Abstract

Present invention relates to an aqueous oxidizing composition comprising at least one oxidizing, at least one alkyl or alkanol amine, urea, at least one carbonate salt and at least one natural triglyceride. Composition comprises furthermore hair dyes.

First claim

The invention claimed is:

1. An aqueous composition for hair comprising at least one oxidizing agent, at least one alkyl or alkanol amine, urea, at least one carbonate salt and at least one natural triglyceride.

2. The composition according to claim 1 wherein the at least one oxidizing agent is hydrogen peroxide.

3. The composition according to claim 1 wherein the at least one alkyl or alkanolamine is selected from compounds according to general structure
R 1 R 2 R 3 N

wherein R 1 , R 2 and R 3 are same or different H, C1-C6 alkyl, C1-C6 monohydroxyalkyl or C2-C6 polyhydroxyalkyl with the condition that at least one of R 1 , R 2 and R 3 is an alkyl or mono or polyhydroxyalkyl.

4. The composition according to claim 1 wherein the at least one alkyl or alkanol amine is present at a concentration of 1 to 35% by weight calculated to the total composition.

5. The composition according to claim 1 wherein the at least one alkyl or alkanolamine is monoethanolamine.

6. The composition according to claim 1 wherein the urea is present at a concentration 1 to 5% by weight, calculated to the total composition.

7. The composition according to claim 1 wherein the at least one carbonate salt is selected from sodium carbonate, sodium bicarbonate, ammonium carbonate, ammonium bicarbonate, guanidine carbonate and guanidine bicarbonate and their mixtures.

8. The composition according to claim 7 wherein the at least one carbonate salt is sodium carbonate.

9. The composition according to claim 1 wherein the carbonate salt is present at a concentration of 0.2 to 10% by weight calculated to the total composition.

10. The composition according to claim 1 wherein the urea and the at least one alkyl or alkanol amine are present at a weight ratio of 1.5 and higher.

11. The composition according to claim 1 wherein the at least one natural triglyceride is selected from argan oil, shea butter oil, karite oil, olive oil, almond oil, avocado oil, ricinus oil, coconut oil, palm oil, sesame oil, peanut oil, sunflower oil, peach kernel oil, wheat germ oil, macadamia nut oil, macadamia oil, night primrose oil, jojoba oil, castor oil, soya oil, lanolin, passiflora oil, black cumin oil, borage oils, grapeseed oil, hempseed oil, kukui nut oil, and rosehip oil and is present in the concentration range between 0.1 and 25% by weight calculated to total composition.

12. The composition according to claim 1 wherein the composition is free of ammonia.

13. The composition according to claim 1 further comprising at least one hair dye selected from direct and oxidative dyes.

14. Method of treating hair wherein an aqueous composition comprising applying a composition according to claim 1 onto hair and after processing 1 to 45 min rinsed off from hair.

15. Kit for hair characterized in that it comprises two or more compositions wherein the first composition is an aqueous composition comprising at least one alkyl or alkanol amine, urea, at least one carbonate salt and at least one natural trigylceride and the second composition comprising at least one oxidizing agent.
