Description

EXAMPLES

[0233] In the examples that follow, all the amounts are given, unless otherwise indicated, as mass percentages of active material (AM) relative to the total weight of the composition.

[0234] Compositions A (for dyeing) and B (for oxidizing) are prepared from the ingredients whose contents are indicated in the tables below (AM: active material):

TABLE-US-00001 TABLE 1 Composition A Fragrance 0.75 Ascorbic acid 0.4 Glycerol 5 EDTA 0.15 Thiolactic acid 0.4 2,5-Toluenediamine 1 Acrylates/beheneth-25 methacrylate copolymer 0.3 Ethanolamine 3.5 m-Aminophenol 0.5 2-Methylresorcinol 0.51 4-Amino-2-hydroxytoluene 0.024 Sodium laureth sulfate 2.1 Sodium sulfite 0.5 Carbomer 0.9 Hydroxybenzomorpholine 0.11 2-Methyl-5-hydroxyethylaminophenol 0.024 2,4-Diaminophenoxyethanol HCl 0.051 Water qs 100

TABLE-US-00002 TABLE 2 Composition B Sodium salicylate 0.035 Glycerol 0.5 Tetrasodium etidronate 0.06 Phosphoric acid qs pH 2.2 ? 0.2 Hydrogen peroxide 6 Tetrasodium pyrophosphate 0.04 Cetearyl alcohol 2.28 Ceteareth-25 0.57 Trideceth-2 carboxamide MEA 0.85 Water qs 100

[0235] Compositions A and B are each packaged in one compartment of a device 1 comprising two compartments 2, 3. Said device is configured to allow said compartments 2, 3 to be placed in communication and thus to enable the mixing of compositions A and B in one of the compartments.

[0236] In details, the two compartments 2 and 3 are moved relative to each other on a vertical axis X-X so as to release a passage between the two compartments 2, 3. Therefore, the two compartments 2, 3 are placed in fluid communication and composition B is mixed with composition A in compartment 2. Compositions A and B are mixed manually by shaking the device 1. After mixing, the ready-to-use composition obtained is applied to the keratin fibres via the dispensing orifice 7 of the device. The ready-to-use composition flows by gravity via the dispensing orifice 7.

[0237] The ratio of compositions A and B is 1:1.5.

[0238] The mixture leaves the device easily, with a good restitution, and spreads easily onto the head of hair. After a leave-on time of 5 minutes at room temperature, rinsing, washing with a standard shampoo and drying, the colouring obtained is powerful.
