Unilever PLC, Unilever N.V. and Hindustan Unilever Limited
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.

Fragrance compositions
Disclosed is a composition comprising a fragrance oil of specified composition, an entrapment material, and at least 50% by weight of a volatile solvent. The entrapment material is selected from the group consisting of polymers; capsules, microcapsules, and nanocapsules; liposomes; pro-perfumes; film formers; absorbents; cyclic oligosaccharides and mixtures thereof. The invention provides compositions wherein the fragrance character remains detectable for 2–6 hours after the composition has been applied to the substrate.

The Procter & Gamble Company
Fragrance compositions
The present invention relates to a composition comprising a fragrance oil as specified in the patent and an entrapment material that is selected from the group consisting of polymers; capsules, microcapsules, and nanocapsules; liposomes; film formers; absorbents; cyclic oligosaccharides and mixtures thereof. The perfume raw material and the entrapment material exist in an associated form on the substrate. The weight ratio of high odor impact perfume raw materials that have an odor detection threshold of less than, or equal to, approximately 50 parts per billion to entrapment material within the associated form falls in the range of approximately 1:20 to approximately 20:1.
