  • Patent number: 9289631
    Abstract: Personal care compositions comprising a polymer-bound UV absorber are described that provide enhanced properties, including customizable UV spectrum protection, broad-spectrum UV spectrum protection, water resistance, and labile UV stabilization. The polymer comprises anhydride functionality, such as maleic anhydride or a derivative thereof, and the UV absorber contains at least one hydroxyl, primary amine, or secondary amine group. The personal care compositions may be used to treat and/or protect against burns, cancers, erythema, lentigo (“liver spots”), keratotic lesions, wrinkles, and cellular changes of the skin; and/or color changes, embrittlement, lack of luster, tangles, split ends, and/or unmanageability of the hair.

  • Patent number: 8673272
    Abstract: Disclosed are novel ultraviolet-absorbing compounds produced by two embodiments. By a first embodiment, the ultraviolet-absorbing compound is derived from at a first reactant being a UV absorber comprising a carbon-nitrogen triple bond and a second reactant having amine functionality. By a second embodiment, the ultraviolet-absorbing compound is derived from a first reactant being a UV absorber comprising amine functionality and a second reactant comprising a carbon-nitrogen triple bond. In both embodiments of the invention, the second reactant may be a small molecule, a monomer, a macromolecule, a biomolecule, or a polymer. The invention's ultraviolet-absorbing compounds are directed toward formulations and applications that serve to protect against UV radiation in any art.
