[0001] This invention relates to the field of hair treatment technology. More specifically, it relates to compositions for hair. Background Technology

[0005] Patent Document 1: International Publication No. 2024 / 122328. Summary of the Invention

[0006] The problem the invention aims to solve

[0007] Generally speaking, micron- and nano-sized bubbles with a diameter of less than 100 μm have a very slow or non-floating speed in liquids compared to larger bubbles, and thus the solubility of the gas forming the bubbles in the liquid is significantly improved. Furthermore, it is believed that more specific properties can be identified due to the type of liquid as the matrix, the gas forming the bubbles, and their interactions. For example, Patent Document 1 discloses a cosmetic composition containing microbubbles of an inert gas (but excluding carbon dioxide) (claims of Patent Document 1). According to this technology, a cosmetic composition that improves the stability of cosmetic ingredients containing easily oxidized and deteriorated components and has good usability can be provided (paragraph

[0007] of Patent Document 1).

[0008] As mentioned above, there is a need to discover the specific properties brought about by microbubbles and to effectively apply these properties to specific uses. The present invention has been made in view of the above circumstances, and its object is to provide hair-related compositions, such as hair dye compositions and bleaching / removing agent compositions, that can be effectively applied by containing microbubbles.

[0023] In addition, unless otherwise explicitly stated, "%" refers to "mass %", "parts" refers to "mass parts", and "X~Y" means "above X and below Y".

[0024] In addition, for some compounds, names are used according to the list of ingredient names issued by the Japan Cosmetic Industries Association, or according to INCI (International Nomenclature of Cosmetic Ingredient).

[0025] Furthermore, regarding the names of some compounds, for polyoxyalkylene chains, polyoxyethylene chains are sometimes abbreviated as "POE," and polyoxypropylene chains are abbreviated as "POP." Additionally, the numbers in parentheses following these abbreviations indicate the molar amounts added. Furthermore, (meth)acrylic acid represents acrylic acid or methacrylic acid.

[0026] [1] Hair-related compositions, such as hair dye compositions and bleaching / removing compositions.

[0027] The hair compositions of the present invention, such as hair dye compositions and bleaching compositions, are characterized in that they contain micron-sized bubbles and / or nano-sized bubbles.

[0028] That is, in this invention, the hair dye composition is characterized by containing micron-sized bubbles and / or nano-sized bubbles, typically containing dye, and may contain alkali and / or oxidizing agents as needed. Additionally, the bleaching agent composition is characterized by containing micron-sized bubbles and / or nano-sized bubbles, and may contain alkali and / or oxidizing agents. Furthermore, the dye removal agent composition is characterized by containing micron-sized bubbles and / or nano-sized bubbles, and may contain alkali and / or oxidizing agents.

[0029] Hereinafter, when referring to these hair dye compositions, bleaching compositions and desaturating compositions in general, they will also be referred to simply as "compositions for hair".

[0030] 1. Microbubbles and / or nanobubbles (referred to as micro / nanobubbles)

[0031] In this disclosure, "micro / nanobubbles" refers to bubbles with a particle size (equivalent diameter of a sphere) of less than 100 μm, including microbubbles with a particle size of 1 μm or more but less than 100 μm and nanobubbles with a particle size of less than 1 μm. Therefore, micro / nanobubbles include, for example, microbubbles with a particle size (volume equivalent diameter) of less than 100 μm as shown in ISO 20480-1:2017 and JIS B8741-1:2019 (including microbubbles with a particle size of less than 1 μm, i.e., ultrafine bubbles).

[0032] The presence or absence of micro / nanobubbles can be confirmed by the following method: A laser is irradiated onto the object being measured, and the presence or absence of an optical path is used to confirm the presence of micro / nanobubbles. Specifically, if the optical path can be visually identified, micro / nanobubbles are present. Conversely, if the optical path cannot be visually identified, micro / nanobubbles are not present.

[0033] Furthermore, the presence of micro / nanobubbles can be confirmed using digital microscopy. Specifically, it can be confirmed by observing whether bubbles with a diameter greater than 1 μm and less than 100 μm are present in an image magnified at 100x or higher. Furthermore, the presence of micro / nanobubbles can also be confirmed through a decompression test. Specifically, the volume difference between 5 mL of the test solution before decompression and the volume of the test solution when decompressed to -0.07 MPa relative to atmospheric pressure is measured. Then, this volume difference is compared with the volume difference measured in a blank sample (a standard solution without micro / nanobubbles). If the volume difference of the test solution is greater than that of the blank sample, the presence of micro / nanobubbles can be confirmed.

[0034] Furthermore, the particle size can be determined by measuring the size of the bubbles. Specifically, when particle size is measured using laser diffraction-scattering (using a laser diffraction-scattering particle size analyzer), if bubbles with an equivalent spherical diameter of less than 100 μm are observed, it indicates the presence of micro / nano bubbles. On the other hand, if no bubbles with an equivalent spherical diameter of less than 100 μm are observed, i.e., if only bubbles with an equivalent spherical diameter of 100 μm or more are observed, it indicates the absence of micro / nano bubbles.

[0035] Furthermore, when the hair composition being tested contains particulate matter other than air bubbles (powder particles, emulsion particles, etc.), and these particulate matter are measured together with the air bubbles, the test results of the hair composition containing air bubbles and other particulate matter are compared with the test results of a hair composition that does not contain air bubbles due to defoaming but contains other particulate matter. The test results of the latter, which do not contain these particulate matter, are equivalent to the test results for air bubbles. That is, for example, in the laser diffraction scattering method, if the presence of air bubbles with an equivalent spherical diameter of less than 100 μm is confirmed in the test results for air bubbles, it can be determined that micro / nano bubbles are present.

[0036] Concentration of micro / nano bubbles (the amount of micro / nano bubbles present in a specified volume [number / cm³]) 3 There is no limit, but it is usually 100 pieces / cm. 3 The above can be 1,000 pieces / cm 3 The above can also be 20,000 pieces / cm 3That's all. On the other hand, there is no upper limit, but it is usually 1,000,000 pieces / cm. 3 The following are the upper and lower limits. These upper and lower limits can be combinations of each other, and the numerical range determined by combining these upper and lower limits is also disclosed in this specification. That is, for example, it can be 100 to 1,000,000 pieces / cm. 3 It can be 1,000 to 1,000,000 pieces / cm 3 It can also be 10,000~1,000,000 pieces / cm 3 .

[0037] Furthermore, the concentration of micro / nanobubbles can be determined using a digital microscope. Specifically, it can be determined using the automatic measurement function of a digital microscope (e.g., KEYENCE VHX-7100). That is, the number of bubbles the size of the object being measured within the captured image (e.g., at 20x magnification) can be counted (bubbles are identified by brightness differences within the image), and the concentration is calculated based on the number of micro / nanobubbles contained within the measurement area.

[0038] The types of gases constituting micro- and nano-bubbles are not limited, and are typically components that are in a gaseous state at room temperature, such as oxygen, nitrogen, carbon dioxide, argon, and gases formed by mixing two or more of the above-mentioned gases (e.g., air). Only one of these gases may be used, or two or more may be used in combination. From the viewpoint of easily obtaining the effects of the present invention, gases containing nitrogen or gases substantially composed of nitrogen are preferred.

[0039] Furthermore, the types of gases that constitute micro- and nanobubbles can be identified using gas chromatography-mass spectrometry (GC-MS).

[0040] In hair-making compositions containing micro- and nano-bubbles, application is more effective compared to hair-making compositions without micro- and nano-bubbles. More specifically, (1) a significant improvement in component permeability and / or (2) a significant improvement in coatability can be obtained.

[0041] The significantly improved permeability of the above-mentioned (1) component can be effectively applied in hair-applied compositions, especially in hair-applied compositions containing hair-penetrating components. That is, by utilizing this hair-applied composition, the hair-penetrating components can be effectively penetrated into the hair. The reason for the improved permeability through micro-nano bubbles is not yet clear, but it can be assumed that by containing micro-nano bubbles in the hair-applied composition, the proportion of the medium phase (aqueous phase, oil phase, etc.) that forms the bubbles is reduced, the hair-penetrating components are concentrated, and thus these components can easily move towards the hair side.

[0042] The significantly improved coatability described in (2) above can be effectively applied to hair compositions, especially those containing oily components. That is, hair compositions containing oily components generally tend to have poor spreadability compared to those without oily components; in contrast, hair compositions containing micro / nanobubbles exhibit excellent spreadability. While the reason for the improved coatability through micro / nanobubbles is not yet clear, it can be assumed that by containing nanobubbles in the hair composition, the bubbles are located at the interface between the hair composition and the hair when the composition is applied to the hair, thus facilitating spreadability.

[0043] Furthermore, the significant improvement in the permeability of component (1) and the significant improvement in the coatability of component (2) mentioned above can be achieved separately or simultaneously. That is, in a hair composition containing micro-nano bubbles, a hair composition containing both hair-penetrating components and oily components can achieve the two effects mentioned above (1) and (2).

[0044] Micro- and nano-bubbles can be arbitrarily contained in hair-making compositions. For example, methods such as: (1) rotating a liquid containing bubbles to further refine and break them; (2) passing a liquid containing bubbles through an action flow path (Venturi tube, static mixer, porous flow path, etc.) to further refine and break them; (3) pressurizing a gas to dissolve it supersaturated in a liquid; (4) heating and / or depressurizing a liquid containing dissolved gas (e.g., a saturated solution) to precipitate micro- and nano-bubbles; and (5) generating micro- and nano-bubbles from a liquid containing dissolved gas (e.g., a saturated solution) through cavitation. Only one of these methods may be used, or two or more may be used in combination. Among these, methods (1), (2), and (3) above are preferred.

[0045] 2. Hair penetration ingredients

[0046] Hair-penetrating ingredients are those components that penetrate into the hair when applied to a hair-care composition. Furthermore, they are components that exert their effects more significantly through penetration into the hair. More specifically, hair-penetrating ingredients can include dyes, alkalis, oxidizing agents, etc., and can also include moisturizing ingredients, touch-enhancing ingredients, etc. One or more of these can be used.

[0047] When hair-penetrating ingredients are included, their content ratio is not limited, but when the total hair-applied composition is set to 100% by mass, the content ratio of the hair-penetrating ingredients can be set to 0.001% by mass or more. This allows for an improved effect of the hair-penetrating ingredients with enhanced permeability. This lower limit can be further set to 0.01% by mass or more, 0.1% by mass or more, or 0.5% by mass or more. On the other hand, this upper limit can be, for example, set to 30% by mass or less, 25% by mass or less, 20% by mass or less, or 15% by mass or less. These upper and lower limits can be arbitrarily combined. For example, it can be 0.001 to 30% by mass, 0.01 to 25% by mass, 0.1 to 20% by mass, or 0.5 to 15% by mass. Furthermore, the above-mentioned mass percentages refer to the content used in the application.

[0048] Among the hair-penetrating components mentioned above, dyes are the ingredients that contribute to hair coloring. Specifically, these include oxidative dyes and direct dyes. One type can be used, or two or more can be used in combination.

[0049] Oxidative dyes consist of at least one of a dye intermediate and a coupling agent. The dye intermediate is the component that develops color through oxidative polymerization in the presence of an oxidizing agent. On the other hand, the coupling agent is the component that develops color through oxidative polymerization together with the dye intermediate in the presence of an oxidizing agent, thus enabling the production of colors that cannot be obtained from the oxidative polymer of the dye intermediate alone.

[0050] Examples of dye intermediates include p-phenylenediamine, toluene-2,5-diamine (p-toluenediamine), 2,2'-[(4-aminophenyl)imino]diethanol, N-phenyl-p-phenylenediamine, 4,4'-diaminodiphenylamine, 2-hydroxyethyl-p-phenylenediamine, 1-hydroxyethyl-4,5-diaminopyrazole, N,N-bis(2-hydroxyethyl)-p-phenylenediamine, o-chloro-p-phenylenediamine, 4-amino-m-cresol, 2-amino-4-hydroxyethylaminoanisole, 2,4-diaminophenol, 1,2,4-trihydroxybenzene, o-aminophenol, p-aminophenol, p-methylaminophenol, and melanin precursor compounds (indole compounds such as 5,6-dihydroxyindole and its derivatives, and indoline compounds such as 5,6-dihydroxyindole and its derivatives). Furthermore, dye intermediates may contain salts of the aforementioned compounds. Salts include acid addition salts. Examples of acid addition salts include addition salts of inorganic acids such as hydrochlorides and sulfates, and addition salts of organic acids such as acetates. These dye intermediates and their salts can be used individually or in combination with two or more.

[0051] Examples of coupling agents include 2,4-diaminophenoxyethanol, α-naphthol, 2,6-diaminopyridine, 5-amino-o-cresol, 5-(2-hydroxyethylamino)-2-methylphenol, resorcinol, 2-methylresorcinol, 4-chlororesorcinol, catechol, pyrogallol, gallic acid, hydroquinone, m-phenylenediamine, toluene-3,4-diamine, diphenylamine, 3,3'-iminobiphenyl, 1,5-dihydroxynaphthalene, tannic acid, o-aminophenol, m-aminophenol, p-aminophenol, and p-methylaminophenol. Furthermore, coupling agents may include salts of the aforementioned compounds. Salts include acid addition salts. Examples of acid addition salts include addition salts of inorganic acids such as hydrochlorides and sulfates, and addition salts of organic acids such as acetates. These coupling agents and their salts may be used individually or in combination with two or more.

[0052] Furthermore, of the above, o-aminophenol, p-aminophenol, and p-methylaminophenol can be used as both dye intermediates and coupling agents. For example, when these compounds are used as dye intermediates, they can be combined with other compounds exemplified as coupling agents. Similarly, when these compounds are used as coupling agents, they can be combined with other compounds exemplified as dye intermediates.

[0057] Examples of HC dyes include HC red, HC orange, HC yellow, HC blue, and HC violet. Only one of these can be used, or two or more can be used together.

[0060] In addition, examples include nitro dyes such as 4-nitro-o-phenylenediamine, 2-nitro-p-phenylenediamine, 2-amino-4-nitrophenol, 2-amino-5-nitrophenol, picric acid, picric acid and their salts, as well as carotenoid pigments, anthraquinone pigments, flavonoid pigments (anthocyanin pigments, chalcone pigments, flavonoid pigments), porphyrin dyes, diketone pigments, beet anthocyanin pigments, and azoketone pigments. Specifically, examples of natural dyes include madder pigment, extracted carotene, carmine pigment, cordyceps pigment, red cabbage pigment, perilla pigment, purple pyramidal pigment, blueberry pigment, blueberry pigment, grape peel pigment, grape juice pigment, purple sweet potato pigment, safflower yellow pigment, safflower red pigment, sorghum pigment, onion pigment, cocoa pigment, betel nut wood pigment, spirulina blue pigment, chlorophyll, beet red, red yeast rice pigment, indigo, gardenia pigment, curcumin, carmine pigment, sodium copper chlorophyllin, red pepper pigment, cordyceps pigment, and henna pigment. One of these can be used alone, or two or more can be used in combination.

[0061] Hair-use compositions that use dyes as hair-penetrating components include, for example, oxidative hair dyes (single-agent oxidative hair dyes, first agents of multi-agent oxidative hair dyes, etc.) that use oxidative dyes as hair-penetrating components, and hair coloring and conditioning agents that use alkaline dyes as hair-penetrating components.

[0062] Among the various dyes mentioned above, when comparing oxidative dyes with direct dyes, oxidative dyes generally achieve a greater effect in improving penetration. Furthermore, it is believed that micro-nano bubbles promote oxidation when oxidative dyes or their action occur. Therefore, when a hair composition containing oxidative dyes as hair-penetrating components contains micro-nano bubbles, a superior hair-dyeing effect can be obtained compared to compositions without micro-nano bubbles. Moreover, among the direct dyes mentioned above, when comparing ionic and nonionic direct dyes, nonionic direct dyes tend to achieve a more significant effect in improving penetration. Furthermore, among nonionic direct dyes, HC dyes are more likely to achieve a greater effect in improving penetration compared to other nonionic direct dyes.

[0063] When this hair-applied composition contains a dye as a hair-penetrating component, its content ratio is not limited, but when the total hair-applied composition is set to 100% by mass, its lower limit can be set to 0.01% by mass or more. This allows for effective hair dyeing and easy acquisition of excellent color tones. It can be further set to 0.05% by mass or more, or even 0.1% by mass or more. On the other hand, its upper limit can be set to 5% by mass or less. This easily improves solubility. This upper limit can be further set to 3% by mass or less, or even 2% by mass or less. These upper and lower limits can be combined arbitrarily. For example, it can be 0.01 to 5% by mass, or further set to 0.05 to 3% by mass, or even further set to 0.1 to 2% by mass. Furthermore, the above-mentioned mass percentages refer to the content used in the application.

[0064] Among the aforementioned hair-penetrating ingredients, the alkali agent is a component that promotes hair swelling or enhances this effect; it is typically alkaline in its water-soluble state. Furthermore, when coexisting with an oxidizing agent, the alkali agent can decompose pigments such as melanin within the hair, thus enabling it to decolorize both black (undyed) and dyed hair. During the decolorization process, it can make the color caused by the dye more pronounced.

[0065] Organic bases, inorganic bases, and their salts can be cited as examples of alkaline agents.

[0066] Examples of organic bases include organic amines, basic amino acids (arginine, lysine and their salts, etc.), and guanidines and their salts (guanidine carbonate, etc.). Specifically, examples include monoethanolamine, diethanolamine, triethanolamine, monoisopropanolamine, aminomethylpropanol (2-amino-2-methyl-1-propanol, etc.), aminomethylpropanediol (2-amino-2-methyl-1,3-propanediol, etc.), and alkylamines such as monoethylamine and isopropylamine. Only one of these organic bases may be used, or two or more may be used in combination.

[0067] Inorganic bases can include hydroxides, chlorides, silicates, carbonates, bicarbonates, metasilicates, phosphates, sulfates, and ammonia. Specifically, examples include alkali metal hydroxides such as sodium hydroxide, alkali metal carbonates such as sodium carbonate, alkali metal bicarbonates such as sodium bicarbonate, alkaline earth metal hydroxides such as magnesium hydroxide and calcium hydroxide, alkaline earth metal carbonates such as magnesium carbonate and calcium carbonate, and ammonium salts such as ammonium carbonate and ammonium bicarbonate. Only one of these inorganic bases can be used, or two or more can be used in combination.

[0068] When this hair-applied composition contains an alkaline agent as a hair-penetrating component, its content is not limited. However, when the entire hair-applied composition is set to 100% by mass, its lower limit can be set to 0.1% by mass or more. It can be further set to 0.5% by mass or more, and further set to 1% by mass or more. On the other hand, its upper limit can be set to 15% by mass or less, and further set to 13% by mass or less, and further set to 10% by mass or less. These upper and lower limits can be combined arbitrarily. For example, it can be set to 0.5 to 8% by mass, further set to 1 to 6% by mass, and further set to 3 to 5% by mass. Thus, hair swelling effect, hair swelling promoting effect, decolorization effect, etc., can be effectively obtained. In addition, the above-mentioned mass percentage content is the content at the time of use.

[0069] Furthermore, when this hair-applied composition contains an alkaline agent as a hair-penetrating component, the pH of the hair-applied composition is not limited. Its lower limit can be configured with a pH exceeding 7, for example, a pH of 8 or higher, and further, a pH of 9 or higher. This allows for the effective attainment of hair swelling effects, hair swelling promotion effects, and decolorization effects. On the other hand, its upper limit can be set, for example, to a pH of 13.5 or lower, further to a pH of 13 or lower, and further to a pH of 12 or lower. These upper and lower limits can be arbitrarily combined. For example, the pH of the hair-applied composition can be set to exceed 7 and be below 13.5, further to 8 to 13, and further to 9 to 12.

[0070] Furthermore, the pH of the hair-applied composition is the pH at 25°C. This pH is typically measured using a 10% by mass dilution of the stock solution, but in cases of specific usage conditions, it is defined as the pH under those conditions. For example, when used after dilution with a specified amount of water, it refers to the pH at the diluted state after dilution with that specified amount of water. Additionally, when the hair-applied composition is mixed with other compositions (e.g., another agent in a multi-component hair dye composition), the pH is defined as the pH of the mixed composition.

[0071] Examples of hair-penetrating compositions that use alkali as a hair-penetrating agent include oxidative hair dyes (single-agent oxidative hair dyes, the first agent of two-agent oxidative hair dyes, etc.) that use alkali as a hair-penetrating agent, and bleaching agents that use alkali as a hair-penetrating agent.

[0072] Among the aforementioned hair-penetrating components, the oxidizing agent is the component that exerts an oxidizing effect. Furthermore, the oxidizing agent is a component that can cause the oxidizing dye to oxidize and polymerize when coexisting with oxidizing dyes. Moreover, when coexisting with an alkali agent, the oxidizing agent can decompose pigments such as melanin in the hair, thus making it a component capable of decolorizing black hair (undyed hair, etc.) and dyed hair. During decolorization, it can make the color caused by the dye clearer.

[0073] When this hair-applied composition contains an oxidizing agent as a hair-penetrating component, its content is not limited. However, when the total hair-applied composition is set to 100% by mass, its lower limit can be set to 0.1% by mass or more. It can be further set to 0.5% by mass or more, and further set to 1% by mass or more. On the other hand, its upper limit can be set to 20% by mass or less, and further set to 10% by mass or less, and further set to 7% by mass or less. These upper and lower limits can be combined arbitrarily. For example, it can be set to 0.1 to 20% by mass, further set to 0.5 to 10% by mass, and further set to 1 to 7% by mass. Thus, oxidative polymerization, decolorization, etc., can be effectively obtained. Furthermore, the above-mentioned mass percentages are the content at the time of use.

[0074] There is no limitation on the type of oxidizing agent; peroxide oxidizing agents can be cited as examples. Peroxide oxidizing agents are compounds with the structure shown as "-OO-". This structure is most commonly found in inorganic compounds as the peroxide ion (O2). 2- It exists in the form of peroxide structures (-OO-), percarboxylic acid structures (-CO-OO-), etc. in organic compounds. Only one of these can be used, or two or more can be used together.

[0075] Among the inorganic compounds mentioned above that are peroxide-type oxidants, examples include peroxides such as hydrogen peroxide (such as urea peroxide, melamine peroxide, hydrogen peroxide adducts of phosphates, and hydrogen peroxide adducts of pyrophosphates); peroxide salts (alkali metal salts such as potassium and sodium salts, magnesium salts, calcium salts, strontium salts, barium salts, and ammonium salts); persulfates (alkali metal salts such as potassium and sodium salts, and ammonium salts); percarbonates (alkali metal salts such as potassium and sodium salts, and ammonium salts); perborates (alkali metal salts such as potassium and sodium salts, and ammonium salts); and permanganates (alkali metal salts such as potassium and sodium salts, magnesium salts, calcium salts, strontium salts, barium salts, and ammonium salts). Only one of these can be used, or two or more can be used in combination.

[0076] In addition, examples of organic compounds that can be used as peroxide-based oxidants include percarboxylic acids such as performic acid, peracetic acid, and perbenzoic acid, as well as their salts. Examples of salts of percarboxylic acids include alkali metal salts such as potassium and sodium salts. Only one of these can be used, or two or more can be used in combination.

[0077] Furthermore, examples of non-peroxide oxidants (i.e., compounds that do not contain the structure shown by "-OO-") include bromates (alkali metal salts such as potassium and sodium salts). Only one of these can be used, or two or more can be used in combination.

[0078] Furthermore, when using hydrogen peroxide, the aforementioned oxidant may include a hydrogen peroxide stabilizer (a stabilizer for hydrogen peroxide). This stabilizer improves the stability of hydrogen peroxide. Examples of stabilizers for hydrogen peroxide include ethylene glycol phenyl ether (phenoxyethanol), hydroxyethane diphosphonates (tetrasodium hydroxyethane diphosphonate, disodium hydroxyethane diphosphonate, etc.), and stannates (sodium stannate, potassium stannate, etc.). Only one of these may be used, or two or more may be used in combination.

[0079] Hair-use compositions that use oxidants as hair-penetrating components include, for example, oxidative hair dyes (oxidative hair dyes, the second agent of compound oxidative hair dyes, etc.) and bleaching agents.

[0080] Moisturizing ingredients are those that impart moisture to hair upon penetration. Imparting moisture to hair means that the hair is healthier and softer compared to before. Specifically, key elements include: making hair softer; giving hair a more moisturized texture; further inhibiting dryness and brittleness; further reducing the feeling of damage; improving hair shine; and making hair less prone to tangling. Only one of these elements may be used, or two or more may be used in combination. Furthermore, moisturizing ingredients may be common to ingredients that function as touch-enhancing ingredients (described later). That is, the specified ingredient may function as either a moisturizing ingredient or a touch-enhancing ingredient.

[0081] When this hair-care composition contains moisturizing ingredients, the total percentage of these ingredients is not limited. However, if the total hair-care composition is 100% by mass, the lower limit can be set to 0.01% by mass or more. It can be further set to 0.05% by mass or more, or even 0.1% by mass or more. On the other hand, the upper limit can be set to 20% by mass or less, or even 10% by mass or less, or even 5% by mass or less. These upper and lower limits can be combined arbitrarily. For example, it can be 0.01 to 20% by mass, or even 0.05 to 10% by mass, or even 0.1 to 5% by mass. This allows for more effective penetration of the moisturizing ingredients containing micro-nano bubbles, and more significantly improves hair moisturizing. Furthermore, the above-mentioned percentages by mass refer to the content at the time of use.

[0082] In other words, moisturizing ingredients can include polyols, acidic mucopolysaccharides, ceramides, peptides and proteins, sugars, vitamins and their derivatives, plant extracts, and plant oils. Only one of these can be used, or two or more can be used in combination.

[0083] In the above examples, the valence and number of carbon atoms of the polyols are not limited, but the valence is preferably 2 to 5, and the number of carbon atoms is preferably 2 to 5. Specifically, examples include alkyl diols such as ethylene glycol, propylene glycol, butanediol, and pentanediol; oxodiethanol and oxodipropanol; ethylene glycol; propane-1,2-diol and trimethylene glycol; 1,2-butanediol, 1,3-butanediol, and 1,4-butanediol; isopentanediol, 1,5-pentanediol, and 1,2-pentanediol; glycerol, glycerol (1,2,3-butanetriol, 1,2,4-butanetriol, etc.), pentanetriol (1,2,3-pentanetriol, 1,2,5-pentanetriol, 2,3,4-pentanetriol, etc.), polyethylene glycol (excluding high-polymer polyethylene glycol), and 1,3-butanediol. These can be used alone or in combination with two or more. Among them, glycerol, polyethylene glycol, and 1,3-butanediol are preferred.

[0084] When this hair-care composition contains polyols as a moisturizing ingredient, the proportion of polyols is not limited. However, when the entire hair-care composition is set at 100% by mass, the lower limit can be set to 0.01% by mass or more. It can be further set to 0.05% by mass or more, and further to 0.1% by mass or more. On the other hand, the upper limit can be set to 30% by mass or less, and further to 20% by mass or less, and further to 10% by mass or less. These upper and lower limits can be combined arbitrarily. For example, it can be set to 0.01 to 30% by mass, further to 0.05 to 20% by mass, and further to 0.1 to 10% by mass. Thus, the effect of moisturizing hair can be effectively obtained. In addition, the above-mentioned mass percentages are the content at the time of use.

[0085] The acidic mucopolysaccharides mentioned above include compounds in which the constituent sugars of polysaccharides with hexosamine as the constituent sugar are acidic groups, with glycosaminoglycans being preferred.

Examples of salts include alkali metal salts (Li, Na, K, etc.), alkaline earth metal salts (Mg, Ca, etc.), ammonium salts, alcoholamine salts, and basic amino acid salts. Only one of these may be used, or two or more may be used in combination.

[0086] When this hair-care composition contains acidic mucopolysaccharide as a moisturizing ingredient, its content is not limited, but when the total hair-care composition is set at 100% by mass, its lower limit can be set to 0.001% by mass or more. It can be further set to 0.01% by mass or more, and it can be further set to 0.1% by mass or more. On the other hand, its upper limit can be set to 20% by mass or less, and it can be further set to 10% by mass or less, and it can be further set to 5% by mass or less. These upper and lower limits can be combined arbitrarily. For example, it can be 0.001 to 20% by mass, and it can be further set to 0.01 to 10% by mass, and it can be further set to 0.1 to 5% by mass. Thus, the effect of moisturizing hair can be effectively obtained. In addition, the above-mentioned mass percentage content is the content at the time of use.

It can be further set to 0.05% by mass or more, or even 0.1% by mass or more. On the other hand, its upper limit can be set to 20% by mass or less, or even 10% by mass or less, or even 5% by mass or less. These upper and lower limits can be combined arbitrarily. For example, it can be 0.01 to 20% by mass, or even 0.05 to 10% by mass, or even 0.1 to 5% by mass. Thus, the effect of moisturizing hair can be effectively obtained. Furthermore, the above-mentioned mass percentages refer to the content at the time of use.

[0092] In the above, peptides and proteins are compounds formed by peptide bonds of amino acids. The source of peptides is not limited and can be obtained by hydrolyzing proteins. That is, they can be obtained as protein hydrolysates or a portion thereof. Protein hydrolysates (also called "hydrolyzed proteins") are produced by hydrolyzing proteins and therefore usually exist as a mixture of various peptides and proteins. Protein hydrolysates can be used as a mixture without separating the necessary peptides, or the necessary peptides can be separated (i.e., purified) from the protein hydrolysates for use. In other words, only one peptide or protein can be used, or two or more can be used together.

[0093] Furthermore, the amino acid residues constituting the peptide are not limited, including α-amino acid residues, β-amino acid residues, γ-amino acid residues, and δ-amino acid residues.

[0115] When this hair-care composition contains vitamins and their derivatives as moisturizing ingredients, the proportion of these ingredients is not limited. However, when the entire hair-care composition is set at 100% by mass, the lower limit can be set to 0.01% by mass or more. It can be further set to 0.05% by mass or more, or even 0.1% by mass or more. On the other hand, the upper limit can be set to 20% by mass or less, or even 10% by mass or less, or even 5% by mass or less. These upper and lower limits can be combined arbitrarily. For example, it can be 0.01 to 20% by mass, or even 0.05 to 10% by mass, or even 0.1 to 5% by mass. Thus, the effect of moisturizing hair can be effectively obtained. In addition, the above-mentioned mass percentages are the content at the time of use.

[0117] When this hair-care composition contains plant extracts as moisturizing ingredients, the proportion of these extracts is not limited. However, when the total weight of the hair-care composition is 100% by mass, the lower limit can be set to 0.01% by mass or more. It can be further set to 0.05% by mass or more, or even 0.1% by mass or more. On the other hand, the upper limit can be set to 50% by mass or less, or even 30% by mass or less, or even 10% by mass or less. These upper and lower limits can be combined arbitrarily. For example, it can be 0.01 to 50% by mass, or even 0.05 to 30% by mass, or even 0.1 to 10% by mass. This effectively achieves the effect of moisturizing hair.

[0119] When this hair-care composition contains plant-based oil as a moisturizing ingredient, its content is not limited, but when the total weight of the hair-care composition is 100% by mass, the lower limit can be 0.01% by mass or more. It can be further set to 0.05% by mass or more, and further to 0.1% by mass or more. On the other hand, its upper limit can be set to 50% by mass or less, and further to 30% by mass or less, and further to 10% by mass or less. These upper and lower limits can be combined arbitrarily. For example, it can be 0.01 to 50% by mass, and further to 0.05 to 30% by mass, and further to 0.1 to 10% by mass. Thus, the effect of moisturizing hair can be effectively obtained. Furthermore, the above-mentioned mass percentages refer to the content at the time of use.

[0120] Touch-enhancing ingredients are those that improve the feel of hair upon penetration. Improved hair feel means that the hair surface is smoother compared to before. Specifically, factors include better finger slippage (smoother finger movement), softer hair, and less tangling. One or more of these can be used. Furthermore, touch-enhancing ingredients can be common to the aforementioned moisturizing ingredients. That is, the specified ingredient may function as both a touch-enhancing ingredient and a moisturizing ingredient.

[0121] When this hair-care composition contains a touch-enhancing ingredient, its total content is not limited, but when the total hair-care composition is 100% by mass, its lower limit can be set to 0.01% by mass or more. It can be further set to 0.05% by mass or more, and further set to 0.1% by mass or more. On the other hand, its upper limit can be set to 30% by mass or less, and further set to 20% by mass or less, and further set to 10% by mass or less. These upper and lower limits can be combined arbitrarily. For example, it can be set to 0.01 to 30% by mass, and further set to 0.05 to 20% by mass, and further set to 0.1 to 10% by mass. As a result, the penetration of the touch-enhancing ingredient associated with micro-nano bubbles can be obtained more effectively, and the effect of improving the touch of hair can be obtained more significantly. In addition, the above-mentioned mass percentage content is the content at the time of use.

[0122] Examples of ingredients that enhance tactile sensation include amino acids (amino acids, amino acid derivatives, and their salts) and amino acid-like components, peptides, silicones, and hematin. One of these can be used alone, or two or more can be used in combination.

[0123] Among the above, examples of amino acids (amino acids, amino acid derivatives, and their salts) and amino acid-like components include taurine, glycine, betaine, alanine, leucine, serine, threonine, cysteine, cystine, methionine, ornithine, lysine, arginine, aspartic acid, asparagine, glutamic acid, glutamine, tyrosine, phenylglycine, tryptophan, theanine, and threonine. Only one of these can be used, or two or more can be used in combination. These amino acids can be derived from natural or non-natural sources, and, in the case of optically active forms, can be either L-forms or D-forms.

[0124] When this hair-care composition contains amino acids as a touch-enhancing ingredient, the proportion of amino acids is not limited. However, when the total weight of the hair-care composition is 100% by mass, the lower limit can be 0.01% by mass or more. It can be further set to 0.05% by mass or more, or even 0.1% by mass or more. On the other hand, the upper limit can be set to 30% by mass or less, or even 20% by mass or less, or even 10% by mass or less. These upper and lower limits can be combined arbitrarily. For example, it can be set to 0.01 to 30% by mass, or even 0.05 to 20% by mass, or even 0.1 to 10% by mass. This effectively achieves a touch-enhancing effect. Furthermore, the above-mentioned mass percentages refer to the content used in the application.

[0125] In the above, a peptide is a compound having a structure in which multiple amino acids are linked together by peptide bonds, as described in the moisturizing ingredients. Moreover, among various peptides, at least one of hydrolyzed collagen, hydrolyzed silk, hydrolyzed keratin, and hydrolyzed casein is preferred. Furthermore, from the viewpoint of improving the feel of hair, at least one of hydrolyzed collagen, hydrolyzed silk, and hydrolyzed keratin is preferred, and it is particularly preferred that at least hydrolyzed collagen is included.

[0126] When peptides are used as a touch-enhancing ingredient, a particularly superior touch-enhancing effect can be achieved. This is believed to be due to the presence of micro-nano bubbles, which allows peptides to easily penetrate the hair. Good peptide penetration can improve the shape dispersion of each hair, enhancing hair neatness. Furthermore, good peptide penetration can improve damage to the hair cuticle, thus improving hair combability.

[0127] The molecular weight of the peptide is not limited, but from the perspective of hair penetration, peptides with a mass-average molecular weight of 10,000 or less are preferred. The upper limit of the mass-average molecular weight of the peptide can be further set to 5,000 or less, further set to 3,000 or less, and further set to 1,000 or less. On the other hand, the lower limit of the mass-average molecular weight of the peptide is not limited, but from the viewpoint of improved feel and persistence, it can be 100 or more, further set to 200 or more, further set to 250 or more, and further set to 300 or more. The above upper and lower limits can be combined arbitrarily. Therefore, the mass-average molecular weight of the peptide can, for example, be 100 to 10,000, further set to 200 to 5,000, further set to 250 to 3,000, further set to 300 to 5,000, and further set to 300 to 3,000, etc.

[0128] In addition, the mass-average molecular weight of the peptides was determined by gel permeation chromatography (GPC) using polyethylene glycol as the standard.

[0129] When this hair-care composition contains peptides as a touch-enhancing ingredient, the proportion of peptides is not particularly limited. However, when the total weight of the hair-care composition is 100% by mass, the lower limit can be 0.0001% by mass or more. It can be further set to 0.0005% by mass or more, or even 0.001% by mass or more. On the other hand, the upper limit can be set to 5% by mass or less, or even 4% by mass or less, or even 2% by mass or less. These upper and lower limits can be combined arbitrarily. For example, it can be set to 0.0001 to 5% by mass, or even 0.0005 to 4% by mass, or even 0.001 to 2% by mass. This effectively achieves a touch-enhancing effect. Furthermore, the above-mentioned mass percentages refer to the content at the time of use.

[0130] Among the aforementioned silicones, examples include dimethyl polysiloxane (polydimethylsiloxane), methylphenyl polysiloxane, decamethylcyclopentasiloxane, dodecylcyclohexasiloxane, hydroxyl-terminated dimethyl polysiloxane, high-polymer silicones with an average degree of polymerization of 650-10000, polyether-modified silicones, amino-modified silicones such as aminoethylaminopropylsiloxane-dimethylsiloxane copolymer (aminopolydimethylsiloxane), betaine-modified silicones, alkyl-modified silicones, alkoxy-modified silicones, mercapto-modified silicones, carboxyl-modified silicones, and fluorinated silicones. Only one of these can be used, or two or more can be used in combination.

[0131] When this hair-care composition contains silicone as a touch-improving ingredient, its content is not limited. When the total hair-care composition is set at 100% by mass, its lower limit can be set to 0.01% by mass or more. It can be further set to 0.05% by mass or more, and further to 0.1% by mass or more. On the other hand, its upper limit can be set to 30% by mass or less, and further to 20% by mass or less, and further to 10% by mass or less. These upper and lower limits can be combined arbitrarily. For example, it can be set to 0.01 to 30% by mass, further to 0.05 to 20% by mass, and further to 0.1 to 10% by mass. Thus, the effect of improving hair touch can be effectively obtained. Furthermore, the above-mentioned mass percentages refer to the content at the time of use.

[0132] Hair-use compositions that use hair as a hair-penetration-enhancing ingredient include, for example, hair-dyeing shampoos containing one or more selected from amino acids and amino acid-like components, and peptides; and hair-dyeing treatments containing one or more selected from amino acids and amino acid-like components, and peptides. Furthermore, examples include hair-dyeing treatments that use dyes (especially basic dyes) and one or more touch-enhancing ingredients selected from the group consisting of amino acids and amino acid-like components, and peptides as hair-penetration-enhancing ingredients.

[0133] [3] Oily ingredients

[0134] Oily components are those that form the oil phase and are usually oil-soluble.

[0135] Examples of oily components include higher alcohols, hydrocarbons, fats, waxes, higher fatty acids, esters, fluorinated oils, and alkyl glycerol ethers. Only one of these can be used, or two or more can be used simultaneously.

[0136] When the hair-care composition contains an oily component, its proportion is not limited. However, when the total hair-care composition is set at 100% by mass, the lower limit can be set to 2% by mass or more, further to 5% by mass or more, further to 6% by mass or more, further to 7% by mass or more, further to 8% by mass or more, further to 9% by mass or more, further to 10% by mass or more, or further to 11% by mass or more. On the other hand, the upper limit can be set, for example, to 25% by mass or less, further to 20% by mass or less, further to 18% by mass or less, further to 16% by mass or less, further to 15% by mass or less, further to 14% by mass or less, or further to 13% by mass or less. These upper and lower limits can be combined arbitrarily. For example, they can be 2 to 25% by mass, 5 to 20% by mass, 6 to 18% by mass, 7 to 16% by mass, 8 to 15% by mass, 9 to 15% by mass, 10 to 14% by mass, or 11 to 13% by mass. In addition, the above-mentioned percentage content refers to the content at the time of use.

[0137] Furthermore, particularly in hair dyes where the hair composition is a complex formulation (e.g., an oxidative hair dye), the content of the oily component (100% by mass of the total hair dye) can have a lower limit of 8% by mass or more, and can be further set to 10% by mass or more, further set to 11% by mass or more, and further set to 12% by mass or more. On the other hand, its upper limit can be set to 17% by mass or less, and can be further set to 15% by mass or less, further set to 14% by mass or less, and further set to 13% by mass or less. These upper and lower limits can be combined arbitrarily. For example, it can be set to 8 to 17% by mass, it can be set to 10 to 15% by mass, it can be set to 11 to 14% by mass, and it can be set to 12 to 13% by mass.

[0138] Furthermore, when the first agent (typically containing at least dye and alkali) of a hair dye compound containing a hair-applied composition comprises an oily component, its content ratio (100% by mass of the first agent as a whole) can be at least 2% by mass, and can be further at least 3% by mass, and can be further at least 4% by mass, and can be further at least 5% by mass, and can be further at least 6% by mass, and can be further at least 7% by mass, and can be further at least 8% by mass, and can be further at least 8.5% by mass. On the other hand, its upper limit can be 20% by mass or less, and can be further at least 18% by mass, and can be further at least 15% by mass, and can be further at least 13% by mass, and can be further at least 12.5% ​​by mass. These upper and lower limits can be arbitrarily combined. For example, it can be 2 to 20% by mass, 3 to 18% by mass, 4 to 18% by mass, 5 to 15% by mass, 6 to 13% by mass, 7 to 13% by mass, 8 to 12.5% ​​by mass, and 8.5 to 12.5% ​​by mass.

[0139] Furthermore, when the second agent (which typically contains at least an oxidizing agent) of a hair dye compound consisting of a hair-applied composition contains an oily component, the lower limit of its content percentage (100% by mass of the second agent as a whole) can be set to 5% by mass or more, and can be further set to 7% by mass or more, and can be further set to 9% by mass or more, and can be further set to 11% by mass or more, and can be further set to 12% by mass or more, and can be further set to 13% by mass or more. On the other hand, its upper limit can be set to 20% by mass or less, and can be further set to 19% by mass or less, and can be further set to 18% by mass or less, and can be further set to 17% by mass or less, and can be further set to 16% by mass or less.

[0140] On the other hand, when the hair composition is a single-agent hair dye (e.g., a hair dye conditioning agent), the content of the oily component (100% by mass of the total hair dye) can be at least 2% by mass, and further at least 5% by mass, further at least 6% by mass, and further at least 7% by mass. On the other hand, the upper limit can be 20% by mass or less, further at least 17% by mass, further at least 15% by mass, and further at least 12% by mass. These upper and lower limits can be combined arbitrarily. For example, it can be set to 2-20% by mass, 5-17% by mass, 6-15% by mass, or 7-12% by mass.

[0141] Higher alcohols can be alcohols having a carbon chain with 6 or more carbon atoms. For example, higher alcohols having 8 or more but less than 40 carbon atoms are preferred, and higher alcohols having 14 or more but less than 22 carbon atoms are even more preferred. Furthermore, the backbone can be saturated or unsaturated, and can be straight-chain or branched. From the viewpoint of improving ease of application, straight-chain higher alcohols with 14 to 22 carbon atoms are more preferred. It is believed that using straight-chain higher alcohols with 14 to 22 carbon atoms can improve the retention force of micro / nano bubbles, thereby improving the coating's spreadability.

[0142] Examples of higher alcohols include lauryl alcohol, myristyl alcohol, cetyl alcohol, stearyl alcohol, cetyl alcohol, arachidyl alcohol, behenyl alcohol, oleyl alcohol, linoleyl alcohol, linolenic acid alcohol, 2-hexyldecyl alcohol, isostearyl alcohol, 2-octyldodecyl alcohol, decyltetradecyl alcohol, lanolin alcohol, phytosterols, and cholesterol. One of these can be used alone, or two or more can be used in combination.

[0143] Examples of straight-chain higher alcohols with 14 to 22 carbon atoms include myristol (14-carbon), cetyl alcohol (16-carbon), stearyl alcohol, oleyl alcohol, linoleyl alcohol, linolenic acid alcohol (18-carbon), a mixture of cetyl alcohol (16-carbon) and linolenic acid alcohols, arachidonic acid (20-carbon), and behenyl alcohol (22-carbon). Only one of these can be used, or two or more can be used in combination.

[0144] When this hair-applied composition contains an oily component and includes higher alcohols as an oily component, the proportion of these components is not limited. When the total hair-applied composition is 100% by mass, the lower limit can be 0.5% by mass or more. It can be further set to 1% by mass or more, 2% by mass or more, or 3% by mass or more. On the other hand, the upper limit can be 20% by mass or less, 15% by mass or less, or 10% by mass or less. These upper and lower limits can be combined arbitrarily. For example, it can be set to 0.5 to 20% by mass, 1 to 15% by mass, 2 to 15% by mass, or 3 to 10% by mass. This effectively improves the ease of spreading. Furthermore, the above-mentioned mass percentages refer to the content used in the application.

[0145] Furthermore, the content of higher alcohols (100% by mass of the total hair dye) in hair dye compositions, particularly when the hair dye composition is a complex formulation, can have a lower limit of 2.0% by mass or more, and can be further 2.5% by mass or more, and can be further 3.0% by mass or more, and can be further 3.5% by mass or more, and can be further 4.0% by mass or more. On the other hand, its upper limit can be set to 12% by mass or less, and can be further set to 10% by mass or less, and can be further set to 8% by mass or less, and can be further set to 7% by mass or less. These upper and lower limits can be combined arbitrarily. For example, it can be set to 2 to 12% by mass, 2.5 to 10% by mass, 3 to 8% by mass, and 4 to 7% by mass.

[0146] Furthermore, when the first agent (typically containing at least a dye and an alkali) of a hair dye compound comprising a hair-use composition contains a higher alcohol, its content percentage (100% by mass of the first agent as a whole) can be at least 2% by mass, and can be further at least 3% by mass, and can be further at least 4% by mass, and can be further at least 4.5% by mass. On the other hand, its upper limit can be set to 10% by mass or less, and can be further at least 9% by mass, and can be further at least 8% by mass, and can be further at least 7% by mass. These upper and lower limits can be combined arbitrarily. For example, it can be set to 2 to 10% by mass, 3 to 9% by mass, and 4 to 7% by mass.

[0147] Furthermore, when the second agent (usually containing at least an oxidizing agent) of a hair dye compound containing a hair-applied composition comprises a higher alcohol, the lower limit of its content percentage (100% by mass of the second agent as a whole) can be set to 2% by mass or more, further to 3% by mass or more, further to 4% by mass or more, or further to 4.5% by mass or more. On the other hand, the upper limit can be set to 10% by mass or less, further to 8% by mass or less, or further to 6% by mass or less. These upper and lower limits can be combined arbitrarily. For example, they can be set to 2 to 10% by mass, 3 to 8% by mass, or 4 to 6% by mass.

[0148] On the other hand, when the hair composition is a single-agent hair dye (e.g., a hair dye conditioning agent), the lower limit of the content of higher alcohols (100% by mass of the total hair dye) can be 0.5% by mass or more, further 1% by mass or more, further 2% by mass or more, and further 3% by mass or more. On the other hand, the upper limit can be set to 15% by mass or less, further 12.5% ​​by mass or less, and further 10% by mass or less. These upper and lower limits can be combined arbitrarily. For example, it can be set to 0.5 to 15% by mass, 1 to 12.5% ​​by mass, 2 to 10% by mass, or 3 to 10% by mass.

[0149] When this hair-care composition contains an oily component and further includes higher alcohols as the oily component, the higher alcohols may contain only one type, but preferably two or more. It is believed that when two or more higher alcohols are contained, the retention power of micro- and nano-bubbles within the hair-care composition is improved, resulting in superior ease of spreadability. The two or more higher alcohols may be any combination, but preferably a combination containing at least stearyl alcohol, and may be (1) a combination containing stearyl alcohol and cetyl alcohol, (2) a combination containing stearyl alcohol and betaine alcohol, or (3) a combination containing stearyl alcohol and arachidyl alcohol. These may be used individually or in combination with two or more.

More specifically, within the above range, stearyl alcohol may be 0.1 to 8% by mass relative to 100% of the total hair composition, and may be further set to 0.5 to 6% by mass, or may be further set to 1 to 5% by mass. In addition, the above mass percentages are the content at the time of use.

[0153] In the above, in the combination containing stearyl alcohol and arachidyl alcohol in (3), the stearyl alcohol and arachidyl alcohol may be contained in a mass ratio of 1:1 to 10, and may be further set to 1:2 to 8, or further set to 1:2.5 to 4.0. More specifically, within the above range, stearyl alcohol may be 0.1 to 8% by mass relative to 100% of the total hair composition, and may be further set to 0.5 to 6% by mass, or further set to 0.8 to 4.0% by mass.

When the total hair-applied composition is set at 100% by mass, the lower limit can be set to 0.05% by mass or more. It can be further set to 0.1% by mass or more, and further to 0.5% by mass or more. On the other hand, the upper limit can be set to 60% by mass or less, and further to 50% by mass or less, and further to 40% by mass or less. These upper and lower limits can be combined arbitrarily. For example, it can be set to 0.05 to 60% by mass, further to 0.1 to 50% by mass, and further to 0.5 to 40% by mass. This effectively improves the ease of spreading. Furthermore, the above-mentioned mass percentages refer to the content used in the application.

[0163] When this hair-applied composition contains an oily component and includes esters as the oily component, the proportion of these components is not limited. When the total hair-applied composition is set at 100% by mass, the lower limit can be set to 0.005% by mass or more.

This effectively improves the ease of spreading. Furthermore, the above-mentioned mass percentages refer to the content at the time of use.

[0164] When this hair-applied composition is a hair dye composition, it may contain other ingredients besides micro-nano bubbles, hair-penetrating components, and oily components. Examples of these other ingredients include water-soluble polymers, solubilizers, surfactants, pH adjusters, preservatives, antioxidants, stabilizers, and plant extracts (excluding the aforementioned hair-penetrating components and oily components). Only one of these ingredients may be used, or two or more may be used in combination.

[0165] As water-soluble polymers, examples include water-soluble natural polymers, water-soluble semi-synthetic polymers, water-soluble synthetic polymers, and water-soluble inorganic polymers. Only one type of these can be used, or two or more can be used in combination.

[0166] Examples of natural, water-soluble polymers include guar gum, locust bean gum, quince seed gum, carrageenan, galactomannan, gum arabic, astragalus gum, pectin, mannan, xanthan gum, dextran, succinyl glucan, cardran (gelatin), hyaluronic acid, gelatin, casein, albumin, collagen, and dextrin.

[0167] Examples of semi-synthetic water-soluble polymers include cellulose-based water-soluble polymers, cationic guar gum, starch phosphate, propylene glycol alginate, and alginate. One or more of these can be used.

[0168] In addition, examples of water-soluble cellulose polymers include methylcellulose, ethylcellulose, hydroxyethylcellulose, hydroxyethylcellulose dimethyl diallyl ammonium chloride, hydroxypropylcellulose, carboxymethylcellulose, sodium carboxymethylcellulose, hydroxypropyl methylcellulose, and cationic cellulose.

These can be used individually or in combination with two or more monomers.

[0170] When this hair-applied composition contains a water-soluble polymer, its content ratio is not limited. However, when the total hair-applied composition is set at 100% by mass, its lower limit can be set to 0.01% by mass or more. It can be further set to 0.05% by mass or more, and further set to 0.1% by mass or more. On the other hand, its upper limit can be set to 10% by mass or less, and further set to 5% by mass or less, and further set to 1% by mass or less. These upper and lower limits can be combined arbitrarily. For example, it can be 0.01 to 10% by mass, and further set to 0.05 to 5% by mass, and further set to 0.1 to 1% by mass. This effectively improves the ease of spreading. In addition, the above-mentioned mass percentage content is the content at the time of use.

[0171] When the hair-making composition contains the aforementioned oily components, and / or when the hair-making composition contains the aforementioned water-soluble polymers, the effect of micro / nanobubbles can be obtained more significantly. The reason for this is not yet certain, but it can be considered that the viscosity of the hair-making composition increases when these components are present. That is, it is assumed that these components function as thickening agents, and in hair-making compositions containing thickening agents, the retention force of micro / nanobubbles is increased compared to hair-making compositions without these components due to the thickening effect; therefore, it can be considered that the effect of micro / nanobubbles can be obtained more significantly.

[0172] The viscosity of this hair-applied composition is not limited; for example, the lower limit of the viscosity of this hair-applied composition can be set to 10,000 mPa·s or more. This improves the retention of micro / nano bubbles, resulting in a more significant improvement in permeability and coatability. The lower limit of viscosity can be further set to 3,000 mPa·s or more, 7,000 mPa·s or more, or 9,500 mPa·s or more. On the other hand, the upper limit can be set to 30,000 mPa·s or less. These upper and lower limits can be combined arbitrarily. For example, they can be set to 3,000 to 30,000 mPa·s, 7,000 to 30,000 mPa·s, or 9,500 to 30,000 mPa·s. If the above viscosity is met during storage, it is preferable from the perspective of easily maintaining microbubbles for a long time. By meeting the above viscosity during use, the coatability can be adjusted without causing microbubbles to escape, which is therefore preferable.

[0206] [Example]

[0207] The present invention will now be described in more detail with reference to embodiments, but these embodiments are merely examples for the purpose of illustration and the present invention is not limited to these embodiments in any sense.

[0208] [1] Preparation and evaluation of oxidative hair dye

[0209] (1) Preparation of the first agent (for oxidative hair dye)

[0210] The components shown in Table 1 were mixed in the mass ratios shown in Table 1 (total 100% by mass) to prepare a total of 10 first agents for Examples 1-5 and Comparative Examples 1-5.

[0211] In addition, among the hair penetration ingredients in Table 1, toluene-2,5-diamine sulfate, resorcinol, p-aminophenol, and m-aminophenol are equivalent to oxidative dyes, strong ammonia (28%) and 70% monoethanolamine are equivalent to alkalis, and PEG400 is equivalent to moisturizing ingredients.

[0212] Furthermore, "Purified Water 1 (containing MNB)" in Table 1 refers to a liquid in which 0.5-1 L of purified water was homogenized at 5000 rpm for 10 minutes. When this liquid was irradiated with a laser, the light path was visually identifiable, thus confirming the presence of micro / nanobubbles. "(Containing MNB)" indicates the presence of micro / nanobubbles. On the other hand, "Purified Water 2 (without MNB)" in Table 1 refers to purified water before homogenization. When this liquid was irradiated with a laser, the light path was not visually identifiable, thus not confirming the presence of micro / nanobubbles. "(Without MNB)" indicates that no micro / nanobubbles were observed. Therefore, the first agents of Examples 1-5 prepared using purified water 1 contained micro / nanobubbles, while the first agents of Comparative Examples 1-5 prepared using purified water 2 did not contain micro / nanobubbles.

[0213] (2) Preparation of the second agent

[0214] Mix the components shown in Table 2 at the mass ratios shown in Table 2 (total 100% by mass) to prepare two second agents, A and B.

[0215] In addition, hydrogen peroxide water (35%), which is a hair penetration component in Table 2, is equivalent to an oxidant.

[0216] Furthermore, the preparation of the second agent also uses the same methods as the preparation of the first agent: "purified water 1 (containing MNB)" and "purified water 2 (without MNB)". Therefore, "A" prepared using purified water 1 contains micro-nano bubbles, while "B" prepared using purified water 2 does not contain micro-nano bubbles.

[0217] (3) Evaluation of hair dyeing power

[0218] The first agent of Examples 1-5 prepared in (1) above was mixed with the second agent A prepared in (2) above at a mass ratio of 1:1 to obtain the oxidative hair dye of each example. As described above, the reagents of Examples 1-5 prepared using "purified water 1 (containing MNB)" contain micro-nano bubbles.

[0219] On the other hand, the first agent of each of Comparative Examples 1 to 5 prepared in (1) above was mixed with the second agent B prepared in (2) above at a mass ratio of 1:1 to obtain the oxidative hair dye of each comparative example. As described above, the agents of Comparative Examples 1 to 5 prepared using "purified water 2 (without MNB)" did not contain micro-nano bubbles.

[0220] The oxidative hair dyes obtained in Examples 1-5 and Comparative Examples 1-5 were applied to 10cm long evaluation samples of white hair (manufactured by Beaulax). The application was carried out at a rate of 3g of oxidative hair dye per 1g of hair sample. The hair samples coated with the oxidative hair dye were then left to stand for 25 minutes, followed by rinsing with water three times (using 500g of water) and drying using a dryer.

[0221] Under standard light, professional hair dyeing evaluators visually observed the hair strand samples after the above-mentioned hair dyeing treatment to evaluate the dyeing ability of each oxidative hair dye. During the evaluation, the results of each oxidative hair dye in Comparative Examples 1-5 were compared with the results of each oxidative hair dye in the corresponding Examples 1-5 to evaluate the degree of improvement in dyeing ability. Before the evaluation, all evaluators evaluated the standard samples. After standardizing the scores of each evaluation criterion, 10 evaluators conducted an objective evaluation. The evaluation was based on scores corresponding to the five levels of criteria shown in 1 to 5 below. Furthermore, the evaluation was conducted by selecting the value from the scores that was closest to each group member's own evaluation.

[0222] 5: The hair dyeing effect is greatly improved.

[0223] 4: Increased hair dyeing power

[0224] 3: Slightly higher hair dyeing power.

[0225] 2: A slight improvement in hair dyeing power has been confirmed.

[0226] 1: No improvement in hair dyeing power has been confirmed.

[0227] Next, the average score of all group members was calculated. An average score of 3.5 or higher was designated "Excellent: 5", 3 or higher but less than 3.5 was designated "Good: 4", 2.5 or higher but less than 3 was designated "Pass: 3", 2 or higher but less than 2.5 was designated "Slightly Poor: 2", and less than 2 was designated "Poor: 1". These results are shown in the "Hair Dyeing Power" column of Table 1.

[0228] (4) Evaluation of the extension of oxidative hair dye

[0229] The "spreading of the formulation" when the oxidative hair dye was applied to the hair strand sample for evaluation in (3) above was evaluated. During the evaluation, the extent of improvement in the spread of each oxidative hair dye in Comparative Examples 1-5 was evaluated. Furthermore, before the evaluation, all evaluators evaluated the standard samples, and after standardizing the scores of each evaluation criterion, 10 evaluators conducted an objective evaluation. The evaluation was based on scores corresponding to the five levels of criteria shown in 1 to 5 below. Additionally, the evaluation was conducted by selecting the value from the scores that was closest to each group member's own evaluation.

[0230] 5: The formulation's extensibility has been greatly improved.

[0231] 4: Improved formulation extensibility

[0232] 3: The improvement in formulation extension is slightly higher.

[0233] 2: A slight improvement in the formulation's spread was confirmed.

[0234] 1: No improvement in formulation extension was confirmed.

[0235] Then, the average score of all group members was calculated. An average score of 3.5 or above was set as "Excellent: 5", 3 or above but less than 3.5 as "Good: 4", 2.5 or above but less than 3 as "Pass: 3", 2 or above but less than 2.5 as "Slightly Poor: 2", and less than 2 as "Poor: 1", which were used as the evaluation results.

[0236] In this embodiment, the results are shown in the "Extension of Formulation" column of Table 1. Furthermore, evaluation results of 2 points or higher are used as examples for evaluation.

[0243] The components shown in Table 3 were mixed in the mass ratios shown in Table 3 (total 100% by mass) to prepare the first agents of Example 6 and Comparative Example 6.

[0244] In addition, among the hair penetration ingredients in Table 3, strong ammonia (28%) and 70% monoethanolamine are equivalent to alkali agents, and PEG400 is equivalent to moisturizing ingredients.

[0245] In addition, the situation regarding "Purified Water 1 (containing MNB)" and "Purified Water 2 (without MNB)" in Table 3 is the same as that in Table 1.

[0246] (2) Second reagent

[0247] Similarly, the two second agents A and B prepared in [1] (2) above are used (Table 2).

[0248] (3) Evaluation of brightness

[0249] The first agent and the second agent A prepared in (1) above were mixed at a mass ratio of 1:1 to obtain the decolorizing agent of Example 6. As described above, the decolorizing agent of Example 6 prepared using "purified water 1 (containing MNB)" contains micro-nano bubbles.

[0250] On the other hand, the first agent and the second agent B of Comparative Example 6 prepared in (1) above were mixed at a mass ratio of 1:1 to obtain the decolorizing agent of the comparative example. As described above, the decolorizing agent of Comparative Example 6 prepared using "purified water 2 (without MNB)" does not contain micro-nano bubbles.

[0251] The decolorizing agents obtained in Example 6 and Comparative Example 6 were applied to 10 cm long evaluation samples of black hair (manufactured by Beaulax). The application was carried out at a rate of 3 g of decolorizing agent per 1 g of hair sample. The hair samples coated with the decolorizing agent were then left to stand for 25 minutes, and then washed three times with water (500 g of water) before being dried using a dryer.

[0252] Under standard light, professional evaluators visually observed the decolorized hair samples obtained above and evaluated the brightness of the decolorizing agents in each case. During the evaluation, the results of the decolorizing agent in Comparative Example 6 were compared with the results of the decolorizing agent in the corresponding Example 6 to evaluate the degree of brightness improvement. Before the evaluation, all evaluators evaluated the standard samples. After standardizing the scores of each evaluation criterion, 10 evaluators conducted an objective evaluation. The evaluation was based on scores corresponding to the five levels of criteria shown in 1 to 5 below. Furthermore, the evaluation was conducted by selecting the value from the scores that best matched each group member's own evaluation.

[0253] 5: The brightness has been greatly improved.

[0254] 4: High brightness improvement

[0255] 3: Brightness increase is slightly higher.

[0256] 2: A slight increase in brightness has been confirmed.

[0257] 1: No increase in brightness was confirmed.

[0258] Next, the average score of all group members was calculated. An average score of 3.5 or higher was designated "Excellent: 5", 3 or higher but less than 3.5 as "Good: 4", 2.5 or higher but less than 3 as "Pass: 3", 2 or higher but less than 2.5 as "Slightly Poor: 2", and less than 2 as "Poor: 1". These were used as the evaluation results. The results are shown in the "Brightness" column of Table 3.

[0259] (4) Evaluation of the extension of the decolorizing agent

[0260] The "spreading of the formulation" when the decolorizing agent was applied to the hair strand sample for evaluation in (3) above was evaluated. During the evaluation, the degree of improvement in the spreading of the decolorizing agent of Example 6 was evaluated relative to the spreading of the decolorizing agent of Comparative Example 6. Furthermore, before the evaluation, all evaluators evaluated the standard samples, and after standardizing the scores of each evaluation criterion, 10 evaluators conducted an objective evaluation. The evaluation was based on scores corresponding to the five levels of criteria shown in 1 to 5 below. Additionally, the evaluation was conducted by selecting the value from the scores that was closest to each group member's own evaluation.

[0261] 5: The formulation's extensibility has been greatly improved.

[0262] 4: Improved formulation extensibility

[0263] 3: The improvement in formulation extension is slightly higher.

[0264] 2: A slight improvement in the formulation's extensibility has been confirmed.

[0265] 1: No improvement in formulation extension was confirmed.

[0266] Subsequently, the average score of all team members was calculated. An average score of 3.5 or higher was designated "Excellent: 5", 3 or higher but less than 3.5 was designated "Good: 4", 2.5 or higher but less than 3 was designated "Acceptable: 3", 2 or higher but less than 2.5 was designated "Slightly Poor: 2", and less than 2 was designated "Poor: 1". These were used as evaluation results. The results are shown in the "Formulation Extension" column of Table 3. Furthermore, evaluation results of 2 or higher were used as examples for evaluation.

[0267] [Table 3]

[0268]

[0269] [3] Preparation and evaluation of hair dyeing and conditioning agents

[0270] (1) Preparation of hair dyeing and conditioning agents

[0271] The components shown in Table 4 were mixed in the mass ratios shown in Table 4 (total 100% by mass) to prepare two hair dyeing and conditioning agents for Examples 7-8 and Comparative Examples 7-8.

[0272] Furthermore, in the hair penetration ingredients listed in Table 4, HC Blue 2, Alkaline Tea 16, and HC Yellow 4 are equivalent to direct dyes; glycerin and 1,3-butanediol are equivalent to moisturizing ingredients; and taurine and premix are equivalent to touch-enhancing ingredients.

The "purified water" used in the preparation of this premix is ​​equivalent to "purified water 2 (without MNB)".

[0273] Furthermore, in the preparation of the hair dye conditioning agent, "purified water 1 (containing MNB)" and "purified water 2 (without MNB)" were used in the same way as in the preparation of the oxidative hair dye. Therefore, the hair dye conditioning agents of Examples 7-8 prepared using purified water 1 contained micro-nano bubbles. On the other hand, the hair dye conditioning agents of Comparative Examples 7-8 prepared using purified water 2 did not contain micro-nano bubbles.

[0274] (2) Evaluation of hair dyeing power

The hair samples coated with the hair dyeing agent were then left to stand for 25 minutes, and then washed three times with water (using 500g of water) and dried using a dryer.

[0276] Under standard light, professional evaluators visually observed the hair strand samples after the aforementioned hair dyeing treatment to evaluate the dyeing ability of each hair dyeing treatment. During the evaluation, the results of the hair dyeing treatment in Comparative Example 7 were compared with the results of the corresponding hair dyeing treatment in Example 7 to assess the degree of improvement in dyeing ability. Before the evaluation, all evaluators conducted standard sample evaluations. After standardizing the scores of each evaluation criterion, 10 evaluators conducted objective evaluations. The evaluation was based on scores corresponding to the five levels of criteria shown in 1 to 5 below. Furthermore, the evaluation was conducted by selecting the score that best matched each group member's own evaluation.

[0277] 5: The hair dyeing effect is greatly improved.

[0278] 4: Increased hair dyeing power

[0279] 3: Slightly higher hair dyeing power.

[0280] 2: A slight improvement in hair dyeing power has been confirmed.

[0282] Next, the average score of all group members was calculated. An average score of 3.5 or higher was designated "Excellent: 5", 3 or higher but less than 3.5 was designated "Good: 4", 2.5 or higher but less than 3 was designated "Pass: 3", 2 or higher but less than 2.5 was designated "Slightly Poor: 2", and less than 2 was designated "Poor: 1". These results are shown in the "Hair Dyeing Power" column of Table 4.

[0283] (3) Evaluation based on the moisturizing effect of hair dyeing and conditioning products

[0284] The moisturizing effect of the hair strand samples after dyeing treatment obtained through (2) above was evaluated. In Table 4, 1,3-butanediol and glycerin are the moisturizing components in the hair penetration ingredients. During the evaluation, the degree of improvement in moisturizing effect brought by the hair dyeing treatment agent of Example 7 was evaluated relative to that brought by the hair dyeing treatment agent of Comparative Example 7. In addition, before the evaluation, all evaluators evaluated the standard samples, and after standardizing the scores of each evaluation criterion, 10 people conducted an objective evaluation. The evaluation was based on the scores corresponding to the 5 levels of the criterion shown in 1 to 5 below. In addition, the evaluation was carried out by selecting the value that is closest to the evaluation of each group member from the scores.

[0285] 5: The moisturizing effect is greatly improved.

[0286] 4: Improves moisturizing effect

[0287] 3: The moisturizing effect is slightly higher.

[0288] 2: Slightly confirmed improvement in moisturizing effect

[0289] 1: No improvement in moisturizing effect confirmed.

[0290] Next, the average score of all group members was calculated. An average score of 3.5 or higher was designated "Excellent: 5", 3 or higher but less than 3.5 as "Good: 4", 2.5 or higher but less than 3 as "Pass: 3", 2 or higher but less than 2.5 as "Slightly Poor: 2", and less than 2 as "Poor: 1". These were used as the evaluation results. The results are shown in the "Nourishment" column of Table 4.

[0291] (4) Evaluation of tactile sensation

[0292] The tactile feel of the hair strand samples obtained through the hair dyeing treatment described in (2) above was evaluated. The evaluation was conducted by professional evaluators, assessing the degree of improvement in the tactile feel of the hair strand samples from Examples 7-8 compared to those from Comparative Examples 7-8. Before the evaluation, all evaluators evaluated the standard samples. After standardizing the scores of each evaluation criterion, 10 people conducted an objective evaluation. The evaluation was based on scores corresponding to the five levels of criteria shown in 1 to 5 below. Furthermore, the evaluation was conducted by selecting the score that best matched the evaluation of each group member.

[0293] 5: The improvement in tactile sensation is very significant.

[0294] 4: Improved tactile sensation

[0295] 3: The improvement in tactile sensation is slightly higher.

[0296] 2: A slight improvement in tactile sensation was observed.

[0297] 1: No improvement in tactile sensation confirmed.

[0298] Next, the average score of all group members was calculated. An average score of 3.5 or higher was designated "Excellent: 5", 3 or higher but less than 3.5 was designated "Good: 4", 2.5 or higher but less than 3 was designated "Pass: 3", 2 or higher but less than 2.5 was designated "Slightly Poor: 2", and less than 2 was designated "Poor: 1". These were used as the evaluation results. The results are shown in the "Tactile Feel" column of Table 4.

[0299] (5) Evaluation of the extension effect of hair dyeing and conditioning products

[0300] The "spreading of the formulation" when the hair dyeing agent was applied to the hair strand sample for evaluation in (2) above was evaluated. During the evaluation, the degree of improvement in the spread of the hair dyeing agents of Examples 7-8 was evaluated compared to the spread of the hair dyeing agents of Comparative Examples 7-8. Furthermore, before the evaluation, all evaluators evaluated the standard samples, and after standardizing the scores of each evaluation criterion, 10 evaluators conducted an objective evaluation. The evaluation was based on scores corresponding to the five levels of criteria shown in 1 to 5 below. Additionally, the evaluation was conducted by selecting the value from the scores that was closest to each group member's own evaluation.
