Abstract

Disclosed is a hair conditioning composition comprising: (a) a cationic surfactant being behenyltrimethylammonium methosulfate; (b) a high melting point fatty compound; and (c) an aqueous carrier; wherein the composition has a yield point of at least 15 Pa, and the yield point meeting the following mathematical expression: Y≧3.57 X²−44.4 X+151, wherein Y is yield point of the composition, X is a total amount (percentage by weigh of the composition) of the cationic surfactant and the high melting point fatty compound; and wherein the composition is substantially free of thickening polymers. The composition of the present invention effectively delivers conditioning benefits to hair.

Claims
