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 hair styling composition comprising:
(a) latex polymer A having a Young's modulus ranging from about 0.1 MPa to about 10 MPa, and a strain, under stress at 0.5 MPa, of at least about 1%, wherein latex polymer A is Acrylates copolymer, Acrylates/Ethylhexyl Acrylate copolymer, Acrylates/VA copolymer, Polyurethane-34, Polyurethane-32, or Polyurethane-48;
(b) latex polymer B having a Young's modulus ranging from about 10 MPa to about 6 GPa, and a strain, under stress at 0.5 MPa, of less than about 5%, wherein latex polymer B is Acrylates copolymer, Polyacrylate-2 crosspolymer, Styrene/Acrylic copolymer, Polyurethane-35, Polyurethane-1, or Polycarbamyl Polyglycol Ester; and
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;
wherein the weight ratio of latex polymers A:B ranges from about 10:1 to about 1:10; and
wherein latex polymers A and B are dispersed particles in an aqueous dispersion medium.

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

3. The hair styling composition of claim 1 , wherein latex polymers A and B are present in a total combined amount ranging from about 1% to about 5% by weight, relative to the weight of the composition.

4. The hair styling composition of claim 1 , wherein latex polymers A and B are present in a total combined amount ranging from about 1% to about 3% by weight, relative to the weight of the composition.

5. The hair styling composition of 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.

6. The hair styling composition of 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.

7. The hair styling composition of claim 1 , wherein the weight ratio of latex polymers A:B ranges from about 1:5 to about 5:1.

8. The hair styling composition of claim 1 , wherein the weight ratio of latex polymers A:B ranges from about 1:3 to about 3:1.

9. The hair styling composition of claim 1 , wherein the weight ratio of latex polymers A:B ranges from about 1:2 to about 2:1.

10. The hair styling composition of claim 1 , wherein the weight ratio of latex polymers A:B is about 1:1.

11. The hair styling composition of claim 1 , wherein the weight ratio of latex polymers A:B is about 1:10 to about 1:1.

12. The hair styling composition of claim 1 , wherein the weight ratio of latex polymers A:B is about 3:1 to about 10:1.

13. The hair styling composition of claim 1 , wherein the weight ratio of latex polymers A:B is about 5:1 to about 10:1.

14. The hair styling composition of claim 1 , further comprising at least one solvent.

15. A method of styling the hair, said method comprising applying a composition comprising:
(a) latex polymer A having a Young's modulus ranging from about 0.1 MPa to about 10 MPa, and a strain, under stress at 0.5 MPa, of at least about 1%, wherein latex polymer A is Acrylates copolymer, Acrylates/Ethylhexyl Acrylate copolymer, Acrylates/VA copolymer, Polyurethane-34, Polyurethane-32, or Polyurethane-48;
(b) latex polymer B having a Young's modulus ranging from about 10 MPa to about 6 GPa, and a strain, under stress at 0.5 MPa, of less than about 5%, wherein latex polymer B is Acrylates copolymer, Polyacrylate-2 crosspolymer, Styrene/Acrylic copolymer, Polyurethane-35, Polyurethane-1, or Polycarbamyl Polyglycol Ester; and
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;
wherein the weight ratio of latex polymers A:B ranges from about 10:1 to about 1:10; and
wherein latex polymers A and B are dispersed particles in an aqueous dispersion medium.

16. The method of claim 15 , 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.
