Abstract
A detergent composition and method may have the soil anti-redeposition 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 modified vegetable protein material such as a soy protein isolate 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 soy protein derivatives have also been shown to be effective anti-redeposition agents.
