| titleOfInvention | Hair colouring composition |
| abstract | The invention relates to a hair colour composition. The dyeing of hair using oxidative dyes (including polyphenols) oxidised by atmospheric oxygen (from the air or an air foam) and catalysed by the enzyme laccase is known. As laccase uses atmospheric oxygen to oxidise dyes, its efficiency is limited by both the availability of dissolved oxygen in the aqueous solution in which the enzyme and dyes are applied and also the diffusion of oxygen from air into the solution as the dissolved oxygen is depleted by the reaction. The inventors have observed that significant colour changes are observed over 30 minutes with selected polyphenols when treated with laccase in the presence of oxygen foams. Thus in a first aspect of the invention, a hair colour composition is provided, the hair colour composition comprising: (a) A polyphenol selected from the group consisting of catechin, epicatechin and a mixture thereof; (b) A laccase; (c) A surfactant; and (d) Pure oxygen or an oxygen generator; wherein the pure oxygen or oxygen generated by the oxygen generator is in the form of foam; and wherein the composition has a pH of 4.5 to 7.0, preferably less than or equal to 6.0. |
