Abstract
An aqueous hair conditioning composition comprising discrete, dispersed droplets of a hydrophobic conditioning oil with a mean droplet diameter (D3,2) of 4 micrometers or less, a cationic deposition polymer and a block copolymer of ethylene glycol and propylene glycol according to the Formula (I) with the mean value of y from 10 to 60 and the values of x and z both from 1 to 150, or a block copolymer according to Formula (II) wherein the mean value of a is 2 or more and the mean value of b is 2 or more.
Claims20
A rinse off, aqueous hair conditioner composition comprising:
- a) discrete, dispersed droplets of a hydrophobic silicone conditioning oil with a mean diameter (D3,2) 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.
