Abstract
The present invention relates to compounds and, more particularly, to a class of compounds having specific quaternized amine based upon a dimer acid amido amine linked to specific phosphate esters. Dimer acid is a C-36 diacid having a cyclic structure and two amine groups that allow for the synthesis of a high molecular weight material phospholipid composition which is 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.
