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, add warmth or coolness to their hair color, 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 small oxidative dye molecules to penetrate. in the cuticle and 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 remove essentially 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, called "filling. "Coloring 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.Thus, 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 hair treatment processes with pre- and / or post-treatment compositions allow for the controlled removal of artificial color from previously dyed hair, providing desired modifications to hair color, tone, and / or shade. The compositions are unique in that they can therefore 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 filling step. Furthermore, these processes significantly enhance the overall color removal performance of hair color removal compositions. Finally, because the compositions are free or substantially free of oxidizing agents, the hair damage typically associated with hair color removal compositions and processes can be minimized or eliminated.

Non-limiting examples include preservatives, fragrances such as perfumes, pH adjusters, salts, antioxidants, vitamins (e.g., ascorbic acid, tocopherol), vitamin derivatives, botanical extracts, buffers, sequestering agents, and the like. In some embodiments, hair color removal compositions are free or substantially free of any of the aforementioned components; for example, the compositions may be free or substantially free of antioxidants, free or substantially free of ascorbic acid, etc.

[0111] The total amount of auxiliary components, if any, typically ranges from about 0.01% to about 15%, relative to the total weight of the hair color removal 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 0.5% to about 3%, from about 0.5% to about 2%, from about 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.

[0112] In some embodiments, hair colour removal compositions may be free or substantially free of one or more of the following: ascorbic acid and its salts, dyes or pigments for colouring 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 ascorbic acid and its salts, persulfates, peroxides or ammonia, or a total amount of any combination of two or more of these.

[0115] The disclosure also relates to kits. In various embodiments, the processes for removing color and / or modifying the color, tone, and / or shade of hair include the application of a pre- and / or post-treatment composition to the hair in conjunction with the application of a hair color removal composition to the hair. As such, a non-limiting example of a kit could include a first compartment or container comprising a pre- and / or post-treatment composition as disclosed, and a second compartment or container comprising a hair color removal composition.

[0116] Optionally, the kits as disclosed may include one or more additional containers or compartments, for example with 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

[0117] In various embodiments, the disclosure relates to processes for modifying the color, tone, and / or shade of hair. The compositions and processes may be used to remove some or all of certain dyes, while having minimal or no impact on other dyes. As such, the compositions may 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.

[0118] It is understood by a person skilled in the art that the color, tone, and shade of hair are evaluated using the CIE L* a* b* system. In this system, the change in color, tone, and / or shade is determined by evaluating the color hair color after treatment (L*2, a*2, b*2) compared to hair color before treatment (L*ba*bb*i). The overall color change (AE) is defined by: ~~ L t) 2 + H “ <> 2 + -&î) 2

[0119] 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.

[0120] 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.

[0121] The disclosure also relates to processes for removing artificial color from keratin fibers, including hair that has been previously dyed 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.

[0122] The processes according to the disclosure include the use of treatment compositions according to the disclosure before, during, or after a hair color removal composition has been applied to the hair. Thus, the processes may be hair pretreatment processes, processes of post-treatment of hair and / or hair treatment processes during a color removal process.

[0123] Examples of pretreatment processes include (i) applying a treatment composition as disclosed to keratin fibers, for example, hair that has been previously dyed with at least one oxidative dye compound, and optionally leaving the treatment composition on the keratin fibers for a period of time (“processing time” or “processing time”), and (ii) subsequently applying a hair color-removing composition to the keratin fibers, and optionally leaving the hair color-removing composition on the keratin fibers for a period of time. The hair may be rinsed and / or shampooed after step (ii), but preferably, the hair is not rinsed and / or shampooed between steps (i) and (ii).

[0124] Examples of post-treatment processes include (i) applying a hair color-removing composition to keratin fibers, for example, hair that has been previously dyed with at least one oxidative dye compound, and optionally leaving the hair color-removing composition on the keratin fibers for a period of time, and (ii) applying a treatment composition as disclosed to the keratin fibers, and optionally leaving the treatment composition on the keratin fibers for a period of time. The hair may be rinsed and / or shampooed after step (ii), but preferably, the hair is not rinsed and / or shampooed between steps (i) and (ii).

[0125] Other examples of processes including the use of treatment compositions as both pretreatment and posttreatment. For example, such a process may include (i) applying a treatment composition as disclosed to keratin fibers, optionally leaving the treatment composition on the keratin fibers for a period of time, (ii) subsequently applying a hair color removal composition to the keratin fibers, optionally leaving the hair color removal composition on the keratin fibers for a period of time, and (iii) subsequently applying a treatment composition as disclosed to the keratin fibers, optionally leaving the treatment composition on the keratin fibers for a period of time.The hair may be rinsed and / or washed with shampoo after step (iii), but preferably, the hair is not rinsed and / or washed with shampoo between steps (i), (ii), and / or (iii). It should be understood that in such embodiments, the pretreatment and posttreatment compositions may be the same or different.

[0126] Other examples of methods include applying a treatment composition as disclosed to keratin fibers substantially simultaneously with the application of a hair color removal composition to the keratin fibers. For example, this may include layering the treatment composition and the hair color removal composition on the hair.

[0127] The appropriate application time for both the treatment composition and the hair color removal composition will be determined according to the color to be removed, and may, in various embodiments, 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 treatment and / or hair color removal composition on the hair for at least approximately 15 minutes, and up to approximately 60 minutes.For example, the application time can 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 time.

[0128] Optionally, hair to which a hair color treatment and / or removal composition as disclosed 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, a heating temperature range may be from about 40°C to about 45°C, such as from about 40°C to about 43°C.

[0129] In various embodiments, it may be advantageous to heat the treated hair for at least part of the processing time, or without heating for at least part of the processing time. For example, after applying the hair color treatment and / or removal 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 treatment composition and / For hair color removal, the treated hair may be heated, followed by a period of time during which the hair is treated at room temperature. Other variations of these processes, alternating heating the treated hair with leaving it 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.

[0130] 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.

[0131] It should be understood that the hair color treatment and modification compositions disclosed herein 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 shall be understood that the amount and / or type of dye or pigment shall be chosen so as not to impart color to the hair. Similarly, the processes disclosed herein are not processes for imparting color to hair.

[0132] 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 for this disclosure.

[0133] As used herein, the terms "comprising", "having" and "including" (or "comprehension", "having" and "include") are used in their open, non-limiting sense.

[0134] 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 item selected from the group consisting of A, B, C, D, E, F, a salt of these, 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. of F may be included, or a mixture of any two of A, B, C, D, E, F, one or more salts of A, one or more salts of B, one or more salts of C, one or more salts of D, one or more salts of E and one or more salts of F may be included.

[0135] 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.

[0136] As used herein, the expressions "and their mixtures", "and one of their mixtures", "and their combinations", "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 expression, such as "A, B, C, D, or their mixtures", means that the component(s) may be chosen from A, B, C, D, from A + B, from A + B + C, from A + D, from A + C + D, etc., without limitation as to their variations. Thus, the components may be used individually or in any combination thereof.

[0137] 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 that would be reasonably deduced by a person skilled in the art, including approximations due to the experimental and / or measurement conditions for that value.

[0138] All ranges and quantities stated herein are deemed to include subranges and quantities using any disclosed point as a bound, and all bounds are deemed 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 deemed to encompass ranges of "1% to 8%", "1% to 5%", "2% to 10%", and so on. All numbers, quantities, ranges, etc., are deemed to be modified by the term "approximately", whether or not expressly stated, unless expressly stated otherwise. Similarly, a given range of "approximately 1% to 10%" is deemed to have its bounds of both 1% and 10% modified by the term "approximately". The term "approximately" is used here to indicate a difference of up to + / - 10% from the stated number, such as + / - 9%, + / - 8%, + / - 7%, + / - 6%, + / - 5%, + / - 4%, + / - 3%, + / - 2%, or + / - 1%.Unless expressly stated otherwise, "approximately" means + / - 5%. Similarly, all range boundaries are understood to be disclosed individually, in such a manner. that, for example, a range of 1:2 to 2:1 is understood as disclosing a ratio of 1:2 and 2:1.

[0139] As used here, if a component is described as being present "in an amount up to" a certain amount, it is expected that this component is actually present in the composition, i.e., present in an amount greater than 0%.

[0140] All quantities and ratios herein are given on a weight-for-weight basis, unless otherwise stated. Unless otherwise stated, all percentages given herein are by weight of active ingredient.

[0141] As used herein, the expression "applying 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.

[0142] 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.

[0143] 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 quantities 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 quantity of the specified component. However, it is understood that the terms "free" and "substantially free" refer to the quantity of a component added to the composition, without including a quantity 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 a wax, because such a wax. would be considered a minor component of the pigment material and should not provide benefits to the composition that would be expected by including a wax in itself as an intended component.

[0144] As used herein, the terms “treat,” “treated,” “treatment,” and variations thereof are not intended to be restrictive, but rather are intended to indicate simply 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.

[0145] 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.

[0146] 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.

[0147] 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.

[0148] The following examples are intended to illustrate ways in which this disclosure may be implemented, but are not exhaustive. It will be obvious to the person of the craft that various modifications and variations can be made in the compositions and processes of the invention without departing from the spirit or scope of the invention.

[0154] Example 2 - Evaluation of hair colour removal / colour modification

[0155] 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.

[0156] Studies using three different commercially available oxidative hair color compositions, each with different combinations of oxidative dye compounds, were conducted as follows. Strands of ~90% gray, permed hair were colored by mixing the dye composition, in a 1:1 ratio, with a 20V hydrogen peroxide developer to form a hair dye mixture. 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 dried. Once the strands were dry, all but one strand in each color study was treated as follows.One sample per color was not subjected to a color-eliminating composition application and served as the color control for this study.

[0157] One-step process: One of the compositions IA and IB, RI and R2, Cl or C4 was applied to separate dyed strands at a rate of approximately 2 grams per gram of hair. After leaving the strands in treatment for 30 minutes at approximately 33°C, the strands were then rinsed for approximately 30 seconds, washed with a commercial shampoo, rinsed again, shampooed again, rinsed again, and then dried.

[0158] One-step application, repeated: The one-step process was followed with compositions RI or R2, but with a second application of the hair color removal composition once the one-step process was completed.

[0159] Two-step process: One of the treatment compositions IA or IB, or one of the comparative compositions C2, C3 or C4, was applied to separate dyed strands before or after the hair color removal compositions RI or R2. In each case, the hair color removal compositions and the treatment and comparison compositions were left in treatment for 30 minutes at approximately 33°C. When treatment compositions IA or IB, or comparison compositions C2, C3 or C4 were used as a pretreatment, the strands were not rinsed before the application of RI or R2; however, once the treatment time of RI or R2 was completed, the strands were rinsed for approximately 30 seconds, washed with a commercial shampoo, rinsed, shampooed again, rinsed again, and then dried.When treatment compositions IA or IB, or comparative compositions C2, C3 or C4 were used as post-treatment, the strands were not rinsed after the application of RI or R2, but once the processing time was completed for treatment compositions IA or IB, or comparative compositions C2, C3 or C4, the strands were rinsed for approximately 30 seconds, washed with a commercial shampoo, rinsed, shampooed again, rinsed again, and then dried.

[0160] Once the above processes were completed and the strands were dry, the color of each strand was evaluated using the CIE L* a* b* system. Tables 2A to 2C show the AE values ​​for the treated samples, relative to the color control, and the L*, a* and b* results for each study.

[0166] TABLE 2C - Results: Color Study 3

[0167] The results in Tables 2A to 2C demonstrate that the use of treatment compositions as disclosed results in a greater overall color change (greater AE). These results are surprising because they show that using the treatment compositions as pre- and / or post-treatment compositions has a greater capacity to remove hair color than including the same amount of organic amine compound in the hair color removal composition, as shown by a comparison of Study 1-3 with Studies 1-8 and 1-9, a comparison of Study 2-4 with Studies 2-10 and 2-11, and a comparison of Study 3-4 with Studies 3-9 and 3-10. These results are also surprising because they demonstrate that the use of the compositions treatment compositions as pre- and / or post-treatment have a greater capacity to remove hair color than the use of other pre- and / or post-treatment compositions such as an oxidizing composition, as shown by a comparison of study 2-9 with study 2-11 and a comparison of study 2-10 with study 2-12.

[0168] Furthermore, the results show that the color, tone, and / or shade of hair can be modified in a controlled manner using compositions and processes as disclosed. For example, as shown in Study 3, compared to the hair color removal composition study 3-2, which provides approximately the same overall color change (AE), the process in Study 3-8 produces a more reddish and less yellow tone (higher a* value and lower b* value).

[0169] These data demonstrate that the compositions and processes as disclosed can be used to modify hair color in a targeted manner, unlike traditional hair color removal compositions. The compositions and processes as disclosed have the unique ability to fade and deliver the desired color, tone, and / or shade(s), even without subsequent hair coloring applications.

[0170] Example 3 - Additional treatment compositions

[0171] Treatment compositions 2A to 2D can also be prepared as shown in Table 3, and are also expected to provide similar hair color removal and / or modification benefits when used in processes according to disclosure.

[0173] TABLE 3

[0174] 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.

[0175] 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 to fill in the color 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.

[0176] In addition, 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.
