This application is directed to hair and skin conditioning compositions which contain specific polyoxyalkylene substituted alkylene diamines. The polyoxyalkylene substituted alkylene diamines function as conditioning agents on hair and skin via cloud point deposition. The polyoxyalkylene substituted alkylene diamines in addition to functioning as conditioning agents on skin and hair by themselves also function to enhance deposition of lipophilic benefit agents such as for example fatty alcohols, esters of fatty acids, hydrophobic vitamin or vitamin complexes, natural or synthetic triglycerides including glyceryl esters and derivative, pearlescent waxes, hydrocarbon oils, siloxanes of silicones, perfume oils, super-fatting agents, water insoluble or slightly soluble organic sunscreens, micronized sunscreens, plant extracts, essential oils and hydrophobically modified pigments.
