  • Patent number: 7727289
    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 that is 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 is formulated to be removed by a number of methods including, 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 to the surface 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.

  • Publication number: 20050124514
    Abstract: A composition suitable for use in personal cleaning or detergent soap bars, which includes a sulfonated fatty acid or alpha sulfonated alkyl ester, and methods for producing such a composition. The composition and methods exhibit efficient processing and allow for formation of cleansing or detergent bars with improved hardness, improved resistance to marring and improved processability to marring, lower wear-rate and decreased mush formation during consumer use.

  • Publication number: 20010027171
    Abstract: Disclosed are hair care compositions and methods for preparing such compositions which provide the benefits of cleaning, conditioning, curl retention, styling and setting properties simultaneously to hair in the application of a single product. The hair care compositions contain fatty alkyl amine salts, long chain quaternary ammonium salts and mixtures thereof of anionic styling polymers in a non-anionic surfactant system, wherein the surfactant system contains nonionic surfactants, semi-polar nonionic surfactants, amphoteric surfactants and mixtures thereof. The styling, setting and conditioning agents are present in the form of fatty alkyl amine salts or fatty quaternary ammonium salts which form anionic styling polymer particulate networks upon dilution in water. These networks are dispersed in the aqueous non-anionic surfactant system and are stabilized and thickened by optional swellable polymer thickening agents.
