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:
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.
本发明涉及新型
磷酸酯表面活性剂,其中表面活性剂分子的一部分具有所谓的 "益处试剂 "功能。据信,当表面活性剂在输送到皮肤后被代谢或
水解时,这部分益处试剂就会发挥作用。
表面活性剂一般为以下式子:
其中 R₁、R₂ 最好是 1 至 30 个碳原子的烷基,或 R₁ 氢,R₃ 最好是氢或第二个酯化分子。
这些表面活性剂具有良好的表面活性特性,而且性质温和,因此适用于用于人体的组合物。
