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 compositions for dyeing and/or lightening keratin fibres. The present disclosure further relates to a method for dyeing and/or lightening keratin fibres.
BACKGROUNDOFINVENTION
[0002] The dyeing of keratin fibres, particularly human hair, is a well-
known practice, and commonly involves the use of coloring compositions, which comprise oxidation dye precursors, generally referred to as oxidation bases and couplers. These dye precursors are colourless or weakly coloured compounds. When combined with an oxidizing agent, they give rise, by a process of oxidative condensation, to coloured compounds.
[0003] Typically, the method of oxidation dyeing involves applying, to
keratin fibres, oxidation bases, or a mixture of oxidation bases and couplers, with an oxidizing agent, which is added at the time of use.
[0004] Generally, this method is implemented at an alkaline pH, and
produces a dyeing and, at the same time, a lightening of the fibre, by the decolourization of the melanin pigment in hair. In this manner, the colourants develop into the cortex of hair and a uniform colour development is achieved.
[0005] The formulation of environmentally friendly cosmetic products,
which are designed and developed considering environmental issues, is becoming a major goal in an effort to meet global challenges.
[0006] It is therefore essential to propose more sustainable compositions,
preparation processes and ingredients to address these environmental concerns. In this context, it is important to develop new cosmetic compositions with a better carbon footprint, particularly by promoting the use of renewable raw materials and/or materials with a good index of naturalness and/or materials of natural origin

and, more particularly, materials of plant origin while reducing the use of compounds of petrochemical origin.
[0007] However, the addition of natural or plant-based origin materials in
hair dyeing compositions tends to reduce the shelf-life of such compositions, as they are often unstable when stored over long periods of time, especially when stored at higher temperatures.
[0008] Thus, there is a need for more sustainable hair dyeing compositions
that achieve superior performance benefits such as long-lasting colour, improved conditioning, protection from hair damage, while also having a long-shelf life.

Example 2: Evaluation of stability
[0213] Each of the compositions A (according to the present invention) and
comparative compositions A1, A2, and A3 were stored for 2 months at 4oC, room temperature (or ambient temperature), 37oC, and 45oC.
[0214] The amount of oil retained in each compositions was measured by
HPLC-CAD (HPLC with charged aerosol detection) method.

[0215] Results: The results of the stability of oils after storage at different
temperatures for 2 months in composition A and comparative compositions A1, A2, and A3 are provided in Table 3 below in which the percentages of oil retained in the compositions are indicated. Composition A comprising sunflower oil was the most stable across all temperatures, in particular, at a high storage temperature of 45oC , 86.27% of sunflower oil was stable i.e. it was retained in its original state, compared to only 37.50% for rapeseed oil in composition A2, for instance.

[0216] In addition, no rancid odour was observed for the compositions after
2 months at all the temperatures.
[0217] Further, assessment of the physical characteristics of the
compositions determined that colour change was observed in the comparative composition A2 comprising rapeseed oil, while no colour change was in the composition A of the present invention.
[0218] The results, therefore, demonstrated that the specific combination of
ingredients in composition A (according to the present invention), function synergistically, and reduced the hydrolysis of sunflower oil, imparted stability and thereby provided the composition having a long shelf life even when stored at high temperatures.
Example 3: Evaluation of Wet-Sliding
[0219] The term “wet sliding”, as used herein, refers to ease of the
movement of a comb through keratin fibres, particularly hair, after the application

of a composition or product on the keratin fibres, in particular, a composition for dyeing and/or lightening of keratin fibres, particularly human hair, according to the present disclosure.
[0220] The ease of movement of the comb through the keratin fibres was
measured in terms of the force (Fmax) in Newton (N) required for the comb to move through the keratin fibres, for instance, the higher the ease of movement of the comb through keratin fibres, the lower the Fmax, which indicated higher level of conditioning and smoothening of keratin fibres.
[0221] The compositions A (according to the present invention), and A4
(comparative) were each independently mixed with the oxidizing composition B in a weight ratio 1 / 1.
[0222] Each of the mixtures was applied on natural human hair, in a
proportion of 5g of mixture per 1g of hair, 27cm in length. After a leave-on time of 35 minutes, the hair was rinsed. This was repeated twice, i.e. the mixtures were applied, left-on 35 minutes and rinsed three times.
[0223] For each of the compositions, the wet sliding was measured using a
Sliding bench instrument.
[0224] Results: As shown in the Table 4 below, the composition A
comprising 6% sunflower oil, as provided herein, showed the best wet-sliding as it demonstrated the least resistance to sliding, while composition A4, which was without sunflower oil, demonstrated the least wet-sliding as the force required for wet-sliding (Fmax) on composition A4 was significantly higher than required for composition A. The results indicated that the compositions, according to the present invention, comprising sunflower oil, demonstrated the best wet-sliding performance, thereby providing a more nourishing and conditioning effect to hair.

ADVANTAGES OF THE PRESENT DISCLOSURE
[0225] The composition of the present invention achieves improved wet-
sliding and nourishment of hair. In particular, the composition of the present invention, includes sunflower oil, which contributes to the superior properties of smoother and more uniform feel to hair, along with better shine, and repair of damaged hair without leaving a feel perceived to be greasy. Moreover, the composition of the present invention is stable, particularly at higher temperatures. The composition also achieves long-lasting colour and improved comesticity.
