Abstract
Novel linear hydrophilic polyurethane polymers are presented. The polymers provide outstanding soil-release, anti-soil redeposition and anti-static properties when applied to natural and synthetic textile substrates, especially textile substrates containing polyester fibers. These polyurethanes are particularly useful in detergent compositions.
