  • 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.

  • Publication number: 20090087390
    Abstract: An oral care or household cleaner system contains a fluid polymer suspension (FPS) thickening agent. The FPS thickening agents comprises a water soluble/water swellable polymer, a polyol, and a hydrated thickening silica. The water soluble/water swellable polymer is selected from the group consisting of acrylic acid polymer, salts of acrylic acid polymer, acrylate, acrylamide polymer, polyvinyl pyrolidene, polyvinyl alcohol, clay and polysaccharide, excluding CMC. The functional systems may be formulations of oral care, for example as a dentifrice or as a household cleaner. A method of preparing the oral care or household cleaner system is also provided by adding a sufficient amount of a FPS that is compatible with the functional system to the system to thicken the functional system.
