J&J Patents Composition with UV Radiation Absorbing Polymer

US Patent No. 8,025,868 B2; Johnson & Johnson Consumer Companies, Inc., Skillman, NJ, has patented compositions comprising an ultraviolet radiation-absorbing polymer. It entails a blend containing a UV-absorbing polymer comprising the polymerization reaction product of a first ethylenically unsaturated monomer comprising a first pendant group that comprises a UV-absorbing moiety, and a second pendant group selected from the group consisting of H, or C1 to C12 alkyl; and a second ethylenically unsaturated monomer selected from the group consisting of monomethacryloxypropyl polydimethylsiloxane and methacryloxypropyl tri-methoxysilane, wherein the number of repeat units of said first reacted monomer per molecule is from one to approximately 6000 and the number of repeating units of said second reacted monomer per molecule is from about two to about 6300. The UV-absorbing polymer has an average molecular weight of at least 2000 and comprises at least 5 mole percent of the first pendant group. The second UV-absorbing polymer comprises a UV-B absorbing moiety. The blend is capable of providing both synergistic SPF and synergistic PFA protection over a mass percent range of the first and second UV-absorbing polymers of at least 40%.



Cosmetic with Enhanced Wear
US Patent No. 8,025,869 B2; L’Oréal, France, has patented a cosmetic composition comprising a polypropylsilsesquioxane film forming resin; volatile solvent; and optionally a colorant. The cosmetic composition is anhydrous and is free from any non-volatile solvent or plasticizer.



Colgate-Palmolive Patents Fabric Softener
US Patent No. 8,026,205 B2; Colgate-Palmolive has been granted a US patent for a fabric softening composition. It is comprised of 0.01- 50% of a cationic or nonionic softening compound, perfume and a polymeric material capable of retaining volatile perfume ingredients comprising at least 0.001% by weight of a cross-linked polymer comprising at least one vinyl monomer and 50-60% by weight of acrylamid, wherein the polymer excludes diallyl dimethyl ammonium chloride and quaternized dimethylaminoethyl methacrylate; and 5,000-100,000 ppm of a divinyl cross-linking agent.



Decreasing Pigmentation Of Hyperpigmented Skin
US Patent No. 8,025,893 B2; Bor Sinan Tas of Turkey has patented a method to decrease pigmentation of hyperpigmented skin. It comprises administering cyclopamine or another compound that selectively inhibits Hedgehog/Smoothened signaling in a dosage that decreases the amount of pigmentation in the area.



Two-Part Hair Dye Patented by Kao
US 8,025,702 B2; Kao Corp., Tokyo, has patented a two-part hair dye composition. It contains an alkali agent, hydrogen peroxide and a non-aerosol type foamer container for discharging the mixture as foam. The mixture solution has two components—A is 0.1 to 10% by mass of a nonionic surfactant and B is 0.1 to 5% by mass of a cationic surfactant. The mass ratio of component A to component B is 1 to 100.



P&G Patents Surfactant Concentrate
US Patent No. 8,026,203 B2; The Procter & Gamble Company has patented a surfactant concentrate that is comprised of approximately 75% of an essentially completely neutralized anionic sulphated surfactant and 5-25% carboxylic acid, of which about 4% to about 96% of the carboxylic acid is in its free acid form. The anionic sulphated surfactant comprises an alkyl alkoxy sulphate, wherein the alkyl group contains from about 10 to about 22 carbon atoms and the alkoxy group contains from about 1 to about 15 alkoxylate moieties and further wherein said concentrate comprises 0% of a nonionic surfactant.



Anionic Surfactant Granule
US 8,026,204 B2; Kao Corp. has patented a method for producing an anionic surfactant granule. It entails granulating an anionic surfactant powder in a granulator with agitating blade while adding water. The temperature of the granule is higher by 0.5 to 30°C than the boiling point of water under a pressure of the inside of the granulator.



Hair Color Patents Awarded to L’Oréal
Beauty giant L’Oréal has been awarded a pair of patents related to its hair care business.

US Patent No. 8,025,700 B2 covers a method of treating keratinous fibers for partial bleaching. It is comprised of exposing at least one region being treated to at least one light pulse laser, a duration over which a light power of the pulse reaching the fibers is equal to or greater than one half of a peak power being between about 100 ps and about 1 μs. The pulses occur at a frequency greater than about 10 kHz.

In US Patent No. 8,025,701 B2, the beauty and hair care company has patented the use of natural hues for coloring human hair. The composition comprises at least one natural dye chosen from orceins, alizarin, purpurin, carminic acid, kermesic acid, purpuroqallin, protocatechaldehyde, indigo, curcumin, spinulosin, apiqenidin, chlorophyllin, sorghum, and cochineal carmine and at least one organic solvent.
