Abstract

The present invention relates to a polymeric material comprising units capable of having a cationic charge at a pH of from about 4 to about 12; provided that said polymeric material has an average cationic charge density from about 2.75 or less units per 100 daltons molecular weight at a pH of from about 4 to about 12. The polymeric material is a suds enhancer and a suds volume extender for hand dishwashing compositions and personal care products such as soaps, shaving cream foam, foaming shaving gel, foam dephiliatories and shampoos. The polymers are also effective as a soil release agent in fabric cleaning compositions. The polymers are also useful in agrochemical foam, fire-fighting foam, hard surface cleaner foam, and coagulant for titanium dioxide in paper making.
