Thickened hair colourant and bleaching compositions
View Patent ↗The present invention relates to hair colouring and hair bleaching compositions comprising at least one oxidizing agent, a specified gel network thickener system comprising a specified tertiary component system, and a polysaccharide and a polyol. The compositions surprisingly provide hair colourant and bleaching compositions which deliver lightening and colour which are easy to manufacture and improve adhesion of the composition to the hair roots.
1. A hair colouring or bleaching composition comprising an oxidizing agent, a gel network thickening system comprising:
i) a first surfactant component selected from the group consisting of C14 to 30 alkyl phosphate, C14 to C30 alkyl ether phosphate and mixtures thereof;
ii) a second component selected from the group consisting of C14 to C30 fatty alcohols; and
iii) a third surfactant component selected from the group consisting of polyoxyethylene C14 to C30 alkyl ethers; wherein said composition comprises at least 1% of said first surfactant and at least 3% of the sum of said first surfactant component, second component and third surfactant component, and wherein said composition further comprises at least about 0.05% of a polysaccharide,
at least 3% of a polyol selected from the group consisting of propylene glycol, butoxydiglycol, ethoxydiglycol, hexylene glycol, dipropylene glycol, glycerol, polyglycerol, and mixtures thereof, and wherein said composition has an ionic strength of less than 0.75 mole/kg and a viscosity of from about 9 Pa·s to about 16 Pa·s.
2. A hair colouring or bleaching composition according to claim 1 , wherein said polysaccharide is selected from the group consisting of xanthan gum, succinoglycan and mixtures thereof.
3. A hair colouring or bleaching composition according to claim 1 , wherein said composition comprises from about 0.05 to about 0.125% of said polysaccharide.
4. A hair colouring or bleaching composition according to claim 1 , wherein said polyol is propylene glycol.
5. A hair colouring or bleaching composition according to claim 1 , comprising at least 3.5% of said polyol.
6. A hair colouring or bleaching composition according to claim 1 , comprising at least 4% of said polyol.
7. A hair colouring or bleaching composition according to claim 1 , wherein said ionic strength is from about 0.1 to less than about 0.75 mole/kg.
8. A hair colouring or bleaching composition according to claim 1 , wherein said ionic strength is from about 0.2 to about 0.6 mole/kg.
9. A hair colouring or beaching composition according to claim 1 , wherein said composition comprises from about 1 to about 3% of said first surfactant component, from about 2 to about 8% of said second component and from about 0.1 to about 5% of said third surfactant component.
10. A hair colouring or bleaching composition according to claim 1 , wherein said composition further comprises at least one source of alkalizing agent.
11. A hair colouring or bleaching composition according to claim 10 , wherein the at least one source of alkalizing agent is a source of ammonium ions or ammonia.
12. A hair colouring or bleaching composition according to claim 1 wherein said third surfactant is selected from polyoxyethylene C14 to C30 alkyl ethers having at least about 25 ethylene oxide units.
13. A hair colouring or bleaching composition according to claim 12 wherein said third surfactant is selected from polyoxyethylene C14 to C30 alkyl ethers having from about 100 to about 200 ethylene oxide units.
14. A hair colouring composition according to claim 1 , wherein said composition further comprises at least one dye component selected from an oxidative dye precursor or a pre-formed dye.
15. 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 about 2 to about 60 minutes and subsequently rinsing said composition from the hair.
