Description

Title of the invention: Composition for dyeing and / or lightening keratin fibers, and their methods FIELD OF INVENTION

[0001] This disclosure relates, in general, to personal care products, and more specifically, to compositions for dyeing and / or bleaching keratin fibers. This disclosure further relates to a process for dyeing and / or bleaching 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 called 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, on 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 decolorizing the melanin pigment in the hair. In this way, the dyes develop in the hair cortex and a uniform color development is obtained.

[0005] The formulation of environmentally friendly cosmetic products, which are designed and developed taking environmental issues into account, is becoming a major objective in the context of efforts to address global challenges.

[0006] It is therefore essential to offer 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 high naturalness index and / or materials of natural origin, and more specifically, materials of plant origin, while reducing the use of petrochemical compounds.

[0007] However, the addition of materials of natural or plant origin to hair dye compositions tends to reduce the shelf life of such compositions, because they are often unstable when stored for long periods, especially when stored at higher temperatures.

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

[0009] In one aspect of this disclosure, a composition is proposed comprising sunflower oil; at least one polyol, at least one cationic polysaccharide, at least one nonionic associative polymer, and at least one oxidative dye and / or at least one alkali agent.

[0010] In another aspect of this disclosure, a kit is proposed comprising a composition (A) including sunflower oil, at least one polyol, at least one cationic polysaccharide, at least one nonionic associative polymer, and at least one oxidative dye and / or at least one alkali agent; and a composition (B) including at least one oxidizing agent, and optionally at least one nonionic polyoxyalkylated fatty alcohol ether, the mixture of composition (A) and composition (B) resulting in a ready-to-use composition.

[0011] In another aspect of this disclosure, a process for dyeing keratin fibers, preferably hair, is proposed, comprising mixing a composition (A) comprising sunflower oil, at least one polyol, at least one cationic polysaccharide, at least one nonionic associative polymer, and at least one oxidative dye and / or at least one alkali agent; and a composition (B) comprising at least one oxidizing agent, and optionally at least one nonionic polyoxyalkylated fatty alcohol ether, to obtain a mixture and applying the mixture to said fibers.

[0012] In another aspect of this disclosure, it is proposed to use a composition comprising sunflower oil, at least one polyol, at least one cationic polysaccharide, at least one nonionic associative polymer and at least one oxidative dye, and / or at least one alkali agent; or a kit comprising a composition (A) which includes sunflower oil, at least one polyol, at least one cationic polysaccharide, at least one nonionic associative polymer, at least one oxidative dye and / or at least one alkali agent, and a composition (B) comprising at least one oxidizing agent, and optionally at least one nonionic polyoxyalkylated fatty alcohol ether, the mixture of composition (A) and composition (B) resulting in a ready-to-use composition for dyeing and / or lightening keratin fibers, such as hair.

[0225] Example 2: Stability assessment

[0226] Each of the compositions A (according to the present invention) and the 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 the 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] Furthermore, 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 composition A of the present invention.

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

[0233] Example 3: Evaluation of slip in the wet state

[0234] The expression "wet glide", as used here, refers to the ease with which a comb moves through keratin fibers, particularly hair, after the application of a composition or product to keratin fibers, in particular a dyeing and / or lightening composition for keratin fibers, in particular human hair, as disclosed herein.

[0235] The ease of movement of the comb in the keratin fibers was measured in terms of force (Fmax) in Newtons (N) required for the comb to move in the keratin fibers, for example, the greater the ease of movement of the comb through the keratin fibers, the lower the Fmax, which indicates a higher level of revitalization and smoothing of the keratin fibers.

[0236] Compositions A (according to the present invention) and A4 (comparative) were each independently mixed 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 processing time of 35 minutes, the hair was rinsed. This was repeated twice, i.e., the mixtures were applied, left on 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 proposed herein, showed the best wet glide as it demonstrated the least resistance to slippage, while composition A4, which was without sunflower oil, demonstrated the least wet glide as the force required for wet glide (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 glide performance, thus providing a more nourishing and revitalizing effect on the hair.
