Patent abstract
The present invention relates to a novel class of polymeric compounds having specific quaternized amine based upon a dimer acid reacted with an alkanolamine to make an ester quaternary compound. 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 cationic compound 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. These materials are dimethylaminopropyl amine free, which is highly desirable in personal care applications.
