[0391] Oxidizing Composition

[0392] The oxidizing composition B was prepared from the ingredients of which the contents are indicated in the table below:

TABLE-US-00002 TABLE 2 Ingredients B SODIUM SALICYLATE 0.035 TETRASODIUM PYROPHOSPHATE 0.04 HYDROGEN PEROXIDE 6 CETEARYL ALCOHOL 2.28 CETEARETH-25 0.57 TETRASODIUM ETIDRONATE 0.06 TRIDECETH-2 CARBOXAMIDE MEA 0.85 GLYCEROL 0.5 PHOSPHORIC ACID qs pH 2.2 Water qs 100

[0393] Dyeing Protocol

[0394] The dyeing compositions A, A1 and A2 are each mixed with the oxidizing composition B in a 1+1 weight ratio.

[0395] Each of the mixtures is applied to locks of hair containing 90% natural white (NW) hair and sensitized (SA20) hair, in a proportion of 5 g of mixture per 1 g of hair.

[0396] 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 Classic universal concentrated shampoo, diluted to 10%, and dried.

[0397] Results

[0398] 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.

[0399] 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.

[0400] The selectivity is represented by the colour difference E between the locks of dyed natural (NW) hair and dyed sensitized (SA20) 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* represent the chromaticity of the dyed natural hair, and L.sub.0* represents the intensity and a.sub.0* and b.sub.0* represent the chromaticity of the dyed sensitized (SA20) hair. The lower the value of E, the lower the selectivity and the more uniform the colouration along the hair.

[0401] The following results are obtained.

TABLE-US-00003 TABLE 3 E A + B (invention) 1.36 A1 + B (comparative) 3.63 A2 + B (comparative) 5.07

[0402] Composition A according to the invention leads to a lower value of E, and thus to better selectivity, compared to the comparative compositions A1 and A2.

Example 2

[0403] Composition A according to the present invention and comparative composition A1 were prepared using the ingredients of which the contents are indicated in the table below:

[0404] Dyeing Protocol

[0405] The dyeing compositions A and A1 are each mixed with the oxidizing composition B in a 1+1 weight ratio. The pH of the obtained mixtures is 10,30,3.

[0406] Each of the mixtures is applied to locks of hair containing 90% natural white (NW) hair and permanent-waved hair (PW), in a proportion of 5 g of mixture per 1 g of hair.

[0407] 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 Classic universal concentrated shampoo, diluted to 10%, and dried.

[0408] Results

[0409] 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.

[0410] 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.

[0411] The selectivity is represented by the colour difference E between the locks of dyed natural (NW) hair and dyed permanent-waved (PW) 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* represent the chromaticity of the dyed natural hair, and L.sub.0* represents the intensity and a.sub.0* and b.sub.0* represent the chromaticity of the dyed permanent-waved hair. The lower the value of E, the lower the selectivity and the more uniform the colouration along the hair.

[0412] The following results are obtained.

TABLE-US-00005 TABLE 5 L a b E A + B NW 19.4 1.13 1.83 1.58 (invention) PW 18.17 0.74 0.92 A1 + B NW 22.47 1.24 2.38 4.01 (comparative) PW 19.29 0.58 0.02

[0413] Composition A according to the invention leads to a lower value of E, and thus to better selectivity, compared to comparative composition A1. The difference between the raw and the tips is lower with A+B than with A1+B: the coloration along the lock of hair is more homogenous with A+B.
