Abstract
Rinse-added fabric conditioning compositions containing cationic soil release polymers are much more effective than similar compositions containing nonionic soil release polymers for soil release. Most of the cationic soil release polymers are new compounds comprising a hydrophobic alkylene oxide/terephthalate portion which has a low molecular weight and at least a single cationic charge under use conditions.
