Abstract:
A method for enhancing the topical application of a benefit agent which comprises topically administering to a human or animal a micellar composition comprising, based upon the total weight of the composition:A. from about 1 percent to about 10 percent of a nonionic lipid selected from the group consisting of: i. glyceryl monoesters having a fatty acid chain containing from about 3 to about 50 carbon atoms; ii. glyceryl diesters having a fatty acid chain containing from about 5 carbon atoms to about 25 carbon atoms; iii. alkoxylated alcohols alkoxylated with ethylene oxide or propylene oxide; iv. alkoxylated alkyl phenols alkoxylated with ethylene oxide or propylene oxide; v. alkoxylated acids alkoxylated with ethylene oxide or propylene oxide; vi. alkoxylated amides alkoxylated with ethylene oxide or propylene oxide; vii. alkoxylated sugar derivatives alkoxylated with ethylene oxide or propylene oxide; viii. alkoxylated derivatives of natural oils or waxes alkoxylated with ethylene oxide or propylene oxide; ix. polyoxyethylene fatty ethers having a fatty acid chain containing from about 10 carbon atoms to about 18 carbon atoms; x. steroids; xi. fatty acid esters of alcohols where the fatty acid is straight or branched chain having from about 10 carbon atoms to about 20 carbon atoms and the alcohol is straight or branched chain having 1 to 10 carbon atoms; and xii. mixtures thereof; B. from about 74 percent to about 98 percent of a vehicle comprised of: 1) a first vehicle component comprised of water; and 2) a second vehicle component comprised of an alcohol, a polyol, or mixtures thereof; and C. an effective amount of the skin or hair benefit agent, wherein said micelle is comprised of said nonionic lipid and said second vehicle component.
