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

i) from about 3% to about 25% of one or more silicones, by weight of the concentrated hair care composition;

ii) from about 2% to about 10% high melting point fatty compounds, by weight of the concentrated hair care composition;

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

iv) an emulsifier system comprising;

a) from about 1% to about 10% of one or more Type I emulsifiers by weight of the concentrated hair care composition, the one or more Type I emulsifiers having from about 5 to about 9 moles of ethoxylate, the one or more Type I emulsifiers having an HLB value of from about 10.3 to about 13;

b) from about 0.5% to about 5% of one or more Type II emulsifiers by weight of the concentrated hair care composition, the one or more Type II emulsifiers having from about 2 to about 4.9 moles of ethoxylate, the one or more Type II emulsifiers having an HLB value of from about 8 to about 10.3; and

v) 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 200 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 80;

20 to about 30;

70, by weight of the silicone and by weight of the high melting point fatty compound; and

wherein the concentrated hair care composition has a silicone to perfume ratio of from about 95;

5 to about 50;

50, by weight of the silicone and by weight of the perfume;

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 one or more silicones has a particle size of from about 1 nm to about 500 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 one or more silicones are selected from aminosilicones, pendant quaternary ammonium silicones, terminal quaternary ammonium silicones, amino polyalkylene oxide silicones, quaternary ammonium polyalkylene oxide silicones, amino morpholino silicones, and mixtures thereof.

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

6. ) 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.

7. ) The method of claim 1, wherein the silicone is an aminosilicone comprising from about 0.7% to about 1.3% nitrogen content.

8. ) The method of claim 1, wherein the concentrated hair care composition has a silicone to high melting point fatty compound ratio of from about 40:

60 to about 70;

30.

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

10. ) The method of claim 1, wherein the concentrated hair care composition is a nanoemulsion.

11. ) 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.

12. ) The method of claim 1, wherein the concentrated hair care composition comprises a silicone deposition purity of from about 30% to about 90% after applying the concentrated hair care composition to the hair and rinsing the concentrated hair care composition from the hair.

13. ) The method of claim 1, wherein the concentrated hair care composition comprises from about 5% to about 15% of the 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 from about 4% to about 8% 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 2.25% to 4% high melting point fatty compounds, by weight of the concentrated hair care composition, and the silicone to high melting point fatty compound ratio is from about 50:

50 to about 80;

20.

16. ) 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.
