Estimating the term…
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.
A polysaccharide polymer comprising a water soluble and water insoluble fraction wherein the water insoluble fraction constitutes between 0.4 wt % to 3 of the composition;
A process for forming a modified polysaccharide polymer comprising reacting a polysaccharide polymer with caustic, water, and a surfactant and further a derivatizing moiety selected from the group consisting of cationic, anionic, nonionic and amphoteric moieties and mixtures thereof.
A process for preparing a derivatized polygalactomannan comprising reacting polygalactomannan for sufficient time and sufficient temperature in the presence of water, caustic and at least one surfactant and an oxidizing agent and a derivatizing moiety selected from the group consisting of anionic compounds, nonionic compounds, amphoteric compounds, tertiary amine compounds, quaternary ammonium compounds, and mixtures thereof.
