  • 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.

  • 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.

  • Patent number: 8747823
    Abstract: A composition containing sulfonated keratin with molecular weight distribution of about 96.8% 100 kDa to 100 Da and about 3.2% 250 kDa to 100 kDa, at least one cationic surfactant, and optionally an aqueous carrier. Generally the keratin is produced by a method involving treating wool with about 0.5 to about 1.0N NaOH in a bath volume:wool weight of about 5:1 to about 10:1 at about 40° C. to about 65° C. for about 4 to about 8 hours with dosing about every 1 to 3 hours with about 1% to about 10% by weight of bath of hydrogen peroxide. Also a method for treating a keratin based substrate involving contacting or applying the substrate (e.g., hair) with the composition.

  • Patent number: 8568701
    Abstract: The present invention is related to surfactant-based formulations comprising the polyelectrolytes and blends of such polyelectrolytes with non-cellulosic cationic polysaccharide polymers wherein the surfactant is a phosphate ester. The surfactant-based formulations exhibit improved clarity of the resulting formulations, their improved conditioning of keratin substrates, textile substrates, and hard-surface substrates, their improved deposition of dispersed phase materials onto keratin substrates, textile substrates, and hard-surface substrates, their improved lather performance, and their improved rheology in applications such as personal care and household care products and textile applications.
