Description

Technical Field

[0001] The present invention relates to a composition for coloring or dyeing keratinous substances, preferably a cosmetic composition, comprising at least one oxidative coupler dye that produces at least one auto-coupling oxidative dye precursor by oxidation. The present invention also relates to a beauty method for coloring or dyeing keratinous substances using the same.

Background Art

[0002] It is known to dye keratin fibers, particularly human hair, with dyeing compositions containing oxidative coloring precursors and couplers generally called oxidative bases. These bases and these couplers are colorless or lightly colored compounds and can provide colored compounds through an oxidative condensation process in combination with an oxidizing agent product.

[0003] In addition to oxidative bases and couplers, oxidative catalysts that enhance oxidative coloring of hair are widely used. For example, WO2001 / 172272, EP0642783A, JP2014-114264A, JP2003-119115A, JP2003-055175A, EP1297817A, and EP1325733A disclose the use of oxidative catalysts such as metals alone or their salts, metals with ligands (acids, hexacyanoferrates), or chelating agents (EDTA), enzymes of the peroxidase family (lactoperoxidase, horseradish peroxidase), or laccase or tyrosinase, and halogen oxidative catalysts (iodine).

[0004] Most oxidative precursors or bases for hair coloring are evaluated within strict regulatory limits due to their high risks regarding human safety and environmental footprint. Furthermore, there are also concerns about the safety of some catalysts used to enhance oxidative coloring for humans and the environment. Therefore, there is a need to develop new methods for coloring or dyeing keratinous substances with less impact on human safety and the environment.

[0007] An object of the present invention is to provide a new composition for coloring or dyeing keratin substances without the need to use an oxidation precursor or a base.

Means for Solving the Problems

[0008] [[ID=Z23]]The above object of the present invention is (a) at least one oxidation coupler dye that generates at least one auto-coupling oxidation dye precursor by oxidation, and (b) at least one oxidation catalyst selected from (b1) an enzyme and (b2) an inorganic catalyst can be achieved by a composition comprising.

[0009] (a) The oxidation coupler dye may be selected from 1-naphthol and 6-hydroxyindole.

[0010] The composition according to the present invention may comprise at least one enzyme selected from (b1) peroxidase, particularly non-specific peroxidase.

[0011] The composition according to the present invention may comprise at least one inorganic catalyst selected from (b2) a metal catalyst.

[0012] The metal catalyst may be selected from a metal organic framework (MOF), a mesoporous structure in which a metal such as zeolite is doped inside, and a metal organic complex.

[0013] The metal in the metal catalyst is selected from copper, iron, titanium, magnesium, zinc, cobalt, platinum, cerium, nickel, silver, zirconium, chromium, molybdenum, tungsten, gold, vanadium, and combinations thereof, and is preferably selected from copper(II), iron(II) or (III), titanium(IV), magnesium(II), and combinations thereof, particularly copper(II).

[0014] Metal-organic frameworks (MOFs) or mesoporous structures doped with metal may have a mesoporous or microporous structure.

[0015] The mesoporous or microporous structure of a metal-organic framework (MOF) or a metal-doped mesoporous structure may have pore diameters in the range of 3 to 30 angstroms, preferably 5 to 25 angstroms, and more preferably 7 to 20 angstroms.

[0016] The metal-organic complex includes organic ligands that can be selected from porphyrin ligands, chlorin ligands, such as chlorophyllin, bacteriochlorin ligands, β-diketone ligands, and combinations thereof.

[0017] The metal-organic complex can be selected from metal acetylacetonates, metal chlorophyllins, and metal phthalocyanines.

[0018] The amount of (a) oxide coupler dye in the composition may be in the range of 0.05% to 3% by mass, preferably 0.075% to 1% by mass, and more preferably 0.1% to 0.5% by mass, relative to the total mass of the composition.

[0019] The amount of enzyme (b1) in the composition may be in the range of 0.005% to 0.3% by mass, preferably 0.01% to 0.2% by mass, and more preferably 0.015% to 0.1% by mass, relative to the total mass of the composition.

[0020] The amount of (b2) inorganic catalyst in the composition is in the range of 0.05% to 1% by mass, preferably 0.1% to 0.75% by mass, and more preferably 0.2% to 0.5% by mass, relative to the total mass of the composition.

[0022] The present invention also relates to a method for coloring or dyeing a keratin substance, preferably hair, (1) A step of mixing the first composition and the second composition to prepare a mixture, The first composition is (a) At least one oxidative coupler dye that generates at least one autocoupling oxidative dye precursor by oxidation, and (b) At least one oxidation catalyst selected from (b1) enzymes and (b2) inorganic catalysts Includes, The second composition comprises at least one oxidizing agent, and the process is as follows: (2) A step of applying the mixture to a keratin substance and This includes methods. [Modes for carrying out the invention]

[0023] As a result of diligent research, the inventors have discovered that a composition comprising at least one oxidation catalyst selected from (b)(b1) enzymes and (b2) inorganic catalysts can produce improved coloring properties even without using conventional oxidation dyes, by using a specific type of (a) at least one oxidation coupler dye as a starting material, thereby completing the present invention.

[0024] Therefore, the present invention is (a) At least one oxidative coupler dye that generates at least one autocoupling oxidative dye precursor by oxidation, (b) At least one oxidation catalyst selected from (b1) enzymes and (b2) inorganic catalysts This relates to a composition containing the following:

[0025] The compositions according to the present invention are highly preferable for coloring or dyeing keratinous substances, such as hair, because they can provide improved coloring properties without using traditional oxidative dyes, most of which are known to pose high risks to human safety and the environment.

[0026] The compositions and methods according to the present invention will be described in more detail below.

[0027] [Composition] The composition according to the present invention is (a) At least one oxidative coupler dye that generates at least one autocoupling oxidative dye precursor by oxidation, (b) At least one oxidation catalyst selected from (b1) enzymes and (b2) inorganic catalysts Includes.

[0028] The compositions according to the present invention are intended for use in coloring or dyeing keratinous substances. Therefore, the compositions according to the present invention may be topical cosmetic compositions intended for application on keratinous substances. For the purposes of the present invention, the term "keratinous substance" includes substances containing keratin as a main component, preferably hair.

[0029] The composition according to the present invention can color keratin fibers. In a preferred embodiment, the composition according to the present invention is for coloring or dyeing keratin, particularly hair. Therefore, the present invention may be a hair coloring composition.

[0030] In a preferred embodiment, the composition according to the present invention can be used for hair coloring. Therefore, the composition may be a hair coloring product.

[0031] The composition according to the present invention can produce an oxidation dye by a two-step reaction. First, (a) the oxidation coupler dye of the present invention is oxidized by the action of (b) an oxidation catalyst to produce an autocoupling oxidation dye precursor. Then, the produced autocoupling oxidation dye precursor self-couples to produce an oxidation dye. Therefore, the composition according to the present invention can produce an oxidation dye without using traditional oxidation precursors / bases that are unsafe for human health to color keratinous materials. Thus, the present invention can provide coloring or dyeing of keratinous materials with minimal impact on human safety and the environment.

[0032] The compositions according to the present invention can take various forms, such as solutions, gels, lotions, serums, suspensions, dispersions, fluids, milks, pastes, creams, foams, emulsions (O / W or W / O form), and multiple (e.g., W / O / W, polyol / O / W, and O / W / O) emulsions.

[0033] The components of the composition are described in detail below.

[0034] (Oxide coupler dye) The composition according to the present invention comprises (a) at least one oxide coupler dye. A single type of (a) oxide coupler dye may be used, or two or more different types of (a) oxide coupler dyes may be used in combination.

[0035] (a) The oxidative coupler dye of the present invention produces at least one autocoupling oxidative dye precursor by oxidation. For the purposes of the present invention, the term “autocoupling oxidative dye precursor” means a precursor that produces an oxidative dye by a self-coupling reaction. For the purposes of the present invention, the term “self-coupling” describes a molecule that can couple to itself in a standard oxidizing environment (oxygen in the air) to form new molecules, such as dimers, trimers, and polymers.

[0036] In particular, (a) the oxidation dye precursor is selected from 1-naphthol and 6-hydroxyindole. 1-naphthol and 6-hydroxyindole are 1,8-dihydroxynaphthalene and 5,6-dihydroxyindole, and it is known that these readily self-couple to form oxidation dyes of melanin derivatives of allomelanin and eumelanin, respectively. Allomelanin and eumelanin are known as colorants and can impart color to keratinic substances.

[0037] It is known that 1-naphthol and 6-hydroxyindole have lower human safety and environmental impact than most conventional oxidation precursors and couplers used for hair coloring, while it is also known that their coloring properties are limited or nonexistent.

[0038] Specifically, 1-naphthol and 6-hydroxyindole can be oxidized in situ by the action of the oxidation catalyst of the present invention (b), which will be described later, to form 1,8-dihydroxynaphthalene and 5,6-dihydroxyindole, respectively.

[0039] [ka]

[0040] Subsequently, the generated 1,8-dihydroxynaphthalene and 5,6-dihydroxyindole are spontaneously converted to allomelanin and eumelanin, respectively. The generated allomelanin and eumelanin can diffuse into the keratinous substance, preferably the interior of the hair, to color the keratinous substance. Thus, 1-naphthol and 6-hydroxyindole can be said to be autocoupling oxidative dye precursors, meaning that these compounds are starting materials for the autocoupling of oxidative dyes, resulting in an autocoloring system. 1,8-dihydroxynaphthalene and 5,6-dihydroxyindole autocouple under atmospheric oxygen, and indeed 1-naphthol and 6-hydroxyindole become autocoupling oxidative dye precursors. Because 1,8-dihydroxynaphthalene and 5,6-dihydroxyindole autocouple, the present invention has the advantage that it does not require, and is not essential, the use of coupling 1-naphthol or 6-hydroxyindole with traditional oxidative precursors / bases that are not safe with respect to human health.

[0041] The amount of (a) an oxide coupler dye, preferably 1-naphthol and / or 6-hydroxyindole, in the composition according to the present invention may be 0.05% by mass or more, preferably 0.075% by mass or more, and more preferably 0.1% by mass or more, based on the total mass of the composition.

[0042] The amount of (a) an oxide coupler dye, preferably 1-naphthol and / or 6-hydroxyindole, in the composition according to the present invention may be 3% by mass or less, preferably 1% by mass or less, and more preferably 0.5% by mass or less, based on the total mass of the composition.

[0043] The amount of (a) an oxide coupler dye, preferably 1-naphthol and / or 6-hydroxyindole, in the composition according to the present invention may be in the range of 0.05% to 3% by mass, preferably 0.075% to 1% by mass, and more preferably 0.1% to 0.5% by mass, based on the total mass of the composition.

[0044] In the context of this specification, any combination of the above upper and lower limits may represent a preferred range of quantities.

[0045] (Oxidation catalyst) The compositions according to the present invention include at least one oxidation catalyst selected from (b)(b1) enzymes and (b2) inorganic catalysts. A single type of (b) oxidation catalyst may be used, or two or more different types of (b) oxidation catalysts may be used in combination.

[0046] The (b) oxidation catalyst of the present invention is selected from (b1) an enzyme and (b2) an inorganic catalyst. Each of (b1) the enzyme and (b2) the inorganic catalyst can be used alone, or each of (b1) the enzyme and (b2) the inorganic catalyst can be used in combination.

[0047] As explained above, (b) the oxidation catalyst catalyzes the hydroxylation reaction of (a) 1-naphthol and / or 6-hydroxyindole to produce 1,8-dihydroxynaphthalene and / or 5,6-dihydroxyindole, respectively.

[0048] (b) Examples of substrates for the oxidation catalyst include oxidizing agents such as hydrogen peroxide and peroxide salts such as sodium peroxygenated, potassium peroxide, and calcium peroxide. Preferably, the substrate for the oxidation catalyst is hydrogen peroxide (H2O2).

[0049] (b1) Enzymes and (b2) Inorganic catalysts are described in detail below.

[0050] (b1) Enzyme A single type of (b1) enzyme may be used, or a combination of two or more different types of (b1) enzymes may be used.

[0051] (b1) The enzyme is a biocatalyst well known in the art, and therefore, it can be said that (b1) is a biocatalytic enzyme.

[0052] (b1) The enzyme is not limited as long as it can catalyze the hydroxylation reaction of (a) 1-naphthol and 6-hydroxyindole.

[0053] In a preferred embodiment of the present invention, (b1) the enzyme is selected from peroxygenases (EC1.1.1 and 1.1.2), particularly nonspecific peroxygenases (UPO, EC1.11.2.1). Nonspecific peroxygenases are used in the following reactions: RH + H2O2 ⇔ ROH + H2O (In the formula, R may represent a monovalent organic group, in particular a monovalent hydrocarbon group.) It catalyzes [the process]. Therefore, nonspecific peroxygenases use hydrogen peroxide as a substrate. Consequently, peroxygenases can be used in combination with hydrogen peroxide as an oxidizing agent.

[0054] The use of peroxygenase has the advantage that peroxygenase is more stable than conventional enzymes such as peroxidase, laccase, and tyrosinase, and maintains its activity under ambient conditions.

[0055] (b1) As for commercially available enzymes, one example is nonspecific peroxygenase under the name UPO (nonspecific peroxygenase) provided by Aminoverse.

[0056] If the composition according to the present invention contains (b) at least one (b1) enzyme as an oxidation catalyst, the amount of enzyme (b1) in the composition may be 0.005% by mass or more, preferably 0.01% by mass or more, and more preferably 0.015% by mass or more, based on the total mass of the composition.

[0057] If the composition according to the present invention contains (b) at least one (b1) enzyme as an oxidation catalyst, the amount of enzyme (b1) in the composition may be 0.3% by mass or less, preferably 0.2% by mass or less, and more preferably 0.1% by mass or less, based on the total mass of the composition.

[0058] If the composition according to the present invention contains (b) at least one (b1) enzyme as an oxidation catalyst, the amount of enzyme (b1) in the composition may be in the range of 0.005% to 0.3% by mass, preferably 0.01% to 0.2% by mass, and more preferably 0.015% to 0.1% by mass, relative to the total mass of the composition.

[0059] (b2) Inorganic catalyst A single type of (b2) inorganic catalyst may be used, or a combination of two or more different types of (b2) inorganic catalysts may be used.

[0060] (b2) The inorganic catalyst is not limited as long as it can catalyze the hydroxylation reaction of (a) 1-naphthol and 6-hydroxyindole.

[0061] (b2) The inorganic catalyst is preferably selected from metal catalysts.

[0062] (b2) The inorganic catalyst metal can be selected from, but is not limited to, copper, iron, titanium, magnesium, zinc, cobalt, platinum, cerium, nickel, silver, zirconium, chromium, molybdenum, tungsten, gold, vanadium, and combinations thereof. Preferably, (b2) the inorganic catalyst metal is selected from copper(II), iron(II) or (III), titanium(IV), magnesium(II), and combinations thereof, in particular copper(II).

[0063] The metal catalyst is preferably selected from metal-organic frameworks (MOFs), metal-doped mesoporous structures such as zeolites, metal-organic complexes, and combinations thereof.

[0064] Metal-organic structures (MOFs) may include metal ions and organic ligands having two or more sites capable of coordinating with the metal within the molecule. Examples of organic ligands in MOFs include, for example, dicarboxylic acids and their derivatives, tricarboxylic acids and their derivatives, tetracarboxylic acids and their derivatives, imidazoles and their derivatives, pyrazoles and their derivatives, triazoles and their derivatives, tetraazoles and their derivatives, pyridines and their derivatives, pyrimidines and their derivatives, triazines and their derivatives, and combinations thereof. As a preferred example, the organic ligand of a metal-organic structure (MOF) is selected from tricarboxylic acids and their derivatives.

[0065] A metal-doped mesoporous structure has a mesoporous structure made of an inorganic material. Preferably, a metal-doped mesoporous structure has a mesoporous structure made of a metal oxide. The metal oxide may be an aluminosilicate, preferably a crystalline aluminosilicate. In one preferred embodiment, the metal oxide may be an aluminosilicate material selected from zeolites and zeotype materials. The zeolite framework may be selected from MFI, BEA, MOR, AEL, CHA, ERI, TON, and FER, in particular from BEA and MFI.

[0066] (b2) Metal-organic frameworks (MOFs) as inorganic catalysts and metal-doped mesoporous structures may have a mesoporous or microporous structure. In this embodiment, the pore diameter of the mesoporous or microporous structure may be in the range of 3 to 30 angstroms, preferably 5 to 25 angstroms, and more preferably 7 to 20 angstroms. For the purposes of the present invention, the pore diameter here may mean the diameter of the most abundant pores in the microporous structure. The pore diameter can be measured by any means common in the art, for example, by a pore size distribution plot obtained from nitrogen adsorption-desorption isotherms and by a porosity analyzer.

[0067] (b2) As a commercially available metal-organic framework (MOF) for use as an inorganic catalyst, we can mention the metal-organic framework sold by BASF under the name Basolite F300, which has a tricarboxylic acid-iron network with a pore size of 12 angstroms to 20 angstroms.

[0068] Metal-organic frameworks (MOFs) and (b2) mesoporous structures doped with metal as an inorganic catalyst are typically solid under ambient conditions (25°C, 1 atm). In one embodiment of the present invention, the metal-organic frameworks (MOFs) and the mesoporous structures doped with metal are in the form of particles. In this embodiment, the average (primary) particle diameter may be in the range of 1 nm to 200 nm, preferably 5 nm to 150 nm, and more preferably 10 nm to 100 nm. As used herein, average (primary) particle size or average (primary) particle diameter is the arithmetic mean diameter. As used herein, the term "average primary particle size" may refer to the volume-average size mean diameter given by the statistical particle size distribution for half of the population, D 50 This is referred to as [a specific term]. For example, the volume-average particle size can be measured using a laser diffraction particle size distribution analyzer, such as the Mastersizer 2000 from Malvern Corp.

[0069] Metal-organic frameworks (MOFs) and metal-doped mesoporous structures may have a mesoporous or microporous structure. Metal-organic frameworks (MOFs) and metal-doped mesoporous structures may have a thickness of 25-500 m 2 / g, preferably 50-400m 2 / g, more preferably 70-300m 2The specific surface area (SW) per unit mass can be expressed in the range of / g. The specific surface area per unit mass can be determined by the nitrogen absorption method known as the BET (Brunauer-Emmett-Teller) method, which is described in The Journal of the American Chemical Society, Vol. 60, p. 309, February 1938, and corresponds to the international standard ISO 5794 / 1 (Addendum D). The BET specific surface area corresponds to the total specific surface area of ​​the particle under consideration.

[0070] (b2) Commercially available mesoporous structures doped with metal as inorganic catalysts include: - Zeolite beta-BEA with a pore diameter of 7 angstroms, doped with iron(II), iron(III), or copper(II), supplied by Clariant under the names FeCZB 30, FeCZB 25, and CuCZB 30, respectively, and - Zeolite pentasil MFI with a pore diameter of 5.6 angstroms, doped with iron(II), iron(III), copper(II), or titanium silicate, sold by Clariant under the names FeCZP 30, FeCZP 27, CuCZP 30, and [Ti]CZP, respectively. We can list some examples.

[0071] In a preferred embodiment of the present invention, (b2) the metal-doped mesoporous structure as an inorganic catalyst is selected from zeolite betacopper(II), zeolite pentasylcopper(II), zeolite betairon(II), zeolite betairon(III), zeolite betairon(II), and combinations thereof.

[0072] Metal-organic complexes may contain metal ions and organic ligands that coordinate to the metal ions. The organic ligands of metal-organic complexes can be selected from porphyrin ligands, chlorin ligands, such as chlorophyllin, bacteriochlorin ligands, β-diketone ligands, and combinations thereof. Examples of β-diketone ligands include, but are not limited to, acetylacetonate, dipivaloylmethane, and combinations thereof, with acetylacetonate being preferred. Metal-organic complexes differ from metal-organic structures (MOFs) in that they do not contain porous structures.

[0073] The metal-organic complex is preferably selected from metal acetylacetonates, metal chlorophyllins, and metal phthalocyanines.

[0074] (b2) As for commercially available metal-organic complexes as inorganic catalysts, - Products of metal acetylacetonates, for example, bis(2,4-pentanedione)copper(II) and tris(2,4-pentanedione)iron(III), - Products of metal chlorophyllin, such as sensitive nature col green and chlorophyllin copper complexes, and - Products containing metal phthalocyanines, e.g., copper phthalocyanine and pigment blue 15 We can list some examples.

[0076] Free metal ions leached from catalysts can be problematic for human health and the environment, but the use of the inorganic catalyst (b2) of the present invention has the advantage of not generating them. In particular, free metal ions can penetrate deep into keratinous materials, which can lead to the breakdown and destruction of protein structures. Since the size of the inorganic catalyst (b2) and enzyme (b1) of the present invention is not small enough to penetrate keratinous materials, these problems are not caused by the use of these oxidation catalysts.

[0077] If the composition according to the present invention contains (b) at least one (b2) inorganic catalyst as an oxidation catalyst, the amount of the (b2) inorganic catalyst in the composition may be 0.05% by mass or more, preferably 0.1% by mass or more, and more preferably 0.2% by mass or more, based on the total mass of the composition.

[0079] If the composition according to the present invention contains (b) at least one (b2) inorganic catalyst as an oxidation catalyst, the amount of the (b2) inorganic catalyst in the composition may be in the range of 0.05% to 1% by mass, preferably 0.1% to 0.75% by mass, and more preferably 0.2% to 0.5% by mass, based on the total mass of the composition.

[0080] (Optional components) - Oxidizing agent The compositions according to the present invention can be combined with at least one oxidizing agent immediately before use for coloring or dyeing keratinous substances.

[0081] One type of oxidizing agent may be used alone, or two or more types of oxidizing agents may be used in combination.

[0082] The oxidizing agent can be selected from hydrogen peroxide, peroxygenated salts, and compounds capable of producing hydrogen peroxide by hydrolysis, i.e., from hydrogen peroxide production systems. For example, the oxidizing agent can be selected from aqueous hydrogen peroxide solutions, urea peroxide, alkali metal bromates and ferricyanides, and perates of alkali metals or alkaline earth metals, such as perborates, persulfates, peracids and percarbonates. At least one oxidase enzyme selected from, for example, laccase, peroxidase and 2-electron oxidoreductase, such as uricase, can also be used as an oxidizing agent if appropriate in the presence of their respective donors or cofactors.

[0083] In one preferred embodiment of the present invention, the oxidizing agent is hydrogen peroxide, such as an aqueous solution of hydrogen peroxide.

[0084] If the composition according to the present invention contains at least one oxidizing agent, the amount of the oxidizing agent in the composition may be 0.5% by mass or more, preferably 0.75% by mass or more, and more preferably 1% by mass or more, based on the total mass of the composition.
