Abstract

A method of treating the hair including providing a pre-aerated concentrated hair care composition. The pre-aerated concentrated hair care composition includes one or more silicones, perfume, and from about 2% to about 10% high melting point fatty compounds. The method also includes applying the pre-aerated concentrated hair care composition the hair; and rinsing the pre-aerated concentrated hair care composition from the hair. The pre-aerated concentrated hair care composition has a density of from about 0.15 g/cm³ to about 0.75 g/cm³ when dispensed from the aerosol foam dispenser.

Claims

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

a. providing a pre-aerated concentrated hair care composition, wherein the pre-aerated concentrated hair care composition comprises;

i. from about 8% to about 18%, by weight, of an Amodimethicone/Morpholinomethyl Silsesquioxane Copolymer;

ii. from about 4% to about 12%, by weight, of a fatty alcohol, wherein the fatty alcohol is a mixture of cetyl alcohol and stearyl alcohol;

iii. from about 2% to about 5%, by weight, of a perfume; and

iv. from about 50% to about 90%, by weight, water;

v. from about 0.25% to about 5% by weight of behentrimonium methosulfate wherein the pre-aerated concentrated hair care composition has a silicone to fatty alcohol ratio of from about 40;

60 to about 70;

30; and

b. applying the pre-aerated concentrated hair care composition to the hair; and

c. rinsing the pre-aerated concentrated hair care composition from the hair;

wherein the pre-aerated concentrated hair care composition is a nanoemulsion.

2. The method of claim 1, wherein the concentrated hair care composition comprises from about 55% to about 85% water, by weight of the pre-aerated concentrated hair care composition.

3. The method of claim 1 further comprising from about 2% to about 12% of a nonionic emulsifier, by weight of the pre-aerated concentrated hair care composition.

4. The method of claim 3 wherein the emulsifier is a condensation product of an aliphatic alcohol having from about 8 to about 18 carbons, in either straight chain or branched chain configuration, with from about 2 to about 35 moles of ethylene oxide.

5. The method of claim 1, wherein the pre-aerated concentrated hair care composition has a dosage weight of from about 2 g to about 7 g.

6. The method of claim 1, wherein the density of the pre-aerated concentrated hair care composition is from about 0.2 g/cm³ to about 0.7 g/cm³.
