Abstract

A hair conditioning foamed mousse product is provided which is housed in a pressurized canister fitted with valve having total orifice of at least 0.0002 in² (0.13 mm²). The canister is filled with a cationic surfactant, a high molecular weight silicone, a low molecular weight silicone and a propellant. Advantageously the ratio of low to high molecular weight silicone ranges from 10:1 to 1:10. The low molecular weight silicone in amounts less than 1% counters the anti-foaming effect of the high molecular weight silicone thereby allowing formation of a stable light/airy foam. Also provided is a method for conditioning hair with mousse product applied to hair within a shower stall.

Claims

1. The hair conditioning mousse product comprising:

(i) a canister fitted with a spray nozzle and a valve of total orifice size greater than 0.0002 in² (0.13 mm²); and

(ii) a hair conditioning composition held within the canister and dispensible therefrom, the composition comprising;

(a) from about 0.01 to about 10% of a cationic surfactant by weight of the composition;

(b) from about 0.001 to about 2% of a high molecular weight silicone by weight of the composition;

(c) from about 0.001 to less than 1% of a low molecular silicone by weight of the composition;

(d) from about 0.5 to about 10% of a propellant by weight of the composition; and

wherein the low molecular weight to high molecular weight silicones are present in a weight ratio ranging from about 10;

1 to about 1;

10;

2. The product according to claim 1 wherein the low molecular weight silicone has a viscosity that is no higher than 100 cst (1×

10<sup>−

4</sup> m²/s) and is selected from cyclomethicone, phenyltrimethicone and linear dimethicone.

3. The product according to claim 1 wherein the low molecular weight silicone is decamethyl cyclopentasiloxane.

4. The product according to claim 1 wherein the low molecular weight silicone has a viscosity ranging from 0.65 to 100 cst (0.65×

10<sup>−

6</sup> to 1×

10<sup>−

4</sup> m²/s).

5. The article according to claim 1 wherein the ratio of low to high molecular weight silicone ranges from about 2:

1 to 1;

5.

6. The article according to claim 1 wherein the low molecular weight silicone is present at a concentration from about 0.05 to about 0.5% by weight of the composition.

7. The article according to claim 1 further comprising an oil soluble quaternary ammonium compound which is a mixture of a di-C₁₆ alkyl and di-C₁₈ alkyl quat present in a relative ratio of 5:

1 to 1;

5 and also in an amount from about 0.01 to about 5% by weight of the composition.

8. A method for conditioning hair comprising:

(A) providing a hair conditioning product comprising;

(i) a canister fitted with a spray nozzle and a valve of total orifice size greater than 0.0002 in² (0.13 mm²); and

(ii) a hair conditioning composition held within the canister and dispensible therefrom, the composition including;

(a) from about 0.01 to about 10% of a cationic surfactant by weight of the composition;

(b) from about 0.001 to about 2% of a high molecular weight silicone by weight of the composition;

(c) from about 0.001 to less than 1% of a low molecular silicone by weight of the composition;

(d) from about 0.5 to about 10% of a propellant by weight of the composition; and

wherein the low molecular weight to high molecular weight silicones are present in a weight ratio ranging from about 10;

1 to about 1;

10;

(B) placing a person intending to use the product in a shower stall having an overhead fixture for delivery of a water spray;

(C) dispensing foam mousse from the product and placing the foam mousse onto hair of the person; and

(D) rinsing with water from the fixture the foam mousse placed onto the hair.
