Abstract

A method of treating the hair including providing a concentrated hair care composition in a foam dispenser. The concentrated hair care composition includes one or more silicones, perfume, and less than 6% high melting point fatty compounds. The method also includes dispensing the concentrated hair care composition from the 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 foam dispenser. The one or more silicones form a silicone layer that has a Targeted Deposition Index of from about 0.8 to about 1.6.

Claims

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

a. providing a concentrated hair care composition in a 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;

ii. less than 5% high melting point fatty compounds, by weight of the concentrated hair care composition;

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

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

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

0 to about 50;

50;

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

2 to about 50;

50;

b. dispensing the concentrated hair care composition from the foam dispenser as a foam, wherein the foam has a density of from about 0.025 g/cm³ to about 0.40 g/cm³;

c. applying the foam to the hair, wherein the one or more silicones are deposited onto the hair when applying the foam to the hair; and

d. rinsing the foam from the hair;

wherein the one or more silicones forms a silicone layer on the hair; and

wherein the silicone layer has a Targeted Deposition Index of from about 0.8 to about 1.6.

2. ) The method of claim 1, wherein the Targeted Deposition Index is from about 0.9 to about 1.5.

3. ) The method of claim 1, wherein the Targeted Deposition Index is from about 1.0 to about 1.4.

4. ) The method of claim 1, wherein the Targeted Deposition Index is from about 1.05 to about 1.35.

5. ) The method of claim 1, wherein the Targeted Deposition Index is from about 1.10 to about 1.30.

6. ) The method of claim 1, wherein the Targeted Deposition Index is from about 0.85 to about 1.30.

7. ) The method of claim 1, wherein the Targeted Deposition Index is from about 0.9 to about 1.30.

8. ) The method of claim 1, wherein the Targeted Deposition Index is from about 0.95 to about 1.30.

9. ) The method of claim 1, wherein the Targeted Deposition Index is from about 1.0 to about 1.30.

10. ) The method of claim 1, wherein the Targeted Deposition Index is from about 1.10 to about 1.30.

11. ) The method of claim 1, wherein the Targeted Deposition Index is from about 1.15 to about 1.30.

12. ) The method of claim 1, wherein the concentrated hair care composition has a % Targeted Deposition of from about −

20% to about 50%.

13. ) The method of claim 1, wherein the concentrated hair care composition has a % Targeted Deposition of from about −

10% to about 40%.

14. ) The method of claim 1, wherein the concentrated hair care composition has a % Targeted Deposition of from about 10% to about 25%.

15. ) The method of claim 1, wherein the silicone to high melting point fatty compound weight ratio is from about 100:

0 to about 60;

40.

16. ) The method of claim 1, wherein the concentrated hair care composition has a silicone to (high melting point fatty compound plus cationic surfactant) weight ratio of from about 0.30 to about 10.

17. ) The method of claim 1, wherein the silicone is a polar functional silicone.

18. ) The method of claim 17, wherein the polar functional silicone is 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.

19. ) A foam dispenser comprising a concentrated hair care composition, 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;

ii. less than 5% high melting point fatty compounds, by weight of the concentrated hair care composition;

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

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

wherein the concentrated hair care composition is a rinse-off concentrated hair care composition;

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

0 to about 50;

50;

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

2 to about 50;

50;

wherein the foam has a density of from about 0.025 g/cm³ to about 0.40 g/cm³;

wherein the concentrated hair care composition deposits a silicone layer onto hair;

wherein the silicone layer has a Targeted Deposition Index of from about 0.8 to about 1.6.

20. ) The foam dispenser of claim 19, wherein the concentrated hair care composition has a % Targeted Deposition of from about −

20% to about 50%.
