[0214] Method for Dyeing Keratin Fibres

[0215] A composition (M) for the dyeing of keratin fibres is prepared in a bowl according to the following stages:

[0216] (1) 6 g of dyeing composition according to Table 6 above, 3.48 g of dyeing composition according Table 8 above, 1.32 g of dyeing composition according to Table 7 above, 1.26 g of dyeing composition according to Table 9 above and 0.84 g of dyeing composition according to Table 10 above are mixed with 12 g of oxidizing composition according to Table 4 above and 36 g of water stabilized and adjusted to pH 2,2; then, after at least 30 seconds,

[0217] (2) the mixture obtained in stage (1) is mixed with 24 g of thickening composition according to Table 5 above, 28.8 g of alkaline composition 1 (invention) according to Table 2 above and 19.2 g of alkaline composition 2 (invention) according to Table 3 above.

[0218] A homogeneous aqueous composition (M), where the dyeing compositions have dispersed in the aqueous composition (M), is thus obtained.

[0219] The composition (M) obtained is subsequently applied to locks of natural Caucasian hair comprising 90% white hairs (locks of NG hair) in a proportion of 10 g of composition (M) per 1 g of hair. After a leave-in time of 30 minutes at 27° C., the locks are rinsed, washed with a standard shampoo, rinsed again and then dried.

[0220] Results for the Dyeing:

[0221] The colorimetric data for each of the locks are subsequently measured in the CIELab system with a Data Color SF600X spectrophotometer (illuminant D65, angle 10° and specular component included). In this L* a* b* system, L* represents the lightness, a* indicates the green/red colour axis and b* indicates the blue/yellow colour axis. The higher the value of L, the lighter or less intense the colour. Conversely, the lower the value of L*, the darker or more intense the colour. The higher the value of a*, the redder the shade, and the higher the value of b*, the yellower the shade.

[0222] The colour build-up on hair thus corresponds to the variation in colouring between the locks of dyed NG hair and the locks of non-dyed (i.e. untreated) NG hair, which is measured by AE according to the following equation:

ΔE=√{square root over ((L*−L.sub.0*)+(a*−a.sub.0*)+(b*−b.sub.0*))}

[0223] In this equation, L*, a* and b* represent the values measured after dyeing of the locks of NG hair, and L.sub.0*, a.sub.0* and b.sub.0* represent the values measured for the locks of untreated NG hair. The higher the ΔE value, the better the build-up of the colouring.

[0224] The results are collated in the table below:

TABLE-US-00011 TABLE 11 L* a* b* ΔE Lock of untreated NG hair 57.78 1.40 13.97 — Lock of treated NG hair 23.57 2.39  5.25 35.32

[0225] It is apparent from the results of the table that the keratin fibres treated with the composition (M) prepared by means of the cosmetic composition according to the invention are dyed intensely and with a good colour build-up.

[0226] It has also been found that the composition (M) is easy to apply and to spread over the locks of hair, in particular without running.

[0227] Method for Bleaching Keratin Fibres

[0228] A composition (N) for the bleaching of keratin fibres is prepared in a bowl by mixing 12 g of oxidizing composition according to Table 4 above with 36 g of water stabilized and adjusted to pH 2.2, then with 24 g of thickening composition according to Table 5 above and 48 g of alkaline composition 1 (invention) according to Table 2 above.

[0229] A homogeneous aqueous composition (N) is thus obtained.

[0230] The composition (N) obtained is subsequently applied to locks of natural Caucasian hair with a height of tone 4 (HT4) in a proportion of 10 g of composition (N) per 1 g of hair. After a leave-in time of 30 minutes at 27° C., the locks are rinsed, washed with a standard shampoo, rinsed again and then dried.

[0231] Results for the bleaching: [0232] The colour of the locks was evaluated in the CIE L* a* b* system by means of a Data Color SF600X spectrophotometer (illuminant D65, angle 10° and specular component included). In this L* a* b* system, the three parameters respectively denote the intensity of the colour (L*), the green/red colour axis (a*) and the blue/yellow colour axis (b*). [0233] The higher the value of L*, the more the locks are bleached. The higher the value of a*, the redder the shade, and the higher the value of b*, the yellower the shade. The effectiveness of the bleaching is evaluated by the variation in the colour of the locks before and after treatment with the composition (N), and measured by (AE*) according to the following equation:

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

In this equation, L*, a* and b* represent the values measured on the locks of HT4 hair treated with the composition (N), and Lo*, ao* and bo* represent the values measured on the locks of untreated HT4 hair. [0234] The greater the value of ΔE*, the greater the difference in colour of the lock before and after treatment, which shows a more intensive bleaching.

[0235] The results are collated in the table below:

TABLE-US-00012 TABLE 12 L* a* b* ΔE Lock of untreated HT4 hair 21.33 2.84 3.24 — Lock of treated HT4 hair 26.22 6.91 9.43 8.88

[0236] It is apparent from the results of the table above that the keratin fibres treated with the composition (N) prepared by means of the cosmetic composition according to the invention are significantly bleached (L*>L.sub.0 and high ΔE).

[0237] It has also been found that the composition (N) is easy to apply and to spread over the locks of hair, in particular without running.
