Description

EXAMPLES

[0602] In the examples that follow, all the amounts are given as weight percentage of active material (AM) relative to the total weight of the composition (unless stated otherwise).

[0603] Dyeing Composition

[0604] Composition A1 according to the present invention and comparative composition A2 were prepared using the ingredients of which the contents are indicated in the table below:

TABLE-US-00001 TABLE 1 A1 A2 (invention) (comparative) EDTA 0.2 0.2 MONOETHANOLAMINE 4.44 4.44 2-METHOXYMETHYL-P- 0.9 0.9 PHENYLENEDIAMINE PARAFFINUM LIQUIDUM 60 60 (liquid petroleum jelly) PEG-40 HYDROGENATED CASTOR OIL 1 1 SODIUM LAURYL SULFATE 1.24 1.24 ASCORBIC ACID 0.12 0.12 SODIUM METABISULFITE 0.22 0.22 COCO-GLUCOSIDE 3 3 HYDROXYBENZOMORPHOLINE 0.9 0.9 HYDROXYPROPYL GUAR 1 HYDROXYETHYLCELLULOSE 1 Water qs 100 qs 100

[0605] Oxidizing Composition

[0606] The oxidizing composition B was prepared from the ingredients of which the contents are indicated in the table below:

TABLE-US-00002 TABLE 2 B SODIUM SALICYLATE 0.035 TOCOPHEROL 0.1 TETRASODIUM PYROPHOSPHATE 0.04 HYDROGEN PEROXIDE 6 CETEARYL ALCOHOL 6 HEXADIMETHRINE CHLORIDE 0.15 POLYQUATERNIUM-6 0.2 PARAFFINUM LIQUIDUM 20 TETRASODIUM ETIDRONATE 0.06 PHOSPHORIC ACID qs pH 2.2 PEG-4 RAPESEEDAMIDE 1.2 GLYCERIN 0.5 STEARETH-20 5 Water qs 100

[0607] Dyeing Protocol

[0608] At the moment of use, the dye compositions A1 and A2 are each mixed with the oxidizing composition B in a 1+1 weight ratio.

[0609] Each of the mixtures is applied to locks of hair containing 90% natural white (NW) hair in a proportion of 3 g of mixture per 1 g of hair.

[0610] After a leave-on time of 30 minutes on a hot plate at 27 C., the hair is rinsed, washed with L'Oral Professionnel Pro Classics universal concentrated shampoo, diluted to 10%, and dried.

[0611] Results

[0612] The colouring of the hair is evaluated in the L*a*b* system, using a Konica Minolta CM-3600A spectrocolorimeter (illuminant D65, angle 10, specular component included) in the CIELab system.

[0613] In this system, L* represents the lightness. The lower the value of L*, the darker and more powerful the colouring obtained. The chromaticity is measured by the values a* and b*, a* representing the red/green axis and b* the yellow/blue axis.

[0614] The results are given in the table below:

TABLE-US-00003 TABLE 3 L* Process A1 + B (invention) 25.46 Process A2 + B (comparative) 27.68

[0615] The compositions according to the invention lead to a lower value of L*, thus to a better colour strength, compared to the comparative composition.
