Oxidizing Composition

[0364] 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

Dyeing Protocol

[0365] The dye compositions A1 and A2 are each mixed with the oxidizing composition B in a 1+1 weight ratio.

[0366] 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.

[0367] After a leave-on time of 30 minutes on a hot plate at 27° C., the hair is rinsed, washed with L'Oréal Professionnel Pro Classics universal concentrated shampoo, diluted to 10%, and dried.

Results

[0368] 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.

[0369] 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.

[0370] The results are given in the table below.

TABLE-US-00003 TABLE 3 L* Process A1 + B (invention) 23.22 Process A2 + B (comparative) 31.71

[0371] The compositions according to the invention lead to lower values of L*, thus to a more powerful coloration, compared to the comparative composition.

[0373] The oxidizing composition B was prepared from the ingredients of which the contents are indicated in the table below:

TABLE-US-00005 TABLE 5 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

Dyeing Protocol

[0374] The dye compositions A3 and A4 are each mixed with the oxidizing composition B in a 1+1 weight ratio; the resulting mixtures having a pH of 10.0+/−0.2.

[0375] Each of the mixtures is applied to locks of hair containing 90% natural white (NW) hair and 90% permanent-waved natural white (PW) hair, in a proportion of 5 g of mixture per 1 g of hair.

[0376] After a leave-on time of 30 minutes on a hot plate at 27° C., the hair is rinsed, washed with L′Oréal Professionnel Pro Classics universal concentrated shampoo, diluted to 10%, and dried.

Results

[0377] 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.

[0378] 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.

[0379] The selectivity is represented by the colour difference ΔE between the locks of dyed natural (NW) hair and dyed permanent-waved (PW) hair, ΔE being obtained from the formula:

ΔE=√{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 ΔE, the lower the selectivity and the more uniform the colouration along the hair.

[0380] The results are given in the table below.

TABLE-US-00006 TABLE 6 L a b ΔE Process A3 + B NW 23.81 6.35 6.49 4.29 (invention) PW 21.34 4.8 3.34 Process A4 + B NW 27.54 4.13 10.45 6.33 (comparative) PW 23.59 3.22 5.59

[0381] The compositions according to the invention lead to lower values of L*, thus to a more powerful coloration, compared to the comparative composition.

[0382] The composition according to the invention A3 leads to a lower value of ΔE, and thus to better selectivity, compared to the comparative composition A4.
