  • Patent number: 9962327
    Abstract: The present invention relates to a cosmetic or dermatological composition of sol/gel type for making up and/or caring for keratin materials characterized in that it comprises the product resulting from the reaction: (a) of at least one alkoxysilane monomer or oligomer of formula (I) R1xSi(OR2)(4-x) or of formula (II) [R1y (OR2)z SiO ((4-?-?)/2)]? in which R1 represents, independently, a nucleophilic group other than a hydroxyl, or a (Ci-C2o)alkyl group, R2 represents, independently, a (Ci-Cio)alkyl group, and (b) of an amount of water corresponding to a number of moles of water, determined according to the following equation: X?(llAlkoxysilanes×llbAlkoxy groups)/nH2o with nH2o=Number of moles of water, nAikoxysiianes=Number of moles of alkoxysilane compounds, nbAikoxy groups=Weighted mean of the number of alkoxysilane groups per alkoxysilane compound, and X is a number greater than 2. It also relates to an associated cosmetic process and an associated kit for coating keratin materials.

  • Publication number: 20050276770
    Abstract: A cosmetic product may be a lipcare and/or a lip makeup containing, as filler, polyurethane particles and less than 15% by weight of at least one of water and a water-soluble solvent. A cosmetic product may be a lipcare and/or a lip makeup containing, as filler, polyurethane particles in an amount such that a mean gloss of the product is at least 30. A method of preparing a cosmetic product may include employing, as filler, polyurethane particles in the cosmetic product such that a mean gloss of the product is not less than 30. A lip makeup process may include applying such a product to lips.
