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 oils, from about 1% to about 5% perfume, and has 0% 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 conditioner composition in a mechanical foam dispenser, wherein the concentrated hair conditioner composition comprises;

i) from about 4% to about 15% of soybean oil, by weight of the concentrated hair conditioner composition, wherein the particle size of the soybean is from about 12 nm to about 50 nm;

ii) 0% fatty alcohol selected from the group consisting of cetyl alcohol, stearyl alcohol, behenyl alcohol, and mixtures thereof;

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

iv) from about 5% to about 20% of a nonionic emulsifier wherein the nonionic emulsifier is polyoxyethylene (10) oleyl ether; and

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

vi) from about 0.5% to about 4% cetyl trimethyl ammonium chloride;

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

wherein the hair conditioner composition is silicone-free;

b) dispensing the concentrated hair conditioner 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 foam comprises a oil deposition purity of from about 90% to about 100% after applying the foam to the hair and rinsing the foam from the hair.

3. The method of claim 1 comprising from about 5% to about 15% of a nonionic emulsifier.

4. The method of claim 1, wherein the concentrated hair conditioner composition comprises from about 8% to about 18% of the soybean oil, by weight of the concentrated hair conditioner composition.

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

6. 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.

7. The method of claim 1, wherein the density of the foam is from about 0.035 g/cm³ to about 0.25 g/cm³.

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

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