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;
wherein the composition is in a non-aerosol form chosen from a cream, a foam, a lotion, an emulsion, or a liquid;
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 said composition produces a film having a Young's modulus ranging from about 0.05 MPa to about 5 GPa, and a strain, under stress at 0.5 MPa, that ranges up to about 300%.

2. The hair styling composition of claim 1 , wherein latex polymers A and B, independently or together, are dispersed particles in an aqueous dispersion medium.

3. 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.

4. 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.

5. 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.

6. 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.

7. 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.

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

9. 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;
wherein the composition is in a non-aerosol form chosen from a cream, a foam, a lotion, an emulsion, or a liquid;
wherein the total combined amount of latex polymers A and B ranges from about 0.2% to about 20% 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.

10. The hair styling composition of claim 9 , wherein latex polymers A and B, independently or together, are dispersed particles in an aqueous dispersion medium.

11. The hair styling composition of claim 9 , 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.

12. The hair styling composition of claim 9 , 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.

13. The hair styling composition of claim 9 , 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.

14. The hair styling composition of claim 9 , wherein the weight ratio of latex polymers A:B ranges from about 1:5 to about 5:1.

15. The hair styling composition of claim 9 , wherein the weight ratio of latex polymers A:B ranges from about 1:3 to about 3:1.

16. The hair styling composition of claim 9 , wherein the weight ratio of latex polymers A:B is about 1:1.
