FOAM-CONTROLLING DETERGENT ADDITIVE COMPOSITIONS AND USE THEREOF IN DETERGENT COMPOSITIONS

摘要

A detergent additive composition comprising a mixture of: (a) a dispersion of polydimethylsiloxane foam-controlling agent in an ethoxylated nonionic surfactant having a hydrophilic-lipophilic balance of from 9 to 13 and a melting point of from 5 DEG C to 36 DEG C, and (b) a dispersion of hydrophobic silica foam-controlling agent in a water-soluble or water dispersible organic carrier having a melting point of from 38 DEG C to 90 DEG C. The additive composition is suitable for use in a detergent composition containing at least 12% of a mixture of anionic and nonionic surfactants to provide improved detergency and foam regulation characteristics across the range of wash temperature conditions.
