Patent number: 5260051Abstract: The invention relates to novel compositions, in particular personal product compositions containing phosphate ester surfactants in which a portion of the surfactant molecule has a so-called "benefit reagent" function. It is believed that this benefit reagent portion comes to play when the surfactant is metabolized or hydrolyzed.Type: GrantFiled: December 17, 1990Date of Patent: November 9, 1993Assignee: Lever Brothers Company, Division of Conopco, Inc.Inventor: Suk H. Cho
