Patent ID: 7611698

Claim:
A rinse off, aqueous hair conditioner composition comprising: a) discrete, dispersed droplets of a hydrophobic silicone conditioning oil with a mean diameter (D 3,2 ) of 4 micrometers or less, b) from 0.01 to 5% by weight of a cationic deposition polymer and c) 0.04% to 1% by weight of a block copolymer, comprising polyethyleneoxide and polypropyleneoxide blocks, selected from the group consisting of: (i) poloxamers according to formula I: wherein said poloxamers are selected from the group consisting of: (ia) poloxamers according to formula I wherein the mean value of y is from 10 to 60 and the mean values of x and z are both from 1 to 20, and (ib) poloxamers according to formula I wherein the mean value of y is 35 and the mean values of x and z are both 52, and (ii) poloxamines according to formula II: wherein the mean value of a is 2 or more and the mean value of b is 2 or more, d) from 5 to 20% by weight of the hair conditioning composition of anionic cleansing surfactant; e) co-surfactant; and f) optionally, emulsifier; wherein: (A) the rinse off aqueous hair conditioner composition is in the form of a shampoo, (B) the hydrophobic silicone conditioning oil is added to the composition as a pre-formed aqueous emulsion that includes the block copolymer, and (C) the total amount of surfactant, including any co-surfactant and emulsifier, is from 10 to 25 percent by weight of the composition.
