Patent number: 6592856Abstract: Hair conditioning shampoo compositions are provided which contain a combination of conditioning agents including emulsified silicones, cationic polymers and certain fatty acid polyesters of polyols. Suitable fatty acid polyesters are sucrose pentalaurate, sucrose tetraoleate, sucrose pentaerucate, sucrose tetraerucate, sucrose tetrastearate, sucrose pentaoleate, sucrose octaoleate, sucrose pentatallowate, sucrose trirapeate, sucrose tetrarapeate, sucrose pentarapeate, sucrose tristearate and sucrose pentastearate, and mixtures thereof. The compositions give improved hair conditioning benefits, especially to hair which has been damaged, e.g. through environmental exposure or harsh mechanical or chemical treatments such as heat styling, perming or bleaching.Type: GrantFiled: December 13, 2001Date of Patent: July 15, 2003Assignee: Unilever Home & Personal Care USA division of Conopco, Inc.Inventors: Colin Christopher David Giles, Frances Ann Ellis, Andrew Malcolm Murray, Matthew Leslie Pearce, Pamela Eileen Red

Patent number: 6440439Abstract: Hair treatment compositions are provided which have conditioning benefits and which contain a fatty acid polyester of a polyol selected from cyclic polyols, sugar derivatives and mixtures thereof, in which at least 50% by weight of the total fatty acid moieties of the polyester are C20 or higher unsaturated fatty acid moieties. Specific examples of suitable fatty acid polyesters are sucrose trierucate, sucrose pentaerucate, sucrose tetraerucate, sucrose trirapeate, sucrose tetrarapeate, and sucrose pentarapeate, and mixtures thereof. The compositions are typically in the form of shampoos or conditioners and give surprisingly improved overall conditioning, in particular hair softness.Type: GrantFiled: February 2, 2000Date of Patent: August 27, 2002Assignee: Unilever Home & Personal Care USA division of Conopco, Inc.Inventors: Colin Christopher David Giles, Frances Ann Ellis, Andrew Malcolm Murray, Matthew Leslie Pearce, Pamela Eileen Red
