Description

Title of the invention: COMPOSITIONS AND METHODS FOR MODIFYING HAIR COLOR technical field

[0001] The disclosure relates to compositions and processes for modifying the color, tone, and / or shade of hair. The compositions and processes can be used to modify hair color by removing various colors, tones, and / or shades from the hair. CONTEXT

[0002] Consumers often wish to change their hair color. For example, as a person ages, the hair follicle loses its natural pigment, resulting in gray, silver, or white hair. It is common for consumers to dye their gray hair, for example, to match their natural hair color. Similarly, consumers may wish to change the color, tone, and / or shade of their hair from their natural color or a previous hair dye job; for example, they may wish to change to a completely different color, lighten or darken their hair color, make their hair color warmer or cooler, etc. The most common hair dyeing processes are permanent, semi-permanent, and temporary hair dye.

[0003] Semi-permanent or temporary hair dye compositions typically use pigments, oil-soluble dyes, or direct dyes that are deposited onto the hair fiber to impart color to the hair. Generally, these hair dyes are removed by washing the hair after one or more shampoo cycles.

[0004] Furthermore, permanent hair dye compositions use oxidation dye precursors, which are also known as primary intermediates or couplers. In order to offer various colors, tones, and shades of permanent hair color, dye compositions contain various combinations of different types of oxidation dye compounds. These oxidation dye compounds are small, colorless or faintly colored compounds that, when combined with oxidizing agents, form colored complexes through an oxidative condensation process. Permanent hair dye compositions also contain ammonia or other alkalizing agents that cause the hair shaft to swell, thus allowing the oxidative dye molecules to penetrate the cuticle and the cortex before the oxidation condensation process is complete. The larger color complexes resulting from the oxidative reaction are then trapped inside the hair fiber and cannot be removed by washing, thus permanently altering the hair color.

[0005] Since permanent hair dyes cannot be removed by washing the hair, if an individual who has previously changed the color or tone of their hair with a first oxidative dye composition wishes to change the color or tone of their previously colored hair, some or all of the color imparted by the first oxidative dye composition must be neutralized. For example, a consumer may wish to remove the first color or tone in order to return to their natural hair color, or to obtain a second color different from the first color by using a second oxidative dye composition. In such cases, it is necessary to remove all of the first hair color, either to allow the natural hair color to be visible or to prevent the first color from interfering with the appearance of the second color.As another example, a consumer may wish to achieve a second tone or shade within the same color family as the first color, such as changing hair color from dark brown to light brown, and may therefore wish to remove some, but not necessarily all, of the first color. Alternatively, the desired change may be more subtle, for example, making the first color warmer or more vibrant. Thus, depending on the specific combination of oxidation dye compounds present in the first dye composition, and the desired second color or tone, different levels and types of color removal are required.

[0006] Although there are known processes that are effective in removing the first hair color, these processes have drawbacks. For example, a common color removal process uses oxidizing agents, but these compositions are aggressive and cause damage to the hair, making it fragile, brittle, and giving it an unhealthy appearance. This can be particularly problematic since the hair has already been subjected to harsh chemicals such as alkalizing and oxidizing agents in the first oxidative dye composition, and the integrity of the hair fibers is therefore already compromised. Moreover, these compositions can essentially remove all of the hair color, and consequently, the subsequent application of a second oxidative dye composition is necessary to achieve the desired second color or tone.This step, known as . "Touching up" the color exposes the hair more to harsh chemicals and leads to further damage.

[0007] Given the damage associated with the use of oxidizing agents as color removers, a second option is to neutralize the first molecules of oxidative dye with color-removing agents such as thiol-based compounds. However, these compositions have not been as effective at removing color as those using oxidizing agents. For example, some oxidative dye compounds, particularly those that impart darker colors such as blacks, ash browns, chestnuts, ash mochas, natural ash (blue or green), ash violets, violets, red violets, reds, red mochas, red browns, mahogany, red coppers, coppers, and golds, are more resistant to removal using thiol-based color removers than to removal using oxidizing agents.As such, the color result obtained with these color-removing agents may not be satisfactory when used on hair that has been dyed with such compounds, and the remaining color will interfere with the colorist's attempt to achieve the desired color, tone, or shade.

[0008] Although attempts have been made to solve these problems, for example by adding components to the composition containing the oxidizing agent to minimize damage to the hair or by using different color-removing agents, there has not yet been an effective composition or process for removing oxidative color to allow a change in hair color that adequately minimizes or eliminates damage to the hair.Thus, the choices available today for consumers who wish to change the color of their previously dyed hair are either (1) to remove all of the hair color with a color removal composition containing harmful oxidizing agents, and then expose the hair to further damage with a second oxidative dye composition to achieve the desired color or tone, or (2) to remove only the hair dyes of the first color that are likely to be removed with other color removal agents such as thiol-based compounds, and attempt to achieve the desired color or tone with a second oxidative dye composition despite the first color remaining.

[0009] It has now been discovered, surprisingly, that compositions comprising organic acids allow the controlled removal of artificial color from previously dyed hair, providing desired modifications to the color, tone, and / or shade of the hair. These compositions are unique in that they can thus be used in color removal processes. to achieve a desired color, tone, and / or shade, just as consumers experience when undergoing a hair dyeing process, even without a touch-up step. Furthermore, the formulas are free or virtually free of oxidizing agents, thus minimizing or eliminating the hair damage typically associated with hair color removal formulas and processes. SUMMARY

[0010] The disclosure relates to compositions and processes that can be used to remove artificial hair color, particularly from hair that has been previously dyed with an oxidative dye composition. In various embodiments, the compositions and processes can remove some or all of certain dyes, while having minimal or no impact on other dyes. As such, the color left on the hair can be "adjusted" to achieve the result desired by the consumer.

Hair color removal agents

[0075] The compositions according to the disclosure may optionally include at least one compound traditionally used as a hair color-removing agent, such as thiol-based compounds. Salts of hair color-removing agents may also be selected. Non-limiting examples of salts include sodium salts, ammonium salts, lithium salts, potassium salts, and calcium salts.

Preferably, where appropriate, the hair color-removing agents are not oxidizing agents. For example, where appropriate, the hair color-removing agents may include, consist essentially of, or consist of reducing agents. In other embodiments, the compositions are free or substantially free of any of the aforementioned hair color-removing agents. For example, in some embodiments, the compositions are free or substantially free of hair color-removing agents other than thiol-based compounds, such as thiosalicylic acid, thiolactic acid, and / or their salts.

[0077] Where appropriate, the total quantity of such hair color-removing agents may range from approximately 0.5% to approximately 20%, such as from approximately 1% to approximately 18%, from approximately 2% to approximately 15%, or from approximately 4% to approximately 12% by weight, relative to the total weight of the composition. For example, the total quantity of such hair color-removing agents may be approximately 1%, approximately 2%, approximately 3%, approximately 4%, approximately 5%, approximately 6%, approximately 7%, approximately 8%, approximately 9%, approximately 10%, approximately 11%, approximately 12%, approximately 13%, approximately 14%, or approximately 15% by weight, relative to the total weight of the composition, including any range using any of the preceding values ​​as upper and lower limits. Auxiliary components

[0078] 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 (e.g., tocopherol), vitamin derivatives, botanical extracts, buffers, sequestering agents, and the like. In some embodiments, the compositions are free or substantially free of any of the aforementioned elements.

[0079] The total quantity of auxiliary components, if any, typically ranges from about 0.01% to about 15% by weight, relative to the total weight of the composition. For example, in some embodiments, the individual quantities of each component or the total quantity of components may range from approximately 0.1% to approximately 10%, from approximately 0.1% to approximately 8%, from approximately 0.1% to approximately 5%, from approximately 0.1% to approximately 4%, from approximately 0.1% to approximately 3%, from approximately 0.1% to approximately 2%, from approximately 0.25% to approximately 10%, from approximately 0.25% to approximately 8%, from approximately 0.25% to approximately 5%, from approximately 0.25% to approximately 4%, from approximately 0.25% to approximately 3%, from approximately 0.25% to approximately 2%, from approximately 0.5% to approximately 10%, from approximately 0.5% to approximately 8%, from approximately 0.5% to approximately 5%, from approximately 0.5% to approximately 4%, from approximately from 0.5% to approximately 3%, from approximately 0.5% to approximately 2%, from approximately 0.75% to about 10%, from about 0.75% to about 8%, from about 0.75% to about 5%, from about 0.75% to about 4%, from about 0.75% to about 3%, or from about 0.75% to about 2% by weight, relative to the total weight of the composition.

[0080] In some embodiments, the compositions may be free or substantially free of one or more of the following: oxidizing agents, dyes or pigments for coloring hair, persulfates, peroxides, and / or ammonia. In still other embodiments, the compositions may comprise less than 5%, less than 4.5%, less than 4%, less than 3.5%, less than 3%, less than 2.5%, less than 2%, less than 1.5%, less than 1.25%, less than 1%, less than 0.75%, less than 0.5%, less than 0.4%, less than 0.3%, less than 0.2%, less than 0.1%, less than 0.05%, or less than 0.01% of a total amount of oxidizing agents, persulfates, peroxides, or ammonia, or of a total amount of any combination of two or more of these.

[0082] The pH of the composition is typically acidic, namely less than 7. For example, compositions may have a pH ranging from about 1 to about 7, such as from about 2.5 to about 6.5. In some embodiments, the compositions have a pH ranging from about 2.5 to about 5, from about 2.75 to about 4.75, from about 3 to about 4.5, or from about 3 to about 4. For example, the pH of the composition may be about 3, about 3.25, about 3.5, about 3.75, about 4, about 4.25, or about 4.5. II. KITS

[0083] The disclosure also relates to kits. In various embodiments, the compositions described herein are prepared by combining two separate compositions.For example, an embodiment may include a composition prepared by mixing a first composition comprising an organic acid and one or more additional components such as clays, surfactants, fatty compounds, thickening agents, amino acids and / or their salts, aminosulfonic acids and / or their salts, organic amine compounds, or combinations of two or more of these, and a second composition comprising a solvent and one or more additional components such as additional organic acids and / or their salts, clays, surfactants, fatty compounds, thickening agents, amino acids and / or their salts, aminosulfonic acids and / or their salts, organic amine compounds, or combinations of two or more of these, at the time of use or at a time close to it.

[0084] A non-limiting example of a kit could therefore include a first compartment or container comprising a first composition, and a second compartment or container comprising a second composition, in which the first and second compositions are mixed to form a composition according to the disclosure.

[0085] An example of a first composition for use in a kit may include one or more organic acids and / or their salts, and optionally one or more additional components, for example, clay compounds. Optionally, the first composition may be substantially anhydrous, for example, substantially powdery. The first composition may, for example, be packaged in a first compartment or container such as a sachet. The first compartment or container may optionally contain a pre-measured, single-use quantity of the first composition.

[0086] By way of non-limiting example, an embodiment of a first composition may include at least one organic acid and / or one of its salts, for example citric acid, ascorbic acid, erythorbic acid and / or their salts. The first composition may optionally include one or more additional components, for example clay compounds.

[0087] An example of a second composition for use in a kit may include a solvent, and optionally one or more additional components, for example, one or more additional organic acids and / or their salts, clays, surfactants, fatty compounds, thickening agents, amino acids and / or their salts, aminosulfonic acids and / or their salts, organic amine compounds, or combinations of two or more of these. Alternatively, a second composition may not include a solvent, but rather additional components to which water can be added by the user, in order to provide a composition containing a solvent.

[0088] By way of non-limiting example, an embodiment of a second composition may include at least one component selected from solvents, additional organic acids and / or one of their salts, for example ketoglutaric acid and / or one of its salts, surfactants, fatty compounds, thickening agents, amino acids and / or their salts, aminosulfonic acids and / or their salts, organic amine compounds, or combinations of two or more of these.

[0089] Optionally, the kits according to the disclosure may include one or more additional containers or compartments, for example with pre- and / or post-treatment compositions, shampoo compositions, conditioning compositions, and the like. The kits may also optionally include instructions, as well as tools for mixing and / or applying the compositions to the hair. III. PROCESSES

[0090] In various embodiments, the disclosure relates to processes for modifying the color, tone, and / or shade of hair. The compositions and processes can be used to remove some or all of certain dyes, while having minimal or no impact on other dyes. As such, the compositions can be intended to remove certain hair dyes to achieve the result desired by the consumer. For example, the processes may include processes for increasing the warmth of a hair color, for example, by targeting the removal of dyes that produce a cooler color. As a further example, the processes may include processes for increasing cool tones by targeting the removal of dyes that produce a warmer color.

[0091] It is understood by those skilled in the art that the color, tone, and shade of the hair are evaluated using the CIE L* a* b* system. In this system, the change in color, tone, and shade is determined by evaluating the hair color after treatment (L*2, a*2, b*2) against the hair color before treatment (L*ba*bb*i). The overall color change (AE) is defined by:

[0092] In this system, the three parameters represent, respectively, the color intensity (L*), the green / red color axis (a*) (for example, a higher a* is redder), and the blue / yellow color axis (b*) (for example, a higher b* is yellower). The higher the value of L*, the lighter the color; the higher the value of a*, the redder the color; and the higher the value of b*, the yellower the color. Furthermore, the higher the value of AE, the greater the difference in color between the treated hair and the hair before treatment. Thus, the processes may include modifying the color, tone, and / or shade of the hair by varying the values ​​of L*2, a*2, and / or b*2, and / or by increasing the AE value relative to the hair before treatment.

[0093] The compositions and processes are thus capable of obtaining a desired hair color, tone, and / or shade even without the application, or with minimal application, of subsequent hair coloring compositions. However, although the hair color, tone, and / or shade can be modified using the compositions and processes according to the disclosure, in at least some embodiments, the processes include an additional step of coloring or nunging the hair after the hair treatment according to the disclosure.

[0094] The disclosure further relates to processes for removing color from keratin fibers, particularly from hair that has been previously dyed, such as with an oxidative dye. In particular, the compositions and processes according to the disclosure are especially useful for removing darker hair colors that may otherwise be difficult to remove with traditional hair color removal compositions that do not use oxidizing agents. By way of non-limiting example, darker colors that can be removed in the processes according to the disclosure include blacks, ash browns, chestnuts, ash mochas, natural ash (blue or green), ash violets, violets, red violets, reds, red mochas, red chestnuts, mahogany, red coppers, coppers, and golds.

[0095] The processes include applying a composition as disclosed to keratin fibers, for example hair that has been previously dyed with at least one oxidative dye compound, optionally leaving the composition on the keratin fibers for a period of time (“processing period”, “application period”), and optionally rinsing or otherwise removing the composition from the keratin fibers.

[0096] The appropriate application time will be determined according to the color to be removed, and in various embodiments may last up to approximately 5 minutes, up to approximately 10 minutes, up to approximately 20 minutes, up to approximately 30 minutes, up to approximately 45 minutes, up to approximately 1 hour, up to approximately 2 hours, etc., such as from approximately 1 minute to approximately 60 minutes, from approximately 2 minutes to approximately 50 minutes, from approximately 5 minutes to approximately 45 minutes, or from approximately 10 minutes to approximately 40 minutes. It may be advantageous, in various embodiments, to leave the color-removing composition on the hair for at least approximately 15 minutes, and up to approximately 60 minutes. For example, the application time may range from approximately 15 minutes to approximately 60 minutes, from approximately 20 minutes to approximately 60 minutes, or from approximately 25 minutes to approximately 60 minutes.Optionally, the hair can be covered, for example with a treatment cap or aluminum foil, for at least part of the application period.

[0097] Optionally, the hair to which a composition according to the disclosure has been applied may be heated during the processing time. For example, the hair may be heated using a hair dryer, a hair dryer hood, or any other method for at least part of the processing time. The hair may be heated using temperatures above room temperature, for example, from about 27°C to about 90°C, from about 30°C to about 80°C, from about 35°C to about 70°C, or from about 40°C to about 50°C. For example, an example of a heating temperature range might be from about 40°C to about 45°C, such as from about 40°C to about 43°C.

[0098] In various embodiments, it may be advantageous to heat the treated hair for at least part of the processing time, or to leave it unheated for at least part of the processing time. For example, after applying the color-removing composition to the hair, the treated hair may be left to process for a period of time at room temperature, followed by a period of time with heat applied. As an alternative example, after applying the color-removing composition to the hair, the treated hair may be heated, followed by a period of time during which the hair is processed at room temperature.Other variations of these processes, consisting of alternating heating the treated hair and leaving the treated hair at room temperature, may be used, such as, for example, heating followed by room temperature followed by heating, or treatment at room temperature followed by heating followed by treatment at room temperature, and so on.

[0099] Surprisingly, the compositions and processes according to the disclosure effectively alter hair color and / or remove hair color without the use of oxidizing agents, persulfates, peroxides and / or ammonia, and without the damage that is typically associated with color removal compositions containing these components.

[0100] It should be understood that the compositions according to the disclosure are not hair coloring compositions. As such, the compositions are free or substantially free of dyes or pigments for coloring hair, in particular oxidative dye compounds. The compositions may optionally include a dye or pigment for coloring the composition, but it will be understood that the amount and / or type of dye or pigment will be chosen so as not to impart color to hair. Similarly, the processes according to the disclosure are not processes for imparting color to hair.

[0101] 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 should be understood that all definitions in this document are provided only within the meaning of this disclosure.

[0102] As used herein, the terms "comprising", "having" and "including" (or "comprehension", "having" and "include") are used in their open, non-limiting sense.

[0103] The expressions "one or more" and "at least one" are interchangeable and expressly include individual components as well as mixtures / combinations. Similarly, the expression "one of its / their salts" also refers to "its / their salts." Thus, when the disclosure refers to "at least one element selected from the group consisting of A, B, C, D, E, F, one of their salts or mixtures thereof," it indicates that one or more elements from A, B, C, D, and F may be included, that one or more salts from 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 that a mixture of any two elements from 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.

[0104] The expression "and / or" should be understood as including both conjunctive and disjunctive clauses. For example, "water and / or non-aqueous solvents" means "water and non-aqueous solvents" as well as "water or non-aqueous solvents", and expressly covers cases of either.

[0105] As used herein, the expressions "and their mixtures", "and one of their mixtures", "and one of their combinations", "or their mixtures", "or one of their mixtures", "or their combinations", and "or one of their combinations" are used interchangeably to indicate that the list of components immediately preceding the phrase, such as "A, B, C, D, or mixtures thereof", means that the component(s) can / 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 of their combinations.

[0106] For the purposes of this disclosure, it should be noted that, for the sake of conciseness, some of the quantitative expressions given herein are not qualified with 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 by a person skilled in the art, including approximations due to experimental and / or measurement conditions for that value.

[0107] All ranges and quantities stated herein are intended to include subranges and quantities using any disclosed point as a bound, and all bounds 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 understood to be modified by the term "approximately," whether or not this is expressly stated, unless expressly stated otherwise. Similarly, a given range of "approximately 1% to 10%" is understood to have its 1% and 10% bounds modified by the term "approximately." Unless expressly stated otherwise, "approximately" means + / - 5%. Likewise, all range bounds are understood to be disclosed individually, such that, for example, a range of 1:2 to 2:1 is understood to disclose a ratio of 1:2 and 2:1.

[0108] As used herein, 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 is in fact present in the composition, namely, present in an amount greater than 0%.

[0109] All quantities and ratios stated herein are given on a weight-for-weight basis, unless otherwise stated. Unless otherwise stated, all percentages stated herein are by weight of active ingredient.

[0110] As used herein, the expression "apply a composition to keratinous fibers," and its variations, is intended to mean bringing keratinous fibers, such as hair, into contact with at least one of the compositions in the disclosure, in any manner whatsoever. It may also mean bringing the keratinous fibers into contact with an effective amount of the composition.

[0111] 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 exhaustive. Salts also include a dissociated form of a compound, for example, in an aqueous solution.

[0112] Unless otherwise defined for any specific embodiment, the expression "substantially free" or "essentially free" as used herein means that there is less than about 5% by weight of a specific material added to a composition, relative to the total weight of the composition. For example, compositions may include less than about 4%, less than about 3%, less than about 2%, less than about 1.5%, less than about 1%, less than about 0.5%, less than about 0.1%, less than about 0.01%, less than about 0.001%, or less than about 0.0001% of the specified material.As such, it is envisaged that any component described herein for use in compositions may be present in the compositions in amounts less than approximately 5%, less than approximately 4%, less than approximately 3%, less than approximately 2%, less than approximately 1%, less than approximately 0.5%, less than approximately 0.1%, less than approximately 0.01%, less than approximately 0.001%, or less than approximately 0.0001%, and the composition shall be considered "substantially free" of such material. A composition that is "free" of a component is understood to be one that contains no amount of the specified component. However, it is understood that the expression "free" is used in the context of the composition. "Virtually free" refers to the amount of a component added to the composition, without including an amount of the component present in the composition as a minor component in a raw material. For example, a "wax-free" composition may not have wax included as an intended component, but may nevertheless contain a pigment that is coated with wax, because such a wax would be considered a minor component of the pigment material and would not be expected to provide the benefits to the composition that would be anticipated by including a wax itself as an intended component.

[0113] As used herein, the terms “treat,” “treated,” “treatment,” and their variations are not intended to be limiting, but rather are intended to simply indicate that one or more compositions is / are applied to the hair and possibly removed from the hair. For example, hair that is “treated” with a composition according to the disclosure may have had the composition applied, and / or may have had the composition applied and removed, for example, by rinsing or towel drying. As a further example, hair that is “treated” with a composition according to the disclosure may have had the composition applied, and / or may have had the composition applied and rinsed from the hair.

[0114] As used herein, the expressions "alter hair color," "hair color alteration," and their variations mean that the color, tone, and / or shade of the hair is changed by removing previously applied hair dyes from the hair. Furthermore, the expressions "color removal," "hair color removal," and their variations should be understood as referring to the removal of some or all of the hair dyes previously applied to the hair. It should be understood that the removal of artificial color may include the removal of all the color, or may include the removal of various shades of color.Therefore, in some embodiments, an overall change in hair color will be observed (e.g., greater AE), whereas in other embodiments, even if the overall color change is not considered significant, a variation in one or more of the L*, a*, or b* values ​​will be observed.

[0115] As used herein, "artificial color" means a color that has been imparted to the hair by means of a prior application of a composition capable of changing the color of the hair, for example with permanent, semi-permanent, or quasi-permanent hair dye compositions. In various embodiments, the artificial color that is removed from the hair is a color that has been imparted to the hair by one or more oxidative dye compounds.

[0116] As used herein, the expression "thiol-based" is used in its ordinary meaning to signify that the compound has an R-SH (thiol) group, where R is an alkyl group or other organic substituent.

[0117] The following examples are intended to illustrate embodiments of this disclosure but are not intended to be limiting. It will be obvious to those skilled in the art that various modifications and variations can be made to the compositions and processes of the invention without departing from the spirit or scope of the invention. EXAMPLES

[0118] The following examples are intended to be non-limiting and explanatory only. In the Examples, unless otherwise indicated, quantities are expressed as a percentage by weight (% by weight) of active substances, relative to the total weight of the composition.

[0119] In these examples, the change in hair color is evaluated using the CIE system L* a* b* using Colorshot MS, where the change is determined by evaluating the hair color after treatment (L*2, a*2, b*2) against the hair color before treatment (L*ba*bb*i).

[0122] Example 2 - Evaluation of hair color removal / color modification

[0123] The following studies were carried out to evaluate the effectiveness of the compositions as disclosed in removing color and changing the color, tone and / or shade of hair that has been previously dyed with oxidative hair dye compositions.

[0124] Strands of permed gray hair, approximately 90% gray, were colored with one of two commercially available oxidative hair dye compositions, each having different combinations of oxidative dye compounds (2 studies, 8 strands per study, 16 strands in total). The oxidative hair dye composition was mixed in a 1:1 ratio with 20V hydrogen peroxide developer to form a hair dye mixture, and the hair dye mixture was applied to the strands at a rate of approximately 3 grams per gram of hair. The strands were left in treatment at 27°C for approximately 35 minutes, rinsed, then washed with a commercial shampoo and rinsed again. The strands were then subjected to four additional shampoo / rinse cycles and then dried.

[0125] Once the strands were dry, seven out of eight strands in each study were treated as follows. One of the compositions 1A-1F or Cl was applied to one strand from each set at a rate of approximately 2 grams per gram of hair. After the strands were left in treatment for 30 minutes at 33°C, they were rinsed for approximately 30 seconds, washed with a commercial shampoo, rinsed again, shampooed again, rinsed again, and then dried. One strand per study was not treated with a color-removing composition and served as the color control.

[0126] The color of each strand was evaluated using the CIE L* a* b* system. Table 2 shows the AE values ​​for the treated strands, compared to the color control, and Table 3 shows the L*, a* and b* results. AE results measured

[0129] The results in Table 2 demonstrate that organic acids are effective in removing oxidative hair color. Comparative composition C2 includes thiolactic acid, a common color-removing agent, while none of compositions 1A-1F include thiol-based compounds. However, in some cases (compositions IC, 1D, 1F in Study 1 and compositions 1B-1F in Study 2), the compositions as disclosed were actually more effective at removing oxidative dyes than the traditional hair color-removal composition.

[0130] The results in Table 3 show that the compositions as disclosed can be used to modify the color, tone, and / or shade of hair in a controlled manner. For example, as shown in Study 1, compared to composition Cl, compositions IA and IB provide a darker tone (lower L* value), a more reddish tone (higher a* value), and compared to composition IB, composition IA provides a lighter tone (higher L* value), a less reddish tone (lower a* value).

[0131] These data demonstrate that organic acids can be used to modify hair color in a targeted manner, unlike traditional hair color removal compositions. The compositions according to the disclosure have the unique ability to fade and deliver the desired color, tone, and / or shade(s), even without subsequent hair coloring applications.

[0132] Example 3 - Additional evaluation of hair colour removal / colour modification

[0133] The hair dyeing process of Example 2 was repeated with a different commercially available oxidative hair dye composition (5 strands). One of the compositions IA, IC, 1F, or Cl was applied to separate strands at a rate of approximately 2 grams per gram of hair. After the strands were left to process for 30 minutes at 33°C, they were rinsed for approximately 30 seconds, washed with a commercial shampoo, rinsed again, shampooed again, rinsed again, and then dried. One strand was not treated with a color-removing composition and served as the color control.

[0134] The color of each strand was evaluated using the CIE L* a* b* system. Table 4 shows the AE values ​​for the treated strands, relative to the color control, and Table 5 shows the L*, a*, and b* results. Measured AE results

[0137] Similar to the data in Example 2, the results in Tables 4 and 5 confirm that organic acids are effective in removing oxidative hair color, and can be used to change hair color in a controlled manner, altering the color, tone and / or shade of the hair. Example 4# - Additional Compositions

[0138] Compositions 2A to 2D can also be prepared as shown in Table 6, and are also intended to provide similar benefits of hair color removal and / or modification.

[0139] [Tableauxô] 2A 2B 2C 2D Ascorbic Acid 80.0 50.0 Erythorbic Acid 10.0 35.0 Alpha-Ketoglutaric Acid 10.0 5.0 Arginine 2.5 Betaine 1.9 Proline 0.5 Xanthan Gum 0.7 0.7 Hydroxypropyl Cellulose 1.5 1.0 Bentonite 1.0 Kaolin 3.0 Ethanolamine 3.7 1.0 Aminomethyl Propanol 4.5 Sodium Lauryl Sulfate 5.0 5.0 Sodium Lauryl Methyl Isethionate 2.5 7.5 Fatty Compounds (silicone oils or vegetable oils) 1.5 5.0 Additives (perfumes, concealer) pH, vitamins, plant extracts, preservatives, etc.) <5 <5 <5 <5 Solvents (water and non-aqueous solvents) Qs per 100 Qs per 100 Qs per 100 Qs per 100

[0140] The above examples demonstrate that the compositions and processes according to the disclosure effectively remove various oxidative hair dyes from hair, making it possible to change the color, tone and / or shade of hair in a controlled manner.

[0141] These compositions and processes are unique in that they can offer a targeted method for removing hair color to provide consumers with choices of resulting color, even without the need for color touch-ups to achieve the desired result. The compositions and processes can be particularly useful when a similar tone, rather than an entirely different hair color, is desired, as demonstrated by the data in the Examples above.

[0142] Moreover, the Examples show that the compositions and processes are particularly useful for removing darker colors, which tend to be more difficult to remove with color-removing agents that are not oxidizing agents.
