Description

Title of the invention: COMPOSITIONS AND METHODS FOR DYEING AND / OR LIGHTENING KERA- FIBERS TINEUSES FIELD OF INVENTION

[0001] This disclosure relates, in general, to cosmetic products, and in particular, to cosmetic compositions for hair. Specifically, this disclosure relates to compositions and processes for dyeing and / or lightening keratin fibers. CONTEXT OF THE INVENTION

[0002] Dyeing keratinous 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] Generally, the oxidation dyeing process involves the application, on keratinous 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 uniform color development is achieved.

[0005] The formulation of environmentally friendly cosmetic products, which are designed and developed taking environmental issues into account, is becoming a major objective in an effort 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 lower carbon footprint, particularly 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] Thus, there is a need for dyeing / lightening products that have good working qualities in addition to good performance, particularly in terms of level of lightening, colour uptake and hair revitalisation, which are also environmentally friendly. Summary of the invention

[0008] In one aspect of this disclosure, a composition is proposed comprising at least 3% by weight of at least one vegetable oil, relative to a total weight of the composition; at least one fatty acid other than the vegetable oil; at least 10% by weight of at least one solid fatty compound other than the vegetable oil and the fatty acid, relative to a total weight of the composition; at least one cationic polysaccharide; and at least one oxidative dye and / or at least one alkaline agent.

[0009] In another aspect of this disclosure, a dyeing / lightening process for keratinous fibers is proposed, comprising the application of a composition comprising at least 3% by weight of at least one vegetable oil, relative to a total weight of the composition; at least one fatty acid other than the vegetable oil; at least 10% by weight of at least one solid fatty compound other than the vegetable oil and the fatty acid, relative to a total weight of the composition; at least one cationic polysaccharide; and at least one oxidative dye and / or at least one alkaline agent, to said keratinous fibers.

[0010] In another aspect of this disclosure, it is proposed to use a composition comprising at least 3% by weight of at least one vegetable oil, relative to a total weight of the composition; at least one fatty acid other than the vegetable oil; at least 10% by weight of at least one solid fatty compound other than the vegetable oil and the fatty acid, relative to a total weight of the composition; at least one cationic polysaccharide; and at least one oxidative dye and / or at least one alkaline agent for dyeing / lightening keratinous fibers, such as hair.

[0175] Composition for lightening keratinous fibers

[0176] Composition A (according to the invention) for dyeing / lightening keratinous fibers was prepared using 6% by weight of vegetable oil (i.e., sunflower oil); polyol, i.e., 5% by weight of propylene glycol; cationic polysaccharide, i.e., 0.5% by weight of guar hydroxypropyltrimonium chloride; nonionic associative polymer, i.e., 0.05% by weight of cetyl hydroxyethylcellulose; 0.24% by weight of tetrasodium glutamate diacetate; surfactants, i.e., 1.50% by weight of laureth-12, 3% by weight of laureth-4, 1.50% by weight of oleth-20 and 2.40% by weight of polysorbate 21; solid fatty compounds, i.e., 17% by weight of cetearyl alcohol; alkaline agent, i.e., 7.83% by weight of ethanolamine; fatty acids, namely 0.32% by weight of stearic acid, 0.02% by weight of myristic acid and 0.26% by weight of palmitic acid; 0.25% by weight of ascorbic acid; 0.75% by weight of sodium metabisulfite; and water (to make up to 100% by weight).

[0177] The vegetable oil (sunflower oil) used in the composition, according to the embodiments herein, was commercially obtained from Europe ADM Speciality Oil and Fats (Société Industrielle des Oléagineux).

[0178] Comparative composition B was prepared similarly to composition A, except that in composition B, the amount of vegetable oil was reduced to 1%. Comparative composition C was also prepared similarly to composition A, except that it was prepared without vegetable oil.

[0179] The ingredients used to prepare compositions A, B and C are provided in Table 1 below, expressed as % by weight.

[0181] Oxidizing composition D was prepared from the ingredients whose contents are indicated in Table 2 below, expressed as % by weight:

[0182] [Table 2] Table 2 Ingredients Composition D Stabilizing and chelating agents QS Hydrogen peroxide 6.00 Cetearyl alcohol 2.28 Ceteareth-25 0.57 Trideceth-2 carboxamide mea 0.85 Glycerol 0.50 Phosphoric acid qs pH 2.2 Water qs 100

[0183] Example!: Color change assessment

[0184] Protocol: Color modification, i.e., the ability to lighten / The bleaching of the compositions was tested in vitro on untreated samples of virgin / untreated Indian black hair. Each of composition A and comparative composition B was independently mixed with oxidizing composition D in a 1:1 weight ratio to obtain mixtures 1 and 2, respectively.

[0185] Each of mixtures 1 and 2 was applied to the hair strands and left for a processing time of 35 minutes. The hair strands were then rinsed to remove the mixtures and oven-dried.

[0186] The color or lightening of the hair strands was measured using a spectrocolorimeter (such as the CM-2600D spectrocolorimeter) with an integrating sphere and D65 illumination. The color was detected in the CIELAB 1976 color space using three Cartesian colorimetric coordinates: L* (lightness), a* (red-green axis), and b* (blue-yellow axis). The color can also be expressed in this space with components more descriptive in terms of visual perception, with the polar coordinates C* and h expressing saturation and hue angle.

[0187] The color difference, AE, which expresses the perceived difference between two colors, can be calculated from the colorimetric coordinates L*, a* and b*.

[0188] It is calculated as follows: AEL — + ) Z + (J3 — b... F

[0189] By calculating the color difference between hair strands before and after the application of the hair coloring product, the increase in coloring / lightening of the hair strands, and therefore its coloring / lightening performance, was characterized. Consequently, the greater the color difference, AE, between the hair strands before and after the application of the hair coloring product, the better the coloring / lightening performance. Calculating the color difference between two colored / lightened hair strands reveals whether any color differences between them can be visually perceived or not.

[0190] Results: The results of the color test are provided in Table 3. The greatest difference in color / lightening was observed for mixture 1 comprising composition A, which had an AE value of 8.54. Mixture 2 comprising the comparative composition B showed a minimal difference in color / lightening and had almost the same AE values ​​of 6.44, respectively. Composition A, which included 6% vegetable oil, clearly allowed for lightening capacity, while the comparative composition with an amount A very minimal amount (1%) of oil was unable to achieve the same effect. It is clear that the higher quantity of vegetable oil in formula A works synergistically with the ingredients, as shown in Table 1, and provides superior lightening.

[0191] [Table 3] Table 3 Mixture 1 (Composition A + Composition D) Mixture 2 (Composition B + Composition D) A Values ​​E 8.54 6.44

[0192] Example 3: Evaluation of the revitalization effect

[0193] Protocol: The revitalizing effect is tested in vitro on untreated samples of Indian human hair. Each of mixtures 1 and 2, as prepared in Example 2, was applied to the hair strands and left for a period of 35 minutes. The hair strands were then rinsed to remove the mixtures and oven-dried.

[0194] The revitalization effect was assessed by a panel of experts (8 evaluators).

[0195] Results: The revitalizing effect was rated as highest for mixture 1 comprising composition A, while for mixture 2 comprising composition B, the revitalizing effect was rated with a negligible improvement in sensory quality, i.e., smooth texture and softness. Mixture 1 resulted in a feeling of softness, suppleness, and smooth texture in the hair strands, as well as luster. The hair strands were also easy to comb. It was observed that composition A, containing 6% vegetable oil, was able to effectively revitalize the hair, whereas the comparative composition with a very minimal amount (1%) of oil did not offer the same revitalizing effect.

[0196] Example 4:

[0197] Consumer evaluation of coloring and workability

[0198] Protocol: The coloring and workability qualities, including ease of mixing and application, consistency, ease of emulsification, and ease of rinsing, were tested on consumer participants / volunteers. Eight participants with medium to long hair, a medium to high volume, and 0% to 20% gray hair were selected. Before applying the compositions, the participants' heads were thoroughly shampooed, and the hair was subsequently blow-dried. Each of composition A and the comparative composition C was independently mixed with the oxidizing composition D in a 1:1 weight ratio.

[0199] Each of mixtures 1 (composition A+D) and 3 (composition C+D) was applied to the participants' hair, left for a period of 35 minutes, then rinsed with water to remove the mixtures, and the hair was blow-dried.

[0200] Consumers appreciated the time required to mix the compositions, the speed at which the compositions emulsified, the number of brush strokes and the time required to apply the composition evenly to the hair, and the time required to rinse the mixtures. They also evaluated the change in color of the treated hair after the drying step.

[0201] Results:

[0202] Lightening: Overall, mixture 1 comprising composition A had a better lightening / bleaching effect and a better gloss for each participant. The lightening / bleaching effect was lower in mixture 3 for each participant.

[0203] Mixture 1 comprising composition A was also preferred by participants for its ease of emulsification and rinsing of hair, compared to mixture 3.

[0204] Overall, mixture 1 was preferred by the participants for its good workability and coloring qualities, i.e. lightening / bleaching effect. BENEFITS OF THIS DISCLOSURE

[0205] The composition of the present invention improves color modification in terms of lightening / bleaching while also offering good working qualities such as ease of emulsification and rinsing. The composition also demonstrates good nourishment and revitalization of the hair, contributing to a smooth texture and a supple feel. This is achieved, in part, due to the incorporation of an appropriate amount of vegetable oil in the composition of the present invention, which also results in an environmentally friendly composition with reduced reliance on artificial ingredients.
