Description

[Technical field]

[0001] The present invention relates to a multi-component hair cosmetic composition and a method for using the same, and more particularly to a multi-component hair cosmetic composition containing two or more low-viscosity cosmetic compositions and a method for using the same. [Background technology]

[0002] In recent years, there has been an increasing demand for more advanced hair damage care. Hair damage is diverse, including damage caused by washing, hair styling, hair dryer, exposure to ultraviolet light, and chemical treatment such as bleaching, dyeing, and decoloring. The frequency of such damage has been increasing in recent years, and with this trend, the demand for damage care has also increased. Hair cosmetics used for the purpose of exerting such advanced treatment effects are used in a formulation called a cream formulation. That is, it is a hair cosmetic that has a high viscosity and is in a cream-like state. Such a technology is disclosed in the following Patent Document 1. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2018-150249 A Summary of the Invention [Problem to be solved by the invention]

[0004] Patent Document 1 aims to provide a conditioner composition that has an excellent hair conditioning effect, is easy to spread when applied, and has stability as a formulation (Patent Document 1

[0006] ), and contains (A) an amidoamine type surfactant, (B) a monoalkyl quaternary ammonium salt type surfactant, (C) a linear higher alcohol having 16 to 22 carbon atoms, (D) a surfactant having a kinetic viscosity of 4,000,000 mm 2Patent Document 1 discloses a conditioner composition (claim 1) that contains a highly polymerized dimethyl silicone having a viscosity of 1 Pa·s or more, (E) an amino-modified silicone, and (F) a polyether-modified silicone, all in a specific range of mass ratio (A / B), total mass (D+E+F), and mass ratio [D / (E+F)]. It also discloses that the preferred properties of the composition are 1 Pa·s to 20 Pa·s at 25°C (Patent Document 1

[0048] ).

[0005] As a method for realizing the above-mentioned hair damage care, there exists a multi-component hair cosmetic that combines multiple types of hair cosmetics to provide a high level of treatment effect. In such a multi-component hair cosmetic, when multiple cream-type hair cosmetics are used, the hair tends to feel too heavy in terms of current market demands. That is, in recent years, there has been a demand for hair that does not feel heavy and yet has a high level of treatment effect. On the other hand, the use of a low-viscosity hair cosmetic has a problem that it is difficult to provide a manageable feel effect, among other treatment effects, and it has been difficult to prepare a multi-component hair cosmetic that can meet the current market demands.

[0006] The present invention has been made in view of the above-mentioned circumstances, and has an object to provide a multi-component hair cosmetic composition that can impart an excellent treatment effect while making the feel of hair after treatment lighter than before, and a method for using the same. [Means for solving the problem]

Effect of the Invention

[0008] The multi-component hair cosmetic composition of the present invention can impart an excellent treatment effect while making the feel of the hair after treatment lighter than in the past. According to the method of using the multi-component hair cosmetic composition of the present invention, it is possible to impart an excellent treatment effect while making the feel of the hair after treatment lighter than before. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] The present invention will be described below based on specific embodiments. However, the present invention is not limited to these embodiments. These embodiments are merely examples shown for the sake of convenience, and the present invention is not limited to these in any sense. The present invention can be modified in various ways depending on the purpose and application. In addition, all publications, patents, and patent applications cited in this specification are incorporated herein by reference as they are.

[0010] In this specification, unless otherwise specified, "%" means "% by mass" and "parts" means "parts by mass". A numerical range connected with "~" means a numerical range including the numerical values ​​before and after "~" as the lower and upper limits. When multiple upper limits and / or multiple lower limits are indicated for a numerical range, even if not specified, it is assumed that the numerical range definition combining at least the maximum value of the upper limit definition and the minimum value of the lower limit definition is directly stated, and further, all numerical ranges obtained by combining any upper limit value among the upper limits and any lower limit value among the lower limits are included in the embodiments of the present invention. In addition, for some compound names, names conforming to the Japan Cosmetic Industry Association's Ingredient Labeling Name List or INCI (International Nomenclature of Cosmetic Ingredients) names are used. In addition, in the names of some compounds, polyoxyalkylene chains may be abbreviated as "POE" for polyoxyethylene chains and "POP" for polyoxypropylene chains. The numbers in parentheses following these abbreviations indicate the number of moles added. Furthermore, (meth)acrylic acid refers to acrylic acid or methacrylic acid.

[0011] [1] Multi-ingredient hair cosmetic The multi-component hair cosmetic composition of the present invention is a multi-component hair cosmetic composition composed of a plurality of different hair cosmetic compositions, and is characterized in that at least two of the constituent hair cosmetic compositions are low-viscosity cosmetic compositions having a viscosity of 250 mPa s or less.

[0012] (1) Low-viscosity cosmetics A low-viscosity cosmetic is a hair cosmetic having a viscosity of 250 mPa·s or less. By using a hair cosmetic having two or more components and a viscosity of 250 mPa·s or less as a low-viscosity cosmetic constituting a multi-component hair cosmetic, it is possible to impart a feeling of manageability without making the hair feel heavy. The upper limit of this viscosity can be further set to 200 mPa·s or less, further set to 100 mPa·s or less, and further set to 50 mPa·s or less. On the other hand, the lower limit of the viscosity is not limited, but can be set to 0.1 mPa·s or more, 0.5 mPa·s or more, further set to 1 mPa·s or more, and further set to 2 mPa·s or more. These upper and lower limits can be appropriately combined. Therefore, for example, it can be set to 0.1 to 250 mPa·s, 0.5 to 200 mPa·s, 0.5 to 100 mPa·s, or 1 to 50 mPa·s. Furthermore, the low-viscosity cosmetic preparation is not limited in terms of its properties and may be either an emulsion-based composition or a solubilized-based composition, but is preferably a solubilized-based composition. A solubilized-based composition refers to a liquid composition that does not undergo phase separation and remains in a stable one-phase state. This viscosity is measured 60 seconds after starting the measurement under the conditions of 25° C., rotor No. 2, and a rotation speed of 30 rpm.

[0013] The low-viscosity cosmetic may contain any component, but one of the low-viscosity cosmetic compositions may contain an anionic component, and the other of the low-viscosity cosmetic compositions may contain a cationic component. That is, the two may be contained separately. If the anionic component and the cationic component are contained in the same hair cosmetic composition, there is a possibility that a complex will be formed. In this regard, the above possibility can be eliminated by containing the anionic component and the cationic component in different hair cosmetic compositions.

[0014] (2) Anionic components The anionic component is a component that functions as an anion when applied to hair, and usually exists as an anion in the hair cosmetic, but the ionicity in the hair cosmetic is not important. That is, the component may have ionicity or may not have ionicity. Alternatively, the component may exist as a cation in the hair cosmetic and function as an anion when applied to hair. On the other hand, a cationic component is a component that functions as a cation when applied to hair, and usually exists as a cation in the hair cosmetic, but the ionicity in the hair cosmetic does not matter. That is, the component may have ionicity or may not have ionicity. Alternatively, the component may exist as an anion in the hair cosmetic and function as a cation when applied to hair.

[0015] Among the above, examples of the anionic component include naturally occurring anionic components and synthetically occurring (chemically synthesized) anionic components. Among these, examples of naturally occurring anionic components include proteins (proteins having anionic properties), hydrolyzed proteins (hydrolyzed proteins having anionic properties), xanthan gum, carrageenan, sodium alginate, pectin, furcellaran, gum arabic, ghatti gum, karaya gum, tragacanth gum, agar, etc. These may be used alone or in combination of two or more.

[0016] Among the above, the type of protein is not limited, and may be animal protein or vegetable protein. These may be used alone or in combination of two or more. Among these, examples of animal proteins include keratin, collagen, silk, conchiolin, elastin, fibroin, casein, gelatin, etc. These may be used alone or in combination of two or more. On the other hand, examples of vegetable proteins include vegetable proteins obtained from plants such as soybeans, wheat, barley, oats, almonds (including almond seeds, etc.), corn, rice (including rice germ, rice bran, etc.), and potatoes. These may be used alone or in combination of two or more.

[0017] Among the above, the hydrolyzate protein is a product of hydrolysis of protein. The hydrolysis method is not limited, and includes hydrolysis with acid, alkali, enzyme, etc. These may be used alone or in combination of two or more. After hydrolysis, the protein hydrolyzate may be purified as required (e.g., purification by gel filtration, purification by molecular membrane, etc.) so as to increase or decrease the content of a specific peptide, etc., or may not be purified at all.

[0018] On the other hand, examples of synthetic anionic components include polymers (including homopolymers and copolymers) of acidic vinyl monomers or their salts. That is, examples include carboxyvinyl polymers. The acidic vinyl monomer is a compound having an acidic group and a polymerizable vinyl group. Among these, examples of the acidic group include a carboxyl group, a sulfonic acid group, and a phosphoric acid group. These may be used alone or in combination of two or more. Examples of the acidic vinyl monomer include acrylic acid, methacrylic acid, crotonic acid, vinylbenzoic acid, 2-acrylamido-2-methylpropanesulfonic acid, styrenesulfonic acid, vinylsulfonic acid, allylsulfonic acid, methacrylicsulfonic acid, 3-methacrylicpropanesulfonic acid, itaconic acid, maleic acid, fumaric acid, etc. These may be used alone or in combination of two or more. In addition to the acidic vinyl monomer, other monomers copolymerizable with the acidic vinyl monomer may be used. When other monomers are used, their content is preferably 50 mol % or less based on the total structural units constituting the resulting polymer.

[0019] Further, the anionic component may be an anionic surfactant. Examples of the anionic surfactant include alkyl ether sulfate, POE alkyl ether sulfate, alkyl sulfate, alkenyl ether sulfate, alkenyl sulfate, olefin sulfonate, alkane sulfonate, saturated or unsaturated fatty acid salt, alkyl or alkenyl ether carboxylate, α-sulfonic acid salt, N-acylamino acid type surfactant, phosphoric acid mono- or diester type surfactant, sulfosuccinic acid ester, etc. These may be used alone or in combination of two or more. Examples of the counter ion of the anionic group of these surfactants include sodium ion, potassium ion, triethanolamine, etc. These may be used alone or in combination of two or more.

[0020] Among the above, as the anionic component, from the viewpoint of lightness of the feel obtained when the present multi-component hair cosmetic composition is applied to hair, a protein or a hydrolysate thereof is preferred, and as the protein, keratin is more preferred, and hydrolyzed keratin is even more preferred.

[0021] When the hair cosmetic composition constituting the multi-component hair cosmetic composition includes a hair cosmetic composition containing an anionic component, the amount of the anionic component contained in the hair cosmetic composition is not limited, but when the entire hair cosmetic composition (hair cosmetic composition containing an anionic component) is taken as 100% by mass, the lower limit can be 0.001% by mass or more. In this range, the effect of the anionic component can be obtained. This amount can be further 0.01% by mass or more, further 0.05% by mass or more, further 0.1% by mass or more, further 0.15% by mass or more, and further 0.2% by mass or more. On the other hand, the upper limit can be 10% by mass or less, 5% by mass or less, 2.5% by mass or less, 1% by mass or less, 0.75% by mass or less, or 0.5% by mass or less. Within these ranges, the anionic component can be stably maintained within the hair cosmetic composition, and excellent hair treatment action can be obtained when applied to the hair, and the hair can have a lighter feel after treatment. These upper and lower limits can be appropriately combined. Thus, for example, the content can be 0.001 to 10 mass%, 0.01 to 5 mass%, 0.05 to 2.5 mass%, 0.1 to 1 mass%, 0.15 to 0.75 mass%, or 0.2 to 0.5 mass%.

[0022] In addition, in a low-viscosity cosmetic containing keratin or its hydrolysate as an anionic component, any component may be used as a solubilizer, but from the viewpoint of the stability of the anionic component, this allows the dispersion (solubilized state) of the anionic component to be favorably maintained. In particular, even if the anionic component is contained at a high concentration, unintended phenomena such as aggregation of the anionic component can be significantly suppressed. Specifically, when keratin or its hydrolysate, which is an anionic component, is contained in an amount of 0.2% by mass or more relative to 100% by mass of the entire low-viscosity cosmetic, the effect of using polyoxyethylene hydrogenated castor oil as a solubilizer can be significantly obtained.

[0023] (3) Cationic component Examples of the cationic component include naturally occurring cationic components and synthetically occurring (chemically synthesized) cationic components. Of the above, the naturally occurring cationic components are components obtained by cationizing naturally occurring polymers, i.e., cellulose, starch, guar gum, etc. Examples of naturally occurring cationic components include cationic cellulose, cationic starch (e.g., hydroxypropyltrimonium starch chloride), cationic guar gum, cationic chitosan, etc. These may be used alone or in combination of two or more. Furthermore, of the above, examples of cationic cellulose or cationic components based thereon include polyquaternium-4, polyquaternium-10, polyquaternium-67, etc. These may be used alone or in combination of two or more.

[0024] Among the above, synthetic cationic components include components obtained by cationizing chemically synthesized polymers, polymers (including homopolymers and copolymers) using cationized monomers, etc. Cationization can be carried out, for example, by introducing a cationic group such as a quaternary ammonium group.

[0025] Examples of synthetic cationic components include quaternary ammonium salts of various polymers (including homopolymers and copolymers) and polymers (including homopolymers and copolymers) containing polymerizable quaternary ammonium salts as monomers. That is, examples of synthetic cationic components include amino-modified silicones, polyquaterniums (excluding naturally occurring polyquaterniums), silicone quaterniums, etc. Note that polyquaterniums refers to components that include "polyquaternium" in their INCI names, and silicone quaterniums refers to components that include "silicone quaternium" in their INCI names.

[0026] Among the above, amino-modified silicone is a compound in which the methyl group of dimethylpolysiloxane (including linear and cyclic) is replaced with an amino group or a monovalent group having an amino group. That is, it is a compound in which dimethylpolysiloxane (including linear and cyclic) is modified with an amino group or a monovalent group having an amino group. The above explanation of amino modification is intended to explain the above chemical form, and does not specify the manufacturing method. That is, it does not matter whether it is actually manufactured by replacing the methyl group of dimethylpolysiloxane with an amino group or the like. In addition, the amino-modified silicone may be modified in combination with other modifications in addition to the modification for introducing an amino group. Examples of other modifications include terminal hydroxyl group modification, alkyl group modification, phenyl group modification, polyether chain modification, alkoxy group modification, mercapto group modification, carboxy group modification, fluorine modification, betaine modification, etc. These may be used alone or in combination of two or more.

[0027] Examples of amino-modified silicones include amodimethicone (aminoethylaminopropylmethylsiloxane-dimethylsiloxane copolymer), aminopropyldimethicone (aminopropylmethylsiloxane-dimethylsiloxane copolymer), aminoethylaminopropyldimethicone (aminoethylaminopropylmethylsiloxane-dimethylsiloxane copolymer), bis(aminopropyl)dimethicone (polymer with aminopropyl groups introduced at both ends of dimethicone), bis(cetearyl)amodimethicone (polymer with cetearyl groups introduced at both ends of amodimethicone), etc. These may be used alone or in combination of two or more types.

[0028] Among the above, examples of polyquaterniums include polyquaternium-5, polyquaternium-6, polyquaternium-7, polyquaternium-10, polyquaternium-11, polyquaternium-16, polyquaternium-22, polyquaternium-28, polyquaternium-32, polyquaternium-33, polyquaternium-37, polyquaternium-39, polyquaternium-43, polyquaternium-44, polyquaternium-50, polyquaternium-52, polyquaternium-53, polyquaternium-54, polyquaternium-55, polyquaternium-56, polyquaternium-57, polyquaternium-59, polyquaternium-60, polyquaternium-61, polyquaternium-62, polyquaternium-63, polyquaternium-64, polyquaternium-65, polyquaternium-66, polyquaternium-67, polyquaternium-68, polyquaternium-69, polyquaternium-70, polyquaternium-71, polyquaternium-72, polyquaternium-73, polyquaternium-74, polyquaternium-75, polyquaternium-76, polyquaternium-77, polyquaternium-78, polyquaternium-79, polyquaternium-80, polyquaternium-81, polyquaternium-82, polyquaternium-83, polyquaternium-84, polyquaternium-85, polyquaternium-86, polyquaternium-87, polyquaternium-89, polyquaternium-90, polyquaternium-91, polyquaternium-92, polyquaternium-93, polyquaternium-94, polyquaternium-95, polyquaternium-96, polyquaternium-97, polyquaternium-98, polyquaternium-99, polyquaternium-100, polyquaternium- Polyquaternium-46, polyquaternium-47, polyquaternium-49, polyquaternium-50, polyquaternium-51, polyquaternium-52, polyquaternium-53, polyquaternium-54, polyquaternium-55, polyquaternium-57, polyquaternium-61, polyquaternium-64, polyquaternium-65, polyquaternium-68, polyquaternium-92, etc. These may be used alone or in combination of two or more. Among these, polyquaternium-10 is particularly preferred.

[0029] Among the above, examples of silicone quaterniums include silicone quaternium-5, silicone quaternium-7, silicone quaternium-8, silicone quaternium-10, silicone quaternium-11, silicone quaternium-12, silicone quaternium-15, silicone quaternium-17, silicone quaternium-18, silicone quaternium-20, silicone quaternium-22, silicone quaternium-26, etc. These may be used alone or in combination of two or more.

[0030] Further, the cationic component may be a cationic surfactant (excluding the various components described separately as cationic components). Examples of the cationic surfactant include alkyl quaternary ammonium salts such as monoalkyl quaternary ammonium salts, dialkyl quaternary ammonium salts, trialkyl quaternary ammonium salts, benzalkonium quaternary ammonium salts, and monoalkyl ether quaternary ammonium salts, alkyl amine salts, fatty acid amide amine salts, ester-containing tertiary amine salts, and arcobell-type tertiary amine salts, cyclic quaternary ammonium salts such as alkyl pyridinium salts and alkyl isoquinolium salts, and benzethonium chloride. These may be used alone or in combination of two or more.

[0031] Monoalkyl-type quaternary ammonium salts include behenyltrimethylammonium chloride (behentrimonium chloride), docosyltrimethylammonium methyl sulfate (behentrimonium methosulfate), lauryltrimethylammonium chloride, lauryltrimethylammonium bromide, alkyl(16,18)trimethylammonium chloride, cetyltrimethylammonium chloride (cetrimonium chloride), cetyltrimethylammonium bromide, cetyltrimethylammonium saccharin, stearyltrimethylammonium chloride (stearyltrimonium chloride), stearyltrimethylammonium bromide, cetyltrimethylammonium saccharin, Examples of such saccharin include ammonium saccharin, stearyl trimethylammonium saccharin, distearyl dimethyl ammonium chloride (distearyl dimonium chloride), alkyl (28) trimethyl ammonium chloride, diPOE (2) oleyl methyl ammonium chloride, diPOE stearyl methyl ammonium chloride, POE (1) POP (25) diethyl methyl ammonium chloride, POP methyl diethyl ammonium chloride, methacryloyloxyethyl trimethyl ammonium chloride, dicocoyl dimethyl ammonium chloride, lanolin fatty acid aminopropyl ethyl dimethyl ammonium ethyl sulfate, behenyl trimethyl ammonium methyl sulfate, etc. These may be used alone or in combination of two or more.

[0032] As the cationic component, amino-modified silicone and cationic cellulose are preferred, and among these, amino-modified silicone is more preferred. Furthermore, when the multi-component hair cosmetic contains three or more low-viscosity cosmetic compositions, it is preferred that the low-viscosity cosmetic composition containing amino-modified silicone and the low-viscosity cosmetic composition containing cationic polymer are separately contained. When the hair cosmetic composition constituting the multi-component hair cosmetic composition includes a hair cosmetic composition containing a cationic component, the amount of the cationic component contained in the hair cosmetic composition is not limited, but the lower limit can be 0.001% by mass or more when the entire hair cosmetic composition (hair cosmetic composition containing a cationic component) is taken as 100% by mass. In this range, the effect of the cationic component can be obtained. This amount can be further 0.01% by mass or more, further 0.05% by mass or more, further 0.1% by mass or more, further 0.15% by mass or more, and further 0.2% by mass or more. On the other hand, the upper limit can be 10% by mass or less, 8% by mass or less, 6% by mass or less, 4% by mass or less, 2% by mass or less, or 1% by mass or less. In these ranges, an excellent treatment effect can be obtained when applied to hair, and the feel of the hair after treatment can be made lighter. These upper and lower limits can be appropriately combined with each other. Therefore, for example, it can be 0.001 to 10 mass%, 0.01 to 8 mass%, 0.05 to 6 mass%, 0.1 to 4 mass%, 0.15 to 2 mass%, or 0.2 to 1 mass%.

[0033] (4) Composition of multi-ingredient hair cosmetics A multi-agent hair cosmetic composition may be composed of two or more agents, and may be composed of any number of agents, for example, three or more agents. On the other hand, the upper limit of the number of agents is not limited, and may be, for example, 10 agents or less, 9 agents or less, 8 agents or less, 7 agents or less, or 6 agents or less. These upper and lower limits may be appropriately combined. Therefore, for example, it may be 2 to 10 agents, 2 to 9 agents, or 3 to 8 agents. Among these, a low-viscosity cosmetic composition may be composed of two or more agents, but it is preferable to have three or more agents from the viewpoint of making the hair feel lighter.

[0034] Of the above, when two low-viscosity cosmetic compositions are provided, it is preferable that the multi-component hair cosmetic composition is prepared so that the first low-viscosity cosmetic composition contains an anionic component and the second low-viscosity cosmetic composition contains a cationic component, as described above. If the first low-viscosity cosmetic composition is agent A and the second low-viscosity cosmetic composition is agent B, the order in which agents A and B are applied is not limited, and no significant difference in effect is likely to occur regardless of which is applied to the hair first.

[0035] In addition, when the low-viscosity cosmetic preparation includes three agents, the composition of the multi-agent hair cosmetic preparation is not limited, but may be configured, for example, so that two of the three agents contain an anionic component, and one of the three agents contains a cationic component. Also, it may be configured so that one of the three agents contains an anionic component, and two of the three agents contain a cationic component. Of these, the latter is preferred. That is, for example, it is preferable to prepare the first low-viscosity cosmetic preparation so that it contains a cationic component, the second low-viscosity cosmetic preparation so that it contains an anionic component, and the third low-viscosity cosmetic preparation so that it contains a cationic component. Furthermore, it is particularly preferable to prepare the first low-viscosity cosmetic preparation so that it contains amodimethicone as a cationic component, the second low-viscosity cosmetic preparation so that it contains hydrolyzed keratin as an anionic component, and the third low-viscosity cosmetic preparation so that it contains polyquaternium-10 as a cationic component.

[0036] In addition, assuming that the first low-viscosity cosmetic (containing a cationic component) is agent A, the second low-viscosity cosmetic (containing an anionic component) is agent B, and the third low-viscosity cosmetic (containing a cationic component) is agent C, the order in which agents A to C are applied is not limited. That is, for example, they can be applied in the order of agent A → agent B → agent C, agent A → agent C → agent B, agent B → agent A → agent C, agent B → agent C → agent A, agent C → agent A → agent B, agent C → agent B → agent A, etc., but among these, from the viewpoint of imparting an excellent treatment effect while making the feel of the hair after treatment lighter, agent A → agent B → agent C, agent C → agent B → agent A, and agent A → agent C → agent B are preferred.

[0037] The hair cosmetics constituting the multi-component hair cosmetic composition may all be low-viscosity cosmetics, or only some of them may be low-viscosity cosmetics. In other words, the multi-component hair cosmetic composition may contain not only low-viscosity cosmetics, but also non-low-viscosity cosmetics with a viscosity of more than 250 mPa s. When a non-low-viscosity cosmetic is included, the number of agents in the non-low-viscosity cosmetic may be the same as the number of agents in the low-viscosity cosmetic, or the number of agents in the non-low-viscosity cosmetic may be greater than the number of agents in the low-viscosity cosmetic, but from the viewpoint of making the hair feel lighter, it is preferable to include a greater number of agents in the low-viscosity cosmetic than in the non-low-viscosity cosmetic. That is, if the number of agents in the low-viscosity cosmetic is X1 and the number of agents in the non-low-viscosity cosmetic is X2, X1 may be equal to X2, or X1 may be greater than X2.<X2でもよいが、X1> It is preferable that X1 is X2. Furthermore, it is preferable that X2≦3, and it is more preferable that X2≦2. In this multi-component hair cosmetic composition, when the number of components of the hair cosmetic composition constituting the multi-component hair cosmetic composition is X3, X1+X2=X3 can be satisfied.

[0038] In addition, when the multi-agent hair cosmetic contains a non-low-viscosity cosmetic and X1 < X3, the order of applying the low-viscosity cosmetic and the non-low-viscosity cosmetic to the hair is not limited. However, from the perspective of lightness, it is preferable to continuously apply the low-viscosity cosmetic. That is, in the case of a multi-agent hair cosmetic composed of three types of hair cosmetics: low-viscosity cosmetic A1, low-viscosity cosmetic A2, and non-low-viscosity cosmetic B, it is more preferable to apply them in the order of A1→A2→B, A2→A1→B, B→A1→A2, or B→A2→A1 than in the order of A1→B→A2.

[0039] In addition, when continuously applying two or more low-viscosity cosmetics, the viscosity ratio of the two continuously applied low-viscosity cosmetics is not limited. However, when the viscosity of low-viscosity cosmetic A1 is X A1 (mPa·s) and the viscosity of low-viscosity cosmetic A2 is X A2 (mPa·s), the ratio of these (X A1 / X A2 ) can be 10 or less, 5 or less, and 3 or less from the perspective of lightness. On the other hand, it can be 0.1 or more, 0.3 or more, and 0.6 or more. These upper and lower limits can be appropriately combined. Therefore, for example, it can be 0.1 to 10, 0.3 to 5, and 0.6 to 3.

[0040] (5) Other components This multi-agent hair cosmetic and each hair cosmetic constituting it can contain other components within the range where the effects of the present invention can be obtained in addition to the above-described anionic components and cationic components. Examples of other components include solubilizers, oily components (excluding the above-described anionic components and the above-described cationic components), surfactants (excluding the above-described anionic components and the above-described cationic components), polymer compounds (excluding the above-described anionic components and the above-described cationic components), pH adjusters, preservatives, antioxidants, stabilizers, amino acids, plant extracts, etc. These may be used alone or in combination of two or more.

After application of the hair cosmetic composition, it may or may not be washed off. Of these, applying the next hair cosmetic composition without washing off is more preferable from the viewpoint of lightness of touch.

[0080] [2] How to use multi-ingredient hair cosmetics The method for using the multi-component hair cosmetic composition of the present invention is a method for using the multi-component hair cosmetic composition described in the above [1], characterized in that it includes a low-viscosity cosmetic composition application step of continuously applying the low-viscosity cosmetic composition to hair.

[0081] As mentioned above, the multi-component hair cosmetic contains at least two types of low-viscosity cosmetic. These low-viscosity cosmetic compositions may be applied to the hair in any order, but the method of use includes a step of successively applying the low-viscosity cosmetic compositions to the hair (a step of applying a low-viscosity cosmetic). This method of use has the effect of imparting an excellent treatment effect while making the feel of the hair after treatment lighter than before.

[0082] For example, when the multi-component hair cosmetic is composed only of a low-viscosity cosmetic, the method of use necessarily includes a low-viscosity cosmetic application step. On the other hand, when the multi-component hair cosmetic contains a non-low-viscosity cosmetic, for example, if the first low-viscosity cosmetic is agent A, the second low-viscosity cosmetic is agent B, and the non-low-viscosity cosmetic is agent D, it is possible to select the application order of agent A → agent D → agent B. However, in the method of use, by selecting either the application order of agent A → agent B → agent D or agent B → agent A → agent D, it is possible to impart an excellent treatment effect while making the feel of the hair after treatment lighter than before. The same applies when the multi-component hair cosmetic contains two or more non-low-viscosity cosmetic agents.

[0083] Furthermore, when two low-viscosity cosmetic compositions are provided, as described above, the multi-component hair cosmetic composition can be prepared so that the first low-viscosity cosmetic composition contains an anionic component and the second low-viscosity cosmetic composition contains a cationic component. If the first low-viscosity cosmetic composition is agent A and the second low-viscosity cosmetic composition is agent B, the order in which agents A and B are applied is not limited and either may be applied to the hair first, but since damaged hair is usually anionic, it is preferable to apply agent B, which contains a cationic component, before agent A.

[0084] Furthermore, when the low-viscosity cosmetic preparation includes three agents, the composition of the multi-agent hair cosmetic preparation is not limited, but for example, two of the three agents may be configured to contain an anionic component, and one of the three agents may be configured to contain a cationic component. Alternatively, one of the three agents may be configured to contain an anionic component, and two of the three agents may be configured to contain a cationic component. Of these, the latter is preferred. That is, for example, it is preferred to prepare the first low-viscosity cosmetic preparation to contain a cationic component, the second low-viscosity cosmetic preparation to contain an anionic component, and the third low-viscosity cosmetic preparation to contain a cationic component.

[0085] Among these, assuming that the first low-viscosity cosmetic (containing a cationic component) is agent A, the second low-viscosity cosmetic (containing an anionic component) is agent B, and the third low-viscosity cosmetic (containing a cationic component) is agent C, there is no restriction on the order in which agents A to C are applied. That is, for example, they can be applied in the order of agent A → agent B → agent C, agent A → agent C → agent B, agent B → agent A → agent C, agent B → agent C → agent A, agent C → agent A → agent B, agent C → agent B → agent A, etc., but among these, from the viewpoint of imparting an excellent treatment effect while making the hair feel lighter after treatment, agent A → agent B → agent C, agent C → agent B → agent A, and agent A → agent C → agent B are preferred.

[0086] The method of application of the multi-component hair cosmetic composition is not limited, and each of the first and second components can be applied to the hair using a tool such as a comb, brush, or spatula. Furthermore, the composition can be applied to the hair using the user's hands. Furthermore, the composition can be applied by spraying the composition onto the hair as a mist, aerosol, foam, or the like. In addition, the composition can be applied by impregnation (dipping), coating, penetration, or other procedures. These may be used alone or in combination of two or more. Furthermore, the multi-component hair cosmetic composition may be applied to hair wet with water or warm water, or to dry hair.

[0087] In addition, after applying a hair cosmetic to the hair, the hair cosmetic may be washed off and the next hair cosmetic may be applied, or after applying a hair cosmetic to the hair, the next hair cosmetic may be applied over the first hair cosmetic without washing off the first hair cosmetic. Of these, applying the next hair cosmetic without washing off is more preferable from the viewpoint of lightness of touch. Furthermore, after applying all the hair cosmetics constituting the multi-component hair cosmetic, they may or may not be washed off. EXAMPLES

[0100] [2] Use of multi-ingredient hair care products (1) (1) Preparation of damaged hair bundle A 10 cm long bundle of untreated black hair (manufactured by Beaulax) was prepared, and this bundle was treated twice with a bleaching agent and a perm agent to obtain a damaged bundle. (2) Application The hair cosmetics of the above-mentioned agents A to E were applied in the application order shown in Table 6. Specifically, the hair cosmetics were applied to 1 g of damaged hair bundle so that the application amount of each hair cosmetic was 0.04 g. That is, in Examples 7 to 12 and Comparative Examples 4 to 5, the first agent was applied, and then the second agent was applied without washing off the applied hair cosmetics. In addition, in Examples 1 to 6, Examples 13 to 14, and Comparative Examples 1 to 3, the first agent was applied, and then the applied hair cosmetics were not washed off, the second agent was applied, and then the applied hair cosmetics were not washed off, and then the third agent was applied. Furthermore, in Example 15, the first agent was applied, and then the applied hair cosmetics were not washed off, the second agent was applied, and then the applied hair cosmetics were not washed off, and then the third agent was applied, and then the applied hair cosmetics were not washed off, and then the fourth agent was applied. In addition, in Example 16, the first agent was applied, and then the applied hair cosmetic was not washed off, the second agent was applied, and then the applied hair cosmetic was not washed off, and the third agent was applied. After that, the hair was washed once 10 times using 100g of purified water, and then the fourth agent and the fifth agent were applied over each other. After finishing the application of all the hair cosmetics shown in each example of Table 6, the damaged hair bundle was washed 10 times using 100g of purified water each. Then, the hair bundle was dried using a hair dryer to obtain the evaluation hair bundles of Examples 1 to 16 and Comparative Examples 1 to 5.

[0101] [Table 6]

[0102] (3) Evaluation (3-1) Evaluation of lightness The evaluation hair bundles of Examples 1 to 16 and Comparative Examples 1 to 5 obtained in [2](2) above were evaluated as follows. That is, the hair bundles were evaluated by five expert panelists for their lightness without stickiness. The evaluation was performed using the following five-level scale. Specifically, each panelist selected the score that most closely matched their own feel, and the arithmetic mean of the scores selected by the five panelists was calculated. The arithmetic mean was rounded off to one decimal place and shown in the "lightness" column of Table 6. "5": Non-sticky and very light "4": Light and almost non-sticky "3": Less sticky and slightly light "2": Slightly sticky and heavy "1": Sticky and very heavy

After that, washing was performed once using 100 g of purified water 10 times, and then agent E was applied. After finishing the application of all the hair cosmetics, the damaged hair bundle was washed 10 times using 100 g of purified water each. Then, the hair bundle was dried using a hair dryer to obtain the evaluation hair bundles of Examples 17 to 27.

[0108] [Table 7]

[0109] (2) Evaluation (2-1) Evaluation of lightness The evaluation hair bundles of Examples 17 to 27 obtained in [4](1) above were evaluated as follows. That is, the hair bundles were evaluated by five expert panelists for their lightness without stickiness. The evaluation was performed using the following five-level scale. Specifically, each panelist selected the score that most closely matched their own feel, and the arithmetic mean of the scores selected by the five panelists was calculated. The arithmetic mean was rounded off to one decimal place and shown in the "lightness" column of Table 7. "5": Very non-sticky and light "4": Light and not sticky "3": Somewhat light "2": Slightly sticky and heavy "1": Very sticky and heavy

[0110] (2-2) Evaluation of cohesion The evaluation hair bundles of Examples 17 to 27 obtained in [4](1) above were evaluated as follows. That is, five expert panelists evaluated the manageability of the hair. The evaluation was performed using the following five-level scale. Specifically, each panelist selected the score that most closely matched their own feel, and the arithmetic mean of the scores selected by the five panelists was calculated. The arithmetic mean was rounded off to one decimal place and shown in the "Manageability" column of Table 7.

[0111] [5] Effects of the embodiment Comparative Examples 4 to 5 in Table 6 are examples in which a low-viscosity cosmetic and a cream-type non-low-viscosity cosmetic are applied in layers. In contrast, Comparative Examples 1 to 3 are examples in which a low-viscosity cosmetic is applied, and then two types of cream-type non-low-viscosity cosmetic are applied in layers. As described above, it can be seen that applying a cream-type hair cosmetic in layers improves the manageability of hair. On the other hand, there is a problem in that the feel of hair becomes sticky and heavy. In contrast, in Examples 1 to 16, low-viscosity cosmetics are applied in layers. As a result, it can be seen that the evaluation of lightness is dramatically improved in all of the examples. On the other hand, in all of Examples 1 to 16, the evaluation of manageability is maintained at 3 or more, and it can be seen that the hair can be given a sense of manageability to the ends of the hair while having lightness without becoming too heavy. Among these, in the cases of Examples 1 to 6 in which the three-component low-viscosity cosmetic composition was applied in layers, it was possible to provide an excellent feeling of lightness while maintaining a manageability rating of 4 or higher, and to impart an excellent manageability feeling all the way to the ends of the hair, and it was found that Example 1 in particular provided an excellent effect.

[0112] Furthermore, as described above, in the cases of Comparative Examples 1 to 5 where the low-viscosity cosmetic is not applied multiple times, there is a problem that the cosmetic becomes heavy. In contrast, in the cases of Examples 15 to 16 where the low-viscosity cosmetic is applied multiple times, the evaluation of lightness can be improved dramatically. In addition, in Example 16, even if non-low-viscosity cosmetic D and E are used after the low-viscosity cosmetic is applied multiple times, the cosmetic does not become heavy and lightness is maintained. In addition, in Example 7, excellent lightness is obtained by applying Agent A → Agent B multiple times, but there is room for further improvement in the cohesiveness. In addition, in Example 13, excellent cohesiveness is obtained by applying Agent A → Agent B → Agent D multiple times, but there is room for further improvement in the lightness. In contrast, in the cases of Examples 15 to 16 where Agent D and Agent E are applied while applying Agent A → Agent B → Agent C multiple times, excellent lightness and excellent cohesiveness can be achieved at the same time. In this way, it can be seen that when a low-viscosity cosmetic is applied in the order of cationic component → anionic component → cationic component, it is possible to achieve both lightness and manageability at a high level. This is thought to be because the anionic component, particularly keratin or its hydrolysate, is blended in the low-viscosity cosmetic, and therefore the effect of the anionic component is superior to that when it is blended in a non-low-viscosity cosmetic.
