  • Hair modification composition and method therefor
    Patent number: 11478412
    Abstract: A composition and a process for modifying hair are disclosed. The process includes coating hair fibers with a composition comprising propylene carbonate and a glycol selected from at least one of propylene glycol, 1,3-propane diol, dipropylene glycol, tripropylene glycol, and mixtures thereof and contacting the coated hair with a heating appliance at a temperature of at least 150° C. for a sufficient time to modify the hair fibers.
    Type: Grant
    Filed: April 11, 2019
    Date of Patent: October 25, 2022
    Assignee: Lubrizol Advanced Materials, Inc.
    Inventors: Murat Kadir, Wing K. Li, Carole A. Lepilleur, Jean H. Xavier, Narjis A. Askar
  • ENHANCED SILICONE DEPOSITION COMPOSITIONS AND METHOD THEREFOR
    Publication number: 20220160611
    Abstract: The disclosed technology relates to stable conditioning shampoos comprising silicone oil and a fermentation derived cellulose (FDC) component. The FDC component provides good suspension of particulate and insoluble materials such as aesthetic beads and mica in surfactant-based systems, as well as enhances the deposition of silicone conditioning agents to keratinous substrates such as the hair and skin.

  • Hydrolytically Stable Multi-Purpose Polymer
    Publication number: 20120237465
    Abstract: The present invention relates to compositions containing hydrolytically stable multi-purpose polymers that are polymerized from a monomer mixture comprising: at least one amino-substituted meth(acrylate) (ASMA) monomer or salt thereof; and at least one nonionic vinyl (NIV) monomer, wherein the monomer mixture optionally comprises one or more of at least one vinyl associative (VA) monomer; at least one vinyl surfactant (VS) monomer; and/or at least one polymerizable silicone macromer (PSM) and wherein the monomer mixture further optionally comprises one or more of at least one crosslinking (XL) monomer; at least one chain transfer agent (CTA); and/or at least one polymeric stabilizer. The multi-purpose polymers of the present invention can also be prepared from monomer mixtures containing chain transfer agents or other functional components commonly utilized in polymerization processes.
