Abstract

The present invention relates to a hair colouring and/or bleaching composition comprising at least a first aqueous component (i) and a second aqueous component (ii) being mixed prior to application onto hair, wherein the first aqueous component (i) comprises, in a cosmetically acceptable carrier one or more oxidizing agent(s), and the second aqueous component (ii) comprises, in a cosmetically acceptable carrier, one or more alkalizing agent(s) selected from the group consisting of ammonia, its salts and mixtures thereof wherein the first component (i) or the second component (ii) or both comprise at least a first and a second malodor suppressant and optionally one or more further malodor suppressants, or the first component (i) comprises at least a first malodor suppressant and the second component (ii) comprises at least a second malodor suppressant, the first and the second malodor suppressant and any further malodor suppressant forming a malodor suppressant system in the hair colouring and/or bleaching composition, and each of the first and second malodor suppressants being a compound having a distribution coefficient log P of 2 or more and a molecular weight of between 100 and 400. The invention further relates to a hair colouring or bleaching kit comprising an individually packaged first and second aqueous component, a method of treating hair, a method of sequential oxidative hair colouring or hair bleaching and the use of at least a first and a second malodor suppressant as a malodor suppressant system in a composition for the treatment of hair.

First claim

What is claimed is:

1. A hair coloring and/or bleaching composition comprising at least a first aqueous component (i) and a second aqueous component (ii) being mixed prior to application onto hair, wherein:
the first aqueous component (i) comprises, in a cosmetically acceptable carrier: one or more oxidizing agent(s), one or more fatty alcohols and a polyoxyethylene C12-C30 alkyl ether and
the second aqueous component (ii) comprises, in a cosmetically acceptable carrier: one or more alkalizing agent(s) selected from the group consisting of ammonia, its salts and mixtures thereof, one or more fatty alcohols and a polyoxyethylene C12-C30 alkyl ether,
and optionally one or more oxidative dyes or one or more direct dyes or a mixture of one or more oxidative dyes and one or more direct dyes,

wherein the second aqueous component (ii) comprises a mixture of a first and a second malodor suppressant, the first and the second malodor suppressant forming a malodor suppressant system in the hair coloring and/or bleaching composition,
wherein the mixture of first malodor suppressant and second malodor suppressant is equal weight percentages of isopropyl myristate and Galaxolide at a mixture concentration in the second aqueous component (ii) to provide a concentration of the mixture of isopropyl myristate and Galaxolide in the mixture of the first aqueous component (i) and the second aqueous component (ii) of to about 0.7 wt %; and,
wherein a mixture of the first and second aqueous components exhibits a decrease of the amount of gaseous ammonia released relative to the combination of first and second aqueous components without the first and second malodor suppressants.

2. A hair coloring and/or bleaching composition according to claim 1 wherein the density of the malodor suppressant system present in the mixture of components (i) and (ii) divided by the density of the mixture of components (i) and (ii) without the malodor suppressant system is 1.1 or less.

3. A hair coloring and/or bleaching composition according to claim 1 wherein the first and second malodor suppressant form a solution upon mixing.

4. A hair coloring or bleaching composition according to claim 1 , wherein said composition after mixing components (i) and (ii) has a viscosity of from 1 to 2000 cPs.

5. A hair coloring or bleaching composition according to claim 1 , wherein said composition after mixing components (i) and (ii) has a viscosity of from 100 to 1500 cPs.

6. A hair coloring or bleaching composition according to claim 1 , wherein said composition after mixing components (i) and (ii) has a viscosity of from 200 to 1000 cPs.

7. A hair coloring or bleaching kit comprising
An individually packaged first aqueous component (i) comprising, in a cosmetically acceptable carrier one or more oxidizing agent(s), one or more fatty alcohols and a polyoxyethylene C12-C30 alkyl ether and
An individually packaged second aqueous component (ii) comprising in a cosmetically acceptable carrier one or more alkalizing agent(s) selected from the group consisting of ammonia, its salts and mixtures thereof, one or more fatty alcohols and a polyoxyethylene C12-C30 alkyl ether,
wherein the second aqueous component (ii) comprises a mixture of a first malodor suppressant and a second malodor suppressant, the first and the second malodor suppressant forming a malodor suppressant system in the hair coloring and/or bleaching composition,
wherein the mixture of first malodor suppressant and second malodor suppressant is equal weight percentages of isopropyl myristate and Galaxolide at a mixture concentration in the second aqueous component (ii) to provide a concentration of the mixture of isopropyl myristate and Galaxolide in the mixture of the first aqueous component (i) and the second aqueous component (ii) of to about 0.7 wt %; and,
wherein a mixture of the first and aqueous components exhibits a decrease of the amount of gaseous ammonia released relative to the combination of first and second aqueous components without the first and second malodor suppressants.

8. A method of treating hair comprising the steps of applying a composition after mixing according to claim 1 to the hair, leaving said composition on the hair for from 2 to 60 minutes and subsequently rinsing said composition from the hair.

9. A method according to claim 8 wherein said composition is retained on the hair for a time period of less than 50 minutes.

10. A method of sequential oxidative hair coloring or hair bleaching comprising the steps of at least two sequential oxidative hair color or hair bleaching treatments, wherein the time period between each treatment is from 1 day to 60 days, and wherein each treatment comprises the steps of providing a composition according to claim 1 , applying said composition to the hair and retaining said composition on the hair for a time period of less than 50 minutes and subsequently rinsing said composition from the hair.
