Patent

CA 2057709

The invention relates to compositions for application to the human body which incorporate a phosphate ester surfactant in which a portion of the surfactant molecule has a so-called "benefit reagent" function. It is believed that this benefit reagent-portion comes into play when the surfactant is metabolized or hydrolyzed following delivery to the skin. The surfactants are generally of the formula: Image wherein R1, R2 are preferably alkyl of 1 to 30 carbon atoms, or for R1 hydrogen, R3 is preferably hydrogen or a second esterifying moiety.
