EXAMPLES

[0355] 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).

[0356] Compositions A 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) ASCORBIC ACID 0.12 0.12 MONOETHANOLAMINE 4.74 4.74 SODIUM METABISULFITE 0.22 0.22 PARAFFINUM LIQUIDUM (liquid 60 60 petroleum jelly) 2-AMINO-3-HYDROXYPYRIDINE 0.1 0.1 HYDROXYBENZOMORPHOLINE 0.35 0.35 HYDROXYPROPYL GUAR 1 1 2-METHYL-5- 0.05 0.05 HYDROXYETHYLAMINOPHENOL SODIUM LAURYL SULFATE 1.24 1.24 HYDROXYETHYL-p- 0.8 0.8 PHENYLENEDIAMINE SULFATE COCO-GLUCOSIDE 3 3 PEG-40 HYDROGENATED CASTOR 1 1 OIL TETRASODIUM GLUTAMATE 0.1 DIACETATE (GLDA) Ethylenediaminetetraacetic acid 0.2 (EDTA) Water qs 100 qs 100

[0357] Oxidizing Composition

[0358] 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 HYDROGEN PEROXIDE 6 CETEARYL ALCOHOL 6 STEARETH-20 5 PEG-4 RAPESEEDAMIDE 1.2 TETRASODIUM ETIDRONATE 0.06 TETRASODIUM PYROPHOSPHATE 0.04 SODIUM SALICYLATE 0.035 PARAFFINUM LIQUIDUM (liquid 20 petroleum jelly) POLYQUATERNIUM-6 0.2 GLYCERIN 0.5 HEXADIMETHRINE CHLORIDE 0.15 TOCOPHEROL 0.1 PHOSPHORIC ACID qs pH 2.2 Water qs 100

[0359] Dyeing Protocol

[0360] The compositions A1 and A2 are each mixed with the oxidizing composition B in a 1+1 weight ratio.

[0361] Each of the mixtures is applied to locks of hair containing 90% natural white (NW) hair in a proportion of 5 g of mixture per 1 g of hair.

[0362] After a leave-on time of 30 minutes on a hot plate at 27 C., the hair is rinsed, washed with L'Oreal Professionnel Pro Classics universal concentrated shampoo, diluted to 10%, and dried.

[0363] Results

[0364] 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.

[0365] 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.

[0366] The build-up is represented by the colour difference E between the dyed and undyed locks of natural hair, E being obtained from the formula:

E={square root over ((L*L.sub.0 *).sup.2+(a*a.sub.0*).sup.2+(b*b.sub.0*).sup.2)}

in which L* represents the intensity and a* and b* the chromaticity of the dyed hair and L.sub.0* represents the intensity and a.sub.0* and b.sub.0* the chromaticity of the undyed hair. The greater the value of E, the better the colour build-up.

[0367] The results are summarized in the following table. The compositions are either prepared and applied without a storage period (TO), or are stored beforehand for 2 months at 45 C. before being used (2M45).

TABLE-US-00003 TABLE 3 L* a* b* E Undyed lock 66.44 0.33 14.46 A1 + B (invention) at t.sub.0 31.66 9.4 12.53 36 A1 + B (invention) after 30.42 9.1 11.41 37.21 storage for 2 months at 45 C. A2 + B (comparative) at t.sub.0 28.68 9.21 10.68 38.98 A2 + B (comparative) after 30.88 9.22 11.14 36.81 storage for 2 months at 45 C.

[0368] The composition according to the invention A1 is more stable over time compared to the comparative composition A2. Composition A1 makes it possible to obtain colourings which are equivalent in terms of build-up and strength based on compositions A1 used just after preparation or after 2 months of storage at 45 C., even with a content of GLDA which is 50% less than the content of EDTA of the comparative composition. In comparison, the colouring based on composition A2 after 2 months of storage at 45 C. shows a loss in strength and a significant loss in colour build-up compared to the colouring based on composition A2 used just after its preparation.
