Description

  The present invention relates to a hair dye and a hair dyeing method. More specifically, the present invention is a multi-component hair dye comprising a first agent containing an alkaline agent and a second agent containing an oxidizing agent, wherein the viscous liquid mixture of each agent is applied to the hair. The present invention relates to a hair dye that can be foamed on hair after application, and can also be subjected to hair treatment as it is after application to hair, and a hair dyeing method that uses this hair dye.

  2. Description of the Related Art Conventionally, hair dyes such as oxidative hair dyes, hair depigmenting agents, hair depigmenting agents, etc., and viscous liquids such as cream and gel are provided. These hair dyes are general ones, and are usually configured in a multi-part type such as a two-part type or a three-part type containing a first agent containing an alkaline agent and a second agent containing an oxidizing agent. The mixture of each agent is applied to the hair using a comb, a brush, or the like to perform hair dyeing.

  Since such a hair dye has a high viscosity, for example, dripping of the liquid during a hair dyeing treatment time of about 30 minutes can be effectively prevented, but it is difficult to apply it uniformly to the entire hair. In particular, it is difficult for the user's own back of the head or the like to uniformly apply the hair dye even if a mirror is used. Therefore, when a viscous liquid hair dye is used for the entire hair dyeing, undyed or uneven dyeing tends to occur. In that sense, it can be said that the viscous liquid hair dye is a hair dye suitable for partial dyeing of a specific part such as the root part or hairline of the hair.

  In contrast, for example, as disclosed in Patent Document 1 and Patent Document 2 below, a mixture of each agent of a multi-component hair dye is discharged in a foam form with an aerosol-type or non-aerosol-type former container. Foam hair dyes for application to the hair are also provided. With these hair dyes, it is possible to evenly spread the entire hair by swallowing the discharged foam by hand. Therefore, it can be said that it is a hair dye suitable for whole hair dyeing.

  Further, for example, as disclosed in Patent Document 3 below, a hair dye is applied to the hair and then foamed on the hair to perform a hair dyeing process. Further, in Patent Document 4 below, a multi-component hair dye composition is impregnated into a structure containing a flexible porous material such as a sponge and foamed so as to hold the sponge or the like. The hair dyeing method applied to is disclosed. According to these hair dyes, hair can be dyed by using the hair dye as a foam without using a former container.

(First problem of the prior art)
By the way, although the foam-like hair dye using the former container disclosed in Patent Document 1 and Patent Document 2 is a hair dye suitable for the whole hair dyeing, it mixes each agent of the hair dye and foams. For this reason, a former container is required to discharge the liquid in a shape, and an increase in cost is unavoidable.

  On the other hand, the hair dye disclosed in Patent Document 3 and the like does not require a foam container because it is foamed after application to the hair, but good generation of foam when the hair dye is foamed on the hair, It cannot be said that good foam quality is fully considered.

  As described in paragraph 0003, the invention of Patent Document 4 is based on the recognition that “the method of foaming hair dye on the hair is difficult to realize due to problems of dripping and foaming”. . However, the problem-solving means is a detour method in which a sponge impregnated with a hair dye is swollen and applied to the hair, which requires a separate lathering tool and is troublesome and efficient. bad.

  That is, the conventional hair dyes according to Patent Documents 1 to 4 are costly or troublesome in that they require a former container or a foaming tool to replace it, even when those tools are not required, Foaming and foam quality are not fully considered.

(Second problem of the prior art)
Conventional viscose hair dyes such as creams and gels are not supposed to be foamed and applied to the hair, and of course are not designed to contain ingredients that can ensure foaming.

  On the contrary, the hair dyes according to Patent Documents 1 to 4 are applied to hair as a foam. In Patent Document 4, there is a description in paragraph 0008 that “can be applied to both partial dyeing and full-head dyeing”, but this is “a foamy hair dye that can be applied to both partial and full-head dyeing. Is simply written in the sense of "." Accordingly, the hair dyes according to Patent Documents 1 to 4 are not scheduled to be subjected to the hair dyeing process without foaming after being applied to the hair, and of course, suitable for such use. Viscosity is not considered.

  Hair dyes that are foamed after being applied to hair (hereinafter, hair dyes used for this purpose are also referred to as “hair-like hair dyes”) may have a certain viscosity. Is sufficient if it can be prevented from dripping in a very short time after being applied to the hair until it is foamed. On the other hand, in general hair dyes such as ordinary creams and gels (hereinafter, hair dyes used for this purpose are also referred to as “hair dyes for mucous use”), for example, about 30 minutes. It is necessary to prevent dripping over a relatively long hair dyeing time. That is, the required level of viscosity is clearly different between a foamy hair dye and a viscous liquid hair dye.

  By the way, in many cases, a viscous hair dye suitable for partial dyeing and a foamy hair dye suitable for whole dyeing are used in relation to each other. For example, for specific hair dyeing occasions, the entire hair is dyed using a foamy hair dye, and for the next hair dyeing occasion, the root part of the hair is partially dyed using a viscous liquid hair dye. Sometimes you just want to do it.

  In such a case, it is a single hair dye that can be suitably used as a hair dye for foamy use for whole dyeing, or as a hair dye for viscous liquid use for partial dyeing. If there is a good hair dye of “2WAY type”, it is very easy to prepare a single hair dye as compared with the case of preparing a hair dye for each of those uses. Convenient and economical.

  However, as pointed out in paragraph 0003 of the above-mentioned Patent Document 4, such a hair dye has a high viscosity that does not cause dripping over a hair dyeing treatment time of about 30 minutes when applied to hair. Even with such a high viscosity, when foaming on the hair, there is a difficult requirement to produce a foam with good foam quality. Furthermore, it is necessary to avoid the problem that the compounding ingredients for meeting such demands exhibit an antifoaming action or deteriorate the foam quality. A 2-way hair dye that can meet such demands has not yet been provided.

(Problem of the present invention)
Therefore, the present invention is a multi-component hair dye (a hair dye for foamy use) that applies a viscous liquid mixture of each agent to the hair, and then foams the hair on the hair and performs a hair dyeing treatment. Providing what ensures good foam quality is a first problem to be solved.

  Further, the present invention is a multi-component hair dye as described above, and can also be subjected to a hair dyeing process after applying the viscous liquid mixture of each agent to the hair (hair dye for mucus use), In this case, providing a device that does not cause dripping of liquid is a second problem to be solved.

  Furthermore, the present invention is a two-way hair dyeing that can be used by using these multi-component hair dyes, and used as a foamy hair dye and as a viscous liquid hair dye. Providing a method is a third problem to be solved.

A hair dye that contains the following components (A) and (B), and the mass ratio B / A of the contents of these two components is in the range of 0.1 to 3: It is.

Component (A): 1 to 10% by mass of an ionic surfactant (however, higher fatty acids other than lauric acid, myristic acid and salts thereof and salts thereof are excluded from component (A)).
Component (B): Higher alcohol (Structure of the second invention)
The constitution of the second invention of the present application for solving the above-described problem is that the hair dye according to the first invention is used for one or both of the following (1) and (2) hair dyeing treatments. It is.

  (1) After applying the viscous liquid mixture of the above-mentioned agents to the hair, the hair is foamed on the hair to perform a hair dyeing treatment.

  (2) After applying the viscous mixture of each agent to the hair, the hair dyeing treatment is performed as it is.

The constitution of the fourth invention of the present application for solving the above problem is a hair dye in which the hair dye according to any one of the first to third inventions further contains the following component (C).

  (C) At least one selected from a sugar-based nonionic surfactant, a nonionic surfactant having an HLB of 12 or more and less than 20, and a nonionic surfactant that is an amide compound.

  In this fourth invention, “HLB” is an abbreviation of Hydrophilo-Lipophile Balance, which generally indicates the relative strength between hydrophilicity and lipophilicity of a surfactant molecule. The higher the HLB value, the stronger the hydrophilicity, and the smaller the HLB value, the more lipophilic. The HLB value is calculated from the well-known Griffin equation.

(Structure of the fifth invention)
The structure of the fifth invention of the present application for solving the above-mentioned problems is the use of the hair dye according to any one of the first to fourth inventions, and one or both of the following (3) and (4): This is a hair dyeing method.

  (3) After applying the viscous liquid mixture of each agent of the hair dye to the hair, the hair is foamed on the hair to perform the hair dyeing treatment.

  (4) After applying the viscous liquid mixture of each agent of the hair dye to the hair, the hair dyeing treatment is performed as it is.

  The multi-component hair dye of the first invention can be applied to the hair after applying the viscous mixture of the respective agents to the hair, and can be subjected to hair dyeing treatment on the hair. Goodness is ensured. The reason for this is that 1 to 10% by mass of an ionic surfactant excluding a specific higher fatty acid and the like is blended as the component (A), a higher alcohol is blended as the component (B), and the components (A) and (B) It exists in the point which is making mass ratio B / A of content of a component into the range of 0.1-3.

  The component (A) is mainly responsible for good foaming and the viscosity of the foam and viscous mixture. When the blending amount of the component (A) is less than 1% by mass, good foaming cannot be obtained, and when the blending amount exceeds 10% by mass, sufficient viscosity cannot be obtained.

  In addition, even if it mixes with a nonionic surfactant instead of (A) component, said effect is not ensured. In addition, among the higher fatty acids that are one kind of ionic surfactants, higher effects other than lauric acid, myristic acid and their salts, and salts thereof may be blended in place of the component (A), and the above effects Is not secured.

  The component (B) is mainly involved in the viscosity of the viscous liquid mixture of each agent, but also exhibits a certain defoaming action. By blending the component (B), a suitable viscosity as a hair dye for a viscous liquid is realized without impairing the characteristics as a hair dye for foamy use. The absolute value of the blending amount of the component (B) does not directly affect the effect of the present invention, but the mass ratio B / A of the content of the component (B) to the component (A) affects the effect of the present invention. . That is, when the mass ratio B / A is less than 0.1, a sufficient viscosity cannot be obtained, and the liquid dripping is applied when the viscous liquid mixture of each agent is applied to the hair and used as a hair dye for the viscous liquid application. Cause a fall. When the mass ratio B / A exceeds 3, good foam quality when used as a hair dye for foamy use cannot be obtained due to the defoaming action of the component (B).

[First agent and second agent of oxidative hair dye]
The first agent of the oxidative hair dye according to Examples 1 to 5 shown in the last Table 1 and the second agent of the oxidative hair dye according to Examples 1 to 9 shown in the last Table 2 were prepared. Among the component names of the first agent shown in Table 1, “myristic acid K” is a potassium salt of myristic acid. These 1st agent and 2nd agent were prepared in cream form or gel form according to the conventional method. In Tables 1 and 2, the unit of the numerical value indicating the composition of the component is “mass%”, but these numerical values are the mass% number in the first agent or the second agent, and are the first agent and the second agent. It is not the mass% number at the time of mixing.

[Oxidative hair dye according to Examples and Comparative Examples]
From the first agent according to Examples 1 to 5 shown in Table 1 and the second agent according to Examples 1 to 9 shown in Table 2, in the columns of “First Agent” and “Second Agent” in Table 3 By selecting and combining the first agent and the second agent according to the specific example numbers shown respectively, the two-component oxidative dyeing shown in Table 1 Examples 1 to 8 and Comparative Examples 1 to 5 A hair was made up. About these Examples and Comparative Examples, as described below, the content (mass%) of the component (A) in the mixed solution when mixed at a mass ratio of the first agent: second agent = 1: 3 is shown. 3 in the column “A”, the content (mass%) of the component (B) in the column “B” in Table 3, and the mass ratio B / A of both contents in “B / A” in Table 3. In each column.

[Evaluation of Oxidative Hair Dye According to Examples and Comparative Examples]
(Evaluation of difficulty of dripping)
About the oxidative hair dye shown in Examples 1 to 8 and Comparative Examples 1 to 5, 1 part by mass of each first part and 3 parts by weight of the second part are mixed to form a cream or gel. The same amount of each mixture was uniformly applied to the wig for evaluation. Then, over 30 minutes after application under the condition of 40 ° C., the difficulty of dripping from the wig was observed over time and evaluated. Therefore, this evaluation is an evaluation in the case where an oxidative hair dye is used as a hair dye for a viscous liquid application.

  The evaluation results were ranked in 8 levels. That is, the evaluation in the case of “the cream or gel did not flow on the hair during standing, and no dripping was seen” was “◎”, “the cream or gel flowed slightly on the hair while standing, The evaluation when “no dripping was seen” was “◎ to ○”, “the cream or gel was flowing on the hair while it was left, but no dripping was seen”, the evaluation was “○”, “ The evaluation when the cream or gel dripped slightly within 30 minutes is “○ to Δ”, the evaluation when the cream or gel dripping within 30 minutes is “△”, “within 15 minutes” Evaluation when “cream or gel dripped” is “△ ˜ ×”, evaluation is “x” when “cream or gel dripped within 5 minutes”, “cream or gel dripped immediately after application” "" Was evaluated as "XX".

  The evaluation results of the difficulty of dripping about the oxidative hair dyes according to Examples 1 to 8 and Comparative Examples 1 to 5 are shown in the “Liquid Drip” column of Table 3.

(Evaluation of foam quality)
About the oxidation hair dye shown in Examples 1 to 8 and Comparative Examples 1 to 5, the first agent and the second agent prepared at the same mass ratio as in the case of the above-mentioned “evaluation of difficulty of dripping”. The same amount of each mixture was uniformly applied to an evaluation wig. Immediately, it was swallowed and foamed on the wig. The foam quality was evaluated by observing the fineness and bulkiness of the foam. Therefore, this evaluation is an evaluation in the case of using an oxidative hair dye as a hair dye for foamy use.

  The evaluation results were ranked in 8 levels. That is, the evaluation when “very easy to foam and bubbles do not disappear at all” is “◎”, and the evaluation when “very easy to foam and bubbles hardly disappear. “O”, “Easily foaming, bubbles hardly disappear”, “O”, “Easily foaming, bubbles disappear slightly, or slightly foaming, bubbles hardly disappear” ”,“ Slightly less foaming, foam disappears slightly ”as“ △ ”,“ Slightly less foaming, foam disappears, or foam hardly disappears, foam disappears slightly ”,“ △-× ”, The evaluation when “it is difficult to foam and the foam disappears” was “X”, and the evaluation when “no bubble” was “XX”.

  The foam quality evaluation results for the oxidative hair dyes according to Examples 1 to 8 and Comparative Examples 1 to 5 are shown in the column “Foam quality” in Table 3. Assuming that stearic acid, which is a higher fatty acid, is included in the component (A), the content of the component (A) in the mixed solution of 1 agent / 2 agents according to Comparative Example 5 is 1.325% by mass, and the mass ratio A / B This value also corresponds to the embodiment of the present invention. However, in reality, stearic acid is not the component (A) of the present invention, and the evaluation of “foam quality” is greatly inferior in the evaluation results.

  According to the present invention, it is possible to provide a hair dye which ensures good foaming and good foam quality as a hair dye for foamy use and does not cause dripping of liquid even as a hair dye for mucous use.
