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 personal care products,
and more particularly, to products and compositions for the dyeing of keratin fibres. The present disclosure further relates to a method for the dyeing of keratin fibres.
BACKGROUNDOFINVENTION
[0002] The use of colorants and developers in dyeing or coloring of hair is
a well-known practice. Efforts towards achieving long lasting effect, uniform color delivery, and improved color effect have resulted in the development and use of various oxidizing dyes, oxidizing agents, etc in hair dyeing products. Typically, in dyeing of hair, the melanin pigment in keratin fibres is decolorized to bleach the hair followed by coloring using a colorant or dye, for eg. oxidative dye. Oxidizing compositions having colorants and developers including oxidizing dye and oxidation agents, respectively, are generally required to be mixed in a bowl which may then be applied to hair. This is often inconvenient for users as it requires prior preparation, especially the provision of bowls, brushes, etc., and is not desirable. Further, such products having varied rheologies often pose issues in achieving optimum spreadability and uniform color delivery on the hair. While it is desirable to achieve creamy and uniform consistency, the use of thickeners or rheology modifiers pose an issue in respect of stability in oxidizing compositions. Such issues of stability may be attributed to the high reactivity of such thickeners with the oxidizing agents.
[0003] Further, the colorant and developers are generally required to remain
on the hair for a pause time of about 30 to 60 minutes, for color development. It is highly desirable to reduce this pause time to achieve faster coloration of hair, especially without compromising color uptake by the keratin fibres. Generally known compositions having oxidizing agents are required to have a pause time of about 60 minutes making hair dyeing a time taking process. Therefore, there is a

need for products that achieve improved cosmetic properties such as uniform color delivery, even color tone, efficient coloration, good conditioning effect, and creamy consistency while having a good consumer feel and improving consumer convenience.

Example 3: Evaluation of viscosity
[0169] The viscosity of Composition 1 and Composition 2 was evaluated in
comparison with a commercially available composition (also referred to herein as Composition 3, depicted in Table 3), using Viscometer model used – pro Rheo Model - R 180 with spindle M3 at 25°C. Viscosities were measured of individual compositions, i.e. Composition 1, Composition 2, and Composition 3. Further, viscosities of the mixtures of the compositions after mixing the Composition 1 with Composition 2 or Composition 3, in a 1:1 ratio, i.e. mixture of Composition 1 and Composition 2 (also referred to herein as Mixture 1); and mixture of Composition 1 and Composition 3 (also referred to herein as Mixture 2), were also measured.
[0170] Composition 3 include 0.06 wt% of tetrasodium etidronate, 0.03
wt% of sodium salicylate, 6 wt % of hydrogen peroxide, 0.04 wt% of tetrasodium pyrophosphate, 2.28 wt% of cetearyl alcohol, 0.85 wt% of trideceth-2 carboxamide MEA, 0.5 wt% of glycerin, 0.57 wt% of ceteareth-25, and water up to 100 wt%.

[0171] Results: The results of the viscosity test are depicted in Table 4. The
viscosity of Composition 2 was observed to be lesser as compared to Composition 3. The difference in viscosities of Composition 3 and 2 was found to facilitate improved cosmetic properties and consumer convenience of the product, according to embodiment herein. It was found that dispensing of the Composition 1 and Composition 3 became uneven due to the difference in viscosities thereby affecting the cosmetic properties and consumer convenience. This difference, and the improved properties, may be attributed to the carefully selected combination of ingredients in the Composition 2 within specific ranges of amounts. For example, Composition 2 include ceteareth-33, mineral oil, ceteareth-60 myristyl glycol which is not present in in the Composition 3.
[0172] Further, on comparison of the viscosities of the combined
compositions, i.e Mixtures 1 and 2, it was observed that the Mixture 1 had creamy consistency as compared to that of Mixture 2, thereby contributing to improved user feel, and improved and uniform spreadability of the mixture/product on keratin fibres. It further led to difference in color delivery as the product was intended to be applied by hands, i.e. without the requirement for brush and bowl. The creamy consistency enabled the composition to be taken by hand for mixing and applying on keratin fibres.

[0173] The coloration achieved by Mixture 1 and Mixture 2 (referred to in
Example 3) was evaluated using L*, a*, b* system. The evaluation of the coloration can be done visually or read on a spectrocolorimeter (such as Minolta CM3600d, illuminant D65, angle 10°, SCI values) for the L*, a*, b* colorimetric measurements. In this L*, a*, b* system, L* represents the intensity of the color, a* indicates the green/red color axis and b* indicates the blue/yellow color axis. The lower the value of L, the darker or more intense the color. The higher the value of a*, the redder the shade; the higher the value of b*, the yellower the shade. The variation in coloring between the colored locks of natural white hair which is untreated (control) and after treatment or coloration are defined by AE*, corresponding to the colour uptake on keratin fibres, according to the following equation:

[0174] 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.
[0175] The greater the value of AE, the greater the difference in color
between the control locks and the dyed locks and greater is the colour uptake.
[0176] Results: The results of the coloration test are depicted in Table 5. A
clear difference on swatches with the 2 mixtures, Mixture 1 and Mixture 2 was observed. It was found that the Mixture 1, having AE of 43.99, had improved colour uptake on keratin fibres as compared to Mixture 2, having AE of 40.39 The higher color uptake was further achieved by the Mixture 1, i.e. the product according to embodiments herein, in reduced pause time. Moreover, the intensity of the color was better with mixture 1 (L* significantly smaller for mixture 1).
