Description

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

[0001] The present disclosure relates to compositions for modifying hair color and methods of using the compositions to modify hair color, while at the same time strengthening the integrity of hair fibers. BACKGROUND

[0002] It is known that consumers desire to use cosmetic compositions to enhance the appearance of keratinous substrates such as hair, for example, by altering 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 for improving the appearance of hair involve chemical treatment of the hair.

[0003] For example, the process of changing hair color may involve, for example, enhancing the hair color and / or depositing an artificial color onto the hair, which provides a different shade or color to the hair. The process of enhancing hair color, 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, thereby 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, demi-permanent, semi-permanent, or temporary hair coloring products. Conventional permanent hair coloring products are dye 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 products, give rise to colored complexes through an oxidative condensation process. Oxidizing products usually use peroxides such as hydrogen peroxide as oxidizing agents.

[0005] On the other hand, semi-permanent or temporary hair dye compositions usually use pigments, fat-soluble dyes or direct dyes chosen from acidic (anionic), basic (cationic) or neutral direct dyes which are deposited on the hair fiber to impart color to 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 color of the hair, resistant to several shampoos. These dyes can be used with or without an oxidizing agent. Unlike oxidation dye precursors, a direct dye is a relatively large molecule that does not easily penetrate the core of the fiber.

[0006] Hair lightening or color enhancing compositions and hair dye compositions possess alkalinity such that these compositions have a pH value greater than 7, usually 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 amounts to render these compositions alkaline. These alkalizing agents cause the hair shaft to swell, help open the cuticle, thereby allowing small oxidative dye molecules to penetrate the cuticle and cortex before the oxidative condensation process is complete. The larger color complexes resulting from the oxidative reaction are then trapped within the hair fiber, thereby permanently changing the color of the hair.

[0007] Although such compositions can effectively modify the color of the hair, these chemical treatments with the use of these compositions are harsh and can damage the hair fibers and decrease the strength of the hair, and can also negatively affect the sensory properties, such as the smoothness, shine and feel of the hair. In addition, hair damaged during a bleaching and / or dyeing process may not absorb the color satisfactorily, resulting in unevenness or non-uniformity of the color.

[0008] Thus, in order to reduce or avoid these disadvantages of hair color modification products and processes as described above, there is a continuous search for new additional ingredients and new combinations of ingredients that can help prevent, improve, or reverse damage before, during, after, or in addition to hair color modification processes. Nevertheless, the choice of ingredients or combinations of ingredients could pose difficulties insofar as they cannot detract from other cosmetic attributes such as ease and uniformity of application, rheology or viscosity properties of the compositions, stability of the compositions, and / or color deposition and formation of a target shade, and they cannot further cause disadvantages 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 which exhibit desirable rheology properties and can be used to effectively modify hair color, while maintaining or improving hair integrity during coloring and avoiding or minimizing hair damage. The present disclosure addresses these concerns and needs and relates to hair color modifying compositions incorporating bonding actives to maintain and / or enhance the integrity of chemically treated hair and / or damaged hair during hair color modification.

For example, the hair coloring composition may be allowed to remain on the hair for up to one hour, such as 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 to about 20 minutes, from about 1 minute to about 15 minutes, from about 1 minute to about 10 minutes, from about 1 minute to about 5 minutes, from about 3 minutes to about 45 minutes, from about 5 minutes to about 30 minutes, or from about 10 minutes to about 20 minutes, and then rinsed from the hair.The skilled person will be able, taking into account various factors such as the starting hair color and the desired color to be achieved, to determine an appropriate duration of time for the hair color modifying composition or mixture to be left on the hair in order to achieve the desired hair color alternative. If desired, the hair to which coloring mixtures are applied may further be shampooed and / or conditioned after rinsing the coloring mixtures from the hair.

[0173] In some embodiments, a method disclosed herein is for permanently coloring or dyeing hair, while improving the strength and integrity of hair fibers. In this case, a hair color modifying base composition may include one or more coloring agents such as oxidation dyes optionally combined with one or more couplers.

[0174] Having described in detail the numerous embodiments of the present invention, it will be apparent that modifications and variations are possible without departing from the scope of the disclosure defined in the appended claims. Furthermore, it should be noted that all examples of the present disclosure, while illustrating numerous embodiments of the disclosure, are provided by way of non-limiting examples and therefore should not be construed as limiting the various aspects thus illustrated. It should be understood that all definitions are provided herein only for the purposes of this disclosure.

[0175] As used herein, the terms "comprising", "having" and "including" (or "comprise", "have" and "include") are used in their broad, non-limiting sense. The expression "consisting essentially of" limits the scope of a claim to specified materials or steps and to those which do not materially affect the fundamental and novel feature(s) of the compositions.

[0176] In the present application, the use of the singular includes the plural, unless specifically indicated otherwise. The singular forms "a", "an", "the", "the" and "at least one" are understood to encompass the plural as well as the singular, unless the context clearly dictates otherwise. The expression "one or more" means "at least one" and therefore includes individual components as well as mixtures / combinations. Similarly, the expression "a salt thereof" also refers to "salts thereof".Thus, when the disclosure refers to "an element selected from the group consisting of A, B, C, D, E, F, a salt thereof, or a mixture thereof," 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.

[0177] The expression "and / or" is to be understood as including both the conjunctive and the disjunctive. For example, "a lactic acid and / or salts thereof" means "a lactic acid and salts thereof" as well as "a lactic acid or salts thereof", and expressly covers examples of one of the two without reference to the other.

[0178] As used herein, the phrases "and mixtures thereof," "and a mixture thereof," "and a combination thereof," "or mixtures thereof," "or a mixture thereof," "or combinations thereof," and "or a combination thereof," are used interchangeably to indicate that the list of components immediately preceding the phrase, such as "A, B, C, D, or mixtures thereof," means that the component(s) may be selected from A, B, C, D, from A + B, from A + B + C, from A + D, from A + C + D, etc., without limitation on variations thereof. Thus, the components may be used individually or in any combination thereof.

[0179] For the purposes of this disclosure, it should be noted that, to provide a more concise description, some of the quantitative expressions provided herein are not qualified with the term "about." It is understood that, whether the term "about" is used explicitly or not, each quantity given herein is intended to refer to the actual value given, and it is also intended to refer to the approximation to that given value that would be reasonably inferred based on ordinary skill in the art, including approximations due to experimental and / or measurement conditions for that given value.

[0180] All ranges and quantities set forth herein are intended to include subranges and quantities using any disclosed point as a boundary, and all boundaries are intended 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 intended to encompass the ranges of “1% to 8%,” “1% to 5%,” “2% to 10%,” etc. All numbers, quantities, ranges, etc. are intended to be modified by the term “about,” whether or not expressly stated, unless expressly stated otherwise. Similarly, a given range of “about 1% to 10%” is intended to have both its 1% and 10% boundaries modified by the term “about.” The term "approximately" is used herein 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 boundaries are understood to be individually disclosed, 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.

[0181] As used herein, if a component is described as being present "in an amount up to" a certain amount, that component is actually intended to be present in the composition, i.e., is present in an amount greater than 0%.

[0182] All quantities stated herein are relative to the amount of active ingredient unless otherwise stated.

[0183] All percentages, parts and ratios herein are based on the total weight of the compositions of the present disclosure, unless otherwise indicated.

[0184] The term "color modification" or "color altering" as used herein refers to enhancing or lightening the color of hair. It may also refer to dyeing or coloring hair or depositing color on hair. In some cases, it refers to enhancing or lightening the color of hair while depositing color on the hair.

[0185] As used herein, the phrases "applying a composition to keratin fibers" and "applying a composition to hair" and variations thereof are intended to mean contacting keratin fibers, including hair, with at least one of the compositions of the disclosure, in any manner. It may also mean contacting the keratin fibers with an effective amount of the composition.

[0186] As used herein, "cosmetic composition" encompasses many types of compositions for application to keratinous materials such as skin or hair, e.g., hair lotions, hair creams, hair cream gels, hair conditioners, hair masks, etc., which may be used as leave-in or rinse-out treatments or products.

[0187] As used herein, the term "inorganic" means a material that does not include of carbon.

[0188] As used herein, the term "organic" refers to a material that is produced substantially without or essentially without the use of synthetic materials.

[0189] As used herein, the term "salts" may include salts having a counterion such as an alkali metal, an alkaline earth metal, or an ammonium counterion. This list of counterions is, however, not limiting. Salts also include a dissociated form of a compound, for example, in an aqueous solution.

[0190] Linking agents are to be understood to include salts of such agents, whether or not explicitly stated. Thus, a "first linking agent selected from lactic acid" is to be understood to include salts of lactic acid. Similarly, a "second linking agent selected from glycine" is to be understood to include salts of glycine.

[0191] As used herein, the term "stable" refers to the composition not exhibiting 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.

[0192] 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 novel characteristics of the compositions according to the disclosure. For example, there may be less than 2% by weight of a specific material added to a composition, based on the total weight of the compositions (provided that an amount less than 2% by weight does not materially affect the fundamental and novel characteristics of the compositions according to the disclosure). 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% of the specified material, or none at all.Additionally, any components positively presented in the present disclosure may be negatively excluded from the claims, e.g., a claimed composition may be "free," "substantially free," (or "substantially free") of one or more components that are positively presented in the present disclosure. The terms "free," "substantially free," and "substantially free" as used herein may also mean that the specific material is not added to the composition, but may still be present in a starting material included in the composition. For example, a composition according to the disclosure may not include an added wax, but may include a pigment that is coated with a wax and still be considered "free," "substantially free," or "substantially free" of waxes.

[0193] As used herein, the term "surfactants", as well as any surfactant specifically identified, includes salts of surfactants, even if not explicitly stated.

[0194] As used herein, the term "synthetic" means a material that is not naturally occurring. The terms "natural" and "naturally occurring" mean a material that is naturally occurring, such as derived from plants, and also cannot be subsequently chemically or physically altered. "Plant-derived" means that the material comes from a plant.

[0195] As used herein, the term "treat" (and its grammatical variations) refers to the application of the compositions of the present disclosure to the surface of keratinous materials such as hair.

[0196] Unless otherwise expressly stated, it is not intended that any method recited herein be construed as requiring that its steps be performed in any specific order. Accordingly, where a method claim does not expressly recited an order to be followed by its steps or it is not specifically stated in the claims or descriptions that the steps are to be limited to a specific order, it is in no way intended that any particular order be inferred. Examples

[0197] The following examples are intended to be non-limiting and purely explanatory in nature. In the examples, the amounts of each composition are expressed as a percentage by weight (% by weight) of active ingredients, unless otherwise defined, relative to the total weight of the composition.

[0198] Example 1 - Hair color modifying compositions

[0199] Exemplary base compositions 1A-1G according to the present disclosure and comparative compositions C1-C4 were prepared by mixing the components according to the formulations shown in Table 1.

[0201] The pH of each composition was from about 10 to about 11. All compositions were in the form of a cream and were stable for at least 48 hours after being prepared. Example 2 - Developer compositions

[0202] An exemplary 20V D developer cream composition shown in Table 2 was prepared. The developer had a pH at 25°C of about 2.2 (± 0.2).

[0204] Example 3 - Evaluation of the integrity of hair treated with compositions 1A-1F

[0205] The fiber integrity of hair treated with inventive compositions 1A-1F was evaluated by measuring the elastic modulus and tensile strength of the hair compared to hair treated with comparative compositions C1-C4.

[0206] The elastic modulus represents a measure of the spring-like structure (elasticity) of hair. The elastic modulus provides information about the deformation of the fibers, and thus, fibers with a higher elastic modulus are more resistant to deformation. As used herein, "tensile toughness" refers to a property indicating the resistance of the hair fiber to breaking when a crack or other stress concentration defect is present. For To be strong, a hair fiber must be both strong and ductile. Tensile toughness is usually measured in units of Joule per cubic meter (J-rm3) in the International System of Units (SI). The higher the tenacity, the higher the breaking strength.

[0207] Experiments were carried out on natural hair samples of about 12 cm length and 50 fibers per sample. At or near the time of application, the inventive compositions 1A-1F and comparative composition C1-C4 of Table 1 were mixed respectively with developer D of Table 2 in a mixing ratio of about 1:1, resulting in the corresponding mixtures, namely hair color modifying compositions 1A+D, 1B+D, 1C+D„, 1D+D, 1E+D, 1F+D, C1+D, C2+D, C3+D and C4+D.

[0208] The same amount of each of the above mixtures was applied to a separate hair sample that had been pre-washed with shampoo five times and air-dried. Each mixture applied to the hair was allowed to remain on the hair for approximately 35 minutes at room temperature. The hair was then rinsed under running water for approximately 30 seconds and blow-dried for 30 seconds.

[0209] The hair samples prepared as above and an untreated hair sample used as a control were allowed to equilibrate for 24 hours at 45% relative humidity and room temperature and then subjected to a tensile test using a miniature tensile tester (MTT680 from Dia-Stron Ltd) when the hair samples were in a dry state at a tensile speed of approximately 10 mm / min when the hair samples were in a dry state. The elastic modulus and tenacity of the hair were measured. The measurements obtained were statistically analyzed using a two-sample t-test assuming equal variances, where the level of statistical significance was set at p < 0.05.

[0210] The results of the elastic modulus of the above-treated hair samples are illustrated in [Fig.l]. As shown in [Fig.l], hair treated with mixtures C2+D, C3+D or C4+D, which only include lactic acid, arginine or glycine, and hair treated with mixture Cl+D, where no binding agent is included, did not show a significant difference in terms of elastic modulus. In contrast, hair treated with mixture 1A+D, 1B+D, 1C+D, 1D+D, 1E+D or 1F+D, which included lactic acid and arginine and / or glycine, showed a significantly higher elastic modulus than hair treated with mixture Cl+D. The results demonstrate that the inventive compositions, which include a synergistic combination of lactic acid and one or more amino acids such as arginine and / or glycine, significantly improved the deformation resistance of the fibers.

[0211] The tensile toughness results of the above-treated hair samples are shown in [Fig. 2]. As shown in [Fig. 2], hair treated with mixtures C2+D, C3+D, or C4+D, which included only lactic acid, arginine, or glycine, and hair treated with mixture Cl+D, where no binding agent is included, did not show a significant difference in toughness. In contrast, hair treated with mixture 1A+D, 1B+D, 1C+D, 1D+D, 1E+D, or 1F+D, which included lactic acid and arginine and / or glycine, showed significantly higher toughness than hair treated with mixture Cl+D. The results demonstrate that the inventive compositions, which include a synergistic combination of lactic acid and one or more amino acids such as arginine and / or glycine, significantly improved the breaking strength of the fibers.

[0212] Example 4 - Evaluation of the Integrity of Hair Treated with Composition IG

[0213] The fiber integrity of hair treated with the inventive composition IG, which comprises a binding system including lactic acid, arginine and glycerin in an amount ratio of about 1:3:1.5 (lactic acid:arginine:glycine) incorporated in a hair color modifying composition, was evaluated by means of a tensile test in comparison with hair treated with comparative composition Cl, where no binding agent is included.

[0214] 4.1 Hair treatment and evaluation of treated hair

[0215] Experiments were carried out on samples of natural virgin hair with a length of about 12 cm and 50 fibers per sample. The inventive composition 1G and the comparative composition Cl of Table 1 were respectively mixed at or near the time of application with the developer D of Table 3 in a mixing ratio of about 1:1 to obtain the mixtures (hair color modifying compositions) 1G+D and Cl+D.

[0216] In a first test, the same amount of each of the above 1G+D and Cl+D mixtures was applied to a separate hair sample which was pre-washed with shampoo five times and air-dried before applying the mixtures. The bath ratio of the 1G+D and Cl+D mixture respectively applied to the hair was approximately 9 g of each mixture to 3 g of hair. Each mixture applied to the hair was allowed to remain on the hair for approximately 35 minutes at room temperature. The hair was then rinsed under running water for approximately 30 seconds and dried with a hairdryer for 30 seconds.

[0217] In a second test, the same amount of each of the above 1G+D and Cl+d mixtures was applied to a separate hair sample that had been pre-washed with shampoo five times and air-dried before applying the mixtures. The bath ratio of the 1G+D and Cl+D mixtures respectively applied to the hair was of approximately 9 g of each mixture per 3 g of hair. Each mixture applied to the hair was allowed to remain on the hair for approximately 35 minutes at room temperature. The mixtures applied to the hair were then rinsed and the hair samples were washed once with shampoo. After shampooing, the treated hair was rinsed and dried with a hairdryer for 30 seconds.

[0218] The hair samples prepared as above and an untreated hair sample used as a control were allowed to equilibrate for 24 hours at 45% relative humidity and room temperature and then subjected to a tensile test using a miniature tensile tester (MTT680 from Dia-Stron Ltd) when the hair samples were in a dry state at a tensile speed of approximately 10 mm / min. The breaking stress, plateau stress, tensile toughness, and / or elastic modulus (Young's modulus) of the treated hair were measured. .The obtained measurements were statistically analyzed using a two-sample t-test assuming equal variances, where the level of statistical significance was set at p < 0.05.

[0219] Breaking stress represents the force / area required to break the hair fiber. A higher breaking stress represents a stronger and stiffer hair fiber. Elastic modulus represents a measure of the spring-like structure (elasticity) of the hair. A higher elastic modulus indicates that the hair is more elastic (less brittle). 4.2 Results

[0220] The results of the breaking stress, plateau stress, and elastic modulus of the treated hair in the first test are shown in Figures 3-5. [Fig. 3] illustrates the breaking stress of the treated hair, [Fig. 4] illustrates the plateau stress of the treated hair, and [Fig. 5] illustrates the elastic modulus of the treated hair. As shown in Figures 3, 4, and 5, the hair treated with the 1G+D mixture had statistically significantly higher breaking stress, plateau stress, and elastic modulus (p < 0.05), indicating that the hair treated with the 1G+D mixture was not brittle and could withstand higher stresses, compared to the hair treated with the Cl+D mixture.

[0221] The results of the elastic modulus and plateau stress of the treated hair in the second test are shown in Figures 6 and 7. As shown in [Fig.6] and [Fig.7], compared to the untreated hair, the hair treated with the comparative Cl+D mixture had a reduced elastic modulus and plateau stress, indicating that the hair treated with the Cl+D mixture was damaged and had impaired integrity due to the chemical treatment to change the hair color. In contrast, the hair treated with the mixture 1G+D did not show a decrease in elastic modulus compared to untreated hair and showed significantly improved plateau stress compared to untreated hair and hair treated with the Cl+D mixture.

[0222] The above results demonstrated that the binding system in the IG composition, which comprises lactic acid, arginine and glycine in a weight ratio of lactic acid to arginine and glycine of about 1:3:1.5, significantly improved the integrity of the hair fibers. The benefit provided by the IG composition also proved to be surprisingly long-lasting. The integrity was preserved even after the treated hair was shampooed at least one more time.

[0223] Example 5 - Evaluation of the integrity of hair treated with compositions IA and 1H

[0224] The integrity of hair fibers treated with the inventive compositions IA and 1H was evaluated by means of a tensile test (MTT test) in comparison with hair treated with the comparative composition C1, where no binding agent is included, in the same manner as described in Example 5 for testing the composition IG. The compositions IA and 1H comprise lactic acid and arginine in different amounts, the amount of lactic acid being less than the amount of arginine.

[0225] The results obtained showed that the hair treated with the mixtures 1A+D and 1H+D respectively had a surprisingly higher modulus of elasticity, plateau stress and breaking stress than the hair treated with Cl+D, indicating that the compositions IA and 1H improve the integrity of the fibers of the treated hair. Unexpectedly, the effect also lasted after the treated hair had been shampooed at least once.

[0226] It will be apparent to those skilled in the art that various modifications and variations may be made in the compositions and methods of the invention without departing from the spirit and scope of the disclosure. It is therefore intended that the disclosure cover such modifications and variations as well as their equivalents.
