  • Publication number: 20170367950
    Abstract: The present invention relates to a cosmetic and/or dermatological composition comprising, in a physiologically acceptable medium: a) one or more alcohols comprising at least 20 carbon atoms, b) one or more fatty acid esters, said ester comprising at least 24 carbon atoms, and being selected among A) those corresponding to the formula (I) below: R—COO—R???(I) in which: R and R?, which may be identical or different, denote a saturated or unsaturated, linear or branched, hydrogenated or non-hydrogenated hydrocarbon-based group comprising from 12 to 30 carbon atoms and preferably from 14 to 24 carbon atoms, and B) di- or triesters of glycerol and of C12-C30 fatty acids; and c) at least one or more thickeners which are not xanthan gum. Another subject of the invention is a process for mattifying the skin and/or reducing the shininess thereof. Another subject of the invention is the use of said fatty acid ester as agent for mattifying keratin materials such as the skin.

  • Patent number: 6740313
    Abstract: A cosmetic and/or dermatological composition that produces on the skin a long-lasting and non-covering coloration similar to that of a natural tan comprising, in a cosmetically acceptable medium, at least one pigment, which may be obtained by extraction with an organic or aqueous-organic solvent of a culture medium of micromycetes of the Monascus type, as well as the use of the composition for giving the skin a long-lasting and non-covering coloration similar to that of naturally tanned skin.

  • Patent number: 6511656
    Abstract: Methods for manufacturing cosmetic and dermatological compositions for coloring the skin; and composition, for example, an emulsion, comprising (1) at least one aqueous phase, (2) at least one fatty phase, (3) at least one flavylium salt which is unsubstituted in position 3; which is substituted with at least one radical chosen from hydroxyl and alkoxy radicals; and which is, for example, obtained at least one of synthetically, from a plant extract, and from an enriched plant extract, in an amount which is effective for artificially coloring the skin, for example, effective for obtaining, 30 minutes after application of the emulsion to a fair skin in an amount of 2 mg/cm2, a darkening of the skin color characterized in the L*a*b* colorimetric measuring system by a &Dgr;L* ranging from −0.5 to −20, and (4) at least one organomodified silicone, where the emulsion is configured as at least one of a cosmetic and a dermatological emulsion.
