Description

Title of the invention: compositions, methods and necessary for modifying hair color technical field

[0001] This disclosure relates to compositions for modifying hair color comprising a hair coloring base, compositions for modifying hair color, and necessities and processes for modifying hair color. CONTEXT

[0002] Modifying or improving the appearance of hair is very popular with consumers, including, for example, changing hair color and / or imparting various properties, such as shine and conditioning. In addition, consumers often wish to apply color to their hair to color or conceal gray hair, for example, on the scalp, facial hair, etc. Hair coloring typically involves bleaching, lightening, and / or changing the hair color by means of oxidative dyes, direct dyes, and / or pigments that provide a different shade or color and / or enhance the hair color.

[0003] Hair lightening or hair color enhancement processes generally require the use of compositions that include at least one oxidizing agent to lighten dark hair to lighter shades. When colorants or tinting compounds such as oxidation tint precursors and / or direct dyes are present in these compositions, they can change or deposit color while simultaneously lightening the hair color. Conventional hair coloring products are permanent tint compositions comprising oxidation tint precursors, also known as primary intermediates or couplers. These oxidation tint precursors are colorless or weakly colored compounds that, when combined with oxidizing agents, give rise to colored complexes through an oxidative condensation process.

[0004] The variation in tone height before and after the application of a hair color modification composition is typically evaluated during hair color lightening or highlighting. The degree or level of lightening or highlighting is determined by this variation. The term "tone" refers to the "finish" of a shade, including its degree of warmth or coolness, and is based on the classification of natural shades, with one tone separating each shade from the The shade that immediately follows or precedes it. Tone levels typically range from 1 (black) to 10 (light blonde), with one unit generally corresponding to one tone. Consequently, the higher the number of tones, the lighter the shade and the greater the degree of enhancement.

[0005] Hair dyeing or color-enhancing compositions may require one or more alkalizing agents, such as ammonia and / or ammonium-based compounds, which cause the hair shaft to swell, thus allowing small oxidizing dye molecules to penetrate the cuticle and cortex before the oxidation condensation process is complete. The larger color complexes resulting from the oxidation reaction are then trapped inside the hair fiber, thereby permanently altering the hair color. Although these dyeing and / or color-enhancing compositions can effectively change hair color, they can damage the hair fibers and / or irritate the scalp due to excessively high levels of alkalinity.

[0006] Moreover, as consumers have become more aware of the potential risks associated with the use of certain chemicals, the demand for cosmetic products, including hair coloring or dyeing compositions, that do not use certain ingredients, has increased.

[0007] The use of new and additional ingredients and new combinations of ingredients is a subject of ongoing research in an attempt to mitigate or avoid damage to hair and / or irritation of the scalp or skin, as well as to provide hair color-enhancing and / or dyeing compositions that do not include, or minimize / limit, the use of mineral oil, certain alkalizing compounds such as ammonia and / or ammonium-based compounds, and / or certain tints such as resorcinol and / or resorcinol derivatives, while still achieving the desired safety and performance objectives. However, the choice of ingredients or combinations of ingredients frequently presents difficulties insofar as they may impair the effectiveness of the composition in depositing or enhancing hair color, or other cosmetic attributes.Ingredient combinations must be considered for attributes such as ease and uniformity of application, rheology or viscosity properties, stability of compositions, color durability and / or formation of the target shade, while weighing potential disadvantages such as increased damage and / or a less healthy appearance of the hair.

[0008] Thus, one objective of the present disclosure is to provide new compositions for modifying hair color that offer consumers desired properties such as ease and uniformity of application, rheological properties, or viscosity, stability of compositions, color durability and / or formation of the target shade.

[0219] Example 6 - Evaluation of colour deposit and coverage

[0220] Inventive and comparative color modification compositions of hair was mixed with equal amounts of aqueous hydrogen peroxide oxidizing compositions (20V or 30V), as shown in Table 6.

[0221] [Tableauxô] Mixture Hair Color Modifying Composition Oxidizing Composition Mixing Ratio Processing Time (minutes) 4H(20) 4H 20V 1:1 30 4H(30) 4H 30V 1:1 30 41(20) 41 20V 1:1 30 41(30) 41 30V 1:1 30 C4(20) C4 20V 1:1 35

[0222] Once the mixtures in Table 6 were prepared, each mixture was applied to four different strands of dark blonde hair at a ratio of 3 grams of mixture to 1 gram of hair, in order to determine the effectiveness of color deposition and coverage for each mixture. After a processing time, the strands were rinsed, shampooed, rinsed again, and dried. Once dry, the strands were evaluated for color deposition and coverage.

[0223] As can be seen in Figures IA and IB, the color deposition and coverage provided by each of the inventive mixtures were comparable to those observed by the comparator mixture, although the comparator mixture had a large amount of mineral oil and a solvent system different from the inventive mixtures.

[0224] This example demonstrates that, surprisingly and unexpectedly, it is possible to obtain satisfactory color deposition and coverage, comparable to traditional hair color modification compositions.

[0225] Example 7 - Evaluation of shade matching

[0226] Inventive and comparative hair colour modification compositions were mixed with equal amounts of aqueous hydrogen peroxide 20V oxidizing compositions, as shown in Table 7.

[0228] Once the mixtures in Table 7 were prepared, each mixture was applied to hair strands at a ratio of 3 grams of mixture per 1 gram of hair, in order to verify the ability of each of the inventive compositions to match the shade of each of the comparative compositions. After a processing time, the strands were rinsed, shampooed, rinsed again, and dried. Once dry, the strands were evaluated.

[0229] As can be seen in Figures 2A to 2D, the shade obtained by each of the inventive mixtures was comparable to that of the respective comparative mixtures, although the comparative mixtures had a large amount of mineral oil, a smaller amount of organic oxidizing agent, and a solvent system different from the inventive mixtures.

[0230] This example demonstrates that, surprisingly and unexpectedly, the hair colour modification compositions according to the disclosure are able to satisfactorily match the shades obtained by traditional hair colour modification compositions. Example 8 - Evaluation of the enhancement

[0231] Inventive and comparative hair colouring bases and hair colour modification compositions were mixed with equal amounts of aqueous oxidizing compositions of 20V hydrogen peroxide, as shown in Table 8. Mixture Base Composition Hair Bleaching / Hair Color Modification Oxidizing Composition Mixing Ratio 2E(20) 2E 20V 1:1 2F(20) 2F 20V 1:1 2M(20) 2M 20V 1:1 4A(20) 4A 20V 1:1 4B(20) 4B 20V 1:1 4G(20) 4G 20V 1:1 Cl(20) Cl 20V 1:1 C3(20) C3 20V 1:1

[0233] Once the mixtures in Table 8 were prepared, each mixture was applied to three (3) different strands of hair (dark brown, dark blonde, light blonde) at a ratio of 3 grams of mixture per 1 gram of hair, in order to verify the ability of each of the inventive compositions to enhance hair color compared to the comparative compositions. After a processing time, the strands were rinsed, shampooed, rinsed again, and dried. Once dry, the strands were evaluated.

[0234] As can be seen in Figures 3A to 3C, the enhancement obtained by each of the inventive mixtures was comparable to that of the respective comparative mixtures, although the comparative mixtures had a large quantity of mineral oil and a solvent system different from that of the inventive mixtures.

[0235] This example therefore demonstrates that, surprisingly and unexpectedly, satisfactory enhancement can be obtained with the hair colour modification compositions according to the disclosure, comparable to the enhancement obtained with traditional hair colour modification compositions. Example 9 - Measuring viscosity

[0236] The viscosities of the base mixtures of hair coloring or of inventive hair color modification compositions combined with equal amounts of aqueous oxidizing compositions of 20V hydrogen peroxide were measured using a Rheomat RM 180, spindle M3 for 180 seconds under ambient conditions, as shown in Table 9. Mixture Base composition of hair coloring / hair color modification Oxidizing composition Mixing ratio Viscosity of the mixture (centipoise) 1H(2O) 1H 20V 1:1 1223 4J(2O) 4J 20V 1:1 1437 4K(2O) 4K 20V 1:1 1076 4L(2O) 4L 20V 1:1 1403

[0238] The mixtures in Table 9 have viscosities considered particularly suitable for effective application on keratinous fibers such as hair, facial hair, etc., without dripping or running.

[0245] Each of the hair color-modifying compositions in Tables 10A and 10B was mixed with equal amounts (mixing ratio 1:1) of an aqueous hydrogen peroxide oxidizing composition. Equal amounts of each mixture were applied to dark blonde hair strands to evaluate wash retention, as shown in Table 10C.

[0247] After an equal processing time for each comparison, the strands were rinsed, shampooed, rinsed again, and dried. Once the strands were dry, the color of each strand was assessed. This color is considered the starting color (0) of the treated strands for this study.

[0248] Subsequently, each strand was shampooed, rinsed, dried, and its color evaluated again, which was repeated for a total of fifteen washes. The color difference (AE) of each strand was calculated after each wash according to the following equation: AE =

[0249] in which L*, a*, and b* represent the values ​​measured before each wash, and Lo*, ao*, and b0* represent the values ​​measured after each wash.

[0250] As can be seen in figures 4A to 4D, the color of the strands treated with compositions 10A to 10D had a wash resistance as good (figures 4A and 4B) or better (figures 4C and 4D) than the color of the strands treated with compositions 10E to 10G.

[0251] The above examples demonstrate that hair colouring bases and hair colour modification compositions are surprisingly capable of achieving satisfactory cosmetic properties for hair, good wash resistance, colour deposition and coverage, shade matching and enhancement comparable to traditional hair colour modification compositions, with a viscosity that allows effective application with minimal dripping or running.

[0252] It will be obvious to those skilled in the art that various modifications and variations can be applied to the compositions and processes of the invention without departing from the spirit or scope of the invention
