid fatty phase containing at least one volatile organic solvent. The aqueous phase contains a polymer system comprising at least one film-forming polymer which is dispersed in the aqueous phase in the form of solid particles.

  • Mascara containing wax(es) and carboxyl-functional film-forming polymer aqueous dispersion
    Patent number: 5620693
    Abstract: A cosmetic composition comprising in admixture a pseudolatex containing particles of a film-forming polymer having carboxylic acid functional groups, the particles having a mean diameter of between 10 and 300 nm and at least one wax having a melting point of between 60.degree. C. and 110.degree. C. in a proportion of between 2 and 40% by weight with respect to the total weight of the composition. The carboxylic acid functional groups of the polymer are neutralized to a degree of neutralization of between 10 and 80% by a nonvolatile monobasic agent. The pseudolatex is present in a proportion of between 0.8 and 20% by way of solids with respect to the total weight of the composition. The cosmetic composition, used as a mascara, provides enhanced lengthening and beautiful curvature on eyelashes.
