METHOD OF IMPROVING THE SOIL ANTI-REDEPOSITION PROPERTIES OF WASHING DETERGENTS AND PRODUCTS

摘要

METHOD OF IMPROVING THE SOIL ANTI-REDEPOSITION PROPERTIES OF WASHING DETERGENTS AND PRODUCTS A detergent composition and method may have the soil antiredeposition properties significantly and unexpectedly improved by incorporating into the detergent composition an effective amount of an anti-redeposition agent. The anti-redeposition agent is a casein material which has been modified with an ionic monomer. Ionic monomers which have been found to be especially effective at improving the antiredeposition properties of washing detergent compositions are cationic epoxide monomers, cationic acrylate monomers and cationic chlorohydrin monomers. Anionic or carboxylated casein derivatives have also been shown to be effective anti-redeposition agents.
