  • Patent number: 8846154
    Abstract: Compositions, methods, apparatuses, kits, and combinations are described for permanently or temporarily re-designing, decorating, and/or re-coloring a surface. The compositions useful in the present disclosure include a décor product formulated to be applied and affixed to a surface. If desired, the décor product may be substantially removed from the surface before being affixed thereto. If a user desires to remove the décor product, the décor product may be removed by, for example, vacuuming, wet extraction, chemical application, and the like. If the user desires to affix the décor product to the surface in a permanent or semi-permanent manner, the décor product may be affixed by applying energy thereto in the form of, for example, heat, pressure, emitted waves, an emitted electrical field, a magnetic field, and/or a chemical. The décor product may also be part of a kit or in conjunction with a design device, such as a stencil, to control the application of the décor product to a surface.

  • Patent number: 6046292
    Abstract: Mesogens are provided based on substituted unsaturated carboxylic acids such as acrylic and methacrylic acid. Substitution of a variety of hydrophobic tails onto the carboxylic acid or acid derivative via the vinyl carbon proximal to the carbonyl of the carboxylic acid results in mesogens that are capable of forming thermotropic and single-phase lyotropic mesophases over a broad range of compositions. The mesophases can be polymerized to lock in the ordered phases.

  • Patent number: 6007769
    Abstract: The present invention relates to single-phase soap gels and viscous soap compositions which are produced by alkanolamine neutralization of a fatty acid above the Krafft point. These compositions are robust, biodegradable, and are insensitive to temperature changes. The compositions also exhibit excellent cleaning properties and may be used as laundry cleaning agents, oven cleaners, hard surface cleaners, and disinfectants and air fragrancing compositions.

  • Patent number: 5858345
    Abstract: Ophthalmic compositions containing biocompatible, bioadhesive polymerizable amphipathic mesophase materials useful for repairing retinal tissue tears or retinal detachments are disclosed. In one embodiment, the polymerizable materials, which comprise substituted fluoroalkyl or perfluoroalkyl monomers having anionic, cationic, and/or nonionic surface active functionality in the unsaturated fluorophobic ends, are polymerized in vivo to provide effective, long-lasting repair of torn, ruptured or detached retinal tissue. Ophthalmic applications of these materials are not limited to retinal repair.

  • Patent number: 5004598
    Abstract: This invention relates to stable oil-in-water emulsions and to products based on such emulsions which contain a modified polymer which is a copolymer of a preponderant amount of an acrylic acid and a smaller amount of a long chain acrylate monomer which modified polymer renders the emulsions stable for over a year at room temperature and which imparts to the emulsions the quick breaking property whereby the emulsions break on coming in contact with an electrolyte or skin, instantaneously coalescing and releasing oil from the emulsions.
