Water-soluble viscosity increasing agent and detergent composition containing the same.

摘要

A water-soluble viscosity increasing agent consisting essentially of: (i) an ester of a 40 to 400 moles ethylene oxide adduct of polyhydric alcohol and a C8-36 branched fatty acid, (ii) an ester of polyethylene glycol having average molecular weight of 2,000 to 20,000 and a C8-36 branched fatty acid, and (iii) a 40 to 400 mole ethylene oxide adduct of an ester of a polyhydric alcohol and a C8-36 branched fatty acid. The viscosity increasing agent can increase the viscosity of solutions of various surface active agents, while maintaining their stability and solubility in the solutions. When it is formulated to a detergent suitable for washing textiles, tablewares, human skins, hairs and the like, it can provide a detergent composition with a proper viscosity as well as a good detergency.
