Abstract

A method of treating the hair including providing a concentrated hair care composition in a dispenser. The concentrated hair care composition includes one or more oils, perfume, and from about 2% to about 10% high melting point fatty compounds. The method also includes dispensing the concentrated hair care composition from the dispenser, applying the concentrated hair care composition the hair; and rinsing the concentrated hair care composition from the hair.

Claims

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

a) providing a concentrated hair conditioner composition in a 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, comprising a particle size of from about 5 nm to about 250 nm;

ii) from about 2% to about 6% fatty alcohol, by weight of the concentrated hair conditioner composition, selected from the group consisting of cetyl alcohol, stearyl alcohol, behenyl alcohol, and mixtures thereof;

iii) from about 0.5% to about 7% perfume, by weight of the concentrated hair conditioner composition;

iv) from about 5% to about 20% of a nonionic emulsifier, by weight of the concentrated hair conditioner composition, wherein the nonionic 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 0.25% to about 5% behenyltrimethylammonium methosulfate, by weight of the concentrated hair conditioner composition;

wherein the hair conditioner composition is silicone-free; and

b) dispensing the concentrated hair conditioner composition from the dispenser;

c) applying the concentrated hair conditioner composition to the hair; and

d) rinsing the concentrated hair conditioner composition from the hair.

2. The method of claim 1, wherein the soybean oil has a particle size of from about 10 nm to about 100 nm.

3. The method of claim 1, wherein the concentrated hair conditioner composition has a liquid phase viscosity of from about 300 centipoise to about 10,000 centipoise.

4. The method of claim 1, wherein the concentrated hair conditioner composition comprises from about 7.5% to about 12% of the nonionic emulsifier.

5. The method of claim 1, wherein the concentrated hair conditioner composition has a soybean oil to fatty alcohol weight ratio of from about 40:

60 to about 70;

30.

6. The method of claim 1, wherein the concentrated hair conditioner composition comprises an oil deposition purity of from about 30% to about 90% after applying the concentrated hair conditioner composition to the hair and rinsing the concentrated hair conditioner composition from the hair.

7. The method of claim 1, wherein the concentrated hair conditioner composition comprises from about 5% to about 10% of the soybean oil, by weight of the concentrated hair conditioner composition.

8. The method of claim 1, wherein the concentrated hair conditioner composition comprises from about 5% to about 14% of the soybean, by weight of the concentrated hair conditioner composition.

9. The method of claim 1, wherein the concentrated hair conditioner composition comprises from about 4% to about 6% of the soybean oil, by weight of the concentrated hair conditioner composition.

10. The method of claim 1, wherein the concentrated hair conditioner composition comprises from about 2.25% to 4% fatty alcohol.

11. The method of claim 1, wherein the concentrated hair conditioner composition comprises from about 1.5% to about 6% perfume, by weight of the concentrated hair conditioner composition.

12. 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.

13. The method of claim 1, wherein the concentrated hair conditioner composition has a dosage weight of from about 1 g to about 5 g.

14. The method of claim 1, wherein the concentrated hair conditioner composition has a density of about 1 g/cm³.
