Method of improving the soil anti-redeposition properties of washing detergents and products.

摘要

A detergent composition may have its soil anti-redeposition properties significantly and unexpectedly improved by incorporating into it an effective amount of an anti-redeposition agent which 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 anti-redeposition 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.
