Description

The present invention relates to a multi-component hair treatment agent.

As a hair treatment agent, one containing amino-modified silicone is known (see JP-A-2013-40153). The hair treatment agent described in this publication is constructed as a multi-component formula, and is used by applying a first component and a second component containing an amino-modified silicone in this order.

By blending amino-modified silicone into a hair treatment agent in this way, hair can be conditioned. However, even if the hair is sufficiently conditioned by blending the amino-modified silicone, there is a risk that the effect of the blend may not be felt. Specifically, regarding the feeling of thickness when touching the hair (the feeling that the surface of the hair is coated with some kind of substance), the feeling becomes superficial and the thickness feels like it is stuck inside the hair. If you lack a certain sensation, you may not be able to feel that such a conditioning effect is being obtained.

Japanese Patent Application Publication No. 2013-40153

The present invention has been made in view of the above-mentioned circumstances, and aims to provide a multi-component hair treatment agent and its constituents that give the hair a thick feel as if the inside of the hair is clogged.

（式（Ｉ）中、Ｒ^１は、炭素数１２～２２のアルキル基である。Ｒ^２は、メチル基又は炭素数１２～２２のアルキル基である。Ｘは、ハロゲン原子である。） The invention made in order to solve the above problem is a multi-component hair treatment agent comprising a first agent and a second agent used after the first agent, wherein the first agent has the following formula ( A quaternary ammonium salt represented by I), a higher alcohol, and at least one of a water-soluble polysaccharide and a water-soluble polysaccharide derivative are blended into the second agent, and the second agent is represented by the following formula (I). It is characterized by containing a quaternary ammonium salt, a higher alcohol, and an amino-modified silicone.

(In formula (I), R ¹ is an alkyl group having 12 to 22 carbon atoms. R ² is a methyl group or an alkyl group having 12 to 22 carbon atoms. X is a halogen atom.)

According to the multi-component hair treatment agent, by incorporating a water-soluble polysaccharide or a water-soluble polysaccharide derivative (hereinafter also collectively referred to as "water-soluble polysaccharide etc.") into the first agent, After treatment, you can get a thick feeling (thickness) as if the inside of the hair is clogged. The effect of obtaining such a thick feeling is not clear, but when the second part is applied after the first part, the water-soluble polysaccharides, etc. of the first part are coated inside the amino-modified silicone of the second part. This is thought to be because the presence of the film gives a feeling that the inside of the amino-modified silicone is clogged.

The amount of amino-modified silicone in the first part is preferably 1% by mass or less and less than the amount of amino-modified silicone in the second part. By blending the amino-modified silicone in such an amount, it becomes possible to effectively form a film of water-soluble polysaccharide or the like inside the amino-modified silicone of the second agent. This makes it easier to feel that a conditioning effect based on the thickness is being obtained when touching the hair after treatment.

The water-soluble polysaccharide or water-soluble polysaccharide derivative blended in the first agent is hydroxypropyl starch phosphate, hydrophobized hydroxypropyl methyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, sodium carboxymethyl cellulose, cationized cellulose, or cationic It is good if it is guar gum.

The blending amount of the amino-modified silicone in the second agent is preferably 3% by mass or more.

When the amount of the amino-modified silicone is 3% by mass or more, the second agent preferably contains cationized cellulose. In this way, by incorporating cationized cellulose into the second agent, when washing with water after application of the multi-component hair treatment agent, the oily and difficult running of the hair due to amino-modified silicone is improved, and the feeling of rinsing is improved. do.

The amount of cationized cellulose in the second part is preferably 2 parts by mass or more and 40 parts by mass or less based on 100 parts by mass of the amino-modified silicone of the second part. By setting the blending amount of cationized cellulose within the above-mentioned range relative to the blending amount of the amino-modified silicone of the second agent, the flushing feeling during washing with water after application is further improved.

The dosage form of the first agent and the second agent is preferably cream-like. Since the dosage form of the first agent and the second agent is cream-like as described above, the first agent and the second agent have excellent handling properties when applied to the hair. In addition, by standardizing the formulation of the first and second agents into a cream-like formulation, it is not only easier for the first and second agents to blend into each other, but it also allows the first and second agents to blend into the hair. It becomes easier.

（式（Ｉ）中、Ｒ^１は、炭素数１２～２２のアルキル基である。Ｒ^２は、メチル基又は炭素数１２～２２のアルキル基である。Ｘは、ハロゲン原子である。） Another invention made to solve the above problems includes a first agent, a quaternary ammonium salt, a higher alcohol, and an amino-modified silicone used after the first agent and represented by the following formula (I).

The multi-component hair treatment agent of the present invention includes a first agent and a second agent used after the first agent.

[First agent]
The first agent contains a quaternary ammonium salt, a higher alcohol, a water-soluble polysaccharide, and the like. The first agent may contain amino-modified silicone, and may contain other optional components as long as the effects of the present invention are not impaired. These components will be explained in detail below.

<Quaternary ammonium salt>
When the quaternary ammonium salt is mixed with the higher alcohol, the dosage form of the first agent becomes cream-like or close to cream-like. This quaternary ammonium salt is represented by the following formula (I).

In the above formula (I), R ¹ is an alkyl group having 12 to 22 carbon atoms. R ² is a methyl group or an alkyl group having 12 to 22 carbon atoms. X is a halogen atom. Examples of the halogen atom include chlorine, bromine, and iodine.

Examples of the quaternary ammonium salt represented by the above formula (I) include salts of trimethyl quaternary ammonium such as myristyltrimethylammonium, cetyltrimethylammonium, stearyltrimethylammonium, and behenyltrimethylammonium; Examples include salts of dimethyl quaternary ammonium such as cetyldimethylammonium, distearyldimethylammonium, and dibehenyldimethylammonium. These quaternary ammonium salts may be blended alone or in combination of two or more.

<Higher alcohol>
The higher alcohol is blended with the quaternary ammonium salt to make the dosage form of the first agent cream-like or close to cream-like. Examples of such higher alcohols include linear saturated alcohols such as myristyl alcohol, cetanol, stearyl alcohol, and behenyl alcohol; linear unsaturated alcohols such as oleyl alcohol; and branched alcohols such as octyldodecanol, isostearyl alcohol, and hexyldecanol. Examples include saturated alcohol. These higher alcohols may be blended alone or in combination of two or more. The blending amount of the higher alcohol in the first agent is, for example, 0.5% by mass or more and 5% by mass or less.

<Water-soluble polysaccharides, etc.>
The water-soluble polysaccharide and the like give a feeling of thickness to the hair treated with the multi-component hair treatment agent.

The water-soluble polysaccharides include water-soluble polysaccharides and water-soluble polysaccharide derivatives. Examples of water-soluble polysaccharides include hydroxypropyl starch phosphate; hydrophobized hydroxypropyl methyl cellulose such as stearoxyhydroxypropyl methyl cellulose; hydroxyalkyl cellulose such as hydroxyethyl cellulose and hydroxypropyl cellulose; sodium carboxymethyl cellulose; O-[2- Examples include cationized cellulose such as hydroxy-3-(trimethylammonio)propyl]hydroxyethylcellulose; cationized guar gum such as O-[2-hydroxy-3-(trimethylammonio)propyl]guar gum chloride. These water-soluble polysaccharides and the like may be blended alone or in combination of two or more. The amount of the water-soluble polysaccharide and the like in the first agent is, for example, 0.5% by mass or more and 10% by mass or less, and preferably 2% by mass or more and 8% by mass or less.

<Optional ingredients>
(amino modified silicone)
Amino-modified silicones are mainly blended to impart conditioning effects to hair. Here, the amino-modified silicone is a silicone in which an amino group is bonded to a silicone skeleton directly or via a substituent.

The blending amount of the amino-modified silicone in the first agent is, for example, 1% by mass or less. That is, since the amino-modified silicone is an optional component in the first agent, it is not necessary to include the amino-modified silicone.

When blending an amino-modified silicone into the first part, it is preferable to mix the same amino-modified silicone that can be blended into the second part into the first part. Examples of the amino-modified silicone of the first agent include aminoethylaminopropylmethylsiloxane/dimethylsiloxane copolymer ((aminoethylaminopropylmethicone/dimethicone) copolymer), aminoethylaminopropylsiloxane/dimethylsiloxane copolymer (amodimethicone) ), aminopropyl dimethicone (aminopropylmethylsiloxane/dimethylsiloxane copolymer), highly polymerized aminopropyl dimethicone, aminopolyether modified silicone, aminoglycol modified silicone, acrylic/amino modified silicone, aminophenyl modified silicone, etc. These amino-modified silicones may be blended alone or in combination of two or more.

Examples include substances derived from microorganisms, inorganic compounds, fragrances, preservatives, sequestrants, ultraviolet absorbers, and the like.

<pH>
The pH of the first agent at 25° C. is preferably 3 or more and 7 or less. If the pH of the first agent exceeds 7, the hair will swell when the first agent is applied to the hair, which is not preferable.

<Dosage form, viscosity, etc.>
The dosage form of the first agent is preferably cream-like with an aqueous external phase. By making the dosage form of the first agent cream-like in this way, the first agent has excellent handling properties when applied to the hair, and it also becomes easier to blend the first agent into the hair. In addition, "the outer phase is an aqueous phase" means a form in which the outermost phase is an aqueous phase, and means, for example, an emulsion such as W/O or W/O/W. Further, the amount of water blended in the first agent in the case of making it creamy is, for example, 70% by mass or more and 95% by mass or less.

The viscosity of the first agent is, for example, 1,000 mPa·s or more and 60,000 mPa·s or less when the first agent is in the form of a cream having an aqueous external phase. Note that the viscosity may be measured using a stress-controlled rheometer ("Rheo Stress 6000" manufactured by HAAKE). The viscosity measurement conditions may be, for example, a measurement temperature of 25° C., a cone-plate sensor diameter of 35 mm and an inclination angle of 2°, a steady flow curve mode, a waiting time of 1 minute, and a shear rate of 36 s ⁻¹ .

[Second agent]
The second agent contains a quaternary ammonium salt, a higher alcohol, and an amino-modified silicone. The second agent may contain cationized cellulose, and may contain other optional components as long as the effects of the present invention are not impaired. These components will be explained in detail below.

<Quaternary ammonium salt>
When mixed with a higher alcohol, the quaternary ammonium salt makes the dosage form of the second agent cream-like or close to cream-like. The quaternary ammonium salt that can be blended in the first part can be used as the quaternary ammonium salt that can be blended in the second part. The amount of the quaternary ammonium salt in the second agent is set as appropriate, and is, for example, 1% by mass or more and 7% by mass or less.

<Higher alcohol>
The higher alcohol that can be blended into the first agent can be used as the higher alcohol that can be blended into the second agent. The amount of higher alcohol blended in the second agent is appropriately set, and is, for example, 5% by mass or more and 15% by mass or less.

<Amino-modified silicone>
Amino-modified silicones are mainly blended to impart conditioning effects to hair. Here, the amino-modified silicone is a silicone in which an amino group is bonded to a silicone skeleton directly or through a substituent as described above. Examples of the amino-modified silicone include compounds represented by the following formula (1) and the following formula (2).

In the above formula (1), x and y are integers of 1 to 5, and m and n are integers that depend on the molecular weight.

In the above formula (2), v and w are integers of 1 to 5, and p and q are integers that depend on the molecular weight.

Examples of the compound represented by the above formula (1) include aminoethylaminopropylmethylsiloxane/dimethylsiloxane copolymer ((aminoethylaminopropylmethicone/dimethicone) copolymer) where x=3 and y=2. It will be done. Further, examples of the compound represented by the above formula (2) include aminoethylaminopropylsiloxane/dimethylsiloxane copolymer (amodimethicone) in which v=3 and w=2.

In addition to the above, specific examples of amino-modified silicones (including cosmetic labeling names) that can be blended into the second agent include aminopropyl dimethicone (aminopropylmethylsiloxane/dimethylsiloxane copolymer), Examples include polymerized aminopropyl dimethicone, aminopolyether-modified silicone, aminoglycol-modified silicone, acrylic/amino-modified silicone, and aminophenyl-modified silicone. These amino-modified silicones may be blended alone or in combination of two or more.

The amino-modified silicone in the second part is an essential component, unlike the amino-modified silicone in the first part, which is an optional component. The blending amount of the amino-modified silicone in the second agent is, for example, 3% by mass or more. On the other hand, the upper limit of the blending amount of the amino-modified silicone is not particularly limited, but is preferably 8% by mass, more preferably 7% by mass, and even more preferably 6% by mass. In this way, by setting the blending amount of the amino-modified silicone within the above range, a sufficient conditioning effect can be imparted to the hair after treatment, and the occurrence of hardness and stickiness of the hair can be reduced.

The amino content (nitrogen content in the amino-modified silicone) of the amino-modified silicone is preferably 0.5% by mass or more and 3.0% by mass or less, more preferably 0.7% by mass or more and 2.2% by mass or less. By setting the amino content of the amino-modified silicone within the above range, the above-mentioned conditioning effect can be suitably achieved.

<Optional ingredients>
(cationized cellulose)
Cationized cellulose improves the oily and difficult rinsing caused by amino-modified silicone when washing with water after application of the multi-component hair treatment agent, and improves the rinsing feeling. Examples of such cationized cellulose include O-[2-hydroxy-3-(trimethylammonio)propyl]hydroxy chloride, which is a polymer of quaternary ammonium salt obtained by adding glycidyltrimethylammonium chloride to hydroxyethylcellulose. Ethyl cellulose is mentioned. Commercial products of the cationized cellulose include, for example, "UCARE Polymer JR-30M" manufactured by Dow Chemical Japan, "Cachinal HC-200" manufactured by Toho Chemical Industries, Ltd., "Cachinal LC-200" manufactured by Toho Chemical Industries, Ltd. Examples include "Kachinal LC-100" by Toho Chemical Industry Co., Ltd., "POLYQUTA 3000KC" by KCI, and "Poise C-80M" by Kao Corporation.

The cationized cellulose preferably has a viscosity of 10,000 mPa·s or more and 40,000 mPa·s or less, more preferably 20,000 mPa·s or more and 40,000 mPa·s or less when made into a 2% by mass aqueous solution. . As this viscosity increases, the viscosity of the second agent also tends to increase. Regarding the viscosity of a 2% by mass aqueous solution of cationized cellulose, the value taken 60 seconds after the start of measurement using a B-type viscometer at 25° C., M4 rotor, and 12 rpm is adopted.

The degree of cationization (percentage of nitrogen content in cationized cellulose) of the cationized cellulose is not particularly limited, but is preferably 1.0% or more and 2.0% or less. The nitrogen content is the content of nitrogen atoms contained in cationized cellulose, and a value based on the nitrogen quantitative method defined in the quasi-drug raw material standards is adopted. However, if the quasi-drug raw material standards do not specify a nitrogen quantitative method, the value based on the Kjeldahl method will be adopted.

The amount of cationized cellulose in the second part is preferably 2 parts by mass or more and 40 parts by mass or less based on 100 parts by mass of the amino-modified silicone of the second part. By setting the amount of cationized cellulose in the above-mentioned range relative to the amount of amino-modified silicone in the second agent, it is suitable for improving the flushing feeling when washing with water after applying the second agent.

(Other optional ingredients)
Other optional components of the second agent include, for example, nonionic surfactants, amphoteric surfactants, lower alcohols, polyhydric alcohols, sugars, ester oils, fats and oils, hydrocarbons, waxes, silicones other than amino-modified silicones, and polymers. Examples include compounds, amino acids, animal and plant extracts, microorganism-derived substances, inorganic compounds, fragrances, preservatives, metal ion sequestrants, ultraviolet absorbers, and the like.

<pH>
The pH of the second agent at 25° C. is preferably 3 or more and 7 or less. If the pH of the second agent exceeds 7, the hair will swell when the second agent is applied to the hair, which is not preferable.

<Dosage form, viscosity, etc.>
The dosage form of the second agent is preferably cream-like with an aqueous external phase. As described above, since the second agent has a cream-like dosage form, the second agent has excellent handling properties when applied to the hair, and the second agent can be easily absorbed into the hair. Moreover, when both the first agent and the second agent are in a cream-like dosage form, the first agent and the second agent become more compatible. The definition of "the external phase is an aqueous phase" is the same as in the case of the first agent. In addition, the amount of water in the second agent in the case of making it creamy is, for example, 50% by mass or more and 90% by mass or less.

The viscosity of the second agent is, for example, 1,000 mPa·s or more and 60,000 mPa·s or less when the second agent is a cream-like dosage form with an aqueous external phase. Note that the viscosity may be measured using a stress-controlled rheometer ("Rheo Stress 6000" manufactured by HAAKE). The viscosity measurement conditions may be, for example, a measurement temperature of 25° C., a cone-plate sensor diameter of 35 mm and an inclination angle of 2°, a steady flow curve mode, a waiting time of 1 minute, and a shear rate of 36 s ⁻¹ .

[Applications of multi-component hair treatment agent]
The multi-component hair treatment agent can be used as a hair care agent. A "hair care agent" is a hair treatment agent used to care for, treat, etc. hair. Examples of hair care agents include conditioners and treatments. Treatments include, for example, a treatment used after shampooing, a treatment for pre-treatment of perm, a treatment for post-perm treatment, a treatment for pre-coloring treatment, a treatment for post-coloring treatment, and bleach. These include pre-treatment treatments and post-bleach treatments.

[How to use multi-component hair treatment agent]
The multi-component hair treatment agent is used by applying the first agent and then rinsing off the first agent, or by applying the second agent without rinsing off the first agent. The second agent may or may not be washed away after application.

In the case of a two-component hair treatment agent consisting of two treatment agents, the multi-component hair treatment agent is composed of a first agent and a second agent. When the multi-component hair treatment agent is composed of three or more treatment agents, it contains one or more other treatment agents in addition to the first and second agents. In this case, the first agent, the second agent, and one or more other processing agents may be used in any order as long as the second agent is used after the first agent. For example, after a three-part hair treatment, another treatment agent may be used before the first part, between the first part and the second part, or after the second part. You can use it later.

Hereinafter, the multi-component hair treatment agent and its components will be explained with reference to examples, but the present invention is not limited to the following examples.

In this example, a three-component hair treatment agent was evaluated for thickness, smoothness, and gloss.

In Examples 1a and 1b and Comparative Example 1, a three-part hair treatment agent consisting of a pre-treatment agent, a first part, and a second part was prepared.

<Preparation of pretreatment agent>
The pretreatment agents of Examples 1a, 1b and Comparative Example 1 were 1% by mass of hydrolyzed keratin, 0.4% by mass of sodium lysine dilauroylglutamate, and polyoxyethylene coconut oil fatty acid sorbitan (20E.O.) based on water. 2% by mass, 5% by mass of 1,3-butylene glycol, 0.05% by mass of diethoxyethyl succinate, 0.02% by mass of lactic acid, 0.4% by mass of preservative, and 0.2% by mass of fragrance, It was prepared into a liquid dosage form with high fluidity.

<Preparation of first agent>
The first agents of Examples 1a and 1b and Comparative Example 1 were prepared into cream-like dosage forms by blending the raw materials shown in Table 1 below with water. The pH (25°C) of these first agents was in the range of 4.0 to 5.0.

<Preparation of second agent>
As the second agent of Examples 1a and 1b and Comparative Example 1, cream-like products were prepared by blending raw materials with the following concentrations with water. Setanol 5% by mass, behenyltrimethylammonium chloride 3% by mass, behentrimonium methosulfate 0.1% by mass, isoalkyl (C10-40) amidopropylethyldimonium ethosulfate 0.1% by mass, 1,3-butylene glycol 3 Mass%, isopropanol 0.7% by mass, castor oil 3% by mass, jojoba oil 3% by mass, shea butter 0.5% by mass, aminoethylaminopropylmethylsiloxane/dimethylsiloxane copolymer (amino-modified silicone) 3% by mass , 3% by mass of aminopropylphenyl trimethicone, 2% by mass of methylphenylpolysiloxane, 0.3% by mass of polypropylsilsesquioxane, 0.9% by mass of phenylpropyldimethylsiloxysilicate, 4% by mass of decamethylcyclopentasiloxane, (Hydrolyzed silk/PG-propylmethylsilanediol) Crosspolymer 0.2% by mass, hydrolyzed protein 0.2% by mass, preservative 0.3% by mass, lactic acid 0.2% by mass, and fragrance 0.4% by mass

[evaluation]
The three-component hair treatment compositions of Examples 1a and 1b and Comparative Example 1 were evaluated for thickness, smoothness, and gloss using the methods described below.

<Hair to be evaluated>
The hair to be evaluated was hair that had a history of being dyed with an oxidative hair dye and that had grown below the shoulders.

<Hair treatment method>
First, a pretreatment agent, a first agent, and a second agent were applied to the hair in this order, and then washed with water. Specifically, after applying the three-component hair treatment agent of Comparative Example 1 to half of the hair, and applying the three-component hair treatment agent of Example 1a or Example 1b to the remaining half of the hair, I washed it with water. Next, the entire hair was shampooed and washed with water again, and the entire hair was further treated, washed with water, and then dried.

<Evaluation method>
Thickness, smoothness, and gloss were evaluated by palpating or visualizing the hair treated by the above method. Each evaluation was conducted using four evaluators according to the following criteria as a comparison with the hair treatment agent of Comparative Example 1 (standard). The evaluation results are shown in Table 1. In addition, "thickness" refers to the feeling of being thick inside, "smoothness" refers to the smooth and even texture of the hair surface, and "shininess" refers to the shine that results from the smoothness of the hair surface. It was evaluated as

〇: 3 or more evaluators evaluated it as better than the standard (Comparative Example 1) △: 2 evaluators evaluated it as equivalent to the standard (Comparative Example 1) ×: 3 or more evaluators evaluated it as better than the standard (Comparative Example 1) Example 1) Evaluated as worse

As is clear from Table 1, the three-component hair treatment agents of Examples 1a and 1b had better thickness than the three-component hair treatment agent of Comparative Example 1. From this result, it is thought that in a multi-component hair treatment agent in which an amino-modified silicone is blended in the second part, the thickness feeling is improved by blending a water-soluble polysaccharide or its derivative in the first part.

Furthermore, the three-component hair treatment agent of Example 1b had better shine than the three-component hair treatment agent of Comparative Example 1. From this result, it is considered that the luster is improved by adding carboxymethylcellulose sodium as a water-soluble polysaccharide or the like to the first agent.

[Example 2a, 2b]
In Examples 2a and 2b, a three-component hair treatment agent consisting of a pretreatment agent, a first agent, and a second agent was prepared, and the thickness, smoothness, and gloss were evaluated in the same manner as described above. However, as a standard for comparison, the three-component hair treatment agent of Example 2b was used. The evaluation results are shown in Table 2.

<Preparation of pretreatment agent>
Examples 2a and 2b The same pretreatment agent as in Example 1a was used as the pretreatment agent.

<Preparation of first agent>
The first agents of Examples 2a and 2b were prepared into cream-like dosage forms by blending the raw materials shown in Table 2 below with water. The pH (25°C) of these first agents was in the range of 4.0 to 5.0.

<Preparation of second agent>
As the second agent in Examples 2a and 2b, a cream-like product was prepared by blending raw materials with the following concentrations with water. Setanol 7% by mass, behenyl alcohol 1% by mass, octyldodecanol 3% by mass, stearyltrimethylammonium bromide 3% by mass, ethyl sulfate lanolin fatty acid aminopropylethyldimethylammonium 0.1% by mass, glycerin monostearate 1% by mass, polyester Oxyethylene oleyl ether (2E.O.) 4% by mass, polyoxyethylene sorbitol tetraoleate (60E.O.) 2% by mass, 1,3-BG 3% by mass, isopropanol 1% by mass, aminoethylaminopropylmethylsiloxane・Dimethylsiloxane copolymer (amino-modified silicone) 5% by mass, decamethylcyclopentasiloxane 2% by mass, O-[2-hydroxy-3-(trimethylammonio)propyl]hydroxyethylcellulose chloride 0.7% by mass, trehalose 0.9% by mass, preservative 0.5% by mass, lactic acid 0.4% by mass, and fragrance 0.3% by mass

As is clear from Table 2, the three-component hair treatment agent of Example 2a, in which sodium carboxymethylcellulose was blended in the first part, was thicker than that in Example 2b, in which sodium carboxymethylcellulose was not blended in the first part. It had excellent feel and gloss. Further, the amount of water-soluble polysaccharide etc. blended in the first agent of Example 2b is larger than the amount of water-soluble polysaccharide etc. blended in the first agent of Example 2a. That is, it is considered that by blending sodium carboxymethyl cellulose as a water-soluble polysaccharide in the first agent together with other water-soluble polysaccharides, etc., the thickness and gloss can be improved with a small amount of blending.

[Examples 3a to 3c]
In Examples 3a to 3c, a three-component hair treatment agent consisting of a pre-treatment agent, a first agent, and a second agent was prepared, and the thickness, smoothness, and gloss were evaluated in the same manner as described above. As a standard for comparison, the three-component hair treatment agent of Example 3c was used. The evaluation results are shown in Table 3.

<Preparation of pretreatment agent>
As the pretreatment agent in Examples 3a to 3c, the same pretreatment agent as in Example 1a was used.

<Preparation of first agent>
The first agents of Examples 3a to 3c were prepared into cream-like dosage forms by blending the raw materials shown in Table 3 below with water. The pH (25°C) of these first agents was in the range of 4.0 to 5.0.

<Preparation of second agent>
The second agent in Examples 3a to 3c was the same as the second agent in Examples 2a and 2b.

As is clear from Table 3, the three-component hair treatment compositions of Examples 3a and 3b had better thickness than the three-component hair treatment composition of Example 3c. From this result, it was found that adding stearoxyhydroxypropyl methylcellulose as a water-soluble polysaccharide or the like to the first agent or adding O-[2-hydroxy-3-(trimethylammonio)propyl]hydroxyethylcellulose chloride gives a thicker effect. It is thought that this will further improve the performance.

Moreover, the three-component hair treatment agent of Example 3b had improved gloss compared to the three-component hair treatment agent of Example 3c. From these results, it was concluded that adding O-[2-hydroxy-3-(trimethylammonio)propyl]hydroxyethylcellulose chloride as a polysaccharide to the first agent improves not only the thickness but also the gloss. Conceivable.
