Description

  The present invention relates to a hair cosmetic that is housed in an aerosol can and discharged from the aerosol can, a hair cosmetic that stores the hair cosmetic in a discharge container, and a method of using the hair cosmetic.

2. Description of the Related Art Conventionally, a hair cosmetic product in which a hair cosmetic agent is stored in an aerosol can and the hair cosmetic agent is discharged from the aerosol can when used is known.
Such hair cosmetic agents are prepared in various dosage forms such as liquid to cream in order to match the cosmetic aspect desired by the user and to provide an appropriate cosmetic effect.

  In addition, when using hair cosmetics, after the hair cosmetic agent is directly discharged onto the hair, the hair cosmetic agent and the hair are combed together with a brush, or the hair cosmetic agent is directly discharged onto the palm, It is generally applied to the hair after spreading it on the palm of the hand and then applying the hair cosmetic to the hair by combing the cosmetic and the hair together using a brush.

  In particular, among hair cosmetics used in aerosol containers, in hair dyes and depigmenting agents, viscous agents such as foams, creams, gels, pastes, etc. are used to enhance the cosmetic effect. It is common to prepare the mold.

  In addition, such hair dyes or depigmenting agents include a single agent type housed in an aerosol can in a state where all the constituent components are mixed, and a first agent containing an oxidation dye intermediate. And a second agent containing an oxidant, and the first and second agents are housed in separate aerosol containers, and are mixed in use when used. ing.

  And when using a single agent type hair dye or decoloring agent, the one that is discharged from the aerosol can onto the tray once, scrubbed with a spatula or brush etc. and applied to the hair for makeup Many. In particular, when using a two-component hair dye or a decoloring agent, the first and second agents are discharged from each aerosol can onto the tray, and then the first and second agents are used with a spatula or a brush. In many cases, it is applied to hair after mixing.

  By the way, in particular, the two-component hair dye allows a colorless low-molecular-weight oxidative dye intermediate to penetrate into the hair fiber and causes oxidative polymerization to occur in the hair fiber, thereby generating a dye base. The dye base is dyed by chemically bonding to the acidic group of the hair fiber. And when using this 2 agent type hair dye, it is common to mix a 1st agent and a 2nd agent just before using.

  However, conventionally, when such a two-component hair dye is used, hair that has been dyed immediately after mixing and hair that has been dyed for some time after mixing (for example, color) It has been known that the density of the image is different.

Therefore, the present inventors have conducted an experiment in which a representative oxidation dye intermediate used in a two-component hair dye is mixed with an oxidation agent, and the remaining amount of the oxidation dye intermediate after mixing is measured. went.
FIG. 8 is a graph showing the experimental results. In FIG. 8, the horizontal axis indicates the elapsed time [minutes] after mixing the oxidation dye intermediate and the oxidizing agent, and the vertical axis indicates the remaining amount of the oxidation dye intermediate after mixing. The ratio of the amount of the oxidized dye intermediate after mixing to the amount of the body is shown in [%].

In this experiment, paraphenylenediamine, paraaminophenol, metaaminophenol, and resorcin were used as the oxidation dye intermediate, and hydrogen peroxide was used as the oxidizing agent.
As a result of experiments, it was found that the remaining amounts of these four kinds of oxidative dye intermediates decreased after mixing, and in particular, 20 to 30% of oxidative dye intermediates decreased within 10 minutes after mixing. did. As described above, the reason why the oxidation dye intermediate decreases after mixing the oxidation dye intermediate and the oxidation agent is that the oxidation dye intermediate rapidly undergoes oxidative polymerization with the oxidation agent.

When such a phenomenon actually occurs during hair dyeing, the shade of color differs at the hair start point and the hair end point (that is, uneven coating occurs).
In particular, when the two-component hair dye has a high viscosity, it is difficult to mix the first and second agents, and there are many operations for mixing these first and second agents. Therefore, at the end of mixing, the oxidative polymerization of the oxidative dye intermediate proceeds, and at the start of hair dyeing, only the hair dyeing ability lower than the original hair dyeing ability can be exhibited. .

  Moreover, in general, not only two-component hair dyes and depigmenting agents are often used which have an irritating odor as a constituent material, and the hair dye is discharged from an aerosol container. If you spend a lot of time applying it, it will be uncomfortable with an irritating odor. Furthermore, in the case of a two-component hair dye or a decoloring agent, if time is spent on the mixing work of the first and second agents, an irritating odor is more unpleasant and uncomfortable.

  In addition, since the two-part decoloring agent contains hydrogen peroxide, if it takes time to discharge and apply, the hydrogen peroxide begins to decompose, which is lower than the original decoloring ability. Only the ability to decolorize can be demonstrated. Furthermore, in the case of a two-component decoloring agent, if time is spent on the mixing work of the first and second agents, hydrogen peroxide is further decomposed, so that the decoloring ability is further reduced.

  This invention is made | formed in view of such a problem, and it aims at improving the operativity of the hair cosmetic agent apply | coated to hair and using it, and enabling it to apply to hair rapidly.

Means for Solving the Problems, Embodiments of the Invention, and Effects of the Invention

  The invention according to claim 1, which has been made to achieve this object, has a stem as a content in a discharge container comprising an aerosol can that can discharge the content from the stem by the pressure of the filled propellant. A hair cosmetic that is stored and discharged from the discharge container, and is characterized by being produced to have a viscosity of 1000 to 100000 cps.

  As described above, hair cosmetics used in hair cosmetics are prepared in various dosage forms according to the purpose of use and the object to be used. For example, typical dosage forms include foam, gel, jelly, paste, cream, and the like.

  And, when the hair cosmetic agent is stored as the contents in a discharge container configured to be able to discharge the stored contents to the outside by the user's operation, in particular, the discharge container composed of an aerosol can, Since it is necessary to easily discharge the hair cosmetic composition to the outside, it is necessary to prepare the hair cosmetic composition so as to have a viscosity that flows moderately.

  When the hair cosmetic agent has a high viscosity, it may become difficult to adhere to the hair when the hair cosmetic agent is applied to the hair, which not only hinders the cosmetic operation, but also the hair cosmetic agent. Will cause uneven coating, which is a state where a portion where the coating is sufficiently applied and a portion where the coating is not applied are mixed.

  Therefore, as described in the present invention (Claim 1), it is desirable to produce a hair cosmetic contained in a discharge container made of an aerosol can within a viscosity range of 1000 to 100000 cps. Thus, when the viscosity of the hair cosmetic is in the range of 1000 to 100000 cps, the hair cosmetic is discharged from the discharge container when the hair cosmetic is stored in a discharge container made of an aerosol can. In addition, the hair cosmetic agent easily adheres to the hair. In addition, the hair cosmetic agent can be smoothly applied to the entire hair region where it is desired to be applied, and can be uniformly applied to the hair, so that the effect of the hair cosmetic agent can be sufficiently exerted without application unevenness. Is possible.

  In particular, a hair cosmetic within a viscosity range of 5000 to 50000 cps does not sag from the brush even when discharged from a discharge container made of an aerosol can onto the brush, and is uniform when the hair cosmetic is applied to the hair. It is possible to obtain a natural hair dyeing effect. Therefore, it is preferable to produce the hair cosmetic agent within a viscosity range of 5000 to 50000 cps.

  By the way, in order to enhance the cosmetic effect of the hair cosmetic agent (for example, the hair dyeing effect, the decoloring effect, etc.), the hair cosmetic agent according to claim 1 is made of an alkaline agent and an oxidation dye as described in claim 2. It comprises a first agent containing at least one and a second agent containing an oxidizing agent. When using a hair cosmetic, the first agent and the second agent are mixed with each other. It is good.

  And as a composition which comprises the 1st agent in case hair cosmetics are hair dyes, p-toluylenediamine, p-phenylenediamine, p-methylaminophenol, 4-nitro-o-phenylenediamine, 1 -Amino-4-methylanthraquinone, polyoxyethylene (9) lauryl ether, polyoxyethylene (15) nonylphenyl ether, polyoxyethylene (5.5) cetyl ether, polyoxyethylene (20) cetyl ether, stearyl trimethyl chloride Ammonium, sodium cetyl sulfate, cetyltrimethylammonium bromide, quaternary nitrogen-containing cellulose ether, cetyl alcohol, cetanol, petrolatum, stearic acid, propylene glycol, hydroxyethyl cellulose, hydroxyethyl cellulose hydroxypro Le trimethylammonium chloride ether, edetate disodium, ascorbic acid, sodium sulfite anhydrous, EDTA sodium, can be used 28% ammonia water and monoethanolamine, the purified water and the like.

  On the other hand, as a composition constituting the second agent in the case of a hair dye, hydrogen peroxide solution, phenacetin, 1-hydroxyethane-1,1-diphosphonic acid, 1-hydroxyethane-1,1-diphosphonic acid tetra Use sodium, cetanol, dimethylpolysiloxane, polyoxyethylene alkyl ether, glycerin, polyethylene glycol 400, polyoxylene (2) nonylphenyl ether, polyoxylene (15) cetyl ether, sodium lauryl sulfate, hydroxyethyl cellulose, purified water, etc. Can do.

And when a hair cosmetic is a decoloring agent, what is necessary is just to abbreviate | omit the dye component in the above-mentioned hair dye composition, You may produce | generate as shown below for a 1st, 2nd agent.
That is, as a composition constituting the first agent in the case of a decolorizing agent, isopropal, polyoxyethylene octyl phenyl ether, isostearic acid, polyoxyethylene oleyl ether, propylene glycol, keratin protein hydrolysate, sodium pyrrolidone carboxylate Ammonia water, ion-exchanged water, or the like can be used.

  In addition, as a composition constituting the second agent in the case of a decolorizing agent, hydrogen peroxide solution, phosphate buffer, methyl paraben, sodium stannate, liquid paraffin, stearyl alcohol, sodium lauryl sulfate, polyoxyethylene cetyl ether, Ion exchange water or the like can be used.

Furthermore, regardless of whether the hair cosmetic is a hair dye composition or a decoloring composition, a thickener, a fragrance, or the like may be added as necessary.
And as an oxidizing agent, you may use the well-known thing containing hydrogen peroxide solution, urea peroxide, etc. Furthermore, stabilizers such as fesenatin and EDTA, surfactants, fats and oils, higher alcohols, acids, pH adjusters and the like may be appropriately added to the oxidizing agent as necessary.

In addition, it is good to use the tin or aluminum which has the property strong against corrosion as a forming material of the aerosol can which accommodates the hair cosmetics which consist of such a composition.
By the way, as described above, in the two-component hair cosmetic, if it takes time to mix the first and second agents, the oxidative polymerization of the added compositions proceeds. However, when the hair cosmetic agent is applied to the hair, the cosmetic ability of the hair cosmetic agent (for example, hair dyeing ability, decoloring ability, etc.) is lowered, and the effect of the hair cosmetic agent cannot be fully exhibited.

  And even if it is in the range of the viscosity of 1000-100,000 cps also in a 2 agent type hair cosmetic, it is possible to mix a 1st, 2nd agent rapidly, Especially, the viscosity of 5000-50000 cps, respectively. Within the range, it is possible to mix more rapidly, and it is preferable to apply the hair cosmetic agent to the hair because a uniform hair dyeing effect can be obtained.

  In order to mix the first and second agents even more quickly, the first and second agents are each in the range of 1000 to 100,000 cps in viscosity, and as described in claim 3, If the viscosity of one agent is a and the viscosity of the second agent is b, the first and second agents may be configured so that the viscosity ratio a: b is in the range of 1: 7 to 7: 1. . In particular, the mixing property is best when the viscosity ratio a: b is in the range of 1: 3 to 3: 1. In this way, it is possible to reduce the time spent for the mixing work.

  Then, as described in claim 4, a cationic compound may be added to the first agent, and an anionic compound may be added to the second agent. When the first and second agents configured in this way are mixed, the cationic compound and the anionic compound begin to ionically bond with each other, and finally form a complex and stabilize. At that time, if an oxidative dye intermediate or an oxidant is present around the cationic or anionic compound, the first and second agents other than the cationic and anionic compounds are accompanied by the movement of the cationic and anionic compounds. These compositions are attracted to these cationic and anionic compounds, and finally the first and second agents are mixed with each other. Therefore, according to the present invention (Claim 4), the first and second agents are easily mixed and can be quickly applied to the hair.

  In addition, if the first agent and the second agent are produced so that the compounding ratio of the cationic compound and the anionic compound is within the range of 50: 1 to 1:50, the ionic bond is rapidly performed. 1 and 2 agents can be mixed more rapidly. And it is desirable for the compounding quantity of the cationic compound added to a 1st agent to be 0.1-20 weight% with respect to the whole 1st, 2nd agent. On the other hand, the compounding amount of the anionic compound added to the second agent is desirably 0.1 to 20% by weight with respect to the entire first and second agents.

  The same effect is observed when an anionic compound is added to the first agent and a cationic compound is added to the second agent, but when hydrogen peroxide and the cationic compound coexist, corrosion of the aerosol can can be promoted. This is not preferable because of its nature.

Examples of cationic compounds and anionic compounds that can be used in hair cosmetics are shown below.

  In addition, as a commercial item, Junron PW series, Rheojic series (Nippon Pure Chemicals), Carbopol series, PEMULEN series, ETD series (BF Goodrich) etc. are mentioned.

  When the hair cosmetic is a hair dye, the hair dye composition includes paraphenylenediamine, paratoluylenediamine, N, N-bis (2-hydroxyethyl) -p-phenylenediamine, p-amino. Phenol, p-amino-o-cresol, 4,4′-diaminodiphenylamine, 2-chloro-p-phenylenediamine, p-methylaminophenol, m-aminophenol, hydroquinone, resorcin, o-aminophenol, phloroglucin, 2 -Nitro-p-phenylenediamine, 4-nitro-o-phenylenediamine, catechol, pyrogallol, N-phenyl-p-phenylenediamine, 1,4-diaminoanthraquinone, 2,4-diaminophenoxyethanol, 5- (2-hydroxy Ethylamino) -2-methylphenol And it may be added a component selected from the salts thereof. These hair dye compositions are suitable because they are excellent in hair dyeability.

The salt is, for example, an organic acid salt or an inorganic acid salt, that is, sulfate, hydrochloride, phosphate, acetate, propionate, lactate, citrate and the like, and is not particularly limited.
By the way, in order to generally distribute the hair cosmetic composition according to claim 1 as a hair cosmetic product, it has a stem as described in claim 5 and the contents are discharged from the stem by the pressure of the filled propellant. A possible aerosol can, an operation member for pressing the stem of the aerosol can from the outside, and a discharge member for discharging the contents discharged from the stem by pressing the operation member to the outside What is necessary is just to store the said hair cosmetics as a content in the provided discharge container.

  In such a discharge container, when the stem is pushed down as the operating member is pressed, the hair cosmetic agent in the storage container is discharged from the stem by the pressure of the filled propellant, and further discharged from the nozzle. Anyone from young to elderly can easily operate.

  In the case of the two-component hair cosmetic composition according to claims 2 to 4, the first and second agents can be stored independently in the discharge container according to claim 5. And when using the 2 agent type hair cosmetics accommodated in the independent discharge container, if it mixes and discharges from each discharge container, it can apply | coat to hair rapidly.

  In particular, in order to generally distribute the two-component hair cosmetic composition according to claims 2 to 4 as a hair cosmetic product, as described in claim 6, the two-pack cosmetic composition has a stem and is pressurized by the pressure of the filled propellant. A pair of aerosol cans capable of discharging contents from the stem, a connecting member for connecting the pair of aerosol cans to each other, an operation member for simultaneously pressing the stem of the pair of aerosol cans from the outside, and It is desirable to store the hair cosmetic as the contents in a simultaneous discharge container provided with a discharge member for discharging the contents discharged from each stem to the outside by pressing the operation member.

  Thus, in the simultaneous discharge container according to claim 6, when the stem is pushed down as the operating member is pressed, the hair cosmetic in the first and second aerosol cans is caused by the pressure of the filled propellant. Are discharged from each stem and further discharged from the nozzle in a merged state. And the operation of the simultaneous discharge container can not only obtain the same effect as the discharge container according to claim 5, but also can eliminate the work of mixing the first and second agents, It can be applied quickly to hair.

  Further, as described in claim 7, when the inner bag is provided inside the aerosol can and the hair cosmetic agent is stored in the inner bag, the filled propellant and the hair cosmetic agent do not mix with each other. The hair cosmetic agent can be prevented from being altered. In addition, when the aerosol can is filled with a propellant having a high pressure, the entire inner bag can be pressed at a high pressure, so that the hair cosmetic contained in the inner bag can be discharged without any leakage. Therefore, all the hair cosmetics can be used up without waste.

  In addition, nitrogen gas, liquefied petroleum gas, dimethyl ether, etc. can be used as a propellant. And it is preferable to use nitrogen gas which has an inert property from the point which does not have a bad influence on the hair cosmetics accommodated in the inner bag.

  On the other hand, the constituent material of the inner bag is preferably a deformable material, for example, high density polyethylene (HDPE), low density polyethylene (LDPE), linear low density polyethylene (LLDPE), ethylene / vinyl acetate copolymer. Saponified materials (EVOH), polyacrylonitrile, polyethylene terephthalate (PET), polypropylene, vinyl, nylon, and other synthetic resins, and laminates thereof can be used.

  Further, in particular, as the inner bag for storing the first agent, aluminum whose inner surface is coated with epoxy phenol resin, epoxy urea resin, epoxy amino resin or epoxy amine resin (hereinafter referred to as inner surface coated aluminum) may be used. In particular, it is preferable to use LDPE or LLDPE because the remaining amount of contents stored in the inner bag can be reduced.

  On the other hand, as the inner bag for storing the second agent, similarly to the inner bag for storing the first agent, when LDPE or LLDPE is used, the remaining amount of the contents stored in the inner bag can be reduced. Therefore, it is preferable.

  In order to prevent corrosion of the storage container due to the first agent, the inner surface of the storage container storing the first agent is a single coat, double coat of epoxy phenol resin, epoxy urea resin, epoxy amino resin, epoxy amine resin, or It is better to paint with a triple coat.

In order to prevent corrosion of the storage container due to the second agent, it is most preferable in terms of chemical resistance that the inner surface of the storage container storing the second agent is coated with a polyamide-imide resin.
In particular, in the two-component hair cosmetic described above, the hair cosmetic is stored in a discharge container configured to be discharged to the outside, and the hair cosmetic is applied when the hair cosmetic is applied to the hair. Various usage methods are conceivable, such as discharging from a discharge container onto a mixing tray and mixing and applying to hair using a brush.

  However, when using it, discharging and mixing on the tray one by one not only makes the mixing work complicated, but also spends time on the mixing work. May cause decline. In addition, a plurality of work tools such as a tray and a mixing madra are required for the mixing operation.

  Therefore, as described in claim 8, it is desirable to directly discharge the hair cosmetic agent onto the application brush and comb the hair with the brush in this state. By doing in this way, a hair cosmetic agent can be apply | coated to hair rapidly and it becomes possible to perform a hair dyeing | staining operation | work smoothly. Moreover, since the hair cosmetic agent is simply sprinkled onto the brush to comb the hair, there is no complicated work and anyone from the young to the elderly can easily do it.

  As described above, the direct discharge onto the brush is not limited to the two-component hair cosmetic, and may be performed with a single-component or multiple-mixed-type hair cosmetic such as a three-component type. . Even in this case, the same effect as that of the two-pack type hair cosmetic product can be obtained.

  Further, in the present invention (Claim 8), since it is not necessary to use a working tool such as a mixing tray or a brush other than the brush, the user can prepare such work tools and perform operations such as cleaning after use. This is convenient because it is no longer necessary. Moreover, since it becomes unnecessary for the hair cosmetic manufacturer to attach a working tool other than the brush, the cost of the hair cosmetic product can be reduced.

In order to prevent the hair cosmetic from adhering to the hand during operation, it is preferable to wear a synthetic resin glove.
In addition, various types of brushes can be used. For example, brush teeth are implanted at an appropriate interval at the end of a base for implanting brush teeth (hereinafter referred to as a brush base). If the hair cosmetic agent is discharged to the central region of the brush base surrounded by the brush teeth, the brush teeth can prevent the discharged hair cosmetic agent from dripping from the brush. Furthermore, if a plurality of protrusions are provided in the region surrounded by the brush teeth on the brush base, the hair cosmetic agent adheres to the brush teeth, so that the hair cosmetic agent can be further prevented from dripping. It becomes.

  When a hair cosmetic agent in the viscosity range (1000 to 100,000 cps) as described in claim 1 is discharged onto a commonly used synthetic resin brush, the hair cosmetic agent is less likely to remain on the brush. Almost all of the hair cosmetic agent on the brush can be attached to the hair. In addition, since the hair cosmetic agent is less likely to remain on the brush, the newly ejected hair cosmetic agent and the previously ejected hair cosmetic agent are not mixed, thereby preventing the occurrence of uneven coating. It becomes possible.

  And when using the hair cosmetic which consists of a discharge container of Claim 6, since it can discharge on a brush in the substantially mixed state, if hair is combed with the brush, hair will be promptly A hair cosmetic agent can be applied to the skin. Therefore, the hair dyeing operation can be performed more smoothly.

Hereinafter, each embodiment embodying the present invention will be described.

As shown in FIG. 5, when the hair dyeing operation is performed using the discharge container 2 in the first embodiment and the simultaneous discharge container 20 in the second to fifth embodiments, the dyeing is performed directly from the discharge containers 2 and 20 on the brush. The hair was discharged and applied with a brush to the hair bundle or hair to be dyed. In Comparative Example 2, the hair dye was directly discharged from the tube onto the brush and applied to the hair bundle or hair to be dyed by brushing with the brush.

  FIG. 6 is an explanatory diagram (a front view, a left side view, and a right side view) showing a schematic configuration of a brush used in Examples 1 to 5 and Comparative Example 2. As shown in the front view in FIG. 6, the brush includes a brush portion that functions as a brush, a comb portion that functions as a comb, and a gripping portion that is held by a user. As shown in the left side view in FIG. 6, the brush portion includes a brush base having a flat surface, a plurality of fine hairs that are thin brush teeth provided at both ends of the brush base, and a center of the brush base. And a protrusion provided on the surface. In Examples 1 to 5 and Comparative Example 2, the hair dye is discharged onto the central region of the brush portion and applied to the hair bundle or hair. Further, the protrusion is, for example, such that the top is rounded and the whole has a spatula shape. Providing such protrusions is preferable because it is possible to prevent the hair dye from dripping.

  On the other hand, as shown in the right side view in FIG. 6, the comb portion is composed of a plurality of comb teeth. In addition, the gripping portion is composed of a gripping portion that is gripped by the user and a support portion that supports the brush portion and the comb portion (in the comb portion, the support portion is used for implanting a plurality of comb teeth. Used). In Examples 1 to 5 and Comparative Example 2, after applying the hair dye to the hair bundle or hair to be dyed with the brush part, the hair dye is extended to the whole hair bundle or hair. If it combs at a comb part, it will become possible to extend a hair dye uniformly. However, in the case of hair, particularly when it is necessary to apply partially, such as at the hairline, it is possible to uniformly extend the hair dye simply by using the brush portion.

  Moreover, the tube which accommodates the 1st agent used in the comparative example 2 is a tube which the base material consists of aluminum, and the inner surface was coat | covered with the epoxy phenol resin. Moreover, the tube which accommodates a 2nd agent is a double tube which put the inner tube made from synthetic resins, such as polyethylene, in the outer tube made from aluminum.

Next, hair dyeing operation was performed based on the contents shown in Tables 3 and 4 using the hair cosmetics prepared in the contents of Examples 1 to 5 and Comparative Examples 1 to 3 described above.
And according to the reference | standard shown below, the uniformity of the hair dye in each Examples 1-5 and each comparative example and the irritating odor at the time of operation were evaluated. In addition, about the uniformity of hair dyeing, it carried out about two kinds, the hair bundle prepared for experiment, and the paneler's hair actually.

First, the method of hair dyeing operation and evaluation criteria will be described below.
(1) Evaluation of hair dyeing uniformity A (hair bundle hair dyeing test)
A mixed hair bundle of human black hair and white hair (weight: about 2 g, gray hair: about 30%) was washed with 5 g of 5 wt% sodium lauryl sulfate and further rinsed with warm water.

And the moisture was wiped off from the mixed hair in the wet state, the hair dye composition was applied to the hair bundle with the contents of Examples 1 to 5 and Comparative Examples 1 to 3, and left in a thermostatic chamber (37 ° C.). .
In the hair dyeing operation using the brush coating in Comparative Examples 1 and 3, first, the first and second agents were taken out from the respective storage containers onto the mixing tray and mixed, and the hair dye composition immediately after mixing was about 2 g was applied to the hair bundle, and 10 minutes after mixing, about 2 g of the hair dye composition was applied to another hair bundle. And 30 minutes after mixing, both hair bundles were washed with water and evaluated.

  The reason for setting the interval of 10 minutes is that the time required for the hair dyeing operation in actual use is about 10 minutes, and the difference in the hair dyeing result between the part first applied and the part applied last is shown. This is to confirm.

  In the hair dyeing operation using the brush coatings a and b in Examples 1 to 5 and Comparative Example 2, two brushes were prepared for each Example and each Comparative Example, and the first and second agents in brush coating were prepared. About 1 g of each of the first and second agents was placed on each brush at the same time as the mixing time. That is, the first and second agents were applied to the hair bundle with a brush immediately after placing the first and second agents. Next, after the elapse of 10 minutes, the first and second agents were applied to the hair bundle with another brush on which the first and second agents were placed. Then, after 30 minutes had passed since the first and second agents were placed on the first brush, all the hair bundles were washed with water and evaluated.

  In the brush coating a, the first and second agents are brushed from containers (Example 1, Comparative Example 3: discharge container, Comparative Examples 1, 2: tube) separately containing the first and second agents, respectively. It is to be placed on top. In the brush coating b, a simultaneous discharge container is used, and the first and second agents are mixed and placed on the brush.

The hair bundle after dyeing was subjected to sensory evaluation by 10 professional panelists based on the following evaluation criteria.
(Evaluation criteria)

△ ... 4-5 people
It was evaluated that “there was no coating unevenness and the entire surface was uniform”.

× ... 3 or less
It was evaluated that “there was no coating unevenness and the entire surface was uniform”.
(3) Evaluation of irritating odor Evaluation of hair color uniformity The subject (female model) who dyed hair in B was interviewed and evaluated for the presence or absence of irritating odor during hair dyeing.

Evaluation Criteria A: Four or more of the five test subjects evaluated that no pungent odor was felt.
A: Three of the five test subjects evaluated that they did not feel a pungent odor.

Δ: Two of the five test subjects were evaluated as having no irritating odor.
X: It was evaluated that 1 or less of 5 subjects each did not feel an irritating odor.

  And the evaluation result of each Examples 1-5 and Comparative Examples 1-3 is shown in Table 3 and Table 4.

As is clear from the above results, it was found that Examples 2 and 3 had the best hair dyeing operability. Moreover, it turned out that Examples 1-5 are more excellent in hair dyeing operability than any of Comparative Examples 1-3.
(Examples 6 to 8)
Next, based on the formulation examples of the first and second agents shown below, a cationic compound is added to the first agent based on the contents of Examples 6 to 8 shown in Tables 5 to 7, and The anionic compound was added to the second agent. And the 1st, 2nd agent was accommodated in the simultaneous discharge container, these 1st, 2nd agents were discharged on the brush, and the hair dyeing operation was performed by the method similar to evaluation B of hair dye uniformity. .
