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 one or more silicones, perfume, and less than 10% 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 0.40 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 care composition in an aerosol foam dispenser, wherein the concentrated hair care composition comprises;

i. from about 3% to about 25% of one or more silicones, by weight of the concentrated hair care composition, wherein the particle size of the one or more silicones is from about 1 nm to about 500 nm;

ii. less than 10% high melting point fatty compounds, by weight of the concentrated hair care composition;

iii. from about 1% to about 12% propellant, by weight of the concentrated hair care composition;

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

v. from about 0.01% to about 20% of a nonionic emulsifier, by weight of the concentrated hair care composition; and

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

wherein the concentrated hair care composition has a liquid phase viscosity of from about 1 centipoise to about 15,000 centipoise;

wherein the concentrated hair care composition has a silicone to high melting point fatty compound ratio of from about 100;

0 to about 50;

50; and

wherein the concentrated hair care composition has a silicone to perfume ratio of from about 98;

2 to about 50;

50;

b. dispensing the concentrated hair care 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 0.40 g/cm³ when dispensed from the aerosol foam dispenser.

2. The method of claim 1, wherein the concentrated hair care composition has a liquid phase viscosity of from about 1 centipoise to about 8,000 centipoise.

3. The method of claim 1, wherein the one or more silicones are selected from the group consisting of aminosilicones, pendant quaternary ammonium silicones, terminal quaternary ammonium silicones, amino polyalkylene oxide silicones, quaternary ammonium polyalkylene oxide silicones, amino morpholino silicones, and mixtures thereof.

4. The method of claim 1, wherein the concentrated hair care composition comprises from about 4% to about 20% of the one or more silicones, 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 the nonionic emulsifier, by weight of the concentrated hair care composition.

6. The method of claim 1, wherein the nonionic 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.

7. The method of claim 1, wherein the foam comprises a silicone deposition purity of from about 50% to about 100% after applying the foam to the hair and rinsing the foam from the hair.

8. The method of claim 1, wherein the particle size of the one or more silicones is from about 5 nm to about 300 nm.

9. The method of claim 1, wherein the particle size of the one or more silicones is from about 8 nm to about 200 nm.

10. The method of claim 1, wherein the particle size of the one or more silicones is from about 1 nm to about 100 nm.

11. The method of claim 1, wherein the concentrated hair care composition is in the form of a nanoemulsion.

12. The method of claim 1, wherein from about 25% to about 100% of the one or more silicones is in the form of a nanoemulsion, by weight of the concentrated hair care composition.

13. The method of claim 1, wherein the concentrated hair care composition comprises from about 5% to about 15% of one or more silicones, by weight of the concentrated hair care composition.

14. The method of claim 1, wherein the concentrated hair care composition comprises less than 6% high melting point fatty compounds, by weight of the concentrated hair care composition.

15. The method of claim 1, wherein the concentrated hair care composition comprises from about 1 to about 4% high melting point fatty compounds, by weight of the concentrated hair care composition, and wherein the silicone to high melting point fatty compound ratio is from about 100:

0 to about 50;

50.

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

17. 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.

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

19. The method of claim 1, wherein the viscosity is from about 700 centipoise to about 2,000 centipoise.

20. An aerosol foam dispenser comprising a concentrated hair care composition, the concentrated hair care composition comprising:

a. from about 3% to about 25% of a silicone, by weight of the concentrated hair care composition, wherein the particle size of the silicone is from about 1 nm to about 500 nm;

b. less than 10% high melting point fatty compounds, by weight of the concentrated hair care composition;

c. from about 1% to about 12% propellant, by weight of the concentrated hair care composition;

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

e. from about 0.01% to about 20% of a nonionic emulsifier;
