DETERGENT COMPOSITION COMPRISING HYDRATE-FORMING SALT PARTICLES COATED WITH BETAINE

摘要

The present invention relates to solid detergent composition having improved solubility. The present inventors have investigated ways of providing solid detergent composition that has improved solubility in cold-water conditions specifically at temperatures lower than 10°C, more preferably lower than 5°C, and towards providing a coated filler agent for use in detergent composition, which coated filler agent inhibits formation of crystalline masses, which are difficult to disperse, and dispense. After intensive investigations made for the purposes of solving the problem, the inventors have found that a filler agent having high dispersibility and solubility in cold water at temperatures lower than 10°C, more preferably lower than 5°C can be obtained by at least partially coating the hydrate-forming salt with a betaine class of zwitterionic compound.
