  • Patent number: 5275811
    Abstract: What is provided herein is an improved hair spray resin composition including a terpolymer consisting essentially of a vinyl ester, preferably vinyl acetate, a water-insoluble or water-miscible alkyl maleate half-ester, preferably mono-N-butyl maleate and an N-substituted acrylamide, preferably N-t-butyl acrylamide, N-t-octyl acrylamide or N-[1-(2-pyrrolidonyl)ethyl]acrylamide, in the molar ratio of 1:0.6-0.8:0.08-0.12, respectively, and having a relative viscosity of about 1.2-2.0.

  • Patent number: 5223247
    Abstract: A hair spray composition is provided herein which is capable of delivering a fine finishing mist at a high resin solids level. The composition is substantially moisture resistant, provides a stiff resin film having excellent hair holding power, and has a relatively low concentration of volatile organic compounds therein. The composition of the invention attains its unique attributes by including therein a water soluble or dispersible alkylated polyvinylpyrrolidone (PVP) copolymer powders having a predetermined blend of two monomer components, one being PVP having a defined molecular weight (K-value 15-120, preferably 30-90) and concentration (80-99%, preferably 90-95%) and the other being an alkylene having a selected number of carbon atoms (C.sub.4 -C.sub.10, preferably (C.sub.6 -C.sub.8), linear or branched, in a defined concentration (1-20%, preferably 5-10%).

  • Patent number: 5221531
    Abstract: The present invention provides a polymer hair fixative comprising vinyl caprolactam, vinyl pyrrolidone, dimethylaminoethyl methacrylate and acrylate acid, in the form of sodium acrylate, an aqueous-based solution process for making such polymers, and water-based hair spray compositions including such polymer fixatives which meet VOC standards.

  • Patent number: 5196495
    Abstract: A hair spray fixative resin comprises a vinyl acetate/alkyl maleate half ester/N-substituted acrylamide terpolymer in a molar ratio of about 1.0 to 0.6-0.8 to 0.08-0.12, which is preferably produced by a suspension or solution polymerization process. Utilizing N-substituted acrylamides in place of isoborneol methacrylates in the terpolymer provides superior holding power over conventional hair fixative resins, at lower cost.

  • Patent number: 5182098
    Abstract: The present invention provides a terpolymer hair fixative comprising vinyl caprolactam, vinyl pyrrolidone and methacryloamidopropyl trimethylammonium chloride, an aqueous solution process for making such terpolymers, and water-based hair spray compositions which meet VOC standards.

  • Patent number: 5160729
    Abstract: What is described herein is a high water content hair spray composition which forms uniform, fine spray patterns having rapid drying characteristics and which provides excellent curl retention, and reduced curl droop properties. These results are achieved herein by incorporating a surface active agent or agents into the hair spray composition which agent or agents substantially decreases the surface or interfacial tension of the hydroalcoholic phase of the composition during use. The decreased surface tension of the water-based composition along the length of the hair shaft enhances its spreading tendencies so that substantially no droplets can form upon application of the composition of the hair. The surface active agent preferably is a surface lactive lactam; and, most preferably an N-alkyl pyrrolidone, where the alkyl group is a C.sub.4 -C.sub.22, branched or linear, alkyl group.

  • Patent number: 5126124
    Abstract: A hair spray resin compositon is provided herein which is capable of delivering a fine finishing mist at a high resin solids level. The composition is substantially moisture resistant, provides a stiff resin film having excellent hair holding power, and has a relatively low concentration of volatile organic compounds therein. The composition of the invention attains its unique attributes by including a predetermined blend of at least two hair spray resins, one being a relatively high molecular weight resin, and the other resin having a relatively low molecular weight. The latter resin is present in the composition in a substantially greater proportion than the higher molecular weight resin.
