Description

Title of the invention: COMPOSITION AND METHOD FOR DYEING AND / OR LIGHTENING KERATIN FIBERS FIELD OF INVENTION

[0001] This disclosure relates, in general, to personal care compositions, and in particular, to compositions and a process for dyeing / 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 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] There is therefore a need for dyeing / lightening products that have good working qualities in addition to good performance, particularly in terms of lightening, color absorption and hair revitalization, which are also environmentally friendly. Summary of the invention

[0181] The vegetable oil (sunflower seed oil) used in the composition, according to the embodiments herein, was purchased commercially from Europe ADM Speciality Oil and Fats (Société Industrielle des Oléagineux).

[0182] Comparative composition A1 was prepared similarly to composition A, except that in composition A1, 0.2 wt% of tetrasodium glutamate diacetate (GLDA) was substituted with 0.2 wt% of ethylenediaminetetraacetic acid (EDTA). Composition A is therefore a more environmentally friendly composition than composition A1

[0183] The ingredients used to prepare compositions A and A1 are provided in Table 1 below, expressed as % by weight.

[0187] EXAMPLE 2:

[0188] Consumer evaluation of work quality

[0189] Protocol: The working qualities, including ease of mixing and application, consistency, ease of emulsification, and ease of rinsing, were tested on consumer participants / volunteers. Four 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 their hair was then blow-dried.

[0190] Each of composition A and comparative composition Al was mixed independently with oxidizing composition B in a weight ratio of 1:1 to obtain mixtures 1 and 2, respectively.

[0191] Each of mixtures 1 (Composition A+B) and 2 (Composition Al+B) was applied to the participants' hair, left for a period of 35 minutes, and then rinsed with water to remove the mixtures.

[0192] The rinsed hair was then blow-dried and evaluated with respect to the above working qualities. Consumers rated 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, the amount of time required to rinse the mixtures, and the feel / texture of the hair after rinsing.

[0193] Results: Mixture 1, comprising composition A, had a creamy, white texture and a medium-thin consistency. Regarding its workability, Mixture 1 was rated as very easy to mix by participants (rated 4 on a scale of 5, with 1 indicating very difficult mixing and 5 indicating very easy mixing) as it did not require many strokes to blend and applied evenly to the hair. It was also rated as very easy to emulsify (4 on a scale of 5, with 1 indicating very difficult emulsification and 5 indicating very easy emulsification) and easy to rinse from the hair. In terms of performance, Mixture 1 also resulted in increased luster, shine, and conditioning effect on the hair, and demonstrated good lightening.

[0194] Mixture 2, comprising Composition A1, had a creamy, white texture and a medium-thick consistency. Regarding its workability, Mixture 2 was rated as easy to mix by participants (rated 3 on a scale of 5, with 1 indicating very difficult mixing and 5 indicating very, very easy mixing), as it required more strokes to blend, and was rated as easy to apply to hair with even coverage. It was also rated as easy to emulsify (rated 3 on a scale of 1 indicating very difficult emulsification and 5 indicating very, very easy emulsification) and easy to rinse out. In terms of performance, Mixture 2 had lower luster and shine, and also a weaker lightening effect.

[0195] Overall, mixture 1 was preferred by consumers to mixture 2 for its working qualities and performance, indicating that the ingredients of composition A work synergistically to provide the desired effects.

[0196] Mixture 1 was judged to be very easy to mix and also very easy to emulsify. The consistency of mixture 1 was also preferred because it had a consistency The thicker, creamier formula was easy to apply, while the consistency of mixture 2 was thinner and not as desirable. Mixture 1 was also judged to give hair a softer, more manageable feel with added shine and a better lightening effect, among other benefits. BENEFITS OF THIS DISCLOSURE

[0197] The composition of this disclosure demonstrates good working qualities. It is easy to mix, emulsify and apply evenly to the hair and, consequently, takes less time to apply while providing good performance in terms of hair lightening and conditioning.

[0198] It is also an eco-responsible composition, as it reduces the use of ingredients that have harmful effects on the environment and replaces them with environmentally friendly alternatives.
