Abstract

A method of treating the hair including providing a concentrated hair care composition in an aerosol foam dispenser. The concentrated hair care composition includes from about 3% to about 18% of one or more oils, perfume, and less than 8% high melting point fatty compounds. The method also includes dispensing the concentrated hair care composition from the aerosol 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 aerosol foam dispenser.

Claims

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

a) providing a concentrated hair conditioner composition in an aerosol foam dispenser, wherein the concentrated hair conditioner composition comprises;

i) from about 3% to about 14% of soybean oil, by weight of the concentrated hair conditioner composition, wherein the particle size of the soybean is from about 1 nm to about 100 nm;

ii) less than 3% fatty alcohol, by weight of the concentrated hair conditioner composition, wherein the fatty alcohol is selected from the group consisting of cetyl alcohol, stearyl alcohol, behenyl alcohol, and mixtures thereof;

iii) from about 0.25% to about 5% cationic surfactant, by weight of the concentrated hair conditioner composition, wherein the cationic surfactant is selected from the group consisting of cetyl trimethyl ammonium chloride, behenyl trimethyl ammonium chloride, and combinations thereof;

iv) from about 5% to about 15% of a nonionic emulsifier wherein the nonionic emulsifier is polyoxyethylene (10) oleyl ether, by weight of the concentrated hair conditioner composition;

v) from about 2% to about 10% propellant, by weight of the concentrated hair conditioner composition;

vi) from about 0.5% to about 5% perfume, by weight of the concentrated hair conditioner composition; and

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

wherein the concentrated hair conditioner composition has a liquid phase viscosity of from about 1 centipoise to about 10,000 centipoise;

wherein the hair conditioner composition is silicone-free;

b) dispensing the concentrated hair conditioner composition from the aerosol foam dispenser as a 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 aerosol foam dispenser.

2. The method of claim 1, wherein the foam comprises an oil deposition purity of from about 40% to about 100% after applying the foam to the hair and rinsing the foam from the hair.

3. The method of claim 1, wherein the concentrated hair conditioner composition comprises from about 8% to about 14% of the soybean oil, by weight of the concentrated hair conditioner composition.

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

5. The method of claim 1, wherein the concentrated hair conditioner composition is substantially free of fatty alcohol, by weight of the concentrated hair conditioner composition.

6. The method of claim 1, wherein the concentrated hair conditioner composition comprises from about 2% to about 5% perfume, by weight of the concentrated hair conditioner composition.

7. 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 aerosol foam dispenser.

8. The method of claim 1, wherein the density of the foam is from about 0.035 g/cm³ to about 0.20 g/cm³.

9. The method of claim 1, wherein the hair conditioner composition has a liquid phase viscosity from about 5 centipoise to about 5000 centipoise.
