Patent number: 6793684Abstract: A fabric care composition, which is adapted for use in a domestic laundering process, comprises an anionic polymer which is capable of self cross-linking and/or of reacting with cellulosic fibers, such as cotton, and a textile compatible exhaustion agent which is also a fabric conditioner. The polymer may be a carbamoyl sulphonate terminated poly(ether) urethane or a bunte salt terminated polymer. The polymers can increase the dimensional stability of the fabric, improve its surface color definition after washing, impart a softer handle and improve its crease recovery properties.Type: GrantFiled: August 29, 2002Date of Patent: September 21, 2004Assignee: Unilever Home & Personal Care USA, division of Conopco, Inc.Inventors: Anthony Nicholas Jarvis, Andrew Philip Parker, Philip John Sams
