Description

Title of the invention: HAIR TREATMENT COMPOSITION field of disclosure

[0001] The present disclosure relates to hair treatment compositions and methods of treating hair with the hair treatment compositions. BACKGROUND

[0002] Many consumers desire to use cosmetic and care compositions that 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 cosmetic properties to the hair, such as shine and conditioning. Many of the compositions and processes known for enhancing the appearance of hair involve chemical treatments to the hair.

[0003] The process of changing hair color, for example, may involve depositing an artificial color on the hair that gives it a different shade or color, and / or enhancing the hair color, such as lightening dark hair color to lighter shades. The process of enhancing hair color, also called lightening (or bleaching), generally requires the use of oxidizing agents. Hair lightening is typically assessed by the variation in the pitch before and after the application of a hair color-changing composition to the hair. This variation corresponds to the degree or level of lightening or enhancement. The notion of "tone" is based on the classification of natural shades, a tone separating each shade from the shade immediately following or preceding it, well known to hair professionals.Tone heights or levels can range from 1 (black) to 10 (light blonde), one unit corresponding to one tone; thus, the higher the number, the lighter the shade or the greater the degree of enhancement.

[0004] In general, hair lightening or color enhancing compositions and hair coloring or dyeing compositions possess an alkalinity such that these compositions have a pH value greater than 7, typically being at pH 9 and above, and may generally require the presence of an alkalizing agent such as ammonia or a gaseous ammonia generating compound and / or an amine or ammonium based compound in sufficient amounts to render these compositions alkaline. The alkalizing agent causes the hair shaft to swell, which allows small oxidative dye molecules to penetrate the cuticle and the cortex before the oxidation-condensation process is complete. The larger colored complexes resulting from the oxidative reaction are then trapped inside the hair fiber, permanently changing the hair color.

[0005] In addition, there are many techniques and compositions for styling or altering the shape of hair. For example, hair care products called "relaxers" or "straighteners" can straighten or straighten curly or kinky hair, including wavy hair. Straightening or relaxing the curls of very curly hair can increase the manageability and manageability of such hair. Compositions for permanently waving hair impart a curl or wave to otherwise straight hair. Various types of compositions can be applied to the hair to alter its shape and make it more manageable, such as alkaline and acidic compositions. Relaxing, straightening, perming, and / or waving can be applied in a hair salon by a professional or at home by the individual consumer.

[0006] Although dyeing or color enhancing compositions can effectively change the color of hair, and straightening, smoothing, perming, and waving compositions can effectively change the shape of hair, these chemical treatments can damage hair fibers and / or irritate the scalp. Thus, in order to reduce or avoid damage to the hair, as well as to improve the cosmetic performance of the compositions, the use of new and additional components and innovative ingredient combinations is continually sought.

[0007] However, the selection of components or combinations of ingredients can pose difficulties in that they may not detract from other cosmetic attributes such as ease and uniformity of application, rheology or viscosity properties and stability of the compositions, color deposition and formation of the target shade, and / or result in other disadvantages such as increased damage or a less healthy appearance of the hair. It would therefore be desirable to provide the consumer with compositions and methods that can chemically treat the hair while providing other cosmetic benefits such as shine, conditioning, fiber strength and / or a healthy appearance of the hair, but avoiding or minimizing damage to the hair.

[0008] Furthermore, natural and sensitized or chemically treated hair may contain several types of negatively charged moieties, for example, carboxylates (resulting from the hydrolysis of amino acids and thioester bonds) and / or sulfonates (resulting from the oxidation of disulfide bonds). These negatively charged moieties may degrade the cosmetic properties of the hair. In addition, when the hair is chemically treated or damaged, the disulfide bonds of the hair (disulfide links between two cysteine ​​units) can be reduced or broken, resulting in the formation of thiol and / or cysteic acid groups.

[0009] Thus, an objective of the disclosure is to provide novel compositions that can provide beneficial effects such as strengthening of the hair fiber, protection of the hair fibers from damage or other harm, enhanced properties such as softness, shine, conditioning, healthy appearance, while at the same time providing the desired cosmetic.

[0024] The hair treatment compositions of the present disclosure, in various embodiments, are part of a kit, e.g., a kit comprising one or more hair treatment compositions according to the present disclosure and one or more additional hair treatment compositions, each of the one or more hair treatment compositions (and each of the additional hair treatment compositions) being contained separately. For example, in some embodiments, the kits com take: (i) one or more hair treatment compositions according to the present disclosure; and (ii) one or more additional hair treatment compositions selected from hair cleansing compositions (shampoos), hair conditioning compositions (conditioners), and hair treatment compositions for chemically treating hair comprising one or more chemically active agents that chemically treat the hair.

[0025] The hair treatment compositions are particularly useful in methods of treating hair, for example, methods of restructuring, repairing, strengthening and / or protecting hair. These methods are suitable for repairing, minimizing, mitigating and / or compensating for damage caused to the hair by chemical treatments (e.g., bleaching, coloring, straightening, curling, etc.). The methods also relate to preventing, minimizing, mitigating and treating hair vulnerable to damage (or already damaged) by environmental factors (e.g., hard water, sun damage, chlorine, etc.) and to damage caused by styling the hair, for example, with heat (e.g., blow drying, hot irons, etc.).

[0026] The methods include applying one or more hair treatment compositions of the present disclosure to the hair. The one or more hair treatment compositions may be temporarily applied to the hair (e.g., applied for a period of about 1 hour or less and rinsed from the hair), or may be applied to the hair and left on the hair for a longer period of time before being rinsed from the hair (e.g., for about 2 minutes, 5 minutes, 10 minutes, 20 minutes, 30 minutes or more). In cases where the hair treatment composition is rinsed from the hair shortly after application (immediately after application or within 2, 5, 10, 20, 30 minutes or more) before styling the hair, the hair treatment composition is a "rinse-out" product.In some embodiments, the hair treatment compositions are applied to the hair and may remain on the hair indefinitely, e.g., they may remain on the hair without being rinsed out prior to styling the hair, i.e., the hair treatment composition is a "leave-in" product. The methods are particularly well-suited for application to chemically treated hair, hair to be chemically treated, damaged hair, and natural hair, e.g., to improve the strength, luster, shine, and / or elasticity of the hair, etc.

[0027] The hair treatment compositions of the present case are particularly advantageous because they can be a stand-alone product (used independently) or can be used in methods that combine the hair treatment compositions of the present disclosure with a separate hair treatment composition for chemically treating hair (i.e., a hair treatment composition comprising one or more chemically active agents that chemically treat hair). Non-limiting examples of hair treatment compositions for chemically treating hair include bleaching compositions, hair straightening or curling compositions, hair relaxing or texlaxing compositions, and the like. The hair treatment compositions of the present invention can be combined with (added to) one or more components of a hair treatment composition for chemically treating hair.For example, if the hair treatment composition for chemically treating hair is a bleaching composition, the hair treatment compositions of the present invention may be added to a developer component, may be added to a bleaching component, or may be combined with a mixture of the developer component and the bleaching component. Similarly, hair styling compositions (for perming, straightening, and / or smoothing hair) often require more than one component (e.g., a relaxer component, an activator component, a neutralizer component, etc.). The hair treatment compositions of the present disclosure may include one or more (or all) of these components.

[0028] As above, the hair treatment compositions of the instant disclosure may be used as a stand-alone product in a hair cleansing (shampooing) and optional conditioning routine, or may be combined with (added into) a hair cleanser (shampoo), a conditioner, or added into both a hair cleanser and a hair conditioner.

[0243] Viscosity measurements may be made, for example, using a Brooksfield viscosimeter / rheometer using an RV-3 disc spindle or an RV-5 disc spindle at a particular speed, for example, 5, 10, 15 and / or 20 rpm or using a Rheomat with an M4 spindle. For example, viscosity may be measured with a T-bar E spindle using a Helipath post mounted on the Brookfield DV-11+ Pro, with a rotational speed of 20 rpm. Stability

[0244] The hair treatment compositions are stable and homogeneous. In other words, the hair treatment compositions do not visually phase separate or develop sedimentation, and do not form visibly observable particles, e.g., the hair treatment composition remains stable for at least 1 week at room temperature; the hair treatment composition remains stable for at least 8 weeks at 4°C; and / or the hair treatment composition remains stable for at least 8 weeks at 45°C. Accordingly, the present disclosure relates to hair treatment compositions that remain visually homogeneous and free from visual phase separation and particle formation for at least 1 week, 4 weeks, and / or 8 weeks at room temperature.In addition, the present disclosure relates to hair treatment compositions that remain visually homogeneous and free from visual phase separation and particle formation for at least 1 week, 4 weeks and / or 8 weeks at 4°C. The present disclosure also relates to hair treatment compositions that remain visually homogeneous and free from visual phase separation and particle formation for at least 1 week, 4 weeks and / or 8 weeks at 45°C. Processes

[0245] The hair treatment compositions are particularly useful in hair treatment methods, for example, hair restructuring, repairing, strengthening and / or protecting methods. These methods are suitable for repairing, minimizing, mitigating and / or compensating for damage to the hair caused by chemical treatments (e.g., bleaching, coloring, straightening, curling, etc.). The methods also relate to preventing, minimizing, mitigating and treating hair vulnerable to damage (or already damaged) by environmental factors (e.g., hard water, sun damage, chlorine, etc.) and damage caused by styling the hair, for example, with heat (e.g., blow drying, flat irons). hot ironing, etc.)

[0246] The methods include applying one or more hair treatment compositions of the present disclosure to the hair. The one or more hair treatment compositions may be temporarily applied to the hair (e.g., applied for a period of about 1 hour or less and rinsed from the hair), or may be applied to the hair and left on the hair for a longer period of time before being rinsed from the hair (e.g., for about 2 minutes, 5 minutes, 10 minutes, 20 minutes, 30 minutes or more). In cases where the hair treatment composition is rinsed from the hair shortly after application (immediately after application or within 2, 5, 10, 20, 30 minutes or more) before styling the hair, the hair treatment composition is a "rinse-off" product.In some embodiments, the hair treatment compositions are applied to the hair and may remain on the hair indefinitely, e.g., they may remain on the hair without being rinsed out prior to styling the hair, i.e., the hair treatment composition is a "leave-in" product. The methods are particularly well-suited for application to chemically treated hair, hair to be chemically treated, damaged hair, and natural hair, e.g., to improve the strength, luster, shine, and / or elasticity of the hair, etc.

[0247] The hair treatment compositions of the present invention are particularly advantageous because they can be a stand-alone product (used independently) or can be used in methods that combine the hair treatment compositions of the present disclosure with a separate hair treatment composition for chemically treating hair (i.e., a hair treatment composition comprising one or more chemically active agents that chemically treat hair). Non-limiting examples of hair treatment compositions for chemically treating hair include bleaching compositions, hair straightening or curling compositions, hair relaxing or texlaxing compositions, and the like.The hair treatment compositions of the present invention may be combined with (added to) one or more components of a hair treatment composition for chemically treating hair, for example, if the hair treatment composition for chemically treating hair is a bleaching composition, the hair treatment compositions of the present invention may be added to a developer component, may be added to a bleaching component, or may be combined with a mixture of the developer component and the bleaching component. Similarly, hair styling compositions (for perming, . Hair straightening and / or smoothing) often require more than one component (e.g., a straightening component, an activating component, a neutralizing component, etc.). The hair treatment compositions of the present disclosure may include one or more (or all) of these components.

[0248] As above, the hair treatment compositions of the instant disclosure may be used as a stand-alone product in a hair cleansing (shampooing) and optional conditioning routine, or may be combined with (added into) a hair cleanser (shampoo), a conditioner, or added into both a hair cleanser and conditioner.

[0249] The present disclosure relates to methods of making the hair treatment compositions. The methods include combining: (a) both citric acid and citric acid salts in a weight ratio of 1:10 to about 10:1 (or any of the ratios described in the disclosure); (b) one or more surfactants (in the amounts and types described in the disclosure); and water (e.g., in the amounts described in the disclosure) to form a hair treatment composition according to the present disclosure. The citric acid and citric acid salts may be combined with each other before being added to the other components of the hair treatment composition or may be added / combined individually to the other components of the hair treatment composition.

[0250] In some cases, to achieve a desired pH, the methods may include adding one or more pH correcting compounds, e.g., to provide a pH of about 3 to about 10 (or any other pH value or range described herein).

[0251] The methods also optionally include the combination of (d) one or more fatty alcohols (in the amounts and types described in the disclosure); (e) one or more fatty compounds other than fatty alcohols (in the amounts and types described in the disclosure); (f) one or more water-soluble solvents (in the amounts and types described in the disclosure); (g) one or more non-ionic thickening polymers (in the amounts and types described in the disclosure); (h) one or more conditioning agents selected from cationic polymers, silicones, and mixtures thereof (in the amounts and types described in the disclosure); and / or (i) one or more miscellaneous ingredients (in the amounts and types described in the disclosure).

[0302] * Viscosity was measured with the T-bar E spindle using a Helipath post mounted on Brookfield DV-II+ Pro, with a rotation speed of 20 rpm. Example 2 (Fiber Integrity Test)

[0303] A study was conducted to evaluate the hair fiber integrity of hair treated with inventive composition D of Example 1. The study used two different hair types: (1) European medium brown, 9% bleached hair strands (3.0 g, 8'' length, 1'' width); and (2) curly multi-ethnic brown, 9% bleached hair strands (3.0 g, 8'' length, 1'' width). The hair strands were subjected to one of three different treatment protocols.

[0304] [Tables2] Treatment 1 Treatment 2 Treatment 3 Shampoo (1 application) Inventive Composition D (6 applications) Inventive Composition D, shampoo and conditioner (6 applications)

[0305] Treatment 1: 0.4 g of a standard shampoo was applied to strands of hair, massaged into the hair for 30 seconds, and then left on the hair for 30 seconds. After 30 seconds, the shampoo was rinsed from the hair. The process was repeated six times (i.e., treatment 1 was performed six times).

[0306] Treatment 2: 0.4 g of the inventive composition D was applied to strands of hair, massaged into the hair for 30 seconds, and then left on the hair for 30 seconds. After 30 seconds, the inventive composition was rinsed from the hair. The process was repeated six times (i.e., treatment 2 was carried out six times).

[0307] Treatment 3: 0.4 g of the inventive composition D was applied to strands of hair, massaged into the hair for 30 seconds, and then left on the hair for 30 seconds. After 30 seconds, the inventive composition D was rinsed from the hair. Then, 0.4 g of a standard shampoo was applied to the strands of hair, massaged into the hair for 30 seconds, and then left on the hair for 30 seconds. After 30 seconds, the shampoo was rinsed from the hair. After rinsing the shampoo, 0.4 g of a standard conditioner was applied to the strands of hair, and then massaged into the hair for 30 seconds. After 30 seconds, the conditioner was rinsed from the hair. The process was repeated six times (i.e., treatment 3 was carried out six times).

[0308] After being subjected to one of the three treatments described above, the hair strands were dried for 2 minutes using a hair dryer set to medium heat. The hair fibers were periodically separated with the fingers during drying. After being dried, the hair strands were stored at 60% relative humidity (60%) overnight.

[0309] After being stored overnight, hair fibers were randomly selected from each hair strand for testing. The hair fibers were analyzed using a Dia-Stron Mini-Tensometer (MTT) to determine stress at break, Young's modulus, and elongation at break. Hair properties are a direct consequence of its composite structure; therefore, changes in stress at break, Young's modulus, and elongation at break represent a change in the hair structure. A conventional approach for Evaluating hair properties involves generating stress-strain curves by performing constant-rate elongation experiments, from which information about the hair structure is obtained. [Fig.l] is an example of a stress-strain curve identifying Young's modulus, plateau stress, breaking force, and elongation at break.

[0310] Breaking stress represents the force / area required to break the hair fiber. A higher breaking stress corresponds to a stronger fiber. For reference, the typical breaking stress in the dry state for healthy, unbleached hair is approximately 0.022 gmf / square micron.

[0311] Young's modulus is the slope of the initial portion of the stress-strain curve (see [Fig.l]), which is fitted in terms of cross-sectional area. It is a measure of the "elastic" properties of the hair. The Young's modulus region is sometimes referred to as the "linear" or "elastic" region of the curve.

[0312] Elongation at break is the percentage of elongation of the hair fibers at the breaking point.

[0313] Box plots were generated using Statistica™, while JMP™ analytical software was used to calculate statistics (Student's t-test at a 95% confidence level).

[0314] The results of the breaking stress (gmf / square micron) for European medium brown hair are provided in the table below and shown in [Fig.2].

[0335] The results show that multi-ethnic curly hair treated according to treatment 3 is statistically different from hair treated according to treatments 1 and 2. Hair treated according to treatment 3 has a statistically higher elongation at break. Example 3 (Cyclic fatigue test)

[0336] Inventive composition D was subjected to a cyclic fatigue test. Strands of heavily bleached European hair were used for the test (2.7 g, 27 cm). Two different hair braids were used for each treatment group. 25 fibers were taken from each of the two braids (50 fibers in total per treatment group) for testing. Each pair of braids was treated with either shampoo (control) or inventive composition D, shampoo and conditioner (inventive treatment), as described below.

[0337] Control: 0.4 g of a standard shampoo was applied to the hair strands, massaged into the hair for 30 seconds, and then left on the hair for 30 seconds. After 30 seconds, the shampoo was rinsed from the hair. The process was repeated 10 times.

[0338] Inventive treatment: 0.4 g of the inventive composition D was applied to strands of hair, massaged into the hair for 30 seconds, and then left on the hair for 5 minutes. After 5 minutes, the inventive composition D was rinsed from the hair. Then, 0.4 g of a standard shampoo was applied to the strands of hair, massaged into the hair for 30 seconds, and then left on the hair for 30 seconds. After 30 seconds, the shampoo was rinsed from the hair. After rinsing the shampoo, 0.4 g of a standard conditioner was applied to the strands of hair, and then massaged into the hair for 30 seconds. After 30 seconds, the conditioner was rinsed from the hair. The process was repeated 10 times.

[0339] After being subjected to one of the two treatments described above, the hair braids were dried for 2 minutes using a hair dryer set to medium heat. The hair fibers were periodically separated from each other with the fingers during drying. After being dried, the hair strands were stored at 60% relative humidity (60%) overnight.

[0340] After being stored overnight, hair fibers were randomly selected from each hair braid for testing. The hair fibers were subjected to a cyclic tensile fatigue test (CTF) using a Dia-Stron Mini Tensiometer (MTT). CTF is a method for determining fiber durability. CTF was conducted in constant stress mode (using the plateau stress obtained with the MTT), and a Kaplan- Meier was performed using SPSS software. Hair strands treated with the inventive treatment required more cycles to break than hair strands treated with the control treatment. This illustrates that treatment with inventive composition D improves hair durability and that multiple treatments further improve hair durability.

[0341] The results are shown in the table below and presented graphically in [Fig.8].

[0342] [Tables9] Cyclic tensile fatigue test Treatment Average cycles before failure Witness 4720 Inventive treatment 7379

[0343] The results show a statistically significant improvement in strength (more cycles required before breakage) for hair treated with inventive composition D compared to the control. Definitions

[0344] The following definitions are in addition to those presented throughout this disclosure.

[0345] As used herein, the terms "comprising," "having," and "including" (or "comprise," "have," and "include") are used in their open and non-limiting sense. The phrase "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 novel features of the claimed invention.

[0346] . Throughout the disclosure, the expression "a mixture thereof" is used, after a list of elements as shown in the following example where the letters A through F represent the elements: "one or more elements selected from the group consisting of A, B, C, D, E, F, or mixtures thereof." The phrase "a mixture thereof" does not require that the mixture include all of A, B, C, D, E, and F (although all of A, B, C, D, E, and F may be included). Rather, it indicates that a mixture of any two or more of A, B, C, D, E, and F may be included. In other words, it is equivalent to the phrase "one or more elements selected from A, B, C, D, E, F, and a mixture of any two or more of A, B, C, D, E, and F."

[0347] Similarly, the term "a salt thereof" also refers to "salts thereof." Thus, where the disclosure refers to "an element selected from the group consisting of A, B, C, D, E, F, a salt thereof, or mixtures 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.

[0348] Salts cited throughout the disclosure may include salts having a counterion such as an alkali metal, alkaline earth metal, or ammonium counterion. This list of counterions is not, however, limiting.

[0349] The expression “one or more” means “at least one” and therefore includes individual components as well as mixtures / combinations.

[0350] The term “plurality” means “more than one” or “two or more.”

[0351] Some of the various categories of components identified may overlap. In such cases where an overlap may exist and the product composition includes two (or more than two) overlapping components, an overlapping component does not represent more than one component, e.g., a component such as a fatty ester may fall within the definition of both a "fatty compound" and a "surfactant / emulsifier." If a particular composition or product requires both a fatty compound component and a surfactant / emulsifier component, a single fatty ester may only serve as the sole fatty compound or sole surfactant / emulsifier (a single fatty ester cannot serve as both a fatty compound and a surfactant / emulsifier).

[0352] All percentages, parts and ratios stated herein are based on weight, in particular, the total weight of the instant hair treatment compositions of the invention, unless otherwise indicated.

[0353] An "alkyl radical" is a saturated, linear or branched hydrocarbon-based group, in particular CrC8, more particularly C1-C6, more preferably C1-C4, such as methyl, ethyl, isopropyl and tert-butyl;

[0354] An “alkoxy radical” is an alkyloxy in which the alkyl is as described above;

[0355] An “alkenyl radical” is a group based on an unsaturated, linear or branched hydrocarbon, in particular C2-C8, more particularly C2-C6, preferably C2-C4, such as ethylenyl, propylenyl;

[0356] An “alkylene radical” is a divalent, linear or branched, C1-C8, in particular C1-C6, preferably C1-C4, saturated hydrocarbon-based group, such as methylene, ethylene or propylene.

[0357] All ranges and values ​​described herein are inclusive and combinable. For example, any value or point described herein that falls within a range described herein may serve as a minimum or maximum value to derive a sub- ranges, etc. Furthermore, all ranges provided are meant to include every specific range within given ranges, as well as any combination of subranges in between. Thus, a range of 1-5 specifically includes points 1, 2, 3, 4, and 5, as well as subranges such as 2-5, 3-5, 2-3, 2-4, 1-4, etc.; and points 1, 2, 3, 4, and 5 include ranges and subranges of 1-5, 2-5, 3-5, 2-3, 2-4, 1-4, etc.

[0358] The term "surfactants" includes salts of surfactants, even if not explicitly mentioned. In other words, whenever the disclosure refers to a surfactant, it is understood that salts of the surfactant are also included to the extent that such salts exist, even though the specification may not specifically refer to a salt (or may not refer to a salt in every instance throughout the disclosure), for example, by using language such as "a salt thereof" or "salts thereof." Sodium and potassium are common cations that form salts with surfactants. However, other cations, such as ammonium ions or alkanolammonium ions, such as monoethanolammonium or triethanolammonium ions, may also form surfactant salts.

[0359] The term "substantially free" or "essentially free" as used herein means that the specific material may be present in small amounts that do not materially affect the fundamental and novel features of the claimed invention, 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 features of the claimed invention). Similarly, the compositions may include less than 2% by weight, less than 1.5% by weight, less than 1% by weight, less than 0.5% by weight, less than 0.1% by weight, less than 0.05% by weight, or less than 0.01% by weight, or none of the specified material.The term "substantially free" or "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 starting material that is included in the composition.

[0360] Furthermore, any components that are positively presented in the present disclosure may be negatively excluded from the claims, e.g., a claimed composition may be "free," "essentially free" (or "substantially free") of one or more components that are positively presented in the present disclosure.
