Description

Title of the invention: COMPOSITIONS AND METHODS FOR TREATING HAIR Technical field

[0001] The present disclosure relates to compositions and methods for treating hair, for example for reviving curls, reshaping curls or preventing, reducing and / or repairing hair damage. CONTEXT

[0002] Consumers desire healthy and strong hair. However, various hair treatments, such as those for changing or improving the appearance of hair, for example by changing the color, style and / or shape of the hair, are known to damage the hair. In addition, repeated styling can damage the hair, for example due to the repeated use of heat and styling tools. All of these processes can break the bonds within the hair fibers, which, if not reformed, results in hair damage.

[0003] Additionally, curly hair poses more problems than straight hair. For example, curly hair tends to be more fragile and more prone to damage than straight hair. Thus, such hair treatments and processes tend to damage curly hair even more than straight hair.

[0004] For example, hair lightening and dyeing compositions and processes typically require the presence of a strong alkalizing agent, such as ammonia, as well as additional compounds, such as oxidizing agents. In order to change the color of the hair, these components must first break down the natural components of the hair fibers. Similarly, hair straightening or relaxing compositions also involve harsh chemicals to change the shape of the hair by breaking the disulfide bonds in the hair fibers.

[0005] It is known that, although such processes effectively alter the color and shape of the hair, the chemical agents used inherently cause damage to the hair and negatively impact the strength, elasticity, and porosity of the hair fibers. For example, hair that has been bleached, dyed, straightened, straightened, repeatedly styled, etc., is often dry, frizzy, and generally unpleasant to the touch and appearance. In addition, damaged hair is brittle and / or has increased elasticity, resulting in more frequent hair breakage. In naturally curly or wavy hair, this damage also tends to manifest as a loss of shape and / or curl definition. As a result, consumers are seeking formulations and processes to prevent or minimize such damage and / or repair hair that has been damaged by these treatments and processes. In addition, consumers with curly or wavy hair are seeking formulations and processes that restore and / or improve curl shape and / or definition. Consumers are also increasingly seeking formulations containing natural ingredients and free or substantially free of ingredients considered detrimental to hair, such as silicones.

[0006] However, it has proven difficult to formulate compositions that satisfactorily address these desires. For example, some compositions that attempt to address the problem of damage simply coat the hair with compounds that can improve the feel and appearance of the hair; however, this approach is only temporary and superficial. Rather than preventing or repairing hair damage, this approach simply masks the damage until the next time the hair is rinsed or washed. Other compositions attempt to treat damage within the hair fiber, but to date, they have not been satisfactory.Finally, given that consumers want to exclude certain components such as silicones, components from non-renewable sources and components that may have a negative impact on the environment, and include certain components such as those that are natural or naturally derived, finding a combination of components that effectively meets both consumer needs and desires has been difficult.

[0007] The present inventors have now discovered a synergistic combination of components that is surprisingly effective in preventing or minimizing hair damage and treating damaged hair, and restoring or reviving curls. Hair treated with the compositions according to the disclosure exhibits surprisingly reduced signs of damage, including increased strength and / or reduced elasticity, and more visible curl shape and definition.

[0137] In other preferred embodiments, the fatty compound comprises, consists essentially of, or consists of ucuuba butter, lauric acid, cetearyl alcohol, cetyl esters, or combinations of two or more thereof. In particularly preferred embodiments, the fatty compound includes ucuuba butter, which is present in an amount of about 0.1%, about 0.2%, about 0.3%, about 0.4%, about 0.5%, about 0.6%, about 0.7%, about 0.8%, about 0.9%, about 1%, about 1.1%, about 1.2%, about 1.3%, about 1.4%, about 1.5%, about 1.6%, about 1.7%, about 1.8%, about 1.9%, or about 2% by weight, including all ranges and sub-ranges using any of the foregoing values ​​as upper and lower limits, based on the total weight of the composition.

[0138] It may be particularly advantageous, in terms of providing benefits to the hair, to select amounts of esters and fatty compounds relative to one another. Therefore, in some embodiments, the total amount of fatty compounds in the composition is greater than the total amount of esters. For example, in some embodiments, the composition may have a weight ratio of total fatty compounds to total esters ranging from about 2 to about 8, such as from about 2.5 to about 7.5, from about 3 to about 7, from about 3.5 to about 6.5, from about 4 to about 6, from about 4.25 to about 5.5, from about 4.25 to about 5, or from about 4.4 to about 4.8.

As a preferred but non-limiting example, the composition may comprise ucuuba butter and pentaerythrityl tetraisostearate, wherein the weight ratio of ucuuba butter:pentaerythrityl tetraisostearate is from about 0.1 to about 1, such as from about 0.15 to about 0.9, from about 0.2 to about 0.8, from about 0.25 to about 0.7, from about 0.3 to about 0.6, or from about 0.3 to about 0.5, or is about 0.15, about 0.2, about 0.25, about 0.3, about 0.35, about 0.4, about 0.45, or about 0.5, including all ranges and sub-ranges using any of the foregoing values ​​as upper and lower limits. Thickening agents

[0140] The compositions according to the disclosure optionally comprise at least one thickening agent. Useful thickening agents include, but are not limited to, semi-synthetic polymers, such as semi-synthetic cellulose derivatives, synthetic polymers, such as carbomers, poloxamers, and acrylate / beheneth-25 methacrylate copolymers, acrylate copolymers, polyethyleneimines (e.g., PEL10), natural polymers, such as acacia, tragacanth, alginates (e.g., sodium alginate), carrageenan, vegetable gums, such as xanthan gum, guar gum, petroleum jelly, waxes, related particulate colloids, such as bentonite, colloidal silicon dioxide, and microcrystalline cellulose, celluloses such as hydroethylcellulose and hydroxypropylcellulose, and guars such as hydroxypropyl guar.If present, the composition preferably comprises thickening compound(s) which is / are natural or of natural origin.

A non-limiting example of an amphoteric associative polymer is acrylates / beheneth-25 methacrylate copolymer, and non-limiting examples of anionic associative polymers include acrylates copolymer and acrylates-4 crosslinked polymer.

[0142] If present, the total amount of thickening agents may range from about 0.01% to about 8%, such as from about 0.05% to about 5%, from about 0.1% to about 4%, from about 0.2% to about 3%, or from about 0.3% to about 2% by weight, based on the total weight of the composition. Auxiliary components

[0143] The compositions according to the disclosure may optionally include one or more auxiliary components. Non-limiting examples include preservatives, perfumes, pH adjusters, salts, antioxidants, vitamins, vitamin derivatives, ceramides, botanical extracts, proteins, protein hydrolysates, protein isolates, hydrotropes, pearlescent agents, buffers, sequestering agents, and the like.

[0144] The total amount of auxiliary components, if present, typically ranges from about 0.01% to about 10%, based on the total weight of the composition. For example, in some embodiments, the individual amounts of each component or the total amount of components may range from about 0.1% to about 10%, from about 0.1% to about 8%, from about 0.1% to about 5%, from about 0.1% to about 4%, from about 0.1% to about 3%, from about 0.1% to about 2%, from about 1% to about 10%, from about 1% to about 8%, from about 1% to about 5%, from about 1% to about 4%, from about 1% to about 3%, or from about 1% to about 2% by weight, based on the total weight of the composition.

[0145] The compositions according to the disclosure typically have a pH of less than or equal to about 7, such as less than or equal to about 6, less than or equal to about 5, less than or equal to about 4.5, or less than or equal to about 4. For example, the compositions may have a pH ranging from about 1 to about 7, such as from about 2 to about 6, from about 2.5 to about 5.5, from about 2.5 to about 5, from about 2.5 to about 4.5, or from about 3 to about 4. In some embodiments, the pH of the composition may be, for example, about 3, about 3.25, about 3.5, about 3.75, or about 4, including all ranges and subranges therein.

[0146] The compositions may be in any suitable form. For example, the compositions may be a liquid, a gel, a cream-gel, a high, medium or low density cream, a serum, a lotion, etc. In preferred embodiments, the compositions are hair masks or deep conditioning treatments that are in the form of a lotion or cream. II. METHODS

[0147] The disclosure further relates to methods of treating hair, particularly curly or wavy hair. The methods of treating hair may be methods of restoring or improving the shape and / or definition of curls. Surprisingly, the shape and / or definition of curls obtained with the compositions according to the disclosure may be long-lasting. For example, the shape and / or definition of curls may persist through one or more hair wash cycles, for example two or more, or even three or more.

[0148] Methods of treating hair may be methods of reducing or preventing damage to hair, protecting hair from damage, restoring the moisture balance of hair fibers, providing strength to hair fibers, improving the elasticity of hair fibers and / or maintaining the moisture balance, strength and / or elasticity of hair fibers. In some embodiments, the hair treatment methods prevent hair damage from becoming so severe that it cannot be repaired, i.e., prevent irreversible hair damage.

[0149] The methods include applying a composition according to the disclosure (a "curl revitalizing composition") to the hair, optionally leaving the composition on the hair for a period of time ("processing time", "resting period" or "setting period"), and optionally rinsing the composition from the hair. The methods may optionally include repeating the treatment at least once, such as at least twice, at least three times, at least four times, at least five times, etc., or as needed to revive or restore curl definition and / or treat the hair.

[0150] The application period may be for a time deemed appropriate to allow the active agents to provide benefits to the hair, such as about 30 seconds, about 1 minute, about 2 minutes, about 5 minutes, about 10 minutes, about 15 minutes, about 20 minutes, about 30 minutes, about 45 minutes, about 1 hour, about 2 hours, about 4 hours, about 6 hours, about 8 hours, about 10 hours, about 12 hours, about 16 hours, about 20 hours, about 24 hours, etc., or may vary by a period of time using any of the foregoing values ​​as upper and lower limits.By way of non-limiting example, the application period may range from approximately 2 minutes to approximately 4 hours, from approximately 5 minutes to approximately 2 hours, from approximately 10 minutes to approximately 1.5 hours, from approximately 20 minutes to approximately 1 hour, from approximately 1 hour to approximately 12 hours, from approximately 2 hours to approximately 10 hours, from approximately 4 hours to approximately 8 hours, from approximately 8 hours to approximately 24 hours, from approximately 8 hours to approximately 12 hours, etc. For example, an application time may be overnight or until the next rinsing or shampooing of the hair according to the user's usual hygiene rules.

[0151] Although not necessary, methods of using the compositions of the disclosure may also include a step of heating the hair to which the composition has been applied, for example during the resting period while the composition is on the hair. For example, a hair dryer, a hair dryer hood, etc., may be used.

[0152] At least in some embodiments, the hair that may be treated according to the methods described herein may be hair that has been previously bleached, dyed, straightened, relaxed, etc. It will be understood that the hair that is treated according to various methods described herein may be hair that has been previously subjected to such chemical treatments and therefore need to be repaired, have curls reshaped, have curls revived or the like. Thus, the processes may occur within any period of time after such a chemical treatment following which the benefits of repair, curl reshaping, curl revitalization, etc. are desired. For example, the processes may occur within six months of a chemical treatment, such as bleaching, dyeing, straightening, relaxing, etc., such as within five months, within four months, within three months, within two months, within one month, within three weeks, within two weeks, within one week, within five days, within four days, within three days, within two days, within one day, within 12 hours, within 8 hours, within 6 hours, within 4 hours, within 2 hours, or within one hour of such treatment.The period during which it is contemplated to implement the methods according to the disclosure is not limited.

[0153] In an exemplary embodiment, a composition according to the disclosure may be applied to hair, for example, to reshape or revive curls or waves, to improve the overall health and appearance of curls or waves, to improve the elasticity of hair fibers, to prevent or reduce damage to hair fibers, etc., by applying a composition to wet, damp, or dry hair, leaving the composition on the hair for an appropriate processing time, optionally rinsing the hair, and then, optionally, drying and / or styling the hair according to the individual's routine.

[0154] In other exemplary embodiments, a composition according to the disclosure may be applied to the hair before, during, and / or after a chemical hair treatment process. For example, such a routine may include applying a composition according to the disclosure to wet, damp, or dry hair, leaving the composition on the hair for an appropriate treatment time, optionally rinsing the hair, and then substantially immediately thereafter (i.e., as part of the same chemical hair treatment process), preferably with intervening rinsing of the hair, applying a chemical treatment such as a bleaching, dyeing, straightening, relaxing, or perming composition to the hair.Another such routine may include applying a chemical treatment, such as a bleaching, dyeing, straightening, relaxing, or perming composition, to the hair, and substantially immediately thereafter (i.e., as part of the same chemical hair treatment process), preferably with an intervening rinsing of the hair, applying to the hair a composition according to the disclosure. Thus, it is contemplated that the compositions according to the disclosure may be incorporated into a chemical hair treatment process, thereby reducing, minimizing, or . prevent damage to hair that might otherwise result from such harsh chemical treatments. By incorporating such compositions into chemical treatment processes, the shape or definition of curls or waves can be maintained.

[0155] Surprisingly, hair treated with compositions and methods according to the disclosure exhibits less damage than hair not treated with compositions and methods according to the disclosure and, as a result, greater curl retention or recovery. The reduction in damage is particularly notable on hair damaged due to harsh chemical treatments, such as bleaching, dyeing, perming, straightening, relaxing, etc., as well as due to repeated styling, for example with heat or styling tools. Hair repaired using compositions and methods according to the disclosure may have lower elasticity and / or higher tensile strength than similarly damaged hair not treated according to the disclosure, as well as more defined curls and waves.

[0156] The expression "and / or" should be understood to include both the conjunctive and the disjunctive. For example, "amino acids and / or salts thereof" means "amino acids and salts thereof" as well as "amino acids or salts thereof", and expressly covers cases of either.

[0157] As used herein, the term "salts" throughout the disclosure may include salts having a counterion such as an alkali metal, alkaline earth metal, or ammonium counterion. This list of counterions, however, is not limiting. Salts also include a dissociated form of a compound, for example, in an aqueous solution.

[0158] The terms and phrases "curls," "curly hair," "waves," or the like, which are used interchangeably herein, refer to any hair including a curl or wave. The degree of curl of the hair may vary and is not limited. The curl may be natural or unnatural, i.e., formed by chemical or physical treatment of the hair, although it is preferred that the curl be natural.

[0159] As used herein, the term "applying a composition to the hair," and variations thereof, is intended to mean contacting the hair with at least one of the compositions of the disclosure in any manner. It may also mean contacting the hair in an effective amount.

[0160] The term "treating the hair" (and its grammatical variations) as used herein refers to applying the compositions of the present disclosure to the surface of the hair. The term "treating the hair" (and its grammatical variations) as used herein also refers to contacting the hair with the compositions of the present disclosure.

[0161] As used herein, the phrases "revive curls," "enhance curl recovery," "reshape curls," "reshape curly hair," or the like, are intended to mean that the intensity and / or shape of the curl or wave of the hair, which may have been reduced as a result of damage, is increased by treatment with compositions or methods described herein. An increase in curl or wave can be any increase, for example, an increase in curl shape and / or an increase in curl definition. It will be understood, however, that an increase in curl provided by the compositions and methods according to the disclosure is due to the compositions and methods restoring curl or wave to the hair, rather than providing curl or wave to naturally straight, unpermed hair.As is known, an increase in curl or wave may be observed visually, for example when treated hair appears curlier than pre-treated hair, or when the curls or waves appear more defined; it may be determined by measuring the length of a strand of hair, with a shorter strand of hair being considered curlier than a longer strand; or it may be determined by any other accepted method.

[0162] As used herein, the terms "curl revitalizing composition," "curl restoring composition," or the like refer to a composition according to the disclosure. These compositions may restore or revive curls to any degree, without limitation. However, in at least some embodiments, the degree of curl revitalization may be at least about 10%, at least about 12%, at least about 15%, at least about 18%, at least about 20%, at least about 22%, or at least about 25% relative to the hair before treatment.

[0163] As used herein, the term "natural" and the expression "naturally occurring" refer to a material of natural origin, for example of plant origin, which may or may not be subsequently chemically or physically modified.

[0164] As used herein, the term "component having a negative environmental impact" and its variations means any component that may itself have a negative environmental impact, or any component whose harvesting, processing, etc., may have a negative environmental impact.

[0165] For the purposes of this disclosure, the terms "vegetable oil" and "vegetable oil / vegetable butter" are intended to include both oils and butters (e.g., ucuuba oil and ucuuba butter), unless expressly stated otherwise. EXAMPLES

[0166] The following examples are intended to be non-limiting and explanatory in nature only. In the Examples, unless otherwise indicated, the amounts are expressed as a percentage by weight (% by weight) of active ingredients, relative to the total weight of the composition. Example 1 - Compositions

[0167] Compositions IA and IB according to the disclosure were prepared as shown in Table 1.

[0168] [Table 1]

[0169] [Tables 1] IA IB Basic amino acid(s) 3.8 3.8 Thickening agent(s) 0.9 0.9 Nonionic surfactant(s) 0.5 0.5 Cationic surfactant(s) 3.0 3.0 Glycine betaine 1.8 1.8 Citric acid 5.5 5.5 Wax(s) 0.5 0.5 Fatty alcohol(s) 6.3 6.3 Vegetable oil(s) 0.5 Ester(s) 2.5 1.5 Additives (preservatives, perfume, vitamins) <2 <2 Solvents (water and non-aqueous solvents) Qs per 100 Qs per 100

[0170] Compositions IA and IB, which include a combination of amino acids (arginine), osmolytes (trimethylglycine), carboxylic acids (citric acid), esters (pentaerythrityl tetraisostearate), surfactants and fatty compounds are hair mask compositions free of silicone compounds and include more than 70% components from renewable sources. Composition IB includes a vegetable oil (ucuuba butter) in addition to waxes and fatty alcohols.

[0171] Example 2- Evaluation of curl recovery and cosmetic benefits

[0172] The following studies were conducted to evaluate the effectiveness of the compositions according to the disclosure for reviving or recovering curls, providing curl definition and providing cosmetic benefits to treated hair. Example 2A#- Leave-in treatment

[0173] Equal amounts of composition IA or IB were applied to three strands of Caucasian curly hair. The compositions were left on the hair and the strands were air-dried at room temperature.

[0174] [Fig. 2C] shows the strands before treatment, and Figures 2A and 2B show the strands after treatment with compositions IA and IB, respectively. As Figures 2A to 2C demonstrate, the degree of curl and curl definition restored to the hair with the treatment according to the disclosure is significant. In addition, the strands exhibit a significant reduction in frizz and volume, and increased shine and smooth texture. Example 2B#- Treatment with rinsing

[0175] Equal amounts of composition IB were applied to six strands of previously bleached curly Caucasian hair. The compositions were rinsed from the hair and the strands were allowed to air dry at room temperature.

[0176] [Fig. 3A] shows images of three strands bleached using a standard bleaching protocol at room temperature (27°C) before and after treatment with Composition IB, and [Fig. 3B] shows images of three strands bleached using an accelerated bleaching protocol at increased temperature (37°C) before and after treatment with Composition IB. As Figures 3A and 3B demonstrate, the bleached hair before treatment had lost curl definition, but the degree of curl and curl definition restored to the hair after treatment is significant. In addition, the strands exhibit a notable reduction in frizz and volume, and increased shine and smooth texture after treatment.

[0177] Example 2 demonstrates that the compositions according to the disclosure surprisingly and unexpectedly restore curl and curl definition to damaged hair and provide cosmetic benefits to treated hair.
