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.

Polysaccharide products with improved performance and clarity in phosphate ester surfactant-based aqueous formulations and process for preparation

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.

The present invention is related to the use of glyoxal-free compositions, more particularly, to the use of hydroxyethylcellulose agglomerated with low molecular weight hydroxyethylcellulose in consumer products, in particular, pharmaceutical, personal care (excluding oral care compositions), as well as household care applications.

Use of agglomerated hydroxyethylcellulose in pharmaceutical, personal care and household care applications

The present invention is related to the use of a non-cellulosic cationically modified polysaccharide in cleaning compositions and more particularly to a surfactant based cleansing composition comprising, a surfactant, a non-cellulosic cationically modified polysaccharide and a solvent for use in personal care composition, household care composition or an institutional care composition.

Cleansing formulations comprising non-cellulosic polysaccharide with mixed cationic substituents

A cationic, oxidized polysaccharide or derivative thereof that has a mean average molecular weight (Mw) having a lower limit of 50,000 and an upper limit of 1,000,000 and an aldehyde functionality content of at least 0.001 meq/gram is used in personal care and household care compositions. This cationic, oxidized polysaccharide is prepared in continuous or batch processes using hydrolytic reagents, oxidizing reagents, or combination of hydrolytic reagents and oxidizing reagents. Personal care or household care compositions are prepared by adding the cationic, oxidized polysaccharide to a personal care or household composition containing at least one active ingredient other than the cationic, oxidized polysaccharide of this invention.
