Abstract:
1. A method of manufacturing a hair conditioning composition, wherein the composition comprises a cationic selected from the group consisting of behenyl trimethyl ammonium chloride and stearyl trimethyl ammonium chloride surfactant, fatty alcohol selected from the group consisting of stearyl alcohol, cetyl alcohol, behenyl alcohol and mixtures thereof and an aqueous carrier; wherein a total amount of the cationic surfactant and the high melting point fatty compound is from about 7.0% to about 15% by weight of the composition; wherein the method comprises the steps: wherein the premix has a temperature of from about 65° C. to about 95° C. when mixing it with the aqueous carrier wherein the aqueous carrier has a temperature of from about 10° C. to about 52° C.; when mixing it with the premix wherein the temperature of the aqueous phase, when mixing it with the premix is at least about 5° C. lower than the temperature of the premix wherein the temperature of the aqueous carrier, when mixing it with the premix, is from about 2° C. to about 60° C. lower than the melting point of the high melting point fatty compounds; and wherein the premix and the aqueous carrier are mixed by a high shear homogenizer wherein the hair conditioning composition comprises less than 0.1% dialkyl cationic surfactants, by weight of the composition and wherein the oil phase is substantially free of water and wherein the premix is injected to a high shear field having an energy density of from about 1.0×10
