COMPLETE SPECIFICATION
The following specification particularly describes the invention and the manner in which it
is to be performed.

FIELDOFINVENTION
[0001] The present disclosure relates, in general, to cosmetic products, and
more particularly, to compositions for the dyeing and/or lightening of keratin fibres. The present disclosure further relates to methods and kits for dyeing and/or lightening of keratin fibres.
BACKGROUNDOFINVENTION
[0002] Oxidizing compositions are used in cosmetics for the purposes of
dyeing, bleaching, and permanently reshaping keratin fibres, such as the hair.
[0003] When used for the purposes of dyeing keratin fibres, oxidizing
compositions are commonly used for oxidative dyeing and direct dyeing. In oxidative dyeing, oxidizing compositions are mixed with oxidation dyes (bases and couplers), which are intrinsically colourless, to generate coloured and colouring compounds via a process of oxidative condensation. In direct dyeing methods, oxidizing compositions are used with direct dyes, which are coloured and colouring substances, to obtain colouring with a lightening effect on the hair.
[0004] Oxidizing compositions may also be used for bleaching keratin
fibres, such as hair. In bleaching reactions, oxidizing compositions can be used alone and applied to keratin fibres to bleach the hair. They may also be used in combination with compositions comprising peroxygenated salts such as persulfates when the oxidizing composition is based on hydrogen peroxide.
[0005] Permanently reshaping keratin fibres, involves the opening of the -
S-S disulfide bonds of keratin (cystine) using a composition containing a suitable reducing agent (reduction step). After rinsing the treated fibres, the disulfide bonds are reconstituted, which requires that the fibres are placed under tension beforehand (curlers and others), and then applying an oxidizing composition (oxidation step, also known as the fixing step) to finally give the hair the desired shape. This technique thus makes it possible, without preference, either to make the hair wavy or to relax or uncurl it. The new shape given to the hair by a chemical treatment

such as that above is eminently long-lasting and especially withstands the action of washing with water or shampoos, as opposed to the simple standard techniques of temporary reshaping, such as hair setting.
[0006] Oxidizing compositions conventionally used in the dyeing
(oxidation dyeing or direct dyeing), bleaching or permanent reshaping of keratin fibres suffer from poor cosmetic performance qualities. In particular, in respect of dyeing, currently used oxidizing compositions lack good dyeing and lightening effects, demonstrate poor colour uptake, and chromaticity. Thus, there is a requirement for oxidizing compositions which lead to good dyeing or lightening properties, especially in terms of power, chromaticity and selectivity with good working qualities and providing good cosmetic properties.

composition comprising at least one oxidizing agent, at least one fatty alcohol, at least one oxyalkylenated fatty alcohol, at least one oxyalkylenated fatty amide, and water, wherein the total amount of the oxyalkylenated fatty amide(s) is greater than 1.5% by weight, relative to the total weight of the composition, and the composition has a pH of less or equal to 5.

Example 2: Evaluation of dyeing and/or lightening effect
[0137] Protocol: The oxidizing compositions A, C1, and C2 were each
mixed with the dye composition B, each mixture in a weight ratio of 1:1.
[0138] Each of the mixtures was applied to locks of natural 90% white hair,
in a proportion of 5 g of mixture per 1 g of hair.
[0139] After a leave-on time of 35 minutes on a hot plate at 27°C, the hair
was rinsed, washed with a standard shampoo, and dried.

[0140] Results: The colouration of the hair was evaluated with a
spectrocolorimeter Minolta CM3600d, illuminant D65, angle 10°, SCI values for
the L*, a*, b* colorimetric measurements.
[0141] In this L*, a*, b* system, L* represents the intensity of the colour,
a* indicates the green/red colour axis and b* indicates the blue/yellow colour axis.
The lower the value of L, the darker or more intense the colour.
[0142] The variation in colouring between the locks of natural white hair
which is untreated (control) and after treatment or coloration are defined by ΔE,
corresponding to the colour uptake on keratin fibres, according to the following
equation:
[0143] In this equation, L*, a* and b* represent the values measured after
dyeing the natural hair comprising 90% of white hairs and L0*, a0* and b0* represent the values measured for the untreated natural hair comprising 90% of white hairs.
[0144] The greater the value of AE, the greater the difference in colour
between the control locks and the dyed locks and the greater colour uptake is.
[0145] Table 3 provides the results of the application of the oxidizing
compositions on hair:
Table 3

ΔE
A + B (invention) 40.18
C1 + B (comparative) 38.10
C2 + B (comparative) 38.13
[0146] The results from Table 3 demonstrated that the inventive
composition A, that comprised the oxyalkylenated fatty amide in an amount that is greater than 1.5 wt% relative to the total weight of the composition, clearly showed a significantly better colour uptake with a difference of AE > 2 in comparison to the

comparative compositions C1 and C2 which comprised the oxyalkylenated fatty amide in an amount that is less than 1.5% by weight.
[0147] Therefore, the composition according to the present invention shows
good colour uptake, chromaticity, and colour visibility with long-lasting colour. In addition, the oxidizing composition according to the present invention had a non-drippy and thicker texture that was easy to apply on hair and was also easy to rinse out as it did not leave an oily residue.
[0148] Moreover, the oxidizing composition according to the present
invention also imparted a good shine and smoothness to hair.
ADVANTAGES OF THE PRESENT DISCLOSURE
[0149] The oxidizing composition of the present disclosure demonstrates
good performance in terms of dyeing and/or lightening of hair and also shows good working qualities. The composition provides good bleaching efficiency, good colour uptake, and chromaticity, with long-lasting colour. In terms of its working qualities, the composition has a non-drippy texture, is easy to apply to the hair in a uniform manner, and is easy to rinse out, with mistake-proof application and therefore, is less time-consuming to apply. The composition also does not weigh down hair with an oily residue and instead provides a shine, smoothness and softness to hair.
