Abstract

A mousse-forming cleansing shampoo composition having improved conditioning performance comprising:

(A) a foamable concentrate comprising:

(i) at least one surfactant;

(ii) emulsified particles of a conditioning agent having a particle size of ≦1 micron;

(iii) a deposition polymer for the emulsified particles;

(iv) an aqueous carrier; and

(B) an aerosol propellant.

Claims

1. A mousse-forming cleansing shampoo composition having improved conditioning performance comprising:

(A) a foamable concentrate comprising;

(i) at least one surfactant;

(ii) emulsified particles of a conditioning agent having a particle size of ≦

1 micron;

(iii) a deposition polymer for the emulsified particles;

(iv) an aqueous carrier; and

(B) an aerosol propellant.

2. A composition according to

claim 1

, in which the foamable concentrate is substantially free of crystalline suspending agents.

3. A composition according to

claim 1

or

claim 2

, in which the foamable concentrate further comprises a rheology modifier selected from the group consisting of polyethylene glycol (PEG), polypropylene glycol (PPG), sodium xylene sulphonate, sodium toluene sulphonate and urea.

4. A composition according to any preceding claim, in which the conditioning agent is pre-microemulsified dimethiconol.

5. A composition according to any of

claims 1

to

3

, in which the conditioning agent is a cross-linked silicone gum or a per-alk(en)yl hydrocarbon material.

6. A composition according to any preceding claim, in which the total amount of surfactant (including that used as emulsifier for the microemulsified particles of high viscosity silicone) is from 10% to 25% by weight of the foamable concentrate.

7. A composition according to any preceding claim, in which the deposition polymer is selected from the group consisting of cationic polyacrylamides and cationic guar derivatives.

8. A composition according to any preceding claim, in which the propellant gas is selected from the group consisting of dimethyl ether, propane, n-butane, isobutane and mixtures thereof.
