Thickened hair colourant and bleaching compositions
View Patent ↗The present invention relates to hair colouring and hair bleaching compositions comprising a first component comprising at least one oxidizing agent and a C6 to C16 alkyl glucoside and a second component comprising an anionic surfactant and a fatty alcohol. The compositions surprisingly provide improved hair colourant and bleaching compositions which deliver lift, lightening and colour, whilst minimizing damage and which provide the required viscosity both pre and post mixing of the first and second components.
1. A hair colouring or bleaching composition comprising:
(1) a first component comprising an oxidizing agent, a C6 to C16 alkyl glucoside; and
(2) a second component comprising an anionic surfactant selected from the group consisting of a C8 to C30 alkyl phosphate, a C8 to C30 alkyl ether phosphate or mixtures thereof and, a C14 to C30 fatty alcohol and mixtures thereof.
2. A hair colouring or bleaching composition according to claim 1 , wherein said C6 to C16 alkyl glucoside is a C8 to C12 alkyl glucoside.
3. A hair colouring or bleaching composition according to claim 2 , wherein said alkyl glucoside is a C10 alkyl glucoside.
4. A hair colouring or bleaching composition according to claim 1 , wherein said composition comprises from about 0.1% to about 10% by weight of the C6 to C16 alkyl glucoside.
5. A hair colouring or bleaching composition according to claim 4 , comprising from about 0.5% to 5% by weight of the C6 to C16 alkyl glucoside.
6. A hair colouring or bleaching composition according to claim 1 , wherein said composition further comprises from about 0.1% to about 10% of an associative polymer.
7. A hair colouring or bleaching composition according to claim 1 , wherein said first component comprises from about 0.1% to about 10% of said oxidising agent and said second component comprises from about 0.1% to about 5% of said anionic surfactant and from about 2% to about 10% of said fatty alcohol.
8. A hair colouring or bleaching composition according to claim 1 , wherein said second component further comprises at least one source of alkalizing agent.
9. A hair colouring or bleaching composition according to claim 8 , wherein said alkalizing agent is selected from ammonium ions or ammonia.
10. A hair colouring or bleaching composition according to claim 1 , wherein said second component further comprises a non-ionic surfactant selected from polyoxyethylene C14 to C30 alkyl ethers having at least 25 ethylene oxide units.
11. A hair colouring or bleaching composition according to claim 10 , wherein said composition comprises from 0.1 to 5% by weight of said non-ionic surfactant.
12. A hair colouring composition according to claim 1 , wherein said composition comprises at least one oxidative dye precursor or at least one pre-formed dye, the at least one oxidative dye precursor or at least one pre-formed dye is comprised within the first component, the second components or may be comprised as a separate third component.
13. A method of treating hair comprising the steps of applying the composition 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.
