Description

Title of the invention: COMPOSITIONS AND METHOD 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 the color of their hair. 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 include permanent, semi-permanent, and temporary hair dyeing.

[0003] 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 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, permanently altering the hair color.

[0004] On the other hand, temporary hair dye compositions typically use pigments, oil-soluble dyes, or direct dyes that are deposited on the hair fiber to impart color to the hair. Temporary hair dyes are removed from the hair by washing after one or two shampoo cycles.

[0005] Between permanent and temporary dyes, we find semi-permanent hair dyes. Semi-permanent dyes can last longer than temporary dyes, but not as long as permanent dyes, and typically last for four to twelve shampoo cycles. Although semi-permanent dyes are ideal for changing hair color in a lasting but not permanent way, these products present problems when a person wants to change their hair color before it fades over time. For example, if a person who has already changed the color or tone of their hair with a first semi-permanent dye composition wants to change the color or tone of their already colored hair, the first dye must be removed or neutralized so that it no longer imparts the first color to the hair fiber.

[0006] If a person who has already changed the color or tone of their hair with a semi-permanent dye composition wishes to change the color or tone of their already colored hair, some or all of the color imparted by the first semi-permanent dye composition must be removed or neutralized so that it no longer imparts the first color to the hair fiber. For example, a consumer may wish to remove the first color or tone to return to their natural hair color, or obtain a second color different from the first by using a second 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 dye compounds in the initial dye formulation and the desired second color or tone, different levels and types of color removal are required.

[0007] 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 brittle, fragile, and giving it an unhealthy appearance. Given the damage caused by these compositions, they are not typically used to remove semi-permanent hair dyes. Furthermore, these compositions can remove essentially all of the hair color; therefore, the subsequent application of a second dye composition is necessary to achieve the desired second color or tone. This step, called a color "touch-up," can further expose the hair to harsh chemicals and lead to additional damage.

[0008] A second option involves the use of compositions with reducing agents, such as thiol-based compounds. However, these compositions are not very effective at removing semi-permanent hair dyes; 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.

[0009] Furthermore, if an individual wishes to remove only semi-permanent dyes without also removing permanent (oxidative) dyes, neither oxidizing agents nor thiol-based color-removing agents can achieve the desired result since both are known to remove oxidative dye from hair.

[0010] It has now been discovered, surprisingly, that compositions comprising clay compounds allow for the controlled removal of semi-permanent dyes from previously dyed hair, making it possible to modify the desired 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. SUMMARY

In various embodiments, the compositions and processes can remove some or all of certain dyes, while having minimal or no impact on other dyes.

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.

[0079] In certain embodiments, the compositions may be free or essentially free of components traditionally used to remove hair color, such as oxidizing and / or reducing agents. As For example, the composition may be free or substantially free of cysteine, homocysteine, thiolactic acid, thiosalicylic acid, thioglycolic acid, glutaric acid, glyoxylic acid, glycolic acid, citric acid, ascorbic acid, their salts, and / or their derivatives. In some embodiments, the compositions are free or substantially free of thiol-based color-eliminating agents, such as thiolactic acid, thiosalicylic acid, thioglycolic acid, and / or their salts.In various embodiments, if any of the aforementioned components is included, 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 any of these components or of a total quantity of these components combined.

[0080] The compositions can be in any suitable form. For example, the compositions can be a liquid, a gel, a cream-gel, a cream, a serum, etc. Advantageously, the compositions can be used as a one-part hair color removal composition, as opposed to known hair color removal systems that require the application of several compositions to effectively remove hair color. In particular, the compositions are stable for at least 24 hours, at least 48 hours, at least 72 hours, at least one week, at least two weeks, at least four weeks, at least two months, at least six months, or at least one year, unlike known removal agent compositions that require mixing with water or a developer immediately before use due to their unstable nature.

[0081] In various embodiments, the viscosity of the compositions can be greater than about 500 cP and less than about 2500 cP, for example it can range from about 800 to about 2000 cP, such as from about 1000 to about 1800 cP, or from about 1200 to about 1600 cP when measured using a Rheomat with an M3 spindle at about 25 °C, for a period of about 30 seconds.

[0082] The pH of the compositions can range from about 5 to about 11, such as from about 6 to about 10, from about 6.5 to about 9.5, from about 7 to about 9, from about 7.5 to about 8.5, or can be about 8. For example, the pH of the composition can be about 6, about 6.5, about 7, about 7.5, about 8, about 8.5, about 9, about 9.5 or about 10. II. PROCESSES

[0083] In various embodiments, the disclosure relates to processes for modifying the color, tone, and / or shade of hair. The compositions These processes can be used to remove some or all of certain semi-permanent hair dyes, while having minimal or no impact on other dyes. As such, the compositions can be designed to remove specific hair dyes to achieve the consumer's desired result. For example, the processes may include methods for increasing the warmth of a hair color, such as by targeting the removal of dyes that produce a cooler color. As a further example, the processes may include methods for enhancing cool tones by targeting the removal of dyes that produce a warmer color.

[0084] 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 / or 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: A* = - L*)2 + (4 - a*)2 + (3 / 4 - 6*)2

[0085] 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.

[0086] 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 shading the hair after the hair treatment according to the disclosure.

[0087] The disclosure also relates to processes for removing artificial color from keratin fibers, particularly hair that has been previously dyed with a semi-permanent dye. In particular, the compositions and processes described in the disclosure are especially useful for removing darker colors. Hair 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 as disclosed 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. The processes also include the removal of semi-permanent color from hair that has been dyed with both semi-permanent and permanent (oxidative) dyes. The processes allow for the removal of semi-permanent dyes without removing the color imparted by the oxidative dyes.

[0088] The methods include applying a composition as disclosed to keratin fibers, for example, hair that has been previously dyed with at least one semi-permanent hair dye compound, optionally leaving the composition on the keratin fibers for a period of time (“processing time” or “application time”), and then rinsing or otherwise removing the composition from the keratin fibers. Thus, the methods may include a two-step process, which is simpler and more efficient than known three-step or more-step processes where multiple compositions are applied to the hair for color removal before rinsing.

[0089] The appropriate application time will be determined according to the color to be removed, and in various embodiments may last up to approximately 60 minutes, up to approximately 90 minutes, up to approximately 120 minutes, up to approximately 150 minutes, up to approximately 180 minutes, etc., such as from approximately 10 minutes to approximately 6 hours, from approximately 30 minutes to approximately 3 hours, from approximately 45 minutes to approximately 150 minutes, or from approximately 60 minutes to approximately 2 hours. It may be advantageous, in various embodiments, to leave the color-removing composition on the hair for at least approximately 30 minutes, and up to approximately 3 hours. For example, the application time may range from approximately 30 minutes to approximately 180 minutes, from approximately 45 minutes to approximately 150 minutes, or from approximately 60 minutes to approximately 120 minutes.Optionally, the hair can be covered, for example with a treatment cap or aluminum foil, for at least part of the application period.

[0090] In certain embodiments, the hair onto 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 during 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, or from about 30°C to approximately 80°C, from approximately 35°C to approximately 70°C, or from approximately 40°C to approximately 50°C. For example, a heating temperature range could be from approximately 40°C to approximately 45°C, such as from approximately 40°C to approximately 43°C.

[0091] 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 such processes of alternating heating of treated hair and leaving hair in treatment 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.

[0092] Unexpectedly, the compositions and processes according to the disclosure effectively remove semi-permanent hair color without the use of traditional color-removing agents such as oxidizing and reducing agents, without the damage that is typically associated with color-removing compositions containing oxidizing agents, and without the odor that is typically associated with color-removing compositions containing thiol-based compounds.

[0093] In certain embodiments, it may be advantageous to perform the processes described herein more than once in order to achieve the desired level of color removal. Since the compositions minimize hair damage and have a reduced odor compared to known color-removing compositions, consumers are able to achieve the desired color removal without the drawbacks associated with such known compositions.

[0094] 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, including semi-permanent or 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 the hair. Even so, the processes according to the disclosure are not processes for imparting color to hair.

[0095] 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.

[0096] As used herein, the terms "comprising", "having" and "including" (or "comprehension", "having" and "include") are used in their open, non-limiting sense.

[0097] The expressions "one or more" and "at least one" are interchangeable and expressly include individual components as well as mixtures / combinations. Similarly, the expression "a salt of it" also refers to "salts of it". 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 of these", it indicates that one or more of A, B, C, D and F may be included, one or more of a salt of A, a salt of B, a salt of C, a salt of D, a salt of E and a salt of F may be included, or a mixture of any two of A, B, C, D, E, F, 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.

[0098] 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.

[0099] 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.

[0100] For the purposes of this disclosure, it should be noted that, in order to provide a more concise description, some of the quantitative expressions given in the This document does not qualify with the term "approximately". It is understood, whether the term "approximately" is used explicitly or implicitly, that each quantity given herein is intended to refer to the actual value given, and it is also intended to refer to the approximation of that given value that would be reasonably deduced by a person skilled in the art, including approximations due to experimental and / or measurement conditions for that given value.

[0101] 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, such that, for example, a range of 1:2 to 2:1 is understood to disclose a ratio of 1:2 and 2:1.

[0102] 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%.

[0103] 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.

[0104] 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.

[0105] 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.

[0106] Unless otherwise defined for any specific embodiment, the expression "substantially free" or "essentially free" as used here means that there is less than approximately 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 approximately 4%, less than approximately 3%, less than approximately 2%, less than approximately 1.5%, 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% of the specified material. As such, it is envisaged that any component described herein for use in compositions may be present in compositions in amounts less than about 5%, less than about 4%, less than about 3%, less than about 2%, 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%, and the composition shall be regarded as "substantially free" from such material.A composition that is "free" of a component is understood to mean that it 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 composition "free" of waxes may not have wax included as an intended component, but may nevertheless contain a pigment that is coated with wax, since such a wax would be considered a minor component of the pigment material and should not provide the benefits to the composition that would be expected from including a wax itself as an intended component.

[0107] 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 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 another 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.

[0108] 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 color. hair dyes previously applied to the hair. It should be understood that the removal of artificial color may include the removal of the entire color, or may include the removal of various color tones. Therefore, in some embodiments, an overall change in hair color will be observed (e.g., higher 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.

[0109] 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 semi-permanent dye compounds.

[0110] As used herein, the expressions "odorless", "minimal odor", "odorless", "reduced odor" or similar are intended to refer to the odor that is typically associated with color-removing compositions containing thiolactic acid-based color removers, an odor that hair coloring professionals and consumers typically find acrid and / or nauseating.

[0111] The term "stable" as used here means that no phase separation is observed when the composition is stored at room temperature and room pressure for the specified period of time.

[0112] 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

[0113] 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.

[0114] 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). The color change (AE) is calculated as follows: = vte - w 2 + ( < -+b - W

[0123] Example 2 - Evaluation of the removal of semi-permanent hair color

[0124] The following studies were conducted to evaluate the efficacy of the compositions disclosed for removing color and changing the color, tone, and / or shade of hair previously dyed with semi-permanent hair dyes. The dyes used in the studies are listed in Table 2A.

[0126] Example 2A - Removal of semi-permanent hair dyes: 60 minutes, single application

[0127] Three sets of hair strands were colored with one of three different commercially available semi-permanent hair dye compositions (DI to D3) (21 strands in total, 9 strands for DI and 6 strands for each of D2 and D3). Before the dyeing step, all but one of the strands were platinum bleached, with the last strand being permed, resulting in approximately 90% gray hair. The dye compositions were applied to dry strands at a rate of approximately 3 grams per gram of hair. The strands were left in the treatment at 27°C for 35 minutes, rinsed, and dried. Once dry, the strands were treated as follows.

[0128] Four strands from each set were treated with compositions as disclosed. One of compositions IA to IC or 1E was applied to one strand from each set at a rate of approximately 2 grams per gram of hair. After leaving the strands in treatment for 60 minutes at 33°C, the strands were rinsed, followed by three shampoo / rinse cycles using a commercial shampoo, and then dried.

[0129] One strand per set was treated with the comparative composition C3. Just before use, 28 grams of composition C3 were mixed with 75 ml of a commercially available 30V developer composition. The mixture was applied to the strands at a rate of approximately 2 grams per gram of hair. After leaving the strands in treatment for 60 minutes at 33°C, the strands were rinsed, followed by three shampoo / rinse cycles using a commercial shampoo, and then blow-dried.

[0130] Three strands from the set dyed with composition DI were treated with comparative compositions Cl, C2, or C4, as follows. Just before use, 20 grams of composition C4 were mixed with 4 ounces of water at room temperature and the mixture was shaken according to the package instructions to form a mixture with a pH of approximately 2.5. Approximately 2 grams of mixture C4, composition Cl, or composition C2 were applied to one of the strands per gram of hair, with mixture C4 being applied to the permed strand. The strands treated with compositions Cl and C2 were then left in treatment for 60 minutes, and the strand treated with mixture C4 was left in treatment for 45 minutes, all at a temperature of approximately 33°C. After the treatment time, the strands were rinsed, followed by three cycles shampoo / rinse using a commercial shampoo, then blow-dried.

[0131] One strand per set was not subjected to an application of color-eliminating composition and constituted the color control.

[0132] The color of each strand was then evaluated using the CIE L* a* b* system to assess the effectiveness of color removal after 60 minutes with a single application of the hair color removal compositions. Table 2B shows the AE values ​​for the treated strands, compared to the color control, and Table 2B shows the L*, a*, and b* results.

[0136] TABLE 2C - Measured L*a*b* results: 60 minutes, single application

[0137] The results in Table 2B demonstrate that the compositions according to the disclosure are effective in removing semi-permanent hair dyes from hair. For example, for the Dl dye composition, compositions IA, IB, and 1E resulted in a greater overall color change (higher AE) compared to all compositions Cl to C4, with IC being better than Cl and C4.

[0138] The results in Table 2C 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 by the results for dye composition D1, although composition IC had a less overall color change than composition C2, composition IC provided a more reddish tone (higher a* value) compared to composition C2. Similarly, as shown by the results for dye composition D2, although composition IB produced a lighter shade (higher L* value) than composition IC, composition IC produced a more reddish tone (higher a* value) than composition IB.

[0139] 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 as disclosed have the unique ability to fade and deliver the desired color, tone, and / or shade(s), even without subsequent hair coloring applications.

[0140] Example 2B - Removal of semi-permanent hair color: 120 minutes, single application

[0141] The process of Example 2A was repeated with composition IA, but with a longer processing time (120 minutes) for the strands dyed with the semi-permanent hair dye compositions Dl and D3. The AE values ​​for the treated strands, relative to the color control, are shown in Table 2D, and the L*, a* and b* values ​​for the treated strands are shown in Table 2E.

[0165] Studies in Example 2 show that compositions containing clay compounds as color-removing agents are effective in removing semi-permanent hair dyes.

[0166] Example 3 - Evaluation of color removal on oxidative dyes

[0167] The following studies were carried out to evaluate the benefits of eliminating color using compositions according to the disclosure on oxidative hair dyes.

[0168] Three strands of hair were colored with a commercially available oxidative hair dye composition. 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 to process at 27°C for 35 minutes, rinsed, washed with a commercial shampoo, and rinsed again. The strands were then subjected to four additional shampoo / rinse cycles and left to air dry.

[0169] Once the strands were dry, two of them were treated as follows. Composition IA was applied to one strand at a rate of approximately 2 grams per gram of hair and left to act for 60 minutes at 33°C. Composition Cl The solution was applied to a second strand at a rate of approximately 2 grams per gram of hair and left to process for 30 minutes at 33°C. Once the processing time was complete, the strands were rinsed for approximately 30 seconds, washed with a commercial shampoo, rinsed again, washed again with shampoo, rinsed once more, and then blow-dried. One strand per set was not treated with the color-removing solution and served as the color control.

[0170] The color of each strand was then evaluated using the CIE L* a* b* system to assess the effectiveness of the color removal. Table 3 presents the AE values ​​for the treated strands, compared to the color control.

[0171] [Tables 15] AE Control - Cl 52.1 IA 1.45 TABLE 3 - Measured AE Results

[0172] The results in Table 3A confirm that an oxidative hair dye can be removed with composition Cl containing thiolactic acid as a color remover, whereas composition IA according to the disclosure does not remove oxidative dyes practically at all.

[0173] Example 3 therefore demonstrates that the compositions according to the disclosure can be used to remove semi-permanent hair dyes with minimal impact on a color conferred by oxidative dyes. Example 4# - Additional Compositions

[0174] Compositions 2A to 2D can also be prepared as indicated in Table 4, and are also expected to offer similar benefits in terms of hair colour removal and damage reduction.

[0176] TABLE 4

[0177] The examples above demonstrate that the compositions and processes according to the disclosure effectively remove semi-permanent hair dyes from hair, making it possible to change the color, tone and / or shade of hair in a controlled manner.

[0178] 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.

[0179] 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.
