  • Polysaccharide products with improved performance and clarity in phosphate ester surfactant-based aqueous formulations and process for preparation
    Patent number: 9561166
    Abstract: A personal or household care product includes cationic, nonionic or cationic/nonionic derivatized polysaccharide in combination with a phosphate ester surfactant. The derivatized polysaccharide polymer is formed by reacting the polysaccharide ester surfactant for a sufficient time and at a sufficient temperature in the presence of water, caustic, and at least one surfactant. The polysaccharide polymer may optionally be reacted with an oxidizing agent, hydrolytic or proteolytic enzymes, molecular weight reducing agents and a cationizing agent and nonionic agent. The formed derivatized polysaccharide has a lower clarity in water than in an aqueous surfactant system.
    Type: Grant
    Filed: February 20, 2012
    Date of Patent: February 7, 2017
    Assignee: HERCULES INCORPORATED
    Inventors: Anita N. Chan, Louis Patrick Dziuk, Jr., Paquita Erazo-Majewicz, Jashawant J. Modi, M. Olaf Michelson, Bruce Kevin Fillipo, Nabil Naouli
  • Polysaccharide products with improved performance and clarity in surfactant-based aqueous formulations and process for preparation
    Patent number: 8796196
    Abstract: A process for producing anionic, nonionic, amphoteric or cationic derivatized polysaccharide products which demonstrate high clarity in surfactant-based compositions. The polysaccharide polymer is reacted for a sufficient time and at a sufficient temperature in the presence of water, caustic, and at least one surfactant. The polysaccharide polymer may optionally be reacted with an oxidizing agent, hydrolytic or proteolytic enzymes, molecular weight reducing agents and a cationizing agent and nonionic agent. The formed derivatized polysaccharide has a lower clarity in water than in an aqueous surfactant system. The derivatized polysaccharide product can be used in personal care and or household care products.
