Abstract

A composition used for relaxing/straightening hair containing: (a) at least one hydroxide generator in an amount sufficient to relax/straighten keratin fibers; (b) at least one bioactive glass component; and (c) optionally, at least one complexing agent.

Claims

1. A composition comprising:

(a) at least one hydroxide generator in an amount sufficient to relax/straighten keratin fibers;

(b) at least one bioactive glass component; and

(c) optionally, at least one complexing agent.

2. The composition of claim 1 wherein the hydroxide generator is at least one monovalent metal hydroxide.

3. The composition of claim 2 wherein the hydroxide generator is present in an amount of from about 0.1 to about 3% by weight, based on the weight of the composition.

4. The composition of claim 1 wherein the hydroxide generator is at least one multivalent metal hydroxide.

5. The composition of claim 4 wherein the hydroxide generator is present in an amount of from about 0.1 to about 75% by weight, based on the weight of the composition.

6. The composition of claim 1 wherein the bioactive glass is present in an amount of from about 0.5 to about 50% by weight, based on the weight of the composition.

7. The composition of claim 1 wherein the complexing agent is present in the composition in an amount of from about 2 to about 50% by weight, based on the weight of the composition.

8. The composition of claim 1 wherein (b) is present in an amount of from about 4 to about 10% by weight and (c) is present in an amount of from about 5 to about 30% by weight, all weights based on the weight of the composition.

9. A process for treating hair comprising contacting the hair with a composition containing:

(a) at least one hydroxide generator in an amount sufficient to relax/straighten keratin fibers;

(b) at least one bioactive glass component; and

(c) optionally, at least one complexing agent.

10. The process of claim 9 wherein the hydroxide generator is at least one monovalent metal hydroxide.

11. The process of claim 10 wherein the hydroxide generator is present in an amount of from about 0.1 to about 3% by weight, based on the weight of the composition.

12. The process of claim 9 wherein the hydroxide generator is at least one multivalent metal hydroxide.

13. The process of claim 12 wherein the hydroxide generator is present in an amount of from about 0.1 to about 75% by weight, based on the weight of the composition.

14. The process of claim 9 wherein the bioactive glass is present in an amount of from about 0.5 to about 50% by weight, based on the weight of the composition.

15. The process of claim 9 wherein the complexing agent is present in the composition in an amount of up from about 2 to about 50% by weight, based on the weight of the composition.

16. The process of claim 9 wherein the keratin fibers are contacted with the composition at a pH of about 11.

17. A multicomponent kit for relaxing/straightening keratin fibers comprising:

(a) at least one compartment containing at least one hydroxide generator in an amount sufficient to relax/straighten keratin fibers; and

(b) at least one compartment containing at least one bioactive glass component and, optionally, at least one complexing agent.
