Description

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

[0001] This disclosure relates to compositions for modifying hair color and methods of using compositions for modifying hair color, while improving the integrity of hair fibers. CONTEXT

[0002] It is known that consumers wish to use cosmetic and care compositions that improve 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 revitalization. Many of the compositions and processes known to improve the appearance of hair involve chemical treatment of the hair.

[0003] The hair color modification process, for example, may involve enhancing the hair color and / or 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. Such 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] Imparting a color change or color effect to hair can be achieved using permanent, semi-permanent, or temporary hair coloring products. Conventional permanent hair coloring products are colorant compositions comprising oxidation colorant precursors, which are also known as primary intermediates or couplers. These oxidation colorant precursors are colorless or faintly colored compounds that, when combined with oxidizing agents, give rise to colored complexes through an oxidative condensation process. Oxidizing agents traditionally use peroxides such as hydrogen peroxide.

[0005] On the other hand, semi-permanent or temporary hair coloring compositions typically use pigments, liposoluble colorants, or direct colorants chosen from among acidic (anionic), basic direct colorants (cationic) or neutral dyes 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 hair color, resisting several shampooings. These dyes may or may not be used in the presence of an oxidizing agent. Unlike oxidation dye precursors, a direct dye is a relatively large molecule that does not easily penetrate the center of the hair fiber.

[0006] Hair lightening or color-enhancing compositions and hair coloring compositions possess an alkalinity such that these compositions have a pH value greater than 7, typically greater than or equal to 9, and may generally require the presence of ammonia or an ammonia-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 oxidizing dye to penetrate the cuticle and cortex before the completion of the oxidative 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 aggressive and can damage hair fibers and reduce hair strength, and can also negatively affect sensory properties, such as softness, shine, and feel of the hair. Furthermore, hair damaged during a bleaching and / or coloring 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 new combinations of ingredients that can promote the prevention, improvement, or repair of damage before, during, or after hair color modification processes, or as a complement to them, 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 the ease and uniformity of application, the rheology 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 cause further drawbacks such as increased damage or a less healthy appearance of the hair.

[0009] In this regard, it is necessary to develop new and improved products that can be used to effectively alter hair color, while maintaining or improving hair integrity during coloring and avoiding or minimizing hair damage. This disclosure addresses these concerns and needs and relates to hair color-modifying compositions incorporated with bonding agents to maintain and / or improve the integrity of chemically treated and / or damaged hair during hair color modification.

III. Methods

[0161] The compositions described herein can effectively alter hair color, while providing surprising fiber strength and / or minimizing or reducing hair damage caused by chemical treatment. Therefore, another aspect of the disclosure relates to methods of using any of the compositions disclosed herein to alter hair color, including enhancing hair color and / or providing a desired hair color, while improving hair fiber integrity and / or minimizing or reducing hair damage caused by chemical treatment.

[0162] In various embodiments, the methods 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 methods may further include mixing a hair color-modifying base composition disclosed in this document and of a developer composition described in this document at or near the time of use.

[0163] In various embodiments, prior to the application of the compositions disclosed herein, the hair may be bleached, shampooed, and / or rinsed. In some embodiments, prior to the application of the hair-color-modifying composition, the hair may first be cleansed with a commercially available shampoo or rinsed with water. The hair may further be conditioned and / or rinsed after shampooing and prior to the application of the compositions disclosed herein. After the hair has been shampooed, conditioned, and / or rinsed, the hair-color-modifying composition is applied to the washed or rinsed hair while it is wet, damp, or slightly damp.In some other embodiments, before applying the hair-color-modifying composition to the hair, the hair may optionally be lightly dampened, moistened, or wetted with a water spray or a damp towel, or by applying other treatment compositions that render the hair slightly damp, moist, or wet. In some embodiments, after applying the disclosed compositions to the hair, the hair may further be rinsed, washed with a shampoo, and / or conditioned once or several times.

[0164] 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 gram to about 50 grams of a hair-color-modifying composition may be applied to the hair, depending on the specific formulation of the product, the 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 required, e.g., massaged substantially evenly or uniformly over all the hair by combing with the fingers or a means such as a comb or other tool.

[0165] After the hair color modifying composition has been applied to the hair, the composition may remain on the hair for a sufficient period to confer the benefits provided by the composition (“application period”), such as enhancing the hair color or providing the desired color or shade. For example, the coloring composition may 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 for approximately 20 minutes, from approximately 1 minute to approximately 15 minutes, from approximately 1 minute to approximately 10 minutes, from approximately 1 minute to approximately 5 minutes, from approximately 3 minutes to approximately 45 minutes, from approximately 5 minutes to approximately 30 minutes, or from approximately 10 minutes to approximately 20 minutes, and then rinsed out of the hair. A person skilled in the art can, by considering various factors such as the initial hair color and the desired color, determine an appropriate time to leave the hair color-modifying composition or mixture on the hair to achieve the desired hair color change. If desired, hair to which color mixtures have been applied can further be washed with shampoo and / or conditioned after the color mixtures have been rinsed out of the hair.

[0166] In some embodiments, a method disclosed herein is for permanently coloring or dyeing hair, 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.

[0167] After describing in detail the numerous embodiments of the present invention, it will become 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 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 is understood that all definitions in this document are provided solely for the purposes of this disclosure.

[0168] As used herein, the terms "comprising," "having," and "including" (or "comprise," "having," and "include") are used in their broad, non-limiting sense. The expression "being essentially made of" limits the scope of a claim to the specified materials or stages and to those that do not materially affect the basic and novel characteristics of the compositions.

[0169] 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 "an element selected from the group consisting of A, B, C, D, E, F, a salt of these, or mixtures 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.

[0170] 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 one of the cases without reference to the other.

[0171] 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.

[0172] For the purposes of this disclosure, it should be noted that, to provide a more concise description, some of the quantitative expressions given in this document are not qualified by the term "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.

[0173] All ranges and quantities stated 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 ranges of "1% to 8%", "1% to 5%", "2% to 10%", and so on. All numbers, quantities, ranges, etc., are intended 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 intended to have its boundaries of both 1% and 10% modified by the term "approximately". The term "approximately" is used here to indicate a difference of up to + / - 10% from the stated number, such as + / - 9%, + / - 8%, + / - 7%, + / - 6%, + / - 5%, + / - 4%, + / - 3%, + / - 2%, or + / - 1%.Similarly, all range boundaries are understood as being disclosed individually, such that, for example, a range of 1:2 to 2:1 is understood as disclosing a ratio of 1:2 and 2:1.

[0174] 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 either actually present in the composition, namely present in a quantity greater than 0%.

[0175] All quantities indicated herein are relative to the quantity of active material, unless otherwise stated.

[0176] All percentages, parts and ratios herein are based on the total weight of the compositions in this disclosure, unless otherwise stated.

[0177] The term "color modification," 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.

[0178] As used herein, the terms "apply a composition to keratin fibers" and "apply a composition to hair," and variations thereof, are intended to denote the contact of keratin fibers, including hair, with at least one of the compositions in the disclosure, in any manner whatsoever. This may also mean the contact of keratin fibers with an effective amount of the composition.

[0179] As used here, a "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 treatments or leave-in or rinse-out products.

[0180] As used here, the term "inorganic" refers to a material that does not contain carbon.

[0181] As used here, the term "organic" means a material that is produced substantially without or essentially without the use of synthetic materials.

[0182] 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.

[0183] The term "binding agents" shall be understood to include salts of such agents, whether specifically indicated or not. Thus, a "first binding agent selected from citric acid" shall be understood to include salts of citric acid. Similarly, a "second binding agent selected from glycine" shall be understood to include salts of glycine.

[0184] As used here, the term "stable" refers to the fact that the composition does not exhibit phase separation and / or crystallization over a period of time, for example, of at least 1 day (24 hours), a week, a month, a year or two years.

[0185] 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 basic and novel characteristics of the compositions as disclosed.

[0200] Example 4 - Differential scanning calorimetry measurement of treated hair

[0201] The performance of compositions IA to IJ in Table 1 was evaluated using differential scanning calorimetry, by measuring the denaturation temperature of the hair, compared to the comparative compositions Cl and C2, and to untreated control hair. The objective of using this technique was to evaluate the intensity of the binding benefit of the active materials on the hair.

[0202] Differential scanning calorimetry (DSC) measures the energy transferred to or from a sample subjected to a physical or chemical change. It is useful for studying the structural characteristics of hair fibers. Keratin undergoes detectable transformations at different temperatures. Changes in these transformation temperatures can be used to estimate the impact of a particular hair treatment on the hair. In this case, DSC was used to measure the denaturation temperature (Td). The denaturation temperature (Td) was used as a representation of the thermal stability of hair fibers, which is influenced, at least in part, by the crosslinking density of the matrix (intermediate filament-associated proteins, IFAPs).The denaturation temperature (Td) and its relationship in determining the thermal stability of hair fibers are established in the scientific literature on the subject. Generally, the denaturation temperature of hair (α-keratin proteins) is higher if the resistance / integrity of the hair is high, and vice versa.

[0203] Experiments were carried out on strands of natural level 4 (NL4) hair, approximately 12 cm long and containing 50 fibers per strand. Before application, the hair strands were washed five times with shampoo and air-dried. At or near the time of use, the inventive and comparative compositions of Table 1 and Table 2 were respectively mixed with developer D of Table 3 in a mixing ratio of approximately 1:1, resulting in corresponding mixtures, namely compositions modifying the hair color of 1A+D, 1B+D, 1C+D, 1D+D, 1E+D, 1F+D, 1G+D, 1H+D, 1I+D, 1J+D, Cl+D and C2+D.

[0204] The same amount of each of the above mixtures was applied to a separate strand of hair that had been pre-washed with shampoo five times and air-dried. Each mixture applied to the hair was left 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.

[0205] To prepare the hair samples for DSC measurement, the colored hair prepared above was trimmed from the midsection and cut into finer particles (< 0.5 mm). The hair particles (hair samples) were weighed to approximately 7 mg to 8 mg and placed in a DSC chamber. Approximately 50 µL of deionized water (DI water) was added to the chamber, and the hair particles were soaked in the water. Four chambers were prepared for each composition (i.e., n = 4). The hair samples were equilibrated at room temperature and left overnight. The following day, i.e., approximately 24 hours after hair processing, the hair samples were analyzed on a Discovery 2500 series DSC instrument starting at 40 °C and ramping up at 10 °C / min to 180 °C.

[0206] The denaturation temperature results for the treated and control hair are illustrated in the graph in [Fig. 1]. As shown in [Fig. 1], compared to untreated hair, hair treated with the C2+D mixture, which contains hexadimethrin chloride and the cationic polymer polyquaternium-22, has a similar denaturation temperature to that of untreated hair. Hair treated with the Cl+D mixture, which does not include any binding agent disclosed here, or a cationic polymer, had a lower denaturation temperature, indicating that the hair was damaged or weakened due to the chemical treatment to alter hair color.In contrast, hair strands treated with developer D mixtures with compositions 1A-1J all showed statistically significantly improved denaturation temperatures, namely greater than 0.5 °C, compared to untreated hair and hair treated with mixtures Cl+D and C2+D. Furthermore, hair treated with developer D mixtures and compositions 1A-1J was neither greasy nor tangled and exhibited a marked improvement in feel and naturalness compared to hair treated with mixture C2+D, which contains cationic polymers.

[0207] The results demonstrate that the hair colour-altering compositions disclosed herein, which comprise a bonding system including citric acid, an amino acid and / or an aminosulfonic acid, such as glycine, arginine and / or taurine, when used to treat hair, have remarkably improved the strength and integrity of the hair. In addition, the compositions according to this disclosure do not include cationic polymers, and can therefore provide the hair with a better sensory and natural feel, compared to hair treated with a composition containing a cationic polymer.

[0208] It should be noted that the 1A-1J formulation examples are transparent base compositions. They can be added to any oxidizing colorant to form hair coloring compositions for coloring hair. According to the results above, such formulated coloring compositions would not damage the hair, but would improve the integrity of hair colored by these compositions.

[0209] Example 5 - Evaluation of fibre integrity by tensile testing

[0210] The integrity of the hair fibers treated with compositions 1A-1J, which include a binding agent such as citric acid, arginine, glycerin and / or taurine incorporated into a hair colour modifying composition, was evaluated by a pull test against hair treated with comparative compositions Cl and C2, as well as with untreated hair.

[0211] Breaking stress represents the force / surface area required to break the hair fiber. The modulus of elasticity represents a measure of the elastic structure (elasticity) of the hair. The modulus of elasticity provides information about fiber deformation, so fibers with a higher modulus of elasticity are more elastic (less brittle) and resistant to deformation. As used here, the term "tensile toughness" refers to a property indicating the resistance of the hair fiber to breakage when a crack or other stress-concentrating defect is present. To be tenacious, a hair fiber must be both strong and ductile. Tensile toughness is usually measured in units of Joules per cubic meter (J⁻¹T³) in the International System of Units (SI). The higher the tenacity, the greater the resistance to breakage.

[0212] Experiments were conducted on strands of natural virgin hair approximately 12 cm long and containing 50 fibers per strand. At or near the time of use, each of the compositions 1A-1J and the comparative compositions Cl and C2 were mixed with Developer D from Table 3 in a mixing ratio of approximately 1:1 at 27°C for approximately 35 minutes to obtain mixtures (compositions modifying hair color). To treat a 3 g strand of hair, approximately 4.5 g of each of compositions 1A-1J, Cl, and C2 were mixed with approximately 4.5 g of Developer D.

[0213] In a first test, the same quantity of each of the above mixtures was applied to a separate strand of hair that had been pre-washed with shampoo The hair was washed five times and air-dried before the mixtures were applied, with a mixing ratio of approximately 9 g of mixture to 3 g of hair. Each mixture was left on the hair for approximately 35 minutes at room temperature. The hair was then rinsed under running water for about 30 seconds and blow-dried for 30 seconds.

[0214] In a second test, the same quantity of each of the above mixtures was applied to a separate strand of hair that had been pre-washed with shampoo five times and air-dried before the mixtures were applied, where the bath ratio was approximately 9 g of one mixture to 3 g of hair. Each mixture applied to the hair was left on the hair for approximately 35 minutes at room temperature. The mixtures were then rinsed off, and the hair strands were washed once with shampoo. After shampooing, the treated hair strands were rinsed and blow-dried for 30 seconds.

[0215] Hair strands prepared as above and an untreated hair strand used as a control were allowed to equilibrate for 24 hours at 45% relative humidity and room temperature. They were then subjected to a tensile test using a Miniature Tensile Tester (MTT680 from Dia-Stron Ltd) when the hair strands were dry at a tensile speed of approximately 10 mm / min. The breaking strength, plateau stress, tensile toughness, and / or the modulus of elasticity (Young's modulus) of the treated 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 defined as p < 0.05.

[0216] The results show that compositions including a combination of citric acid and one or more amino acids such as arginine and / or glycine, and / or a sulfonic acid such as taurine, have surprisingly and significantly improved the breaking strength, plateau stress, tensile toughness and / or modulus of elasticity of the treated hair, compared with the comparative compositions.

[0217] The results demonstrate the synergistic effect provided by the bonding system disclosed in this document.

[0218] It will be obvious to those skilled in the art that various modifications and variations can be made to the compositions and methods according to the disclosure 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.
