Description

Title of the invention: METHODS FOR TREATING KERATIN FIBERS Technical field

[0001] The present disclosure relates to methods of treating keratin fibers, such as hair, for example repairing damaged keratin fibers, providing strength to the keratin fibers and / or reducing the elasticity of the keratin fibers, in connection with a keratin fiber shaping process. BACKGROUND

[0002] Consumers use cosmetic compositions and processes to change or enhance the appearance of their hair, for example, by changing the color, style, and / or shape of the hair, and / or by imparting various properties to the hair, such as shine and conditioning. However, many compositions and processes for changing the appearance of hair, such as compositions and methods for permanently changing the color or shape of hair, involve harsh chemical treatments. 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, result in damage to the hair.

[0003] It is known that, although such processes effectively alter the color or 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, chemically straightened or relaxed, permed, etc., is often dry, frizzy, and appears unhealthy to the touch and appearance. In addition, damaged hair is brittle and / or has increased elasticity, resulting in more frequent hair breakage. As such, consumers are seeking compositions and processes to prevent or minimize such damage and / or repair hair that has been damaged by these treatments and processes.In particular, consumers want hair that is strong, does not break easily, can be stretched or manipulated while retaining the ability to return to its original state without breaking (i.e., reduced elasticity), feels soft and healthy, and also looks shiny and healthy.

[0004] However, it has proven difficult to formulate compositions that satisfactorily meet these wishes. For example, some compositions that attempt to provide a solution only 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.

[0005] 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. Hair treated with compositions according to the disclosure exhibits surprisingly reduced signs of damage, including increased strength and / or reduced elasticity, particularly hair that has been damaged by harsh chemical treatments such as those involved in permanent hair styling processes.

[0110] These compositions comprise at least one hair-shaping agent, which may, for example, be a reducing agent and / or an alkaline agent. In at least some cases, hair-shaping compositions alter the shape of the hair by opening the disulfide bonds of keratin fibers, often with a sulfur-based reducing agent. After opening the disulfide bond and reshaping the hair by mechanical means, for example, using rods or rollers, the bonds are reconstituted by means of an oxidizing or "fixing" agent. The hair shape obtained by such processes is generally considered permanent in that it persists even after one or more styling and shampooing processes. However, at least some hair-shaping compositions and processes do not include a step of applying an oxidizing or fixing composition.

[0111] In various embodiments, the hair styling compositions used in the methods described herein comprise at least one reducing agent, which may be a thiol-based reducing agent. The term "thiol-based" refers to a compound having one or more thiol groups (-SH), wherein said thiol group(s) is optionally in the form of an organic or inorganic salt. For example, the thiol-based reducing agents present in the styling composition may be chosen from organic compounds comprising one or more mercapto groups (-SH or -S-), or disulfide groups (-SS-), preferably -SH groups, and may include at least one other function chosen from carboxylic acid, amine, amide, ester and alcohol functions.

[0129] Examples of compounds of formula (V) include 1,3-diaminopropane, 1,3-diamino-2-propanol, spermine and / or spermidine.

[0130] Alkanolamines are organic amines comprising a primary, secondary or tertiary amine function, and one or more linear or branched C1-C8 alkyl groups carrying one or more hydroxyl radicals. For example, hair styling compositions may include monoalkanolamines, dialkanolamines or trialkanolamines comprising one to three hydroxyalkyl radicals. in C1-C4, identical or different, such as monoethanolamine, diethanolamine, triethanolamine, monoisopropanolamine, diisopropanolamine, N,N-dimethylethanolamine, 2-amino-2-methyl-l-propanol, triisopropanolamine, 2-amino-2-methyl-l,3-propanediol, 3-amino-l,2-propanediol, 3-dimethylamino-l,2-propanediol and / or tris(hydroxymethyl)aminomethane.

[0131] In some cases, ammonium carbamate is used, alone or in combination with other alkaline agents such as ammonia and / or ammonium (bi)carbonate.

[0132] The hair shaping compositions are typically basic, having a pH greater than 7, for example, greater than about 7.5, greater than about 8, greater than about 8.5, greater than about 9, greater than about 10, greater than about 11, or greater than about 12. In some cases, the hair shaping composition has a pH ranging from about 7.5 to about 11, from about 7.5 to about 10, from about 7.5 to about 9.5, from about 7.75 to about 9.25, from about 8 to about 9.25, or from about 8 to about 9.

[0133] Hair styling compositions typically also include additional components such as solvents, thickening agents, emulsifying agents, pH adjusters, conditioning agents, preservatives, fragrances, etc.

[0134] At least some hair shaping processes include a step of applying an oxidizing or fixing composition (also referred to as a "neutralizing" composition) to the hair after the shaping composition has been left on the hair for a processing period, for example, from about 15 minutes to about 1 hour, or from about 20 minutes to about 45 minutes.

[0135] The fixing composition may comprise hydrogen peroxide as an oxidizing agent. Typically, the hydrogen peroxide is present in an amount of less than about 15%, such as less than about 10%, less than about 8%, less than about 6%, less than about 4%, for example, from about 0.5% to about 5%, from about 0.5% to about 3%, or from about 0.5% to about 2% by weight, based on the total weight of the fixing composition.

[0136] In some cases, the fixing composition comprises crosslinking agents capable of crosslinking the bonds in the keratin fiber. These crosslinking agents may be chosen from diols, carboxylic acids, amines, diamines, reducing sugars, carbonyls or carboxylic acids, for example 1,7-diaminoheptane, 1,4-diaminobutane, 6-aminohexan-1-ol, 6-aminohexanoic acid, 2-aminoacetic acid, 2-amino-2-oxo-ethanoic acid, 4-aminobutanoic acid, ribose, arabinose, xylose, lyxose, galactose, mannose, 3-(2-hydroxyethyl)-2-oxa zolidinone, hexane-2,5-dione, butane-2,3-dione, ethanedial, 2-hydroxy-butanedial, 4-oxo-pentanoic acid, 1,4-butanediol, 1,6-hexanediol, 1,2,4-butanetriol, 1,2,6-hexanetriol, butanedioic acid, heptanedioic acid, oxoethanoic acid, 2,2-dihydroxyethanoic acid, 2,2'-oxybis(2-hydroxy)-ethanoic acid, 2-hydroxypropane-1,2,3-tricarboxylic acid, 1,2,3,4-butanetetracarboxylic acid, l,3-dioxolan-2-one, dimethyl carbonate, diethyl carbonate, diphenyl carbonate, l,3-dioxan-2-one or 4-methyl-l,3-dioxolan-2-one.

[0137] Other hair-styling compositions work by locking the keratin in place rather than breaking the keratin bonds. Brazilian straightening treatments, for example, use formalin optionally in combination with one or more silicone polymers.

[0138] Although not required, a step of heating hair to which a hair-shaping composition has been applied is often used in hair-shaping processes that may be used in methods according to the disclosure.

[0139] Although the aforementioned hair shaping compositions may be used in the methods according to the disclosure, those skilled in the art will appreciate that variations of hair shaping compositions and processes may also be used. Thus, the foregoing is not intended to limit the methods according to the disclosure.

[0140] III. METHODS FOR TREATING KERATIN FIBERS

[0141] The disclosure relates to methods of treating keratin fibers with a treatment composition according to the disclosure in connection with a permanent hair styling process. The methods include applying a treatment composition to the hair, optionally leaving the composition on the hair for a period of time ("treatment time", "rest period" or "lay-in period"), and optionally rinsing the composition from the hair. The treatment composition may be applied to the hair before and / or after applying a hair styling composition to the hair, or may be applied to the hair simultaneously with a hair styling composition.

[0142] Although not required, the methods according to the disclosure may also include a step of heating the hair to which the treatment composition has been applied, for example during the rest period while the treatment composition is on the hair. For example, a hair dryer, a hair dryer hood, etc., may be used.

[0143] The period of time the treatment composition is left on the hair may be for a suitable time to allow the active agents to provide benefits to keratin fibers, 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, etc., or may vary by a period of time using any of the preceding values ​​as upper and lower limits.By way of non-limiting example, the exposure period may range from about 30 seconds to about 60 minutes, from about 30 seconds to about 45 minutes, from about 30 seconds to about 30 minutes, from about 30 seconds to about 20 minutes, from about 30 seconds to about 15 minutes, from about 30 seconds to about 10 minutes, from about 30 seconds to about 5 minutes, 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 2 minutes to about 60 minutes, from about 2 minutes to about 45 minutes, from about 2 minutes to about 30 minutes, from about 2 minutes to about 20 minutes, from about 2 minutes to about 15 minutes, from about 2 minutes to about 10 minutes, from about 2 minutes to about 5 minutes, etc.

[0144] The period of time the hair shaping composition is left on the hair may be a suitable time to achieve the desired shaping effect, which may range from about 1 minute to about 60 minutes, such as from about 3 minutes to about 45 minutes, from about 5 minutes to about 35 minutes, or from about 10 minutes to about 30 minutes.

[0145] Optionally, the hair may be heated, for example with a hair dryer, hair dryer hood, etc., while the styling composition is on the hair.

[0146] In at least some embodiments, an oxidizing or fixing composition is applied to the hair after application of the hair-shaping composition to the hair, for example after a desired setting or processing time.

[0147] In exemplary embodiments, a treatment composition according to the disclosure may be applied to the hair before, during, and / or after applying a hair-shaping composition to the hair, with or without an intermediate rinse. For example, such a method may include applying a treatment composition according to the disclosure to wet, damp, or dry hair, leaving the composition on the hair for an appropriate processing time, optionally rinsing the hair, and then substantially immediately thereafter (i.e., within the same hair-shaping process), with or without an intermediate rinse of the hair, applying a hair-shaping composition. hair to hair. Another exemplary method may include applying a styling composition to the hair, and substantially immediately thereafter (i.e., within the same hair styling process), with or without an intervening rinsing of the hair, applying a treatment composition according to the disclosure to the hair. In either of the preceding exemplary embodiments, the treatment composition and the hair styling composition may optionally be layered one upon the other on the hair (leave-in), or may optionally be applied to the hair in alternating layers (rinsing) during the hair styling process. As another exemplary method, a treatment composition according to the disclosure may be added to or mixed with a hair styling composition, for example, at or near the time of use.In yet another exemplary method, a treatment composition and a styling composition may be applied simultaneously to the hair, for example, by means of a dual-chamber applicator that is configured to dispense two compositions at the same time. Thus, it is contemplated that the treatment compositions of the disclosure may be incorporated into a hair styling process, thereby reducing, minimizing, or preventing damage to the hair that might otherwise result from such harsh chemical treatments.

[0148] As a non-limiting example of methods according to the disclosure, a treatment composition as described herein may be applied to wet, damp, or dry hair and then allowed to remain for a development time as described herein, for example, from about one minute to about two hours, such as from about five minutes to about one hour, optionally with heating. The hair may then be rinsed, and then a hair-styling composition is applied thereto according to conventional hair-styling routines. As another non-limiting example of methods according to the disclosure, a treatment composition as described herein may be applied to wet, damp, or dry hair and then allowed to remain for a development time as described herein, for example, from about one minute to about two hours, such as from about five minutes to about one hour, optionally with heating.Without rinsing the hair treatment composition, a hair shaping composition can be applied to the hair, and then the hair shaping process is applied according to conventional hair shaping routines.

[0149] As another non-limiting example of methods according to the disclosure, a hair-styling composition may be applied to the hair. The hair may then be rinsed and then a treatment composition as described herein is applied thereto, which may be left on for a treatment time. as described herein, for example, from about one minute to about two hours, such as from about five minutes to about one hour, optionally with heating. The hair may then be rinsed. As another non-limiting example of methods according to the disclosure, a hair-styling composition may be applied to the hair according to conventional hair-styling routines, and without rinsing the hair-styling composition, a treatment composition as described herein may be applied and then allowed to set for a development time as described herein, for example, from about one minute to about two hours, such as from about five minutes to about one hour, optionally with heating. The hair may then be rinsed.

[0150] Surprisingly, hair that has been treated with treatment compositions and methods according to the disclosure before, during and / or after the hair shaping process exhibits less damage than hair subjected to such hair shaping processes but not treated with treatment compositions and methods according to the disclosure before, during and / or after the process. The hair may have lower elasticity and / or higher tensile strength than similarly permanently reshaped hair but not treated according to the disclosure.Thus, additional methods according to the disclosure include methods of reducing or minimizing damage to hair in a hair reshaping process, methods of preventing damage to hair from a hair reshaping process, and methods of improving elasticity and / or tensile strength of hair in a hair reshaping process.

[0151] 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. Further, it should be appreciated 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 herein are provided for the present disclosure only.

[0152] As used herein, treating hair with a treatment composition or applying a treatment composition to hair that is "in connection with a hair shaping process," "within the same hair shaping process," and variations thereof, are intended to convey that the treatment composition is applied to the hair in close proximity to when the hair is subjected to a hair shaping process, such that one skilled in the art would consider hair treatment processes with a treatment composition as described herein and hair shaping as a single process. For example, the treatment composition may be applied to the hair less than 24 hours, such as less than 12 hours, less than 6 hours, less than 4 hours, less than 3 hours, less than 2 hours, less than 1 hour, less than 45 minutes, less than 30 minutes, or less than 15 minutes before and / or after applying a hair shaping composition to the hair.

[0153] The expression "and / or" should be understood to include both the conjunctive and the disjunctive. For example, "amino acids and / or their salts" means "amino acids and their salts" as well as "amino acids or their salts", and expressly covers cases of either.

[0154] 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.

[0155] As used herein, if a component is described as being present "in an amount less than or equal to" a certain amount, it is intended that such component is in fact present in the composition, i.e., is present in an amount greater than 0%.

[0156] All quantities stated herein are relative to the amount of active ingredient unless otherwise stated.

[0157] All percentages, parts and ratios herein are based on the total weight of the compositions of the present disclosure, unless otherwise indicated.

[0158] In the present application, the expression "keratin fibers" and the term "hair" are used interchangeably, without this being limiting. The person skilled in the art will understand that keratin fibers include hair, such as hair growing on the scalp.

[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 described herein, 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 described herein 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 described herein.

[0161] The terms "hair shaping," "hair reshaping," and the like, which may be used interchangeably herein, refer to processes that involve chemical reshaping of the hair that is considered by the person skilled in the art as being permanent. “Permanent” hair shaping means that the shape of the hair fiber achieved by the process lasts through several styling and washing routines, for example at least 2, at least 5, or at least 10 washing routines. However, the expressions “hair shaping” and “hair reshaping” are not intended to refer to processes that the person skilled in the art considers temporary, such as straightening hair with a hair straightener in the absence of reducing or alkaline agents, curling hair with a curling iron in the absence of alkaline reducing agents, or the like.
