Description

Technical Field

[0001] This disclosure generally relates to personal care compositions, and more particularly to compositions and methods for dyeing / bleaching keratin fibers. Background Technology

[0002] Dyeing keratin fibers, especially human hair, is a well-known practice, typically using coloring compositions that contain oxidized dye precursors (often called oxidizing bases) and color couplers. These dye precursors are colorless or light-colored compounds. When combined with oxidizing agents, they generate colored compounds through an oxidative condensation process.

[0003] Oxidative staining methods typically involve applying an oxidizing base or a mixture of an oxidizing base and a colorant, or adding an oxidizing agent during use, to keratin fibers.

[0004] This method is typically carried out at an alkaline pH level, which dyes and bleaches the hair fibers by decolorizing the melanin in the hair. This allows the colorant to penetrate the hair cuticle, achieving a uniform color.

[0005] Environmentally friendly cosmetic formulations designed and developed with environmental concerns in mind are becoming an important goal in addressing global challenges.

[0006] Therefore, it is essential to develop more sustainable compositions, preparation methods, and ingredients to address these environmental concerns. In this context, developing novel cosmetic compositions with lower carbon footprints is crucial, particularly by promoting the use of renewable raw materials and / or materials with good naturalness indices and / or naturally derived materials, especially plant-based materials, while reducing the use of petrochemical-derived compounds.

[0007] Therefore, there is a need for coloring / bleaching products that have good working qualities and performance, especially in bleaching, color absorption and hair conditioning, and are also environmentally friendly.

It should be understood that this disclosure is not limited to the specific methods and experimental conditions described, as such methods and conditions may also be applicable.

[0167] Example 1 Composition for staining keratin fibers Composition A (according to the present invention) is prepared from the following components: 6 wt% vegetable oil, i.e., sunflower seed oil; polyol, i.e., 5 wt% propylene glycol; cationic polysaccharide, i.e., 0.5 wt% guar hydroxypropyltrimethylammonium chloride; 0.05 wt% cetyl hydroxyethyl cellulose; carboxylic acid, i.e., 0.2 wt% tetrasodium diacetate of glutamate; surfactant, i.e., 1.50 wt% lauryl ether-12, 3 wt% lauryl ether-4, 1.50 wt% oleyl ether-20 and 2.40 wt% polysorbate 21; fatty alcohol, i.e., 17 wt% cetearyl alcohol; alkalinizing agent, i.e., 7.83 wt% ethanolamine; fatty acid, i.e., 0.32 wt% stearic acid, 0.02 wt% myristic acid and 0.26 wt% palmitic acid; 0.25 wt% ascorbic acid; 0.75% sodium metabisulfite; and water (up to 100 wt%).

[0168] According to the embodiments described herein, the vegetable oil (sunflower seed oil) used in the composition is commercially available from Europe ADM Speciality Oil and Fats (Société Industriélle des Oleagineux).

[0169] The preparation of composition A1 is similar to that of composition A, except that 0.2% by weight of tetrasodium glutamate diacetate (GLDA) in composition A1 is replaced by 0.2% by weight of ethylenediaminetetraacetic acid (EDTA). Therefore, composition A is more environmentally friendly than composition A1.

[0170] Table 1 below lists the components used to prepare compositions A and A1, expressed in weight percent.

[0171] Table 1 .

[0172] Oxidative composition B is prepared from the components shown in Table 2 below, the contents of which are expressed in weight %: Table 2 .

[0173] Example 2: Consumer reviews of operational characteristics Experimental protocol: Handling characteristics were tested on consumers / volunteers, including ease of mixing and application, consistency, and ease of emulsification and rinsing. Four participants with medium to long hair, moderate to heavy hair volume, and 0% to 20% gray hair were selected. All participants shampooed their entire head and then blow-dried it before applying the composition.

[0174] Composition A and comparative composition A1 were respectively mixed with oxidized composition B at a weight ratio of 1:1 to obtain mixtures 1 and 2.

[0175] Mixture 1 (composition A+B) and mixture 2 (composition A1+B) were applied to the participants’ hair, left to stand for 35 minutes, and then rinsed with water to remove the mixtures.

[0176] The rinsed hair was then blow-dried, and the above-described operational characteristics were evaluated. Consumers evaluated the time required to mix the composition, the speed at which the composition emulsified, the number of brush strokes and the time required to apply the composition evenly to the hair, the time required to rinse off the mixture, and the feel / texture of the hair after rinsing.

[0177] Results: Mixture 1, containing composition A, had a creamy texture, was white, and of medium consistency. Regarding its handling characteristics, participants found Mixture 1 to be very easy to mix (out of 5, where 1 indicates very difficult to mix and 5 indicates very easy to mix) because it required little stirring and could be applied evenly to the hair. Furthermore, Mixture 1 was also considered to be very easy to emulsify (out of 5, where 1 indicates very difficult to emulsify and 5 indicates very easy to emulsify) and easy to rinse off the hair. In terms of performance, Mixture 1 also provided better shine, luster, and conditioning effects on the hair, and exhibited good bleaching properties.

[0178] Mixture 2, containing composition A1, has a creamy texture, is white, and of medium consistency. Participants found Mixture 2 easy to mix (out of 5, 1 being very difficult to mix and 5 being very easy to mix) because it required more stirring to blend and was easy to apply evenly to the hair. It was also easy to emulsify (out of 5, 1 being very difficult to emulsify and 5 being very easy to emulsify) and easy to rinse off the hair. In terms of performance, Mixture 2 had lower shine and gloss, and poorer bleaching effect.

[0179] Overall, consumers preferred mixture 1 over mixture 2 due to its operational characteristics and performance, suggesting that the components of composition A have a synergistic effect to produce the desired results.

[0180] Mixture 1 was found to be very easy to mix and emulsify. The consistency of Mixture 1 is also preferred because it has a thicker, more creamy consistency, making it easier to apply; while Mixture 2 has a thinner consistency and is less preferred. Mixture 1 was also found to make hair smoother, shinier, and to have better bleaching effects, among other things.

[0181] The advantages of this disclosure The composition disclosed herein exhibits excellent handling properties. It is easy to mix, emulsify, and apply evenly to the hair, thus saving time in application, while providing good performance in hair bleaching and conditioning.

[0182] It is also an environmentally friendly composition because it reduces the use of environmentally harmful ingredients and replaces them with environmentally friendly alternatives.
