Description

Title of the invention: HAIR TREATMENT COMPOSITIONS AND METHODS technical field

[0001] The disclosure relates to cosmetic compositions and hair treatment processes, in particular for permanently altering hair color. The compositions and processes provide excellent hair coloring / lightening benefits and also have the added benefit of reducing and / or preventing hair damage and maintaining hair strength and the integrity of hair fibers. CONTEXT

[0002] Consumers wish to use cosmetic compositions and processes to change or improve the appearance of their hair, for example, by altering the color, style, and / or shape of the hair, and / or by imparting various properties to the hair, such as shine and revitalization. However, many compositions and processes for altering the appearance of hair, such as permanent hair color modification compositions and processes, involve harsh chemical treatments. For example, hair color modification compositions and processes generally require the presence of harsh chemical compounds, such as oxidizing agents. In order to change the hair color, these components must first break down the natural components of the hair fibers.

[0003] It is known that, although such processes effectively alter hair color, the chemical agents used inherently cause hair damage and negatively impact the strength, elasticity, and porosity of the hair fibers. For example, hair that has been bleached, dyed, etc., is often dry, frizzy, and generally appears unhealthy to the touch and in appearance. Furthermore, damaged hair is brittle and / or exhibits increased elasticity, leading to more frequent breakage. As such, consumers seek compositions and processes to prevent or minimize such damage and / or to repair hair that has been damaged by these treatments and processes.In particular, consumers want strong hair that does not break easily, that can be stretched or manipulated while retaining the ability to return to its original state without breakage (i.e., has reduced elasticity), that is soft and healthy to the touch, and that also has a shiny and healthy appearance.

[0004] However, it has proven difficult to formulate compositions that satisfactorily meet these requirements. For example, some compositions that attempt to solve the problem simply coat the hair with compounds that may improve its feel and appearance; however, this approach is only temporary and superficial. Rather than preventing or repairing hair damage, this approach merely masks the damage until the next rinse or wash. Other compositions attempt to treat the damage within the hair fiber, but have not been satisfactory to date.

[0005] The present inventors have now discovered a synergistic combination of components that is remarkably effective in preventing or minimizing hair damage while providing excellent coloring and / or lightening effects to the treated hair. Hair treated with compositions according to the disclosure shows remarkably reduced signs of damage, including increased strength and / or reduced elasticity. SUMMARY

Other components are often present in the oxidizing composition, for example, surfactants, particularly nonionic surfactants, rheology modifiers, chelators, fatty substances, ceramides, pH adjusters, preservatives, etc. In addition, other oxidizing agents may be present in addition to or instead of hydrogen peroxide, such as those described above, and non-aqueous solvents may also be present.Generally, the total amount of oxidizing agent in the oxidizing composition varies from about 1% to about 30%, for example, from about 1% to about 20%, from about 1% to about 15%, from about 1% to about 12%, from about 3% to about 20%, from about 3% to about 15%, from about 3% to about 12%, from about 5% to about 20%, from about 5% to about 15%, from about 5% to about 12%, from about 7% to about 20%, from about 7% to about 15%, from about 7% to about 12%. from approximately 9% to approximately 20%, from approximately 9% to approximately 15%, or from approximately 9% to approximately 12% by weight, relative to the total weight of the oxidizing composition. The pH of the oxidizing composition is typically less than 7, and can range from approximately 1 to approximately 6, such as from approximately 2 to approximately 5.

[0299] An exemplary oxidizing composition may be aqueous and comprise hydrogen peroxide as an oxidizing agent, wherein the hydrogen peroxide is present in the aqueous oxidizing composition in an amount ranging from about 5% to about 20%, for example, from about 7% to about 15%, from about 8% to about 13%, from about 8% to about 10%, from about 9% to about 13% or from about 10% to about 12%, for example, from about 7%, about 8%, about 9%, about 10%, about 11%, about 12%, about 13%, about 14% or about 15% by weight, relative to the total weight of the oxidizing composition. The oxidizing composition can therefore be, for example, a developer composition based on 10V, 20V, 30V or 40V hydrogen peroxide.

[0300] Typically, an oxidizing hair dye base or a hair lightening (bleach / highlight) composition is mixed with an oxidizing composition at or near the time of use. The mixing ratio may vary, for example, from about 1:5 to about 5:1, or from about 1:4 to about 4:1, from about 1:3 to about 3:1, or from about 1:2 to about 2:1, or may be about 5:1, about 4:1, about 3:1, about 2:1, about 1.5:1, about 1:1, about 1:1.5, about 1:2, about 1:3, about 1:4, or about 1:5 (dye base or lightening composition relative to the oxidizing composition). II. PROCESSES

[0301] The disclosure also relates to a process for treating keratin fibers, in particular human hair, in which a composition according to the disclosure is applied to the keratin fibers. The processes may be hair color modification processes, for example by dyeing or lightening the hair, and / or processes for reducing hair damage in hair color modification processes, providing hair strength in hair color modification processes, enabling hair fibers to maintain their integrity in hair color modification processes, and / or reducing hair elasticity in hair color modification processes.

[0302] In various embodiments, the processes include mixing a composition as disclosed with an oxidizing composition at or near the time of use in order to permanently dye hair. For example, the processes may include mixing of a composition as disclosed which comprises one or more oxidative dye compounds (e.g. one or more oxidation bases and one or more couplers) with an oxidizing composition such as an aqueous hydrogen peroxide-based developer composition at a mixing ratio of 3:1 to 1:3, such as 2:1 to 1:2, the application of the mixture to the hair, leaving the mixture on the hair for a desired processing time and then removing the mixture from the hair in order to dye the hair permanently.

[0303] In various embodiments, the processes include mixing a composition as disclosed with an oxidizing composition at or near the time of use for the purpose of lightening hair. For example, the processes may include mixing a composition as disclosed that contains one or more persalts (e.g., sodium persulfate, potassium persulfate, and / or ammonium persulfate) with an oxidizing composition such as an aqueous hydrogen peroxide-based developer composition at a mixing ratio of 3:1 to 1:3, such as 2:1 to 1:2, applying the mixture to the hair, leaving the mixture on the hair for a desired processing time, and then removing the mixture from the hair, wherein the process is a hair lightening (bleaching or highlighting) process.

[0304] The composition as disclosed can be used on wet or dry hair, and also on all hair types, including natural or dyed, permanently curled, bleached, or straightened hair. Given the beneficial effects obtained with the compositions as disclosed, it is possible to dye or lighten even hair that has been previously damaged by other chemical treatments.

[0305] The composition can be applied to the hair and left to act for a desired period of time, for example from about 10 minutes to about 2 hours, for example from about 15 minutes to about 1.5 hours, from about 20 minutes to about 60 minutes, or from about 30 minutes to about 45 minutes.

[0306] After applying the composition to the hair and leaving the composition to act on the hair, the composition can be removed, for example the hair can be washed with shampoo and / or rinsed with water.

[0307] In addition to excellent benefits in terms of hair colour and / or lightening, hair treated with compositions and processes as disclosed exhibits less damage than hair not treated with compositions and processes as disclosed. Treated hair may also exhibit lower elasticity and / or higher tensile strength than hair that is similarly dyed and / or lightened but not with compositions as disclosed.

[0308] 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 herein are provided only for this disclosure.

[0309] In this application, the use of the singular includes the plural unless specifically stated otherwise. The singular forms "a," "an," "the," "the," and "at least one" are understood to encompass both the plural and the singular, unless the context clearly indicates otherwise. The expression "one or more" means "at least one" and therefore includes individual components as well as mixtures / combinations. Similarly, the expression "one of their / her salts" also refers to "their / her salts."Thus, when the disclosure refers to "an element chosen 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.

[0310] The expression "and / or" should be understood as including both the conjunctive and the disjunctive. For example, "amino acids and / or their salts" means "amino acids and their salts" as well as "amino acids or their salts", and expressly covers either one or the other.

[0311] In this document, the term "salts" throughout the disclosure may include salts containing a counterion such as an alkali metal, an alkaline earth metal, or an 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.

[0312] As used herein, the expressions “and mixtures thereof”, “and mixtures of two or more of these”, “and one of their mixtures”, “and their combinations”, “and one of their combinations”, “and combinations of two or more of these”, “or their mixtures”, “or one of their mixtures”, “or their combinations”, “or combinations of two or more of these”, “or one of their combinations”, and similar expressions are used interchangeably to indicate that the list of components immediately preceding the expression, such as “A, B, C, D, or mixtures thereof”, means that the component(s) may be chosen from A, B, C, D, among A + B, among A + B + C, among A + D, among A + C + D, etc., without limitation on their variations. Thus, the components can be used individually or in any combination thereof.

[0313] Unless expressly stated otherwise, "approximately" means + / - 5%.

[0314] As used here, 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 will be present in the composition, namely, present in an amount greater than 0%.

[0315] All quantities indicated here are relative to the quantity of active material, unless otherwise stated.

[0316] All percentages, parts and ratios herein are based on the total weight of the compositions in this disclosure, unless otherwise stated.

[0317] In this application, the terms "keratin fibres" and "hair" are used interchangeably without being intended to be restrictive. A person skilled in the art will understand that keratin fibres include hair, such as hair growing from the scalp.

[0318] As used herein, the expression "apply a composition to the hair," and its variations, is intended to refer to bringing the hair into contact with at least one of the compositions in the disclosure, in any manner whatsoever. It may also refer to bringing the hair into contact with an effective quantity.

[0319] The expression "hair treatment" (and its grammatical variations) as used herein refers to the application of the compositions of this disclosure to the surface of the hair. The expression "hair treatment" (and its grammatical variations) as used herein also refers to bringing the hair into contact with the compositions of this disclosure.

[0320] 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. A composition "free" of a component is intended to contain none of the specified components. However, it is understood that the expressions "free" and "substantially free" refer 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.

[0321] The following examples are intended to illustrate embodiments of this disclosure but are not intended to be exhaustive. 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. Therefore, this disclosure is intended to cover modifications and variations that fall within the scope of the appended claims and their equivalents. EXAMPLES

[0322] 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. Example 1 - Compositions

[0323] Compositions 1A-1F according to the disclosure were prepared as indicated in Table 1.

[0324] [Tables 1] IA IB IC 1D 1E Glycine betaine 2.0 2.0 2.0 4.0 Glycine 2.0 Surfactants (oleic acid, coco glucoside, and / or cetearyl glucoside) 4.6 3.2 3.2 3.2 3.2 Ammonium hydroxide 4.5 4.5 4.5 4.5 Ethanolamine 12.2 1.6 1.6 1.6 0.6 Fatty compounds (shea butter, xanthan gum, cetearyl alcohol and / or oleyl alcohol) 19.2 23.2 23.2 23.2 23.2 Ascorbic acid 0.25 Tetrasodium glutamate and diacetate 0.24 0.24 0.24 0.24 0.24 Citric acid 2.0 2.0 Sodium metabisulfite 0.7 Solvents (water and non-aqueous solvents) Qs per 100 Qs per 100 Qs per 100 Qs per 100 Qs per 100

[0325] Compositions 1A-1E can be mixed with an oxidizing composition, for example a 20V, 30V, or 40V hydrogen peroxide-based developer, and applied to the hair for lightening purposes. The mixture can be left on the hair for a desired period and then rinsed out.

[0326] In addition, compositions 1A-1E may include one or more oxidative dye compounds and / or one or more direct dye compounds. By way of example, such variations on compositions 1A-1E may include 4-amino-2-hydroxytoluene, p-aminophenol, 1-hydroxyethyl 4,5-diaminopyrazole sulfate, toluene 2,5-diamine, 2-methyl-5-hydroxyethylaminophenol, or combinations of two or more of these. The composition may be mixed with an oxidizing composition, for example, a 20V, 30V, or 40V hydrogen peroxide-based developer, and applied to the hair to color the hair. The mixture may be left on the hair for a desired period and then removed by rinsing.

[0327] Example 2 - Evaluation of the benefits to hair

[0328] In order to evaluate the benefits of hair treatment with compositions according to the disclosure, comparative C1-C3 compositions indicated in Table 2 were prepared.

[0329] [Tables2] Cl C2 C3 Surfactants (oleic acid, coco glucoside, and / or cetearyl glucoside) 4.6 3.2 3.2 Ammonium hydroxide 4.5 4.6 Ethanolamine 12.2 1.6 0.6 Fatty compounds (shea butter, xanthan gum, cetearyl alcohol and / or oleyl alcohol) 19.2 23.2 23.2 Ascorbic acid 0.25 Tetrasodium glutamate and diacetate 0.24 0.24 0.24 Citric acid 1.0 Solvents (water and non-aqueous solvents) Qs per 100 Qs per 100 Qs per 100

[0330] In order to evaluate the benefits to hair from the use of compositions according to the disclosure, the following studies were carried out.

[0331] First, compositions IA and Cl were mixed separately with a commercially available aqueous hydrogen peroxide 20V developer composition at a mixing ratio of 1:1. Each mixture was applied to identical strands of natural hair, left to act at room temperature for 35 minutes, and the strands were then rinsed, shampooed with a commercially available shampoo, and dried.

[0332] Once the strands were dry, the hair was cut into microscopic pieces, and 50 µg of each strand was weighed and placed in the sample tray of a TA Discovery DSC 2500 instrument (crimped and sealed tray). After 24 hours in the tray, the instrument was equilibrated at 40 °C, and the sample was analyzed up to 180 °C at a ramp rate of 10 °C per minute. Finally, the denaturation temperature of each sample was measured ([Fig. 2]).

[0333] Fig. 2 shows that the denaturation temperature of the sample treated with composition IA was approximately one degree Celsius higher than that of the sample treated with composition Cl. This result, which was considered statistically significant, demonstrates that the hair treated with composition IA according to the disclosure exhibited surprisingly increased strength and integrity compared to the hair treated with the comparative composition.

[0334] The procedure was repeated using compositions 1B-1E and C2-C3. Figure 3 shows the DSC results obtained. As shown in Figure 3, the denaturation temperatures of the samples treated with compositions 1B-1E were more than one full degree Celsius higher than those of the sample treated with compositions C2 and C3, with compositions IB and C1C providing an increase of more than three degrees Celsius. These results are also considered statistically significant and confirm that hair treated with compositions according to disclosure has remarkably increased strength and integrity compared to hair treated with compositions not in accordance with disclosure.

[0335] Example 2 thus demonstrates that the hair color-modifying compositions according to the disclosure provide surprisingly increased fiber strength and integrity compared to traditional hair color-modifying compositions. Although it is known that hair color-modifying compositions generally damage the hair, the increased denaturation temperature observed in hair treated with compositions according to the disclosure confirms that the presence of osmolytes in the hair color-modifying compositions surprisingly and unexpectedly minimizes and / or prevents such damage, provides hair strength, and allows the fibers capillaries to maintain their integrity in the hair color modification processes. Example 3 - Comparative studies

[0336] The AF compositions in Table 3 can be prepared for further comparative studies.

[0337] [Tables3] ABCDEF Glycine betaine 2.00 2.00 2.00 Glycine betaine hydrochloride 2.00 2.00 2.00 Surfactants (oleic acid and / or coco glucoside) 4.57 4.57 4.57 4.57 4.57 4.57 Ammonium hydroxide 3.08 3.36 1.82 Ethanolamine 12.2 12.2 1.63 12.2 1.65 1.50 Fatty compounds (shea butter, xanthan gum, cetearyl alcohol and / or oleyl alcohol) 19.2 19.2 19.2 19.2 19.2 19.2 Ascorbic acid 0.25 0.25 0.25 0.25 0.25 0.25 Glutamate and tetrasodium diacetate 0.24 0.24 0.24 0.24 0.24 0.24 Lactic acid 1.80 1.80 Sodium metabisulfite 0.71 0.71 0.71 0.71 0.71 0.71 Solvents (water and non-aqueous solvents) Qs per 100 Qs per 100 Qs per 100 Qs per 100 Qs per 100 Qs per 100

[0338] The compositions in Table 3 can be used to study the impact that the quantities and types of osmolytes, alkaline agents and carboxylic acids have on the benefits conferred to the hair and / or the properties of the compositions.
