Abstract

The present invention relates to a composition comprising at least one amylose-containing starch, and its use in extending or improving the color durability and stability of artificially colored hair. Such compositions may be applied either as a leave-on or as a rinse-off composition.

Claims (19)

1. A method of improving the color durability and stability of artificial color on hair comprising:

applying to artificially colored hair a composition comprising a pregelatinized amylose-containing starch; and

allowing the pregelatinized starch to dry prior to shampooing.

2. The method according to claim 1 wherein the pregelatinized amylose-containing starch is a modified starch.

3. The method according to claim 2 wherein the modified starch is at least cationically modified starch.

4. The method according to claim 2 wherein the modified starch is at least nonionically modified starch.

5. The method according to claim 1 wherein the pregelatinized amylose-containing starch is pregelatinized corn starch.

6. The method according to claim 1 wherein the pregelatinized amylose-containing starch is present in an amount of from about 0.25 to about 10% by weight, based on total weight of the composition.

7. The method according to claim 1 wherein the composition is a leave-in composition or a rinse-off composition.

8. The method according to claim 6 wherein the composition is a rinse-off composition and the rinse-off composition is at least a pre-shampoo treatment.

9. The method according to claim 1 wherein the composition is selected from mousse, gels, pomades, waxes, hair sprays, conditioners, and mixtures thereof.

10. The method according to claim 1 wherein the composition further comprises a hair fixative.

11. The method according to claim 1 wherein the pregelatinized amylose-containing starch is high amylose-containing starch.

12. The method according to claim 11 wherein the high amylose-containing starch comprises at least about 50% by weight, based on total weight of the starch, of amylose.

13. The method according to claim 1 wherein the composition further comprises a polyquaternium compound.

14. The method of claim 13 wherein the polyquaternium compound is cationic hydroxyethylcellulose.

15. The method of claim 13 wherein the polyquaternium compound is cationic acrylate.

16. The method according to claim 1 wherein the composition further comprises a blend of quaternium compounds.

17. The method according to claim 4 wherein the nonionically modified starch is hydroxypropyl starch.
