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 silicones, perfume, an emulsifier system, 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 care composition in a dispenser, wherein the concentrated hair care composition comprises;

i) from about 2% to about 10% fatty alcohol by weight of the concentrated hair care composition, selected from the group consisting of cetyl alcohol, stearyl alcohol, behenyl alcohol, and mixtures thereof;

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

an emulsion comprising;

a) an amodimethicone comprising a particle size from about 8 nm to about 200 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;

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

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

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

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

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

2. The method of claim 1, wherein the particle size of the amodimethicone is from about 10 nm to about 100 nm.

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

5. The method of claim 1, wherein the concentrated hair care composition comprises from about 2% to about 12% of a nonionic emulsifier, by weight of the concentrated hair care composition.

6. The method of claim 1, wherein the concentrated hair care composition comprises an amodimethicone to fatty alcohol ratio of from about 40:

60 to about 70;

30.

7. 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.

8. The method of claim 1, wherein the concentrated hair care composition comprises from about 4% to about 8% fatty alcohols, by weight of the concentrated hair care composition.

9. The method of claim 1, wherein the concentrated hair care composition comprises from about 2.25% to 4% fatty alcohols, 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 6% perfume, by weight of the concentrated hair care composition.

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

12. The method of claim 1, wherein the concentrated hair care composition has a dosage weight of from about 2.5 g to about 5 g.

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

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