Abstract

A method of treating the hair including providing a concentrated hair care composition in a mechanical foam dispenser. The concentrated hair care composition includes one or more silicones, from about 1% to about 5% perfume, an emulsifier system, and is substantially free of high melting point fatty compounds. The method also includes dispensing the concentrated hair care composition from the mechanical foam dispenser as a dosage of foam; applying the foam to the hair; and rinsing the foam from the hair. The foam has a density of from about 0.025 g/cm³ to about 0.3 g/cm³ when dispensed from the mechanical foam dispenser.

Claims

1. A method of treating the hair, the method comprising:

a) providing a concentrated hair care composition in a mechanical foam dispenser, wherein the concentrated hair care composition comprises;

i) from about 1% to about 5% perfume, by weight of the concentrated hair care composition;

ii) an emulsion comprising;

a. an amodimethicone comprising a particle size from about 1 nm to about 100 nm;

b. from about 1% to about 10% of a first alcohol ethoxylate, by weight of the concentrated hair care composition, comprising from about 5 to about 9 moles of ethoxylate and an HLB value of from about 10.3 to about 13;

c. from about 0.5% to about 5% of a second alcohol ethoxylate, by weight of the concentrated hair care composition, comprising from about 2 to about 4.9 moles of ethoxylate and an HLB value of from about 8 to about 10.3;

 

wherein the concentrated hair care composition comprises from about 3% to about 25% of the amodimethicone, by weight of the concentrated hair care composition;

from about 60% to about 90% water, by weight of the concentrated hair care composition;

wherein the concentrated hair care composition is substantially free of fatty alcohol selected from the group consisting of cetyl alcohol, stearyl alcohol, behenyl alcohol, and mixtures thereof;

wherein the concentrated hair care composition has a liquid phase viscosity of from about 1 centipoise to about 80 centipoise;

b) dispensing the concentrated hair care composition from the mechanical foam dispenser as a dosage of foam;

c) applying the foam to the hair; and

d) rinsing the foam from the hair;

wherein the foam has a density of from about 0.025 g/cm³ to about 0.3 g/cm³ when dispensed from the mechanical foam dispenser.

2. The method of claim 1, wherein the concentrated hair care composition comprises from about 65% to about 87.5% water, by weight of the concentrated hair care composition.

3. The method of claim 1, wherein the particle size of the amodimethicone is from about 5 nm to about 80 nm.

4. The method of claim 1, wherein the particle size of the amodimethicone is from about 10 nm to about 60 nm.

5. The method of claim 1, wherein the concentrated hair care composition comprises from about 4% to about 20% of the amodimethicone, by weight of the concentrated hair care composition.

6. The method of claim 1, wherein the concentrated hair care composition comprises from about 5% to about 15% of the amodimethicone, by weight of the concentrated hair care composition.

7. The method of claim 1, wherein the concentrated hair care composition comprises from about 8% to about 15% of the amodimethicone, by weight of the concentrated hair care composition.

8. The method of claim 1, wherein the concentrated hair care composition comprises from about 8% to about 18% of the amodimethicone, by weight of the concentrated hair care composition.

9. The method of claim 1, wherein the concentrated hair care composition comprises 0% fatty alcohol, by weight of the concentrated hair care composition.

10. The method of claim 1, wherein the concentrated hair care composition comprises from about 1.5% to about 4.5% perfume, by weight of the concentrated hair care composition.

11. The method of claim 1, wherein the foam has a dosage weight of from about 1 g to about 5 g when dispensed from the mechanical foam dispenser.

12. The method of claim 1, wherein the density of the foam is from about 0.075 g/cm³ to about 0.175 g/cm^3.

13. The method of claim 1, wherein the viscosity is from about 5 centipoise to about 45 centipoise.

14. The method of claim 1, wherein the viscosity is from about 10 centipoise to about 40 centipoise.

15. The method of claim 1 wherein the emulsion is formed by phase inversion by composition.
