Abstract

Claims (28)

1. An oxidizing composition for the treatment of keratin fibers, comprising;

(a) at least one anionic associative copolymer,

(b) at least one anionic non associative copolymer;

(c) at least one peroxide agent;

(d) at least one persulfate agent;

(e) at least one alkalizing agent; and

(f) a carrier medium suitable for keratin fibers;

wherein the weight ratio of said anionic associative copolymer to said anionic non associative copolymer is from about 5:1 to about 1:5.

2. The composition according to claim 1 , wherein said anionic associative copolymer comprises a monomer having a carboxylic acid function and a monomer having an ester derived from a fatty alcohol and a carboxylic acid.

3. The composition according to claim 1 , wherein said anionic non associative copolymer comprises a monomer having a carboxylic function and a monomer having an ester derived from an alkoxylated fatty alcohol and carboxylic acid.

4. The composition according to claim 1 , wherein said composition comprises an anionic associative copolymer from about 0.01% to about 8% by weight of said composition.

5. The composition according to claim 4 , wherein said composition comprises an anionic associative copolymer from about 0.05% to about 5%, by weight of the composition.

6. The composition according to claim 4 , wherein said composition comprises an anionic associative copolymer from about 0.15% to about 2%, by weight of the composition.

7. The composition according to claim 1 , wherein said composition comprises an anionic non associative copolymer from about 0.01% to about 8% by weight of said composition.

8. The composition according to claim 7 , wherein said composition comprises an anionic non associative copolymer from about 0.05% to about 5%, by weight of the composition.

9. The composition according to claim 7 wherein said composition comprises an anionic non associative copolymer from about 0.15% to about 2%, by weight of the composition.

10. The composition according to claim 1 , wherein the peroxide agent is selected from the group consisting of hydrogen peroxide, urea peroxide, melamine peroxide, and combinations thereof.

11. The composition according to claim 1 , wherein said peroxide agent is present in said composition from about 0.6% to about 10.0% by weight of said composition.

12. The composition according to claim 1 , wherein said persulfate agent is present from about 2.0% to about 30.0% by weight of said composition.

13. The composition according to claim 1 , wherein said composition further comprises at least one cosmetic ingredient selected from the group consisting of dyes, chelants, hair care additives, paraffin oils, perfume oils and mixtures thereof.

14. A method for hair treatment comprising the steps of:

(i) providing a first mixture comprising at least one peroxide agent, at least one anionic associative copolymer, at least one anionic non associative copolymer, and a first carrier medium and;

(ii) providing a second mixture comprising at least one persulfate agent, at least one alkalizing agent, and a second carrier medium;

(iii) mixing the first mixture and the second mixture in order to obtain an oxidizing composition as defined in claim 1 ; and

(iv) applying said oxidizing composition onto keratin fibers.

15. An oxidizing composition kit comprising:

(i) a first separately packaged composition comprising at least one peroxide agent, at least one anionic associative copolymer, at least one anionic non associative copolymer and a first carrier medium; and

(ii) a second separately packaged composition comprising at least one persulfate agent, at least one alkalizing agent and a second carrier medium.
