Abstract
The present invention relates to fabric and textile conditioning compositions with improved particulate soil cleaning, containing particular combinations of cationic polymers and anionic surfactants in combination with a polyvinylpyrrolidone/amphiphilic carboxy containing polymer anti-redeposition system. The cationic polymers are preferably below a particular molecular weight to afford optimal cleaning and conditioning, and must be present in an effective amount to yield a substantial conditioning benefit. A method of conditioning articles using the inventive compositions is also disclosed.
