Abstract:
A shampoo or body wash composition comprising:(a) from about 1 weight percent to about 40 weight percent, based on the total weight of the composition of at least one anionic surfactant; (b) a water-dispersible conditioning complex, which does not dissolve in water, formed from at least (i) about 0.01 weight percent to about 4 weight percent, based on the total weight of the composition, of at least one tertiary alkyl ammidoamine, wherein at least one of the substituents of the tertiary amine is R1CONHR2â€”, wherein R1 is an alkyl group having from about 9 to about 21 carbon atoms, and R2 is an alkylene group having from 1 to about 8 carbon atoms; and (ii) at least one phosphate ester having a formula II wherein R6 is an alkylene group having from about 2 to about 4 carbon atoms, R7 is an alkyl group having from about 8 to 22 carbon atoms, n is a number ranging from 1 to about 30, R8 is hydrogen, an R7(OR6)nâ€” group, an alkyl group having from 1 to about 5 carbon atoms, a hydroxyalkyl group having from 1 to about 5 carbon atoms, an alkali metal, alkaline earth metal, diethanolamiine, or ammonium group, and wherein the amount of phosphate ester added to the composition is such that a solution consisting of water, the alkylamidoamine in the amount used in the shampoo or body wash composition, and the phosphate ester in the amount used in the shampoo or body wash composition, results in an aqueous pH ranging from about 4 to about 6, and wherein the molar ratio of the phosphate ester to the tertiary alkyl amidoamine is from about (1:1) to about (3:1) wherein the moles of phosphate ester used to form the conditioning complex is in an excess molar amount compared to the molar amount needed to neutralize the alkyl amidoamine; and(c) at least about 40 weight percent of water, wherein the composition has a pH of from about 4.0 to about 6.0.
