Colouring composition
View Patent ↗The present invention is related to an aqueous colouring composition for keratin fibers especially human hair based on hair direct dyes and optionally oxidative dyes and comprising at least one arylated silicone.
1. An aqueous composition for colouring keratin fibres especially human hair comprising at least one direct dye selected from the group consisting of cationic, anionic and neutral nitro dyes and at least one arylated silicone selected from the group consisting of diphenylsiloxy phenyl trimethicone, tetramethyl tetraphenyl trisiloxane, triphenyl trimethicone, and tetramethyl tetraphenyl trisiloxane.
2. The aqueous composition according to claim 1 , wherein the direct dye is present at a concentration of 0.001 to 5% calculated to total composition.
3. The aqueous composition according to claim 1 comprising at least two arylated silicones.
4. The aqueous composition according to claim 1 wherein the arylated silicone is present at a concentration of 0.01 to 5% by weight calculated to total composition.
5. The aqueous composition according to claim 1 further comprising at least one surfactant selected from the group consisting of non-ionic, cationic, anionic and amphoteric surfactants.
6. The aqueous composition according to claim 1 further comprising at least one conditioning agent.
7. The aqueous composition according to claim 1 further comprising at least one oxidative dye precursor.
8. The aqueous composition according to claim 1 further comprising at least one oxidizing agent.
9. The aqueous composition according to claim 1 wherein the composition has a pH between 2 and 11.
10. A process for colouring hair wherein a composition according to claim 1 is applied onto hair and rinsed off from hair after a processing time of 5 to 45 min at a temperature of 20 to 45° C.
11. A process for colouring hair wherein a composition according to claim 1 is mixed first with a composition comprising at least one oxidizing agent and applied onto hair and rinsed off from hair after a processing time of 5 to 45 min at a temperature of 20 to 45° C.
12. A process for colouring hair wherein hair is bleached with a bleaching composition and after rinsing bleaching agent from hair a composition according to claim 1 is applied onto hair and rinsed off from hair after a processing time of 5 to 45 min at a temperature of 20 to 45° C.
13. A process for colouring and highlighting hair wherein a composition comprising at least one oxidizing agent is applied onto hair and left on the hair for 5 to 45 min and without rinsing off, the colouring agent according to claim 1 is applied onto hair in the second step and after processing additional 5 to 45 min the mixture is rinsed of from hair.
14. The aqueous composition according to claim 1 further comprising at least one fatty alcohol.
15. The aqueous composition according to claim 1 further comprising at least one organic solvent.
16. The aqueous composition according to claim 1 further comprising at least one UV filter.
17. The aqueous composition according to claim 7 further comprising at least one coupling agent.
