The use of a phosphate ester based upon a fatty alcohol or fatty alcohol alkoxylate as the material used to prepare a phospholipid results in heretofore-unknown compounds. The products are very good wetting agents, have improved hydrolytic stability, are extremely substantitive to human skin and are well tolerated by human tissue making them suitable for use preparation of barrier products for personal care applications. In short they are ideal surfactants for use in many personal care applications.Field of SearchNitrogen containing (e.g., cephalins, lecithins, etc.) |
