International ClassA61K 007/32Foreign Application Priority Data1991-11-12 GBAbstractNovel antiperspirant actives are amphiphilic materials which form, upon contact with perspiration, a water-insoluble liquid crystal phase of greater than one-dimensional periodicity, e.g. a cubic (three-dimensional periodicity) or hexagonal (two-dimensional periodicity) liquid crystal structure. Examples of such actives include lipids, surfactants, emulsifiers, polymer amphiphilic complexes and block copolymer surfactants which form the required liquid crystal phase upon contact with sweat. Preferably, antiperspirant compositions comprising the novel active(s) are free of conventional antiperspirant actives, especially aluminum and/or zirconium salts.Other References
