In a preferred embodiment, the fatty compound is selected from the group consisting of pure cetyl alcohol, pure stearyl alcohol, and pure behenyl alcohol. In another preferred embodiment, the hair conditioning composition is made by a method comprising the steps of mixing the amidoamine, the acid, and water at an elevated temperature, followed by addition of the fatty compound.</p> |
