Abstract: The invention relates (I) to a process for dyeing keratin materials, in particular keratin fibres, preferably human keratin fibres such as the hair, using i) indigo-producing plant powder, ii) at least one alkaline agent as a post-treatment, preferably an alkali metal or alkaline-earth metal (bi) carbonate and iii) optionally a chemical oxidizing agent such as hydrogen peroxide or a hydrogen peroxide-generating system in co-treatment with i), and it being understood that the composition comprising the alkaline agent(s) is at a pH inclusively between 7.5 and 11.5; and (II) to the use iii) of alkaline agent(s) for fixing the blue colour of and/or for improving the dyeing kinetics of keratin materials dyed with indigo.

Abstract: The invention relates to a cosmetic composition comprising a blue dye powder containing an anthocyan, a metal ion and tannic acid and a cosmetic additive. The invention also relates to a process for making up keratin materials by applying the cosmetic composition to the keratin materials.

Abstract: The present invention relates generally to the field of colouring compositions. One aspect of the invention is a colouring composition having a blue colour. In particular, the present invention relates to a colouring composition having a blue colour wherein the composition comprises anthocyanins, metal ions, and at least one stabilizer. The metal ions are selected from Al(III), Ca(II), Cu(II), Fe(II), Fe(III), Mg(II), Mn(II), Zn(II) and combinations thereof; while the stabilizers are selected from tannic acid and phospholipids. The invention provides for example a composition comprising the colouring composition and also provides for the use of the colouring composition to colour a food, a nutritional formulation, a food supplement, a beverage, an ink or a pharmaceutical product. A further aspect of the invention is a method of preparing a blue colouring composition.

Abstract: The invention relates to a process for dyeing keratin fibers, in which said fibers are treated: ? with a composition (A) comprising i) one or more indole or indoline compounds; ii) one or more metal salts; iii) hydrogen peroxide or one or more systems that generate hydrogen peroxide; and then ? with a composition (B) comprising iv) one or more basifying agents. The invention also relates to a hair dyeing process for obtaining better colorations, which are more uniform, chromatic and remanent and which do not impair the cosmetic properties of keratin fibers.
