Description

Title of the invention: Compositions and methods for modifying hair color technical field

[0001] This disclosure relates to hair colour modification compositions and methods of using compositions to modify hair colour, while simultaneously strengthening the integrity of hair fibres. CONTEXT

[0002] It is known that consumers wish to use cosmetic compositions to enhance the appearance of keratinous substrates such as hair, for example, by changing the color, style and / or shape of the hair, and / or by imparting various properties to the hair, such as shine and conditioning. Many of the compositions and processes known to enhance the appearance of hair involve chemical treatment of the hair.

[0003] For example, the hair color modification process may involve enhancing hair color by depositing an artificial color onto the hair, thereby imparting a different shade or color to the hair. The hair color enhancement process, also known as lightening, generally requires the use of compositions that include at least one oxidizing agent. These oxidizing agents penetrate the hair shaft and react with the melanin in the hair, thus lightening the hair color. Additional agents, such as persulfate salts, may be added to accelerate the process.

[0004] A color change or color effect on hair can be achieved using permanent, semi-permanent, or temporary hair coloring products. Conventional permanent hair coloring products are colorant compositions comprising oxidation dye precursors, also known as intermediates or primary couplers. These oxidation dye precursors are colorless or weakly colored compounds which, when combined with oxidizing agents, give rise to colored complexes through an oxidative condensation process. Oxidizing agents typically use peroxides such as hydrogen peroxide.

[0005] On the other hand, semi-permanent or temporary hair dye compositions typically use pigments, liposoluble dyes, direct dyes Direct dyes are chosen from among acidic (anionic), basic (cationic), or neutral dyes that are deposited onto the hair fiber to color the hair. Direct dyes are non-ionic or ionic dyes and colored compounds capable of producing a more or less pronounced change in the natural hair color, resistant to multiple shampooings. These dyes may or may not be used with an oxidizing agent. Unlike oxidative dye precursors, a direct dye is a relatively large molecule that does not easily penetrate the core of the hair fiber.

[0006] Hair lightening or color-enhancing compositions and hair dye compositions possess such alkalinity that these compositions have a pH value greater than 7, typically 9 and above, and may generally require the presence of ammonia or an ammonia gas-generating compound, or other alkalizing agents such as monoethanolamine (MEA) in sufficient quantities to render these compositions alkaline. These alkalizing agents cause the hair shaft to swell, helping to open the cuticle, thus allowing small molecules of oxidative dye to penetrate the cuticle and cortex before the completion of the oxidation condensation process. The larger color complexes resulting from the oxidative reaction are then trapped inside the hair fiber, thus permanently altering the hair color.

[0007] Although such compositions can effectively alter hair color, these chemical treatments using these compositions are harsh and can damage hair fibers and reduce hair strength, and can also negatively affect sensory properties, such as smoothness, shine, and feel of the hair. Furthermore, hair damaged during a bleaching and / or dyeing process may not absorb color satisfactorily, resulting in uneven or inconsistent color.

[0008] Thus, in order to reduce or avoid these drawbacks of hair color modification products and processes as described above, new and additional ingredients and combinations of ingredients that can help prevent, improve, or reverse damage before, during, after, or as a complement to hair color modification processes are constantly being sought. However, the choice of ingredients or combinations of ingredients could pose difficulties insofar as they must not impair other cosmetic attributes such as ease and uniformity of application, the rheological or viscosity properties of the compositions, the stability of the compositions, and / or color deposition and the formation of a target shade, and they must not leading to further problems such as increased damage or a less healthy appearance of the hair.

[0009] As it stands, there is therefore a need to develop new and improved products that can be used to effectively modify hair color, while maintaining or improving hair integrity during coloring and preventing or minimizing damage to the hair. This disclosure addresses these concerns and needs and relates to hair color-modifying compositions incorporated with bonding agents to maintain and / or strengthen the integrity of chemically treated and / or damaged hair during hair color modification.

III. Processes

[0166] The compositions described herein can effectively alter hair color, while simultaneously providing amazing fiber strength and / or minimizing or reducing damage to hair caused by chemical treatment. Therefore, another aspect of the disclosure relates to the methods of using any of the compositions disclosed herein to alter hair color, including lifting hair color and / or providing a desired hair color, while by improving the integrity of hair fibers and / or minimizing or reducing damage to hair caused by chemical treatment.

[0167] In various embodiments, the processes disclosed herein generally include applying to the hair an effective amount of a hair color-modifying composition disclosed herein. The hair color-modifying composition is generally obtained at or near the time of use by mixing a hair color-modifying base composition disclosed herein and a developer composition comprising at least one oxidizing agent. In some embodiments, the processes may further include mixing a hair color-modifying base composition disclosed herein and a developer composition described herein at or near the time of use.

[0168] In various embodiments, prior to the application of the compositions disclosed herein, the hair may be bleached, shampooed, and / or rinsed. In some embodiments, before applying the hair-color-modifying composition, the hair may first be washed with a commercial shampoo or rinsed with water. The hair may further be conditioned and / or rinsed after shampooing and before applying the compositions disclosed herein. Once the hair has been washed, conditioned, and / or rinsed, the hair-color-modifying composition is then applied to the washed or rinsed hair while the hair is wet, damp, or moist.In some other embodiments, before applying the hair-color-modifying composition, the hair may be moistened, dampened, or wetted with sprayed water or a damp towel, or by applying other treatment compositions that render the hair moist, damp, or wet. In some embodiments, after applying the disclosed compositions to the hair, the hair may be rinsed, washed, and / or conditioned once or more.

[0169] As used herein, the term "effective amount" refers to any quantity sufficient to provide a desired enhancing or coloring effect. For example, in some embodiments, from about 0.1 g to about 50 g of a hair-color-modifying composition may be applied to the hair, depending on the specific product formulation, hair length, hair volume, and hair color. In some embodiments, about 0.1 gram (g) of the composition per gram of hair is applied to the hair. In some embodiments, about 0.5 gram (g) of the composition per gram of hair is applied to the hair. The composition applied to the hair may be distributed as needed, e.g., massaged in. regularly or evenly over all of the hair by combing with the fingers or a means such as a comb or other.

[0170] Once the hair color-modifying composition is applied to the hair, the composition can remain on the hair for a sufficient period to impart the benefits of the composition (“leave-in period”), such as the enhancing effect or the delivery of the desired color or shade to the hair. For example, the coloring composition can be left on the hair for up to one hour, e.g., from about 1 minute to about 60 minutes, from about 1 minute to about 45 minutes, from about 1 minute to about 30 minutes, from about 1 minute at approximately 20 minutes, from approximately 1 minute to approximately 15 minutes, from approximately 1 minute approximately 10 minutes, approximately 1 minute to approximately 5 minutes, approximately 3 minutes approximately 45 minutes, approximately 5 minutes to approximately 30 minutes, or approximately 10 Leave on for approximately 20 to 30 minutes, then rinse from the hair. A person skilled in the art, taking into account various factors such as the starting hair color and the desired color, can determine an appropriate time to leave the hair color-modifying composition or mixture on the hair to achieve the desired color change. If desired, hair to which color mixtures have been applied can also be shampooed and / or conditioned after rinsing.

[0171] In some embodiments, a process disclosed herein is intended to color or dye hair permanently, while improving the strength and integrity of the hair fibers. In this case, a base composition modifying hair color may include one or more coloring agents such as oxidative dyes optionally combined with one or more couplers.

[0172] After describing in detail the numerous embodiments of the present invention, it will be evident that modifications and variations are possible without departing from the scope of the disclosure defined in the attached claims. Furthermore, it should be noted that all the examples in this disclosure, while illustrating numerous embodiments of the disclosure, are provided by way of non-limiting examples and should therefore not be considered as limiting the various aspects thus illustrated. It should be understood that all definitions herein are provided solely for the purposes of this disclosure.

[0173] As used herein, the terms "comprising," "having," and "including" (or "comprise," "having," and "include") are used in their broad, non-limiting sense. The expression "consisting essentially of" limits the scope of a claim to the specified materials or steps and to those that do not materially affect the fundamental and innovative feature(s) of the compositions.

[0174] The expression "one or more" means "at least one" and therefore includes individual components as well as mixtures / combinations. Similarly, the expression "a salt of it" also refers to "salts of it." Thus, when the disclosure refers to "a selected element from the group consisting of A, B, C, D, E, F, a salt of these, or a mixture of these," it indicates that one or more of A, B, C, D, and F may be included, one or more of a salt of A, a salt of B, a salt of C, a salt of D, a salt of E, and a salt of F may be included, or a mixture of any two of A, B, C, D, E, F, a salt of A, a salt of B, a salt of C, a salt of D, a salt of E, and a salt of F may be included.

[0175] The expression "and / or" should be understood as including both the conjunctive and the disjunctive. For example, "citric acid and / or its salts" means "citric acid and its salts" as well as "citric acid or its salts", and expressly covers cases without reference to the other.

[0176] As used herein, the expressions “and mixtures thereof,” “and a mixture of these,” “and a combination of these,” “or mixtures of these,” “or a mixture of these,” “or combinations of these,” and “or a combination of these” are used interchangeably to indicate that the list of components immediately preceding the phrase, such as “A, B, C, D, or mixtures of these,” means that the component(s) may be chosen from A, B, C, D, from A + B, from A + B + C, from A + D, from A + C + D, etc., without limitation on the variations thereof. Thus, the components may be used individually or in any combination thereof.

[0177] For the purposes of this disclosure, it should be noted that, for the sake of brevity, some of the quantitative expressions given herein are not qualified as "approximately". It is understood that, whether the term "approximately" is used explicitly or implicitly, each quantity given herein is intended to refer to the actual value given, and is also intended to refer to the approximation of that value given that would be reasonably deduced on the basis of ordinary competence in the art, including approximations due to experimental and / or measurement conditions for that value given.

[0178] All ranges and quantities stated herein are deemed to include subranges and quantities using any disclosed point as a bound, and all bounds are deemed to be inclusive unless expressly stated otherwise. Thus, a range of "1% to 10%, such as 2% to 8%, such as 3% to 5%" is deemed to encompass ranges of "1% to 8%", "1% to 5%", "2% to 10%", and so on. All numbers, quantities, ranges, etc., are deemed to be modified by the term "approximately", whether or not expressly stated, unless expressly stated otherwise. Similarly, a given range of "approximately 1% to 10%" is deemed to have its bounds both of 1% and 10% modified by the term "approximately". The term "approximately" is used here to indicate a difference of up to + / - 10% of the stated number, such as + / - 9%, + / - 8%, + / - 7%, + / - 6%, + / - 5%, + / - 4%, + / - 3%, + / - 2%, or + / - 1%. Similarly, all range bounds are understood to be disclosed individually, so that, for example, a range of 1:2 to 2:1 is understood to disclose a ratio of both 1:2 and 2:1.

[0179] As used here, if a component is described as being present "in an amount less than or equal to" a certain amount, it is expected that this component is in fact present in the composition, i.e., present in an amount greater than 0%.

[0180] All quantities indicated here are relative to the quantity of active material, unless otherwise stated.

[0181] All percentages, parts and ratios herein are based on the total weight of the compositions of the present invention, unless otherwise stated.

[0182] The term "color modification" or "color altering" as used here refers to enhancing or lightening hair color. It may also refer to dyeing or coloring hair or depositing color onto the hair. In some cases, it involves enhancing or lightening hair color while simultaneously depositing color onto the hair.

[0183] As used herein, the terms "apply a composition to keratin fibers" and "apply a composition to hair" and variations thereof are intended to refer to contact with keratin fibers, including hair, with at least one of the compositions of the disclosure, in any manner whatsoever. This can also mean bringing the keratin fibers into contact in an effective amount of the composition.

[0184] As used herein, "cosmetic composition" encompasses many types of compositions for application to keratinous materials such as skin or hair, for example, hair lotions, hair creams, hair cream gels, hair conditioners, hair masks, etc., which may be used as treatments or leave-in or rinse-out products.

[0185] As used here, the term "inorganic" refers to a material that does not contain carbon.

[0186] As used here, the term "organic" refers to material that is produced substantially without or essentially without the use of synthetic materials.

[0187] As used here, the term "salts" may include salts containing a counterion such as an alkali metal, an alkaline earth metal, or an ammonium counterion. This list of counterions, however, is not exhaustive. Salts also include a dissociated form of a compound, for example, in an aqueous solution.

[0188] Linking agents should be understood to include salts of those agents, whether specifically stated or not. Thus, a "first linking agent selected from citric acid" should be understood to include salts of citric acid. Similarly, a "second linking agent selected from glycine" should be understood to include salts of glycine.

[0189] As used here, the term "stable" refers to the fact that the composition does not exhibit phase separation and / or crystallization for a period of time, e.g., for at least 1 day (24 hours), one week, one month, one year or two years.

[0190] As used herein, the terms "substantially free" or "essentially free" mean that the specific material may be present in small amounts that do not materially affect the fundamental and innovative characteristics of the compositions as disclosed. For example, there may be less than 2% by weight of a specific material added to a composition, relative to the total weight of the compositions (provided that an amount less than 2% by weight does not materially affect the fundamental and innovative characteristics of the compositions as disclosed). Similarly, the compositions may include less than 2%, less than 1.5%, less than 1%, less than 0.5%, less than 0.1%, less than 0.05%, or less than 0.01%, or none of the specified material.Furthermore, all components positively presented in this disclosure may be negatively excluded from the claims; for example, a claimed composition may be "free," "substantially free," or "significantly free" of one or more components that are positively presented in this disclosure. The terms "free," "significantly free," and "essentially free" as used herein may also mean that the specific material is not added to the composition but may still be present in a raw material included in the composition. For example, a composition according to the disclosure may not include an added wax but may include a pigment coated with a wax that may still be considered "free," "significantly free," or "essentially free" of waxes.

[0191] As used herein, the term "surfactants", as well as any specifically identified surfactant, includes salts of surfactants, even if not explicitly stated.

[0192] As used herein, the term "synthetic" means a material that is not of natural origin. The terms "natural" and "of natural origin" mean a material of natural origin, such as derived from plants, which cannot be subsequently altered chemically or physically. "Of plant origin" means that the material comes from a plant.

[0193] The term "treat" (and its grammatical variations) is used here to refer to the application of the compositions of this disclosure to the surface of keratinous substrates such as hair.

[0194] Unless expressly stated otherwise, no process described herein is intended to be interpreted as requiring that its steps be performed in a specific order. Accordingly, where a process claim does not expressly cite an order to be followed for its steps, or where it is not specifically indicated in the claims or descriptions that the steps must be limited to a specific order, no particular order is intended to be inferred from it.

[0199] As shown in Table 1, compositions IA and IB both include citric acid and glycine in a weight ratio of approximately 1:2.5 (citric acid to glycine). Compositions C1 and C2 include citric acid, respectively. and glycine in a weight ratio of 1:5 or 1:1 (citric acid to glycine). Compositions C3 and C4, while including taurine, do not include glycine. Composition C5 does not include any binding agent.

[0200] It should be noted that the exemplary compositions above are clear compositions, which can be added with one or more oxidative base dyes and / or couplers and formulated as compositions to impart colour effects to hair. By way of example, compositions incorporating one or more oxidative dyes such as hydroxybenzomorpholine, 2,4-diaminophenoxyethanol HCl, toluene-2,5-diamine (and) thioglycerin, resorcinol and / or m-aminophenol, in individual amounts ranging from about 0.003% to about 0.9% by weight, relative to the total amount of the composition, have also been prepared on the basis of formulations IA and IB. Example 2 - Developer compositions

[0201] An example of a 10V D developer composition shown in Table 2 was prepared. The developer had a pH at 25°C of approximately 2.2 (± 0.2).

[0203] Example 3 - Evaluation of the integrity of treated hair fibers

[0204] The integrity of the fibers of pre-bleached hair treated with the compositions inventives IA and IB was evaluated in comparison to pre-bleached hair treated with compositions C1-C5 and control pre-bleached hair via breaking stress tests (tensile test).

[0205] 1. Preparation of treated hair

[0206] Caucasian hair braids with an HT level of 4-5 were used in the tests. Each braid had 50 individual fibers and weighed approximately 2.7 g for a length of approximately 8". The hair braids were bleached once with a standard bleaching composition for approximately 50 minutes at 33#C. After bleaching, the hair braids were rinsed and washed once with a standard shampoo, then blow-dried for 2 minutes. At or near the time of use, compositions IA, IB, and C1-C5 were mixed with the 10V D developer from Example 2 in a 1:1 mixing ratio to prepare the hair color-modifying compositions 1A+D, 1B+D, Cl+D, C2+D, C3+D, C4+D, and C5+D. Each resulting mixture was applied to a separate, pre-bleached braid in a 10:1 UA bath ratio and left on the hair for treatment for approximately 20 minutes before rinsing. The application process was repeated up to seven times. Each braid was washed and blow-dried for approximately 2 minutes, or until completely dry, between applications and after the final application.The entire process was carried out at a temperature of approximately 27°C on an open-air plate (without using foils). Each mixture was tested in duplicate on separate, bleached braids. As a baseline control, two separate bleached braids were shampooed seven times and blow-dried for approximately 2 minutes between shampoos and after the final shampoo, without the application of any hair-color-altering compositions.

[0207] After the first, fourth, and / or seventh application of the mixtures, the hair braids were subjected to breaking stress tests to assess hair integrity. If statistically significant differences were observed after the first or fourth application, further applications might not be necessary.

[0208] Breaking stress tests

[0209] The breaking strength of the treated braids was measured using a miniature tensile testing apparatus (MTT-US1.3) at a tensile speed of approximately 10 mm / min when the hair braids were in the wet state after equilibration at room temperature and 80% relative humidity. The measured breaking strength of the hair after the fourth application was statistically analyzed using version 3.0.2 of the R software, where the level of statistical significance was set at p < 0.05. The statistical results are summarized in Table 3 and illustrated in [Fig. 1]. Breaking strength represents the force / area required to break the hair fiber. A higher breaking strength indicates a stronger and stiffer hair fiber.

[0211] * CI: confidence interval estimate

[0212] ** CV: coefficient of variation

[0213] As shown in Table 3 and [Fig. 1], the color-modifying process of pre-bleached hair using compositions without bonding agents (C5+D) resulted in a significant decrease in the hair's breaking strength value, indicating that the hair was weaker and more damaged compared to hair not treated with a color-modifying composition (baseline control). Conversely, as shown in [Fig. 1] and Table 3, hair treated with the 1A+D or 1B+D mixtures, which include a bonding system according to disclosure, surprisingly demonstrated a statistically significant improvement in breaking strength value compared to hair treated with the C5+D mixture (p < 0.05).This result demonstrates that hair treated with compositions as disclosed exhibited greater fiber integrity and strength, and less damage, even after undergoing a hair color modification process, compared to hair subjected to the same process but without the beneficial bonding agents as disclosed.

[0214] The results also show that the breaking strength values ​​of hair treated with the Cl+D, C2+D, C3+D, or C4+D mixture, which included bonding agents but not as disclosed, were not statistically improved compared to the breaking strength of hair treated with the C5+D mixture (p > 0.05). This result demonstrates that hair treated with compositions as disclosed exhibited greater fiber integrity and strength, and less damage, even after undergoing a hair color modification process, compared to hair subjected to the same process but without the synergistic combination of bonding agents as disclosed.

[0215] The above data have demonstrated that the synergistic combination included in the claimed bonding system, together with other components of an oxidative system disclosed herein, when applied to hair in the presence of an oxidizing agent, unexpectedly confers a statistically significant improvement in hair integrity and minimizes additional damage to hair due to the hair color modification process.

[0216] It will be apparent to those skilled in the art that various modifications and variations can be made to the compositions and processes of the invention without departing from the spirit or scope of the disclosure. It is therefore intended that the disclosure will cover these modifications and variations as well as their equivalents.
