Description

Title of the invention: COMPOSITION FOR DYEING AND / OR LIGHTENING KERATIN FIBERS, AND METHODS THEREOF FIELD OF THE INVENTION

[0001] The present disclosure relates, in general, to personal care products, and more particularly, to compositions for dyeing and / or lightening keratin fibers. The present disclosure further relates to a method for dyeing and / or lightening keratin fibers. CONTEXT OF THE INVENTION

[0002] Dyeing keratin fibers, particularly human hair, is a well-known practice and commonly involves the use of coloring compositions, which include oxidation dye precursors, generally referred to as oxidation bases and couplers. These dye precursors are colorless or weakly colored compounds. When combined with an oxidizing agent, they give rise, through a process of oxidative condensation, to colored compounds.

[0003] Typically, the oxidation dyeing process involves the application, to keratin fibers, of 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 process is carried out at an alkaline pH, and produces dyeing and, at the same time, lightening of the fiber, by bleaching the melanin pigment in the hair. In this way, the dyes develop in the cortex of the hair and a uniform color development is obtained.

[0005] The formulation of environmentally friendly cosmetic products, which are designed and developed with environmental issues in mind, is becoming a major objective in the efforts to address 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, in particular by promoting the use of renewable raw materials and / or materials with a good naturalness index 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 materials of natural or vegetable origin in hair dye compositions tends to reduce the shelf life of such compositions, as they are often unstable when stored for long periods, especially when stored at higher temperatures.

[0008] Thus, there is a need for longer lasting hair dye compositions that achieve superior performance benefits such as long lasting color, enhanced conditioning, protection against hair damage, while having a long shelf life. Summary of the invention

[0225] Example 2: Stability Assessment

[0226] Each of compositions A (according to the present invention) and comparative compositions A1, A2 and A3 was stored for 2 months at 4°C, room temperature (or ambient temperature), 37°C and 45°C.

[0227] The amount of oil retained in each composition was measured by HPLC-CAD method (HPLC with charged aerosol detection).

[0228] Results: The results of the stability of the 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 at all temperatures, in particular, at a high storage temperature of 45°C, 86.27% of the sunflower oil was stable, i.e., it was preserved in its original state, compared to only 37.50% for rapeseed oil in composition A2, for example.

[0229] [Table 3]Table 3 Stability of sunflower oil in Composition A Stability of coconut oil in Composition A1 Stability of rapeseed oil in Composition A2 Stability of caprylic capric triglyceride in Composition A3 2 months at 4°C 97.27% 93.71% 86.80% 90.05% 2 months at room temperature 92.45% 89.15% 84.71% 86.99% 2 months at 37°C 89.96% 77.95% 38.31% 68.89% 2 months at 45°C 86.27% 79.59% 37.50% 65.49%

[0230] Additionally, no rancid odor was observed for the compositions after 2 months at all temperatures.

[0231] Furthermore, the assessment of the physical characteristics of the compositions determined that a color change was observed in the comparative composition A2 comprising rapeseed oil, whereas no color change was observed in the composition A of the present invention.

[0232] The results therefore demonstrated that the specific combination of ingredients in composition A (according to the present invention) works synergistically and reduces the hydrolysis of sunflower oil, confers stability and thus provides the composition with a long shelf life even when stored at elevated temperatures.

[0233] Example 3: Evaluation of wet slip

[0234] The term "wet slip" as used herein refers to the ease of movement of a comb through keratin fibers, particularly hair, after the application of a composition or product to keratin fibers, in particular a composition for dyeing and / or lightening keratin fibers, in particular human hair, according to the present disclosure.

[0235] The ease of movement of the comb through the keratin fibers was measured in terms of the force (Fmax) in Newton (N) required for the comb to move through the keratin fibers, e.g., the greater the ease of movement of the comb through the keratin fibers, the lower the Fmax, indicating a higher level of conditioning and smoothing of the keratin fibers.

[0236] Compositions A (according to the present invention) and A4 (comparative) were each mixed independently with oxidizing composition B in a weight ratio of 1 / 1.

[0237] Each of the mixtures was applied to natural human hair, in a proportion of 5 g of mixture to 1 g of hair, 27 cm long. After a setting time of 35 minutes, the hair was rinsed. This was repeated twice, i.e. the mixtures were applied, left for 35 minutes and rinsed three times.

[0238] For each of the compositions, wet slip was measured using a slip bench instrument.

[0239] Results: As shown in Table 4 below, Composition A comprising 6% sunflower oil, as provided herein, showed the best wet slip as it demonstrated the least slip resistance, while Composition A4, which was without sunflower oil, demonstrated the least wet slip as the force required for wet slip (Fmax) on Composition A4 was significantly higher than that required for Composition A. The results indicated that the compositions, according to the present invention, comprising sunflower oil, demonstrated the best wet slip performance, thus providing a more nourishing and conditioning effect to the hair.

[0240] [Table 4] Table 4 Wet slip Compositions A A4 Fmax (N) 0.72 0.96 BENEFITS OF THIS DISCLOSURE

[0241] The composition of the present invention achieves improved wet slip and hair nourishment. In particular, the composition of the present invention includes sunflower oil, which contributes to the superior properties of a smoother and more even feel on the hair, as well as improved shine and re repairing damaged hair without leaving a perceived greasy feeling. In addition, the composition of the present invention is stable, particularly at higher temperatures. The composition also achieves long-lasting color and improved cosmeticity.
