<p>The invention relates to novel 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 into play when the surfactant is metabolized or hydrolyzed following delivery to the skin. The surfactants are generally of the formula: <CHEM> 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. The surfactants have good surface active properties and are mild, making them useful in compositions for application to the human body.</p> |
