US Patent No. 9,643,032 B2: L'Oréal, Paris, has patented a regimen for artificially coloring the skin that entails topically applying onto the skin a composition containing an effective amount of dehydroascorbic acid and/or a monomeric derivative thereof of formula (I) and/or an isomer thereof of formula (I′) and/or a polymer derivative thereof:
in which OR1 and OR2, which may be identical or different, are each OH; a linear or branched, saturated or unsaturated C1-C30 alkoxy radical; a glycoside; a linear or branched, saturated or unsaturated C1-C30 aliphatic carboxylic acid ester, which may be substituted with an aryl group or a heterocycle; an aryl or heterocyclic carboxylic acid ester which may be substituted with at least one linear or branched, saturated or unsaturated C1-C30 alkyl radical; a phosphate group; a sulfate group, and also polymeric derivatives thereof, formulated into a topically applicable physiologically acceptable medium therefor; wherein the dehydroascorbic acid and/or a monomeric derivative thereof of formula (I) and/or an isomer thereof of formula (I′) and/or a polymer derivative thereof is combined with ascorbic acid or a derivative or salt thereof.
Compositions Having Improved SPF
US Patent No. 9,642,791 B2: L'Oréal, Paris, has patented a composition comprising at least one sunscreen active agent and at least one oil dispersion of acrylic polymer particles that comprises a C1-C4 alkyl (meth)acrylate polymer and at least one stabilizer selected from the group consisting of isobornyl (meth)acrylate homopolymers and statistical copolymers of isobornyl (meth)acrylate and of C1-C4 alkyl (meth)acrylate present in an isobornyl (meth)acrylate/C1-C4 alkyl (meth)acrylate weight ratio of greater than 4.
