Description

[Technical Field]

[0001] The present invention relates to a hair treatment agent. [Background technology]

[0002] Hair rinses and hair treatments have been used for some time to impart smoothness, suppleness, manageability, etc. Hair rinses and hair treatments generally contain conditioning ingredients such as cationic surfactants, oils, silicone derivatives, and protein hydrolysates, and these ingredients are adsorbed onto the hair surface to exert their conditioning effects.

[0003] However, conventional hair rinses and hair treatments have a weak conditioning effect on hair that has been repeatedly colored or permed, and the conditioning effect is easily lost when shampooed.

[0004] As a technique for improving the conditioning effect on hair that has been treated with hair coloring, perms, or the like, and for increasing the durability of the conditioning effect, a technique for forming an ionic complex on the hair by combining an anionic substance (polymer, protein hydrolysate, etc.) with a cationic substance (polymer, surfactant, etc.) has been proposed (e.g., Patent Documents 1 to 5). However, even with these techniques, the conditioning effect is insufficient for severely damaged hair or severely damaged hair ends. [Prior art documents] [Patent documents]

[0015] The hair treatment agent of the present invention can impart excellent hair smoothness, suppleness, and manageability (hereinafter referred to as conditioning effect) to severely damaged hair that has been subjected to multiple chemical treatments such as bleaching, hair coloring, and perming (hereinafter referred to as bleaching, etc.). DETAILED DESCRIPTION OF THE INVENTION

[0016] The hair to which the hair treatment agent of the present invention is applied is preferably hair that has been subjected to a bleaching treatment or the like, more preferably hair that has been subjected to two or three bleaching treatments or the like, and even more preferably hair that has been subjected to four or more bleaching treatments or the like. Hair that has been repeatedly bleached, such as with white bleach, is more severely damaged than hair that has been dyed with a conventional hair color or permed, and therefore conventional hair treatments have not been able to provide sufficient conditioning effects on such severely damaged hair.

[0017] The hair treatment agent of the present invention contains (A1) polyquaternium-64 and (B1) bisethoxydiglycol dicarboxylate as essential ingredients. The inclusion of both components provides excellent conditioning effects to severely damaged hair, i.e., imparts smoothness, suppleness, and manageability to the hair. Furthermore, the use of treatment agent Z prolongs the duration of the conditioning effects imparted by the hair treatment agent of the present invention, i.e., the conditioning effects can be maintained even after multiple shampooings of the hair following treatment with the hair treatment agent.

[0018] The hair treatment agent of the present invention will now be described. The hair treatment agent of the present invention contains treatment agent X or treatment agent Y described below. Treatment agent X: (A1) Polyquaternium-64 and (B1) bisethoxydiglycol dicarboxylate are contained in the same container A (sometimes referred to as a one-component treatment agent). Treatment agent Y: This treatment agent is composed of a first agent and a second agent, where the first agent contains (A1) polyquaternium-64 in container B, and the second agent contains (B1) bisethoxydiglycol dicarboxylate in container C. The first agent and the second agent are contained in different containers (sometimes referred to as a two-agent treatment agent). The conditioning effect of the present invention can be obtained if (A1) polyquaternium-64 and (B1) bisethoxydiglycol dicarboxylate are simultaneously applied to the hair during hair treatment. Therefore, before application, (A1) polyquaternium-64 and (B1) bisethoxydiglycol dicarboxylate may be stored together in the same container A (single-component treatment agent), or they may be stored separately in separate containers B and C to prevent mixing (two-component treatment agent).

[0019] (A1) Polyquaternium-64 (A1) Polyquaternium-64 is a polymer having a phosphorylcholine group represented by the following formula (I). [ka]

[0020] There are several types of polyoctanium, but as a result of the investigations conducted by the present inventors, only the combination of polyoctanium-64 and bisethoxydiglycol dicarboxylate exhibits an excellent hair conditioning effect on severely damaged hair. In the present invention, various commercially available polyquaternium-64s such as "LIPIDURE-C" (manufactured by NOF Corporation) can be used.

[0021] Increasing the content of (A1) polyoctanium-64 contributes to improving the conditioning effect, particularly the smoothness of hair. On the other hand, if the content of (A1) polyoctanium-64 is too high, the hair becomes too soft and prone to tangling, and the conditioning effect, i.e., the smoothness, suppleness, and manageability of hair, tends to deteriorate. The content of (A1) Polyquaternium-64 in Treatment Agent X or the first agent is preferably 0.0005% by mass or more, more preferably 0.0025% by mass or more, even more preferably 0.005% by mass or more, and is preferably 1% by mass or less, more preferably 0.5% by mass or less, even more preferably 0.2% by mass or less.

[0022] (B1) Bisethoxydiglycol dicarboxylate (B1) Bisethoxydiglycol dicarboxylate is a compound represented by the following formula (II). [Case 2] R2O-CO-R1-CO-OR2···(II) (In the formula, R1 represents a linear, branched, or cyclic hydrocarbon group having 2 to 10 carbon atoms, and R2 represents an ethoxydiglycol group.) Specific examples of bisethoxydiglycol dicarboxylate include bisethoxydiglycol cyclohexanedicarboxylate, bisethoxydiglycol succinate, bisethoxydiglycol adipate, bisethoxydiglycol sebacate, bisethoxydiglycol phthalate, bisethoxydiglycol terephthalate, and bisethoxydiglycol azelaate. Particularly preferred is bisethoxydiglycol cyclohexanedicarboxylate. As bisethoxydiglycol cyclohexanedicarboxylate, various commercially available products such as "Neosolue-Aqulio" (manufactured by Nippon Fine Chemical Co., Ltd.) can be used. (B1) Bisethoxydiglycol dicarboxylate may be used alone or in combination of two or more.

[0023] Increasing the content of (B1) bisethoxydiglycol dicarboxylate can improve the conditioning effect, but if the content of (B1) bisethoxydiglycol dicarboxylate is too high, too much of (A1) polyquaternium-64 and / or (B1) bisethoxydiglycol dicarboxylate (hereinafter sometimes referred to as the active ingredient) will be adsorbed onto the hair, making the hair sticky and tending to reduce the conditioning effect. The content of (B1) bisethoxydiglycol dicarboxylate in the treatment agent X or the second agent (total if two or more types are used) is preferably 0.05% by mass or more, more preferably 0.1% by mass or more, even more preferably 0.5% by mass or more, and is preferably 15% by mass or less, more preferably 10% by mass or less, even more preferably 4% by mass or less.

[0024] In Treatment Agent X, the first agent, the remaining components other than (A1) Polyquaternium-64 are solvents, and known solvents for hair treatment agents such as water and ethanol can be used as the solvent, with water being preferred. In the second agent, the remaining components other than (B1) bisethoxydiglycol dicarboxylate can be a solvent such as water or ethanol, which is a known solvent for hair treatment agents, and water is preferred. The treatment agent X, the first agent, and the second agent may contain active ingredients such as component (A2), component (A3), and component (B2) described below, as well as various known additives. The hair treatment agent may be composed of treatment agent X; or treatment agent Y consisting of a first agent and a second agent, but may also contain treatment agent Z.

[0025] The hair treatment agent of the present invention can achieve the desired effects described above by using (A1) polyquaternium-64 and (B1) bisethoxydiglycol dicarboxylate in combination, but it is preferable to further contain at least one active additive selected from the group consisting of the following (1) to (3), as this can further improve the conditioning effect and the durability of the conditioning effect. (1) (C1) Amino-modified silicone and (C2) Dicarboxylic acid diester (Treatment Agent Z) (2) (A2) a cationized protein and / or (A3) a cationic surfactant (3) (B2) Anionic polysaccharides

[0026] (1) Treatment Agent Z Treatment agent Z contains (C1) amino-modified silicone and (C2) dicarboxylic acid diester. (C1) amino-modified silicone and (C2) dicarboxylic acid diester must be used together, and when used with (A1) polyquaternium-64 and (B1) bisethoxydiglycol dicarboxylate, the conditioning effect and duration of the conditioning effect can be improved. The effect of adding the above-mentioned treatment agent Z can be obtained when it is applied to the hair together with (A1) polyquaternium-64 and (B1) bisethoxydiglycol dicarboxylate. Before application to the hair, (C1) amino-modified silicone and (C2) dicarboxylate diester are desirably stored in container D, separate from containers B and C, to prevent mixing with (A1) polyquaternium-64 and (B1) bisethoxydiglycol dicarboxylate.

[0027] (C1) Amino-modified silicone (C1) Amino-modified silicone has excellent adhesion to hair and is an ingredient that is effective in treating damage, improving conditioning effects, and improving durability. (C1) Examples of amino-modified silicones include amodimethicones such as aminoethylaminopropylsiloxane-dimethylsiloxane copolymers; (aminoethylaminopropylmethicone / dimethicone) copolymers such as aminoethylaminopropylmethylsiloxane-dimethylsiloxane copolymers; and aminopropyldimethicones such as highly polymerized dimethylsiloxane-methyl(aminopropyl)siloxane copolymers. As the amino-modified silicone, various commercially available products such as "DOWSIL SM 8904 COSMETIC EMULSION," "DOWSIL BY22-079," "DOWSIL FZ-4671," "DOWSIL FZ-4672," and "DOWSIL SS-3551" (manufactured by Dow-Toray) can be used. The amino-modified silicone (C1) may be used alone or in combination of two or more.

[0028] Increasing the content of (C1) amino-modified silicone can improve the conditioning effect and durability. On the other hand, if the content of (C1) amino-modified silicone is too high, it tends to be absorbed into the hair too much, causing it to get caught when combing, and the conditioning effect and durability tend to decrease. The content of (C1) amino-modified silicone in treating agent Z (total if two or more types) is preferably 0.1% by mass or more, more preferably 1% by mass or more, even more preferably 2% by mass or more, and is preferably 10% by mass or less, more preferably 7% by mass or less, even more preferably 5% by mass or less.

[0029] (C2) Dicarboxylic acid diester (C2) Dicarboxylic acid diester is an ingredient that is effective in promoting penetration of active ingredients into hair, and is an ingredient that is effective in repairing damage, improving conditioning effects, and improving durability. (C2) Examples of dicarboxylic acid diesters include adipic acid diesters such as diisopropyl adipate, diisobutyl adipate, diethoxyethyl adipate, and diglyceryl adipate mixed fatty acid esters; succinic acid diesters such as diethoxyethyl succinate and dioctyl succinate; and sebacate diesters such as diethyl sebacate. As the (C2) dicarboxylic acid diester, various commercially available products can be used. (C2) The dicarboxylic acid diesters can be used alone or in combination of two or more.

[0030] Increasing the content of (C2) dicarboxylic acid diester can improve the conditioning effect and durability, but if the content of (C2) dicarboxylic acid diester is too high, too much is adsorbed onto the hair, causing stickiness and tending to reduce the conditioning effect and durability. The content of the (C2) dicarboxylic acid diester in treating agent Z (total if two or more types are used) is preferably 0.01% by mass or more, more preferably 0.1% by mass or more, even more preferably 0.5% by mass or more, and is preferably 7% by mass or less, more preferably 5% by mass or less, even more preferably 2% by mass or less.

[0031] (2) (A2) a cationized protein and / or (A3) a cationic surfactant The conditioning effect can be improved by including at least one of (A2) a cationized protein and (A3) a cationic surfactant, and preferably both. The (A2) cationized protein and / or the (A3) cationic surfactant are preferably contained in the treatment agent X or the first agent.

[0032] (A2) Cationized Protein (A2) Cationic protein is a component that particularly contributes to improving the adhesion (adsorption) of active ingredients to hair. A cationized protein is a compound obtained by cationizing a protein or hydrolyzed protein. Examples of cationized proteins include cationized hydrolyzed keratin, cationized hydrolyzed collagen, cationized hydrolyzed rice protein, cationized hydrolyzed silk, and cationized hydrolyzed casein. Specific examples include N-[2-hydroxy-3-(trimethylammonio)propyl] chloride hydrolyzed keratin, N-[2-hydroxy-3-(trimethylammonio)propyl] chloride hydrolyzed collagen, N-[2-hydroxy-3-(trimethylammonio)propyl] chloride hydrolyzed rice protein, N-[2-hydroxy-3-(trimethylammonio)propyl] chloride hydrolyzed silk, etc. Also included are derivatives such as cetearamidoethyldiethonium hydrolyzed rice protein. These (A2) cationized proteins can be used alone or in combination of two or more.

[0033] Increasing the content of (A2) cationized protein increases the adhesion of the active ingredient to hair, improving the conditioning effect.On the other hand, if the content of (A2) cationized protein is too high, too much of the adhesion-improving ingredient will be adsorbed to the hair, which will cause the hair to get caught when combed and reduce its suppleness, tending to reduce the conditioning effect. The content of the (A2) cationized protein in the treatment agent X or the first agent (total if two or more types are used) is preferably 0.005% by mass or more, more preferably 0.03% by mass or more, even more preferably 0.1% by mass or more, and is preferably 2% by mass or less, more preferably 1.5% by mass or less, even more preferably 1% by mass or less.

[0034] (A3) Cationic surfactant (A3) Cationic surfactant is a component that contributes to improving the smooth feeling of hair and also contributes to improving the conditioning effect. Examples of (A3) cationic surfactants include alkyltrimethylammonium halides, dialkyldimethylammonium halides, alkyldimethylbenzylammonium halides, and tertiary aliphatic amino salts. Specific examples include monoalkyl quaternary ammonium salts such as lauryltrimethylammonium chloride, myristyltrimethylammonium chloride, cetyltrimethylammonium chloride, cetyltrimethylammonium methyl sulfate, palmityltrimethylammonium chloride, stearyltrimethylammonium chloride, and eicosyltrimethylammonium chloride; and di-long-chain alkyl quaternary ammonium salts such as dipalmityldimethylammonium chloride and distearyldimethylammonium chloride. Among these, monoalkyl quaternary ammonium salts are preferred. The cationic surfactant (A3) may be used alone or in combination of two or more.

[0035] Increasing the content of (A3) cationic surfactant can improve the conditioning effect, but if the content of (A3) cationic surfactant is too high, the hair tends to become too soft and difficult to manage. The content of the (A3) cationic surfactant in the treatment agent X or the first agent (total if two or more types are used) is preferably 0.01% by mass or more, more preferably 0.1% by mass or more, even more preferably 0.2% by mass or more, and is preferably 3% by mass or less, more preferably 2% by mass or less, even more preferably 1.5% by mass or less.

[0036] (3) (B2) Anionic polysaccharides (B2) Anionic polysaccharides are ingredients that have a conditioning effect, particularly effective in improving hair manageability. (B2) Examples of anionic polysaccharides include carrageenan, xanthan gum, guar gum, sodium alginate, and sodium carboxymethyldextran, which is the sodium salt of polycarboxymethyl ether of dextran. Of these, sodium carboxymethyldextran is preferred. (B2) Various commercially available anionic polysaccharides can be used. (B2) Anionic polysaccharides can be used alone or in combination of two or more.

[0037] Increasing the content of (B2) anionic polysaccharide can improve the conditioning effect, but if the content of (B2) anionic polysaccharide is too high, the viscosity of the treatment agent becomes too high, making it difficult to apply evenly to the hair, and the active ingredient cannot be sufficiently adsorbed, which tends to deteriorate the conditioning effect. (B2) The content of anionic polysaccharide is 2 The proportion of the agent (total for two or more types) is preferably 0.001% by mass or more, more preferably 0.01% by mass or more, even more preferably 0.1% by mass or more, and is preferably 15% by mass or less, more preferably 5% by mass or less, even more preferably 2% by mass or less.

[0038] In addition to the various active additive components described above, the hair treatment composition of the present invention may also contain, if necessary, various known additives that are incorporated into known hair treatment compositions. Examples of known additives include vegetable oils (olive oil, jojoba oil, shea butter, etc.), fatty acids, hydrocarbons (squalane, liquid paraffin, etc.), oils and fats such as higher alcohols, surfactants (anionic surfactants, amphoteric surfactants, nonionic surfactants), sugars (sorbitol, etc.), fluorine-based compounds, deodorants, preservatives, chelating agents, pH adjusters, solvents, anti-inflammatory agents, thickeners, fragrances, pigments, etc., and these can be blended as appropriate.

[0039] The hair treatment agent of the present invention can be in various forms, such as cream, lotion, emulsion, gel, etc., and can be used and applied widely in hair cosmetics.

[0040] A preferred method of using the hair treatment agent of the present invention will now be described. The hair treatment composition of the present invention is preferably prepared by first shampooing the hair to remove dirt, and then thoroughly removing water to moisten the hair (hereinafter sometimes referred to as pre-washing). In the case of a one-component treatment using treatment agent X, a) apply treatment agent X to the hair and spread it over the entire hair while blending it in. C) It is then preferable to rinse off the hair treatment agent with hot water (hereinafter sometimes referred to as hot water washing).

[0041] When using treatment agent Z in addition to treatment agent X, a) after pre-washing, b) apply treatment agent X to the hair and spread it over the entire hair while blending it in, and then, without removing treatment agent X, i.e., without rinsing it off, d) apply treatment agent Z to the hair and spread it over the entire hair while blending it in. C) It is preferable to then wash it with hot water.

[0042] In the case of a two-component treatment agent using a first agent and a second agent, the order of application of the first and second agents is not particularly limited as long as both the first and second agents are applied to the hair. Therefore, any of the following application forms I to III may be used. I: a) After pre-washing, apply Ka-1) the first agent to the hair and spread it over the entire hair while blending it in. Then, without removing the first agent, i.e., without rinsing the first agent off, apply Ka-2) the second agent to the hair and spread it over the entire hair while blending it in. II: a) After pre-washing, apply Ka-3) Agent 2 to the hair and spread it over the entire hair while blending it in. Then, without removing Agent 2, i.e., without rinsing it off, apply Ka-4) Agent 1 to the hair and spread it over the entire hair while blending it in. III: a) After pre-washing, (c) (5) prepare a mixture by mixing the first agent and the second agent, and then (c) (6) apply the mixture to the hair and spread it over the entire hair while blending it in. C) After the above steps C-2), C-4), and C-6), it is preferable to wash with hot water.

[0043] When using treatment agent Z in addition to the two-component treatment agent, After I:A) → Ka-1) → Ka-2) above, or After II: A) → K-3) → K-4) above, or After the above III: A) → Ka-5) → Ka-6), (c) Without rinsing with hot water, i.e., with the first and second agents applied to the hair, (g) apply treatment agent Z to the hair and spread treatment agent Z over the entire hair, blending it in. After that, it is preferable to wash with hot water.

[0044] In the present invention, the treatment agent may be applied to the hair and then left for, for example, 5 to 30 minutes. By leaving the agent on for a certain period of time, the penetration and absorption of each ingredient into the hair is further promoted, improving the conditioning effect and its durability. Such leaving is preferably carried out, for example, between I and C, between I and D, between Ka-1 and Ka-2, between Ka-2 and C, between Ka-2 and G, between Ka-3 and Ka-4, between Ka-4 and C, between Ka-4 and G, between Ka-6 and C, and between Ka-6 and G. When multiple applications of the treatment agent are performed, the treatment agent may be left to stand between applications, or between any of the applications.

[0045] If the hair is severely damaged, after applying each treatment to the hair, the treatment may be heated and left to stand using a steamer, rollerball, or the like, and then rinsed off with hot water. By leaving the treatment to stand, the penetration and adsorption of each ingredient is further promoted, improving the conditioning effect and its sustained effect. The heating temperature for leaving the treatment to stand is, for example, 30°C to 60°C. The time for leaving the treatment to stand at that temperature is, for example, 5 to 30 minutes. [Example]

[0046] The present invention will be described in more detail below with reference to examples. However, the present invention is not limited to the following examples, and it is possible to carry out the invention by making appropriate modifications within the scope of the above and below-described aims, and all such modifications are included in the technical scope of the present invention.

[0047] (Bleach treatment) Hair bundles were prepared that had not undergone any chemical treatments, such as perming, hair coloring, or bleaching. A 1:3 mixture of powder bleach (Caradeco Toner Bleach Powder EX, manufactured by Nakano Pharmaceutical Co., Ltd.) and hydrogen peroxide-based oxidizing agent (Caradeco Oxide N06, manufactured by Nakano Pharmaceutical Co., Ltd.) was applied to the hair in a 1:1 mass ratio. The mixture was then left at 35°C for 30 minutes and then washed with a 45% by mass solution of triethanolamine lauryl sulfate. The triethanolamine lauryl sulfate solution was then rinsed off with hot water, and the hair was then completely dried with a hair dryer. This process (bleaching → washing with triethanolamine lauryl sulfate solution → hot water rinsing → drying) was repeated three times. The resulting bleached hair bundles were used to prepare evaluation samples. The bleached hair bundle used to prepare each evaluation sample was 20 cm long and weighed 15 g.

[0048] (Preparation of evaluation samples) After the bleached hair was thoroughly rinsed with hot water (hereinafter referred to as pre-washing), one of the following treatments was performed using a hair treatment agent. Treatment 1: 1.0 g of treatment agent X containing both component (A1) and component (B1) was applied to a hair bundle, and then treatment agent X was thoroughly rinsed off with running water. The hair bundle was then completely dried with a hair dryer. Treatment 2: 1.0 g of treatment agent A (first agent) containing component (A1) was applied to the hair bundle, followed by 2.0 g of treatment agent B (second agent) containing component (B1). After application, treatment agents A and B were thoroughly rinsed off with running water. The hair bundle was then completely dried with a hair dryer. Treatment 3: After applying 2.0 g of treatment agent B (second agent) containing component (B1), 1.0 g of treatment agent A (first agent) containing component (A1) was applied to the hair bundle. After application, treatment agents A and B were thoroughly rinsed off with running water. The hair bundle was then completely dried with a hair dryer. Depending on the formulation, component (A1) may not be contained in treatment agent A, and component (B1) may not be contained in treatment agent B. The component compositions of the treatment agents used in each treatment are as shown in Tables 1 to 7. Each sample obtained after treatment with the hair treatment agent was evaluated according to the following criteria, with Examples 2-4 being used as the evaluation criteria.

[0064] Example 1 Hair treatment was performed using the combinations shown in Table 10 of Treatment Agent A (Formulation Examples I-1 to I-9; Formulations I-31 to 38), which is the first agent shown in Table 1, Treatment Agent B (Formulation Example II-4), which is the second agent shown in Table 2, and Treatment Agent X (Formulation Examples I and II-1 containing I-3 and II-4; Formulations I and II-2 containing I-8 and II-8), which is shown in Table 3. The examples not containing component (A1) are comparative examples. The evaluation results are shown in Table 10.

[0065] [Table 10]

[0066] In Example 1, the effects of the content of (A1) polyquaternium-64 in treatment agent A on the smoothness, suppleness, and manageability of hair were examined. In Experiments 1 to 7, which used Treatment A containing (A1) Polyquaternium-64, all of the treatments had excellent conditioning effects, and were able to impart an especially excellent smooth feeling to the hair. As the amount of (A1) Polyquaternium-64 increased, the smooth feeling of the hair tended to improve, but if the content was too high, the smooth feeling of the hair tended to decrease. In Experiment No. 10, in which treatment agent A containing (A1) polyquaternium-64 was applied after treatment agent B; Experiment No. 11, in which treatment agents A and B containing (A1) polyquaternium-64 were mixed and then applied; and Experiment No. 12, in which treatment agent X containing (A1) polyquaternium-64 and (B1) bisethoxydiglycol cyclohexanedicarboxylate was applied, all of these experiments were able to impart excellent conditioning effects, such as an excellent smooth feel, to hair. These examples demonstrate that, regardless of the order of application, excellent conditioning effects can be obtained as long as the specified ingredients are applied to the hair. On the other hand, in Experiments Nos. 8 to 9 and 13 to 20 in which Treatment Agent A not containing (A1) Polyquaternium-64 was used, the conditioning effect was poor, and the smooth feeling could not be imparted to the hair.

[0067] Example 2 Hair was treated with treatment agent A (formulation example I-3) shown in Table 1 and treatment agent B (formulation examples II-1 to II-9, II-31 to II-38) shown in Table 2 in the combinations shown in Table 11. The evaluation results are shown in Table 11.

[0068] [Table 11]

[0069] In Example 2, the effects of the content of (B1) bisethoxydiglycol cyclohexanedicarboxylate in Treatment Agent B on the smooth feel, suppleness, and manageability of hair were investigated. In Experiments 1-1 to 1-6, excellent conditioning effects were obtained, and an especially excellent smooth feeling was imparted. As the amount of (B1) bisethoxydiglycol cyclohexanedicarboxylate increased, the smooth feeling of hair tended to improve, but if the content was too high, the smooth feeling of hair tended to decrease. On the other hand, in Experiments Nos. 1-7 to 1-16 in which Treatment Agent B not containing (B1) bisethoxydiglycol cyclohexanedicarboxylate was used, conditioning effects such as smoothness could not be imparted to the hair.

[0070] Example 3 Hair treatments were performed using treatment agent A (formulation examples I-8 and I-9) shown in Table 1, treatment agent B (formulation examples II-8 and II-9) and treatment agent X (formulations I and II-2) shown in Table 2 in combination as shown in Table 12. The evaluation results are shown in Table 12.

[0071] [Table 12]

[0072] In Example 3, the influence on conditioning effect when treatment agent A did not contain (A1) polyquaternium-64 and treatment agent B did not contain (B1) bisethoxydiglycol cyclohexanedicarboxylate was examined. In Experiments Nos. 2-1 to 2-5, which used treatment agents that did not contain (A1) Polyquaternium-64 and (B1) bisethoxydiglycol cyclohexanedicarboxylate, it was not possible to impart smoothness, suppleness, and manageability to the hair.

[0073] Example 4 Hair treatment was performed using treatment agent A (formulation examples I-4, I-10 to I-18) shown in Tables 1 and 4 and treatment agent B (formulation example II-4) shown in Table 2 in combination as shown in Table 13. The evaluation results are shown in Table 13.

[0074] [Table 13]

[0075] In Example 4, the effects of (A2) cationized protein and (A3) cationic surfactant in Treatment Agent A on the smoothness, suppleness, and manageability of hair were examined. In Experiments 3-1 to 3-8, which used Treatment A containing (A2) cationic protein and / or (A3) cationic surfactant, the hair was given a smooth feel, suppleness, and manageability, and excellent conditioning effects were obtained. In Experiments 4 and 3-9, which used Treatment A without (A2) cationic protein and (A3) cationic surfactant, the effects on hair suppleness and manageability were inferior to Experiments 3-1 to 3-8.

[0076] Example 5 Hair treatment was performed using treatment agent A (Formulation Examples I-19 to I-28) shown in Table 5 and treatment agent B (Formulation Example II-4) shown in Table 2 in combination as shown in Table 14. The evaluation results are shown in Table 14.

[0077] [Table 14]

[0078] In Example 5, the effects of the contents of (A2) cationized protein and (A3) cationic surfactant in Treatment A on the smoothness, suppleness, and manageability of hair were investigated. (A2) In Experiments Nos. 4-2 to 4-4, which used Treatment Agent A with a cationic protein content of 0.05% or more and 1.5% or less, and (A3) in Experiments Nos. 4-7 to 4-9, which used Treatment Agent A with a cationic surfactant content of 0.025% or more and 1.75% or less, the smoothness, suppleness, and manageability of hair were further improved.

[0079] Example 6 Hair treatment was performed using treatment agent A (prescription example I-14) shown in Table 4 and treatment agent B (prescription examples II-4, II-10 to II-13) shown in Tables 2 and 6 in combination as shown in Table 15. The evaluation results are shown in Table 15.

[0080] [Table 15]

[0081] In Example 6, the effects of (B2) anionic polysaccharide in Treatment Agent B on the smooth feel, suppleness, and manageability of hair were examined. Comparing Experiments Nos. 3-5 and 5-4, which used Treatment Agent B that did not contain (B2) anionic polysaccharides, with Experiments Nos. 5-1 to 5-3, which used Treatment Agent B that contained (B2) anionic polysaccharides, it was found that the inclusion of (B2) anionic polysaccharides imparted a smooth feeling and suppleness to the hair, and in particular improved the manageability of the hair.

[0082] Example 7 Hair was treated using treatment agent A (prescription example I-14) shown in Table 4 and treatment agent B (prescription examples II-14 to II-19) shown in Table 7 in combination as shown in Table 16. The evaluation results are shown in Table 16.

[0083] [Table 16]

[0084] In Example 7, the effects of the content of (B2) anionic polysaccharide in Treatment Agent B on the smooth feel, suppleness, and manageability of hair were investigated. (B2) In Experiments No. 6-1 to 6-4) using Treatment Agent B with an anionic polysaccharide content of 0.001% or more and 1.5% or less, the condition of the hair improved in at least two of the following areas: smoothness, suppleness, and manageability.

The evaluation results are shown in Table 17.

[0086] [Table 17]

[0087] In Example 8, the effects of (C1) amino-modified silicone and (C2) dicarboxylic acid diester of treatment agent Z on the conditioning effect and the durability of the conditioning effect were investigated. Compared to Experiments No. 7-1 to 7-4, which used treatment agent Z containing only either (C1) amino-modified silicone or (C2) dicarboxylic acid diester, Experiments No. 7-5 to 7-8, which used treatment agent Z containing both (C1) amino-modified silicone and (C2) dicarboxylic acid diester, had excellent conditioning effect and its durability, and the durability of the conditioning effect was particularly good. Experiments Nos. 7-5, 7-10, and 7-11 were examples in which the order of addition of the additive treatments was changed, but all of them showed excellent durability. On the other hand, in Experiment Nos. 7-9, which used Treatment Agent Z containing neither (C1) amino-modified silicone nor (C2) dicarboxylic acid diester, the conditioning effect did not last long.

[0088] Example 9 Hair treatment was performed using the combinations shown in Table 18 of Treatment Agent A (Formulation Example I-14) shown in Table 4, Treatment Agent B (Formulation Example II-10) shown in Table 6, and Treatment Agent Z (Formulation Examples III-10 to III-19) shown in Table 9. The evaluation results are shown in Table 18.

[0089] [Table 18]

[0090] In Example 9, the influence of the content of (C1) amino-modified silicone and (C2) dicarboxylic acid diester on the conditioning effect and its durability was investigated. Experiments Nos. 8-2 to 8-4, which used treatment agent Z with a content of (C1) amino-modified silicone of 1.25% or more and 7.5% or less, and Experiments Nos. 8-7 to 8-9, which used treatment agent Z with a content of (C2) dicarboxylic acid diester of 0.03% or more and 2.5% or less, showed better conditioning effect and durability.
