  • Patent number: 6645480
    Abstract: Hair conditioning formulations containing a particular combination of cationic surfactants, have improved hair care benefits while maintaining excellent in-use characteristics. The compositions contain a first cationic surfactant such as cetyl trimethyl ammonium chloride, stearyl trimethyl ammonium chloride and behenyl trimethyl ammonium chloride. A second hydrophilically substituted cationic surfactant such as cocamidopropyl-N-2-hydroxyethylcarbamoylmethyldimethylammonium chloride, and a lipid material such as cetyl alcohol. Although formulations of the invention are based principally on cationic surfactant, and generally contain no anionic or amphoteric surfactant, they provide an acceptable level of cleaning and lathering whilst still conveying the wet slippy feel desired by consumers in connection with conventional hair conditioners.
