Abstract

An aqueous hair conditioner composition comprising: a) a cationic conditioning surfactant, b) discrete, dispersed droplets comprising a water-insoluble conditioning oil and c) a block copolymer with a mean molecular weight of 1000 unified atomic mass units or more, comprising polyethyleneoxide and polypropyleneoxide blocks selected from the group consisting of (i) poloxamers according to formula (I), wherein the mean value of (y) is from 18 to 60 and the mean value (x) is from 7 to 140 such that the mean value of the ratio (x/y) is from 0.4 to 3.0 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.

An aqueous hair conditioner composition comprising:

a) a cationic conditioning surfactant,
b) discrete, dispersed droplets comprising a water-insoluble conditioning oil comprising silicone oil,
c) a block copolymer with a mean molecular weight of 1000 unified atomic mass units or more, comprising polyethyleneoxide and polypropyleneoxide blocks selected from the group consisting of (i) poloxamers according to formula I:
wherein the mean value of y is from 18 to 60 and the mean value x is from 7 to 140 such that the mean value of the ratio x/y is from 0.4 to 3.0
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, and
d) from 0.01 to 15% by weight of a fatty material selected from the group consisting of fatty alcohols, ethoxylated fatty alcohols, fatty acids and mixtures thereof;
and wherein:
the cationic conditioning surfactant is present in the aqueous hair conditioner composition in an amount of 0.05 to 5% by weight;
the water insoluble conditioning oil is present in the aqueous hair conditioner composition in an amount of 0.2 to 6% by weight and comprises silicone oil;
and
the block copolymer is present in the aqueous hair conditioner composition in an amount of from 0.01 to 0.7% by weight of the composition;
and
wherein the water-insoluble conditioning oil is dispersed into the aqueous hair conditioner composition as an oil-in-water emulsion formed by a process comprising steps of:
i) preparing a solution comprising water and the block copolymer,
ii) adding the water-insoluble conditioning oil to the solution, and
iii) forming the solution and the conditioning oil into the oil-in-water emulsion by high shear mixing;
and
wherein the aqueous hair conditioner composition is itself an oil-in-water emulsion.
