Abstract

The invention concerns ready to use compositions for the reshaping and direct coloring of hair comprising glyoxylic acid, a glyoxyloyl amino acid or a mixture thereof and a direct dye, and a method for reshaping and coloring of hair by means of said compositions.

Claims

1. A ready-to-use composition for simultaneous reshaping and coloring of hair comprising at least one direct dye and a compound of formula (I) or the corresponding monohydrate of formula (II), respectively,

2. A composition according to claim 1 wherein the compound of formula I or II is selected from glyoxylic acid or a glyoxyloyl amino acid.

3. A composition according to claim 1 wherein the dyes are selected from anionic, neutral or cationic dyes.

4. A composition according to claim 3 wherein the dyes are anionic dyes.

5. A composition according to claim 4 wherein the dyes are selected from Acid Yellow 1, Acid Yellow 3, Acid Yellow 23, Acid Orange 7, Acid Red 33, Acid Red 40, Acid Red 52, Acid Red 92, Acid Violet 43, Acid Blue 7 and Acid Blue 9.

6. A composition according to claim 3 wherein the dyes are non ionic dyes.

7. A composition according to claim 6 wherein the dyes are selected from HC Yellow No. 7, 2-Amino-6-chloro-4-nitrophenol, 4-Nitro-o-phenylenediamine, 4-Amino-3-nitrophenol, HC Orange No. 1, HC Red No. 1, HC Red No. 3, HC Red No. 13, Disperse Violet 1, HC Yellow No.13 and Disperse Red 17.

8. A composition according to claim 3 wherein the dyes are cationic dyes.

9. A composition according to claim 8 wherein the dyes are selected from Basic Yellow 57, Basic Yellow 87, Basic Brown 16, Basic Brown 17, Basic Orange 31, Basic Red 51, Basic Red 76, HC Blue 15 and HC Blue 16, Basic blue 75 and Basic blue 124.

10. A composition according to claim 1 wherein the concentration of the dyes is between 0.01% and 5% by weight.

11. A composition according to claim 1 further comprising one or more auxiliary agents selected from anionic, neutral or cationic surfactants, anionic, neutral or cationic thickeners, organic solvents, silicones, cationic polymers.

12. A composition according to claim 1 characterized by a pH between 0.5 and 3.0.

13. A ready to use composition according to claim 1 obtained by mixing a first agent containing glyoxylic acid or a glyoxyloyl amino acid and a second agent containing at least one dye.

14. A kit for the preparation of a ready to use hair reshaping and coloring composition of claim 13 comprising a first agent containing glyoxylic acid or a glyoxyloyl amino acid and a second agent containing at least one dye.

15. A process for the reshaping and direct coloring of hair, comprising:

(i) contacting the hair with an aqueous ready-to-use composition of the invention containing glyoxylic acid or a glyoxyloyl amino acid and a dye, whereby the processing time is between 5 minutes and 45 minutes;

(ii) shaping the hair by means of heat and shaping aids.

16. A process according to claim 15 further comprising pre-washing the hair and rinsing and drying steps before or after the shaping step (ii).
