Malodor reduction of cosmetic products
Disclosed are malodor-free skin care compositions comprising an adsorbable solvent and an insoluble particle in an adsorbable solvent-insoluble particle complex. The complex is suitable to adsorb components with malodor to yield a skin care composition free of offensive odors like those generated from the oxidation of conjugated linoleic acid.

Cosmetic composition for keratinous substrates with triarylmethane compounds
Disclosed is a method of imparting color onto keratinous substrates. The method involves contacting the substrate with a composition comprising at least one triarylmethane dye molecule, at least one film forming agent, and at least one solvent, and then irradiating the substrate with a flash of light. The dye molecule is chosen from polymeric triarylmethane dye molecules, copolymeric triarylmethane dye molecules, oligomeric triarylmethane dye molecules, and mixtures thereof.

Cosmetic composition comprising a polymer and fibres
The invention relates to a composition comprising, in a physiologically acceptable medium containing a fatty phase, a polymer with a weight-average molecular mass of less than 100,000 and in particular ranging from 1,000 to 30,000, and fibers. The polymer consists of a polymer skeleton containing hydrocarbon-based repeating units containing at least one hetero atom; fibers are linked to these units. Optionally the polymer may have pendent fatty chains and/or terminal fatty chains, which may be functionalized, containing from 6 to 120 carbon atoms. The invention especially relates to a mascara.
