  • Patent number: 4940576
    Abstract: The invention relates to an aqueous clear single-phase liquid hair rinse conditioner. On dilution of the conditioner during use there is deposited on the hair a lyotropic liquid crystal phase formed by interaction between an ionised polymer and an ionic surfactant of opposite charge. There is also present in the composition a clarifying agent in order to maintain the composition in the form of a clear single-phase solution prior to dilution. The polymer-surfactant complex in the form of a liquid crystal phase deposited from the hair conditioner of the invention is more effective to improve the ease of wet combing of the hair than a complex not in the form of a liquid crystal.
