Description

[Technical field]

[0001] The present invention relates to a hair treatment set and a hair treatment composition. More specifically, the present invention relates to a hair treatment set and a hair treatment composition suitable for reducing hair frizz. [Background technology]

[0002] Hair is damaged on a daily basis by washing with a detergent such as shampoo and drying with a hair dryer. In addition, in recent years, due to the diversification of hairstyles, it has become common to subject hair to chemical treatments such as dyeing, bleaching, and perming. These chemical treatments also damage hair. Furthermore, it is known that the texture of hair changes with age.

[0003] Hair becomes wavy due to damage caused by chemical treatments such as dyeing and bleaching, damage caused by physical treatments such as heat and friction, and changes in hair texture due to aging. As the amount of wavy hair increases, the hair becomes dry and spreads out. In addition, as the amount of wavy hair increases, the hair texture, such as the overall luster, feel, and manageability, deteriorates.

[0004] In order to address the above-mentioned problems, hair treatments containing specific compounds have been proposed. For example, Patent Document 1 describes that hair frizz is improved by hardening the hair using a hair treatment composition containing an aspartame component.

[0005] Patent Document 2 describes that hair frizz can be improved by using a hair cosmetic composition that combines a first agent containing a specific cationic polymer with a second agent containing a specific phosphorylcholine group-containing polymer. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] JP 2013-103882 A [Patent Document 2] JP 2017-190290 A Summary of the Invention [Problem to be solved by the invention]

[0007] The techniques described in Patent Documents 1 and 2 apply a hair treatment agent to the surface of the hair to harden the hair in order to suppress hair wavyness. The hair compositions described in Patent Documents 1 and 2 tend to harden the hair. In addition, the effect of the hair treatment agent attached to the surface of the hair is short-lived.

[0008] An object of the present invention is to provide a hair treatment set and a hair treatment composition suitable for reducing hair frizz. [Means for solving the problem]

[0009] The present invention relates to A composition A containing an anionic acrylic polymer, an anionic surfactant, and a hydrolyzed protein or a derivative thereof; and composition B comprising a cationic surfactant; To provide a hair treatment set.

[0010] According to another aspect of the present invention, The composition includes an anionic acrylic polymer, an anionic surfactant, and a hydrolyzed protein or a derivative thereof. A hair treatment composition is provided. Effect of the Invention

[0011] The hair treatment set and hair treatment composition according to the present invention are suitable for reducing hair frizz. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] Hereinafter, embodiments of the present invention will be described, but the present invention is not limited to the following embodiments.

[0013] (Composition A) Composition A according to this embodiment includes an anionic acrylic polymer. The anionic acrylic polymer may be an anionic polymer or a salt thereof that includes at least one monomer selected from the group consisting of acrylic acid, methacrylic acid, alkyl acrylate, alkyl methacrylate, hydroxyalkyl acrylate, and hydroxyalkyl methacrylate. The anionic acrylic polymer may have a structure in which polymers that include at least one monomer selected from the group consisting of acrylic acid, methacrylic acid, alkyl acrylate, alkyl methacrylate, hydroxyalkyl acrylate, and hydroxyalkyl methacrylate are crosslinked with each other.

[0014] The anionic acrylic polymer may have an anionic functional group. Examples of the anionic functional group are a carboxy group, a phosphoric acid group, and a sulfonic acid group.

[0015] The number of carbon atoms in the alkyl group contained in the alkyl acrylate, alkyl methacrylate, hydroxyalkyl acrylate, or hydroxyalkyl methacrylate is not limited to a specific value and may be 10 or more and 30 or less. The alkyl group may be linear or branched. The alkyl group may be a saturated or unsaturated hydrocarbon group.

[0016] Examples of anionic acrylic polymers are acrylates / alkyl acrylate (C10-30) crosspolymer, hydroxyethyl acrylate / sodium acryloyldimethyltaurate copolymer, carbomer, acrylates copolymer, sodium polyacrylate, and sodium alkyl acrylate copolymer. The acrylates / alkyl acrylate (C10-30) crosspolymer refers to a polymer in which a copolymer of acrylic acid or methacrylic acid and an alkyl acrylate is crosslinked with an ether such as an allyl ether of sucrose or an allyl ether of pentaerythritol. The alkyl acrylate (C10-30) refers to an ester of acrylic acid and an alkyl group having 10 to 30 carbon atoms. The acrylates copolymer refers to a copolymer composed of at least two monomers selected from the group consisting of alkyl acrylate (C1-4), alkyl methacrylate (C1-4), acrylic acid, and methacrylic acid. As the anionic acrylic polymer, only one selected from these anionic acrylic polymers may be used, or two or more of them may be used in combination.

[0017] The content of the anionic acrylic polymer relative to the total mass of composition A is not limited to a specific value, and may be 0.001 mass % to 2.0 mass %, 0.005 mass % to 1.5 mass %, or even 0.01 mass % to 1.0 mass %.

[0018] Composition A contains an anionic surfactant. By containing an anionic surfactant, the hydrolyzed protein described later can be easily penetrated into the inside of the hair. Examples of anionic surfactants are polyoxyalkylene alkyl ether phosphate, N-acyl glutamic acid, alkyl sulfate, and derivatives thereof. A preferred example of polyoxyalkylene alkyl ether phosphate is polyoxyethylene alkyl ether phosphate. The number of carbon atoms of the alkyl group contained in the polyoxyethylene alkyl ether phosphate is not limited to a specific value, and may be 12 to 22, 14 to 20, or even 16 to 20. Examples of polyoxyethylene alkyl ether phosphate are polyoxyethylene lauryl ether phosphate, polyoxyethylene cetyl ether phosphate, polyoxyethylene stearyl ether phosphate, polyoxyethylene cetearyl ether phosphate, and salts thereof. Examples of polyoxyethylene lauryl ether phosphate are laureth-2 phosphate, laureth-4 phosphate, dilaureth-10 phosphate, and trilaureth-4 phosphate. Examples of polyoxyethylene cetyl ether phosphate are ceteth-10 phosphate and ceteth-20 phosphate. Examples of polyoxyethylene stearyl ether phosphate are steareth-2 phosphate and steareth-3 phosphate. Examples of polyoxyethylene cetearyl ether phosphate are triceteareth-4 phosphate. Examples of N-acyl glutamic acid and its salts are sodium N-lauroyl glutamate, sodium N-stearoyl glutamate, arginine N-stearoyl glutamate, and sodium N-myristoyl glutamate. Examples of alkyl sulfates are sodium lauryl sulfate and sodium cetyl sulfate. Only one selected from these anionic surfactants may be used, or two or more may be used in combination.

[0019] A preferred example of the anionic surfactant is polyoxyethylene alkyl ether phosphate having an alkyl group with 12 to 22 carbon atoms. By using polyoxyethylene alkyl ether phosphate having an alkyl group with 12 to 22 carbon atoms as the anionic surfactant, it becomes easier to ensure that the hydrolyzed protein described below penetrates into the hair. As a result, in addition to the effect of improving hair frizz, it is possible to more reliably improve the texture of the hair, such as shine and ease of running fingers through it.

[0020] The content of the anionic surfactant relative to the total mass of composition A is not limited to a specific value, and may be 0.005 mass % to 8.0 mass %, 0.01 mass % to 6.0 mass %, or even 0.05 mass % to 4.0 mass %.

[0021] Composition A contains a hydrolyzed protein or a derivative thereof. The hydrolyzed protein or a derivative thereof easily penetrates into the inside of the hair, so that it is possible to improve wavy hair from the inside of the hair. In addition, the inclusion of a hydrolyzed protein or a derivative thereof in composition A can improve the texture of the hair. Furthermore, the inclusion of a hydrolyzed protein or a derivative thereof and an anionic surfactant in composition A makes it easier for the hydrolyzed protein to penetrate more reliably into the inside of the hair. In this way, the inclusion of a hydrolyzed protein or a derivative thereof in composition A provides an improvement effect against hair wavyness and also tends to improve the texture of the hair.

[0022] Hydrolyzed protein is a peptide compound obtained by hydrolyzing protein. Hydrolyzed protein is, for example, a hydrolyzate (PPT) of naturally derived protein. Examples of hydrolyzed protein are hydrolyzed keratin, hydrolyzed silk, hydrolyzed almond protein, hydrolyzed casein, hydrolyzed oat protein, hydrolyzed yeast protein, hydrolyzed collagen, hydrolyzed conchiolin, hydrolyzed lupin protein, hydrolyzed soybean protein, hydrolyzed pea protein, hydrolyzed corn protein, hydrolyzed milk protein, hydrolyzed honey protein, hydrolyzed hazelnut protein, hydrolyzed jojoba protein, hydrolyzed vegetable protein, hydrolyzed royal jelly protein, hydrolyzed wheat protein, and hydrolyzed rice protein. Only one selected from these hydrolyzed proteins may be used, or two or more may be used in combination.

[0023] A preferred example of the hydrolyzed protein is hydrolyzed keratin. Hydrolyzed keratin is more likely to penetrate into the inside of hair. As a result, it is possible to more reliably obtain an improvement effect against hair frizz.

[0024] The hydrolyzed protein derivative means a protein that has been chemically modified by silylation, acylation, cationization, etc. Examples of silylated hydrolyzed proteins are (dihydroxymethylsilylpropoxy) hydroxypropyl hydrolyzed silk, (dihydroxymethylsilylpropoxy) hydroxypropyl hydrolyzed soy protein, (dihydroxymethylsilylpropoxy) hydroxypropyl hydrolyzed wheat protein, (dihydroxymethylsilylpropoxy) hydroxypropyl hydrolyzed collagen, hydrolyzed sesame protein PG propyl methylsilanediol, and (dihydroxymethylsilylpropoxy) hydroxypropyl hydrolyzed keratin. Examples of acylated hydrolyzed proteins are lauroyl hydrolyzed silk, isostearoyl hydrolyzed silk, cocoyl hydrolyzed soy protein, palmitoyl hydrolyzed wheat protein, cocoyl hydrolyzed collagen, undecylenoyl hydrolyzed collagen, isostearoyl hydrolyzed collagen, and rosin hydrolyzed collagen. Examples of cationic hydrolyzed proteins are hydroxypropyltrimonium hydrolyzed silk, cocodimonium hydroxypropyl hydrolyzed silk, hydroxypropyltrimonium hydrolyzed wheat protein, cocodimonium hydroxypropyl hydrolyzed wheat protein, hydroxypropyltrimonium hydrolyzed collagen, cocodimonium hydroxypropyl hydrolyzed collagen, hydroxypropyltrimonium hydrolyzed casein, cationic hydrolyzed conchiolin, and hydroxypropyltrimonium hydrolyzed keratin. Only one selected from these hydrolyzed protein derivatives may be used, or two or more may be used in combination.

[0025] The weight-average molecular weight of the hydrolyzed protein is not limited to a specific value, and may be 100 or more, more preferably 1000 or more, and particularly 10000 or more. The upper limit of the weight-average molecular weight of the hydrolyzed protein is not limited to a specific value, and may be 100000, 80000, or even 50000. When the hydrolyzed protein has an appropriate weight-average molecular weight, the effect of improving hair frizz becomes significant.

[0026] The content of hydrolyzed protein relative to the total mass of composition A is not limited to a specific value, and may be 0.005% by mass to 8.0% by mass, 0.01% by mass to 6.0% by mass, or even 0.05% by mass to 4.0% by mass.

[0027] Composition A may further contain a higher alcohol. By containing a higher alcohol, composition A having creamy properties can be obtained, and the texture of hair can be improved more reliably.

[0028] The number of carbon atoms of the higher alcohol is not particularly limited, and may be 8 to 30, or 14 to 22. The higher alcohol may be a saturated alcohol or an unsaturated alcohol. Examples of the higher alcohol include lauryl alcohol, myristyl alcohol, cetyl alcohol, stearyl alcohol, cetearyl alcohol, oleyl alcohol, and behenyl alcohol. Only one selected from these higher alcohols may be used, or two or more may be used in combination.

[0029] The content of the higher alcohol relative to the total mass of composition A is not limited to a specific value, and may be 0.01 mass % to 10.0 mass %, 0.05 mass % to 7.5 mass %, or even 0.1 mass % to 5.0 mass %.

[0030] Composition A is, for example, weakly acidic to weakly alkaline. The pH of composition A at 25°C may be, for example, 5.0 or more, 5.5 or more, or even 6.0 or more, and may be 8.0 or less, or even 7.5 or less. When composition A has an appropriate pH, the anionic acrylic polymer contained in composition A can have excellent stability. In addition, when composition A has an appropriate pH, hair is less likely to be damaged, and the texture of hair can be more reliably improved.

[0031] A pH adjuster typically used in hair treatments can be used as the pH adjuster for adjusting the pH of Composition A. Examples of pH adjusters include phosphoric acid, lactic acid, guanidine carbonate, sodium dihydrogen phosphate, trisodium phosphate, sesquicarbonate, arginine, sodium bicarbonate, sodium carbonate, monoethanolamine, ammonia, 2-amino-2-methyl-1-propanol, sodium hydroxide, tripotassium citrate, trisodium citrate, and diammonium hydrogen phosphate.

[0032] The formulation of the composition A is not limited to a specific formulation, and any known formulation can be used.Preferable formulations are gel, solution, cream, or emulsion, and more preferable formulation is cream.When the composition A is cream, it is easier to obtain the effect of improving the frizziness more reliably, and the texture of the hair can be improved more reliably.

[0033] As described above, the composition A includes an anionic acrylic polymer, an anionic surfactant, and a hydrolyzed protein. The ratio of the contents of each component contained in the composition A is not limited to a specific value. In the composition A, the ratio of the content of the hydrolyzed protein to the content of the anionic surfactant may be 0.05 to 20, or even 0.1 to 10, on a mass basis. In the composition A, the ratio of the content of the anionic acrylic polymer to the content of the anionic surfactant may be 0.01 to 10, or even 0.05 to 5, on a mass basis. In the composition A, the ratio of the content of the anionic acrylic polymer to the content of the hydrolyzed protein may be 0.01 to 10, or even 0.05 to 5, on a mass basis.

[0034] (Composition B) Composition B according to this embodiment contains a cationic surfactant. By containing a cationic surfactant, hair can be softened, so that hair frizz can be improved more reliably. In addition, by containing a cationic surfactant, hair texture can be improved more reliably.

[0035] The cationic surfactant is not limited to a specific type, so long as it is a cationic surfactant that is normally used in hair cosmetics. Examples of the cationic surfactant are alkyl quaternary ammonium salts, alkenyl quaternary ammonium salts, alkylamine salts, and fatty acid amide amine salts. Examples of the alkyl quaternary ammonium salts are cetrimonium chloride, cetrimonium bromide, steartrimonium chloride, steartrimonium bromide, behenyltrimonium chloride, behenyltrimonium bromide, stearalkonium chloride, benzalkonium chloride, stearoxypropyltrimonium chloride, distearyldimonium chloride, distearyldimonium bromide, dibehenyldimonium chloride, dibehenyldimonium bromide, dicetyldimonium chloride ...

[0036] Only one selected from these cationic surfactants may be used, or two or more of them may be used in combination.

[0037] The content of the cationic surfactant relative to the total mass of composition B is not limited to a specific value, and may be 0.01 mass % to 10.0 mass %, 0.05 mass % to 7.5 mass %, or even 0.1 mass % to 5.0 mass %.

[0038] Composition B may further contain a higher alcohol. By containing a higher alcohol, a composition B having a creamy property can be obtained, and the texture of the hair can be improved more reliably. The higher alcohol may be any of those described above.

[0039] The content of the higher alcohol relative to the total mass of composition B is not limited to a specific value, and may be 0.01 mass % to 15.0 mass %, 0.1 mass % to 10.0 mass %, or even 0.5 mass % to 7.5 mass %.

[0040] Composition B may further contain silicone. By containing silicone, the feel of hair can be further improved.

[0041] Examples of silicones include dimethicone, dimethiconol, and amino-modified silicones. Only one of these silicones may be used, or two or more of them may be used in combination.

[0042] Amino-modified silicones are silicones that have a structure in which amino groups are bonded directly or via a substituent to the silicone backbone. Examples of amino-modified silicones are aminopropylmethylsiloxane-dimethylsiloxane copolymer (aminopropyl dimethicone), aminoethylaminopropylsiloxane-dimethylsiloxane copolymer (amodimethicone), and aminoethylaminopropylmethylsiloxane-dimethylsiloxane copolymer (trimethylsilylamodimethicone).

[0043] A preferred example of the silicone is amino-modified silicone, which has a cationic functional group as described above and can more reliably improve the texture of hair.

[0044] The content of silicone relative to the total mass of composition B is not limited to a specific value, and may be 0.01 mass % to 15.0 mass %, 0.1 mass % to 10.0 mass %, or even 0.5 mass % to 5.0 mass %.

[0045] Composition B may further contain a polyhydric alcohol. The polyhydric alcohol can further improve the moisturizing feeling of hair. The polyhydric alcohol means a compound having two or more hydroxyl groups in one molecule.

[0046] Examples of polyhydric alcohols include ethylene glycol, propylene glycol, 1,3-butylene glycol, 1,4-butanediol, 1,2-pentanediol, 1,2-hexanediol, 1,6-hexanediol, neopentyl glycol, 1,8-octanediol, 1,10-decanediol, diethylene glycol, spiroglycol, propylene glycol, dipropylene glycol, glycerin, and diglycerin.

[0048] Composition B is, for example, weakly acidic. The pH of composition B at 25°C may be, for example, 4.0 or more, or 4.5 or more, or 6.0 or less, or 5.5 or less. When composition B has an appropriate pH, the cationic surfactant contained in composition B may have excellent stability.

[0049] A pH adjuster that is generally used in hair treatments can be used as the pH adjuster for adjusting the pH of composition B. The pH adjusters described above for composition A can be used.

[0050] The dosage form of composition B is not limited to a specific dosage form, and a known dosage form can be adopted. The dosage form of composition B may be the same as or different from the dosage form of composition A. The preferred dosage form is a gel, a solution, a cream, or an emulsion, and the more preferred dosage form is a cream. When composition B is a cream, it is easier to reliably obtain the improvement effect against hair frizz.

[0051] (Other Ingredients) Compositions A and B may contain any component other than the above-mentioned components. The optional component may be a component contained in a known hair treatment agent.

[0052] An example of an optional component is a cationic polymer. A cationic polymer means, for example, a polymer having a cationic functional group, such as a quaternary ammonium group, in the molecule. A cationic polymer can typically be a polymer containing an amino group or a quaternary ammonium group in a side chain of a polymer chain.

Examples of the nonionic surfactant are polyoxyethylene alkyl ether, polyoxyethylene sorbitan fatty acid ester, sorbitan fatty acid ester, polyoxyethylene hydrogenated castor oil, alkyl glucoside, glyceryl stearate, and coconut oil fatty acid diethanolamide.

[0054] As described above, composition A contains an anionic surfactant and hydrolyzed protein. This makes it possible to repair damage inside the hair. Furthermore, the cationic surfactant contained in composition B acts to fix the hydrolyzed protein inside the hair. As a result, these components are less likely to flow out of the hair. Hair treated with a hair treatment set containing hydrolyzed protein has an excellent effect of improving hair frizz, and the effect is also excellent in durability.

[0055] In addition, composition A contains an anionic acrylic polymer. Therefore, by applying the anionic acrylic polymer to hair, damage to the surface of the hair can be repaired. This improves the texture of the hair. The hair treatment set according to this embodiment makes it possible to repair the inside and surface of the hair. This makes the improvement effect against hair frizz more pronounced, and also improves the texture of the hair. As far as the present inventors know, a hair treatment that repairs not only the surface of hair but also the inside of hair to improve hair frizz has not been known so far.

[0056] Next, a method for treating hair with the hair treatment set will be described.

[0058] In the treatment method using the hair treatment agent set according to this embodiment, a step of removing the hair treatment agent may be included between hair treatment with composition A and hair treatment with composition B, or composition A may be contacted with the hair and then composition B may be contacted with the hair without removing composition A. After contacting composition B with the hair, a step of removing composition B may be included, or a step of removing composition B may not be included. Composition A or B can be removed, for example, by rinsing with water or by washing the hair with a detergent such as shampoo.

[0059] In the treatment method using the hair treatment agent set according to this embodiment, the order of hair treatment with composition A and hair treatment with composition B is not limited to a particular order. Hair treated with composition A may be treated with composition B, and hair treated with composition B may be treated with composition A. The number of times hair treatment is performed with compositions A and B is also not limited to a particular number of times. Compositions A and B may be applied alternately to the hair. EXAMPLES

[0060] The present invention will be described below based on examples. Note that the present invention is not limited to these examples, and these examples can be modified or changed based on the spirit of the present invention, and they are not excluded from the scope of the present invention.

[0061] <Preparation of Composition A> Creamy compositions A according to Examples 1 to 9 and Comparative Examples 1 to 16 were prepared, containing anionic acrylic polymers, anionic surfactants, hydrolyzed proteins, and cetearyl alcohol in the amounts shown in Tables 1 to 4 below. Then, arginine was added to the creamy composition A to adjust the pH of the composition A at 25°C to 7.0. All units in the tables are mass %. The notation "-" in the "ingredients" column in each table means that the ingredient is not contained. The (acrylates / alkyl acrylate (C10-30)) crosspolymer used was PEMULEN TR-2 manufactured by Lubrizol Advanced Materials, Inc. The (hydroxyethyl acrylate / sodium acryloyldimethyltaurate) copolymer used was SIMULGEL NS manufactured by SEPPIC.

[0062] <Preparation of Composition B> Creamy compositions B according to Examples 1 to 9 and Comparative Examples 1 to 16 were prepared containing cationic surfactant, glyceryl stearate, stearyl-10 phosphate, polyquaternium-10, or polyquaternium-37, cetearyl alcohol, and glycerin in the amounts shown in Tables 1 to 4 below. Lactic acid was then added to the creamy composition B to adjust the pH of the composition B at 25° C. to 4.5. All units in the tables are mass %.

[0063] <Evaluation> The prepared hair bundle for evaluation was washed with warm water, thoroughly moistened, and then the prepared composition A (1 g) according to the examples and comparative examples was applied uniformly to the hair bundle. Subsequently, the prepared composition B (1 g) according to the examples and comparative examples was applied uniformly to the hair bundle. The hair bundle was washed with warm water to wash off the composition, and after towel drying, the hair bundle was dried with a hair dryer. The dried hair bundle was subjected to a sensory evaluation by 10 beauty professionals for "improvement of waviness," "luster," "ease of fingering," and "goodness of fit." The evaluation was made on a 5-point scale of "good: 5 points, slightly good: 4 points, normal: 3 points, slightly bad: 2 points, bad: 1 point," and was judged based on the following criteria using the average score of the 10 beauty professionals. The results are shown in Tables 1 to 4. ◎: Very good: Average score is 4.5 or higher ○: Excellent: Average value is 3.5 points or more and less than 4.5 points △: Poor: Average score is between 1.5 and 3.5 points ×: Very poor: Average score is less than 1.5 points

[0064] [Table 1]

[0066] [Table 3]

[0067] [Table 4]

[0068] In each example, an improvement effect was obtained against hair wavyness. In addition, in each example, good results were obtained with respect to hair texture. In particular, by containing hydrolyzed protein in composition A, the improvement effect against hair wavyness became remarkable, and the hair texture was also improved. On the other hand, in each comparative example, hair wavyness could not be sufficiently improved. In addition, in each comparative example, hair texture could not be improved.
