Abstract

Disclosed are hair styling compositions comprising at least two latex polymers, wherein at least one latex polymer is a film-forming polymer. The composition is capable of forming a film having certain properties on a substrate. Methods of styling the hair are also disclosed.

First claim

What is claimed is:

1. A method of styling the hair, said method comprising applying to the hair a composition comprising:
a) latex polymer A, wherein latex polymer A is Polyurethane-34, and
b) latex polymer B, wherein latex polymer B is Acrylates copolymer;
wherein the total combined amount of latex polymers A and B ranges from about 0.1% to about 30% by weight, relative to the weight of the composition; and
wherein the weight ratio of latex polymers A:B ranges from about 10:1 to about 1:10.

2. The method of claim 1 , further comprising a step of treating the hair with heat at a temperature ranging from about 25° C. to about 250° C. before, during, or after the application of said composition.

3. A method of styling the hair, said method comprising applying to the hair a composition comprising:
(1) an aqueous dispersion comprising:
(a) latex polymer A, wherein latex polymer A is Polyurethane-34; and
(b) latex polymer B, wherein latex polymer B is Acrylates copolymer; and

(2) at least one solvent;
wherein the total combined amount of latex polymers A and B ranges from about 0.1% to about 10% by weight, relative to the weight of the composition; and
wherein the weight ratio of latex polymers A:B ranges from about 10:1 to about 1:10.

4. The method of claim 3 , further comprising a step of treating the hair with heat at a temperature ranging from about 25° C. to about 250° C. before, during, or after the application of said composition.

5. The method according to claim 1 , wherein latex polymers A and B are, independently or together, dispersed particles in an aqueous dispersion medium.

6. The method according to claim 1 , wherein latex polymers A and B are present in a combined amount ranging from about 0.5% to about 10% by weight, relative to the weight of the composition.

7. The method according to claim 1 , wherein latex polymers A and B are present in individual amounts ranging from about 0.05% to about 10% by weight, relative to the weight of the composition.

8. The method according to claim 1 , wherein latex polymers A and B are present in individual amounts ranging from about 1% to about 15% by weight, relative to the weight of the composition.

9. The method according to claim 1 , wherein the weight ratio of latex polymers A:B ranges from about 1:5 to about 5:1.

10. The method according to claim 1 , wherein the film has a Young's modulus ranging from about 80 MPa to about 5 GPa and a strain, under stress at 0.5 MPa, ranging from about 0.01% to less than about 1%.

11. The method according to claim 10 , wherein the weight ratio of latex polymers A:B ranges from about 1:10 to about 1:1.

12. The method according to claim 1 , wherein the film has a Young's modulus ranging from about 5 MPa to about 100 MPa and a strain, under stress at 0.5 MPa, ranging from about 0.5% to less than about 20%.

13. The method according to claim 12 , wherein the weight ratio of latex polymers A:B ranges from about 3:1 to about 10:1.

14. The method according to claim 1 , wherein the film has a Young's modulus ranging from about 0.05 MPa to about 5 MPa and a strain, under stress at 0.5 MPa, ranging from about 10% to about 300%.

15. The method according to claim 1 , wherein the weight ratio of latex polymers A:B ranges from about 5:1 to about 10:1.

16. The method according to claim 3 , wherein latex polymers A and B are present in a combined amount ranging from about 0.5% to about 10% by weight, relative to the weight of the composition.

17. The method according to claim 3 , wherein latex polymers A and B are present in individual amounts ranging from about 0.05% to about 10% by weight, relative to the weight of the composition.

18. The method according to claim 3 , wherein latex polymers A and B are present in individual amounts ranging from about 1% to about 15% by weight, relative to the weight of the composition.

19. The method according to claim 3 , wherein the weight ratio of latex polymers A:B ranges from about 1:5 to about 5:1.

20. The method according to claim 3 , wherein the film has a Young's modulus ranging from about 80 MPa to about 5 GPa and a strain, under stress at 0.5 MPa, ranging from about 0.01% to less than about 1%.

21. The method according to claim 20 , wherein the weight ratio of latex polymers A:B ranges from about 1:10 to about 1:1.

22. The method according to claim 3 , wherein the film has a Young's modulus ranging from about 5 MPa to about 100 MPa and a strain, under stress at 0.5 MPa, ranging from about 0.5% to less than about 20%.
