Description

Hair dye and hair dyeing method

The present invention relates to a hair dye and a hair dyeing method. More specifically, the present invention relates to a multi-component hair dye comprising a first agent containing an alkaline agent and a second agent containing an oxidizing agent, and a viscous liquid mixture of each agent of the hair dye. The present invention relates to a hair dyeing method in which hair is applied to the hair to perform hair dyeing treatment.

Conventionally, it is composed of a first agent containing an alkali agent and a second agent containing an oxidizing agent, and is composed of a multi-component type, and a viscous liquid mixture such as cream, gel or emulsion of each agent is combed or brushed. A hair dye that is applied to the hair using a hair color treatment and the like is provided.

Since such a hair dye has a high viscosity, for example, it is possible to effectively prevent the hair dye from dripping during the hair treatment time of about 30 minutes, 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 to perform a uniform application operation of the hair dye even if a mirror is used. Therefore, when applying a viscous liquid hair dye to the whole hair dyeing, it is easy to produce a partial dye residue and a non-uniform hair dyeing state.

On the other hand, various types of hair dyes have also been proposed in which a mixture of hair dye agents is applied to hair as a foam. Foam hair dyes are easy to distribute evenly throughout the hair. Therefore, it is suitable for the whole hair dyeing, and it is possible to avoid partial dyeing residue and uneven hair coloring.

For example, Patent Documents 1 to 4 listed below disclose foam-like hair dyes that are applied to hair by discharging a mixture of hair dye agents in a foam form using an aerosol-type or non-aerosol-type former container. Has been. However, these foam-like hair dyes require a former container in order to mix each of the hair dyes and discharge them in the form of foam. Therefore, the cost increase for that is inevitable.

Patent Document 5 below discloses a hair dyeing method in which a multi-component hair dye composition is impregnated into a soft sponge and foamed so as to rub the sponge, and the foam hair dye is applied to the hair. Yes. However, the dyeing method of Patent Document 5 is a cumbersome and inefficient method because it is a round method in which a hair dye is foamed using a sponge and then applied to the hair.

Apart from the foamy hair dye described above, for example, the oxidized hair dye disclosed in Patent Document 6 below, after applying to the hair, lathering by hand on the hair and performing the hair dyeing treatment Hair dyes have been proposed. Since this hair dye does not require a foaming container such as a foam container or a sponge, it is possible to avoid the above-described cost increase and trouble in use.

JP-A-9-136818 Japanese Patent Laid-Open No. 10-287534 JP 2007-291015 A JP 2008-291020 A JP 2010-215576 A Japanese Patent Laid-Open No. 9-278637

By the way, the type of hair dye that is foamed and applied to the hair requires not only good foaming but also good foam retention. “Foam retention” refers to suppressing defoaming and maintaining a good foaming state throughout the hair dyeing treatment time.
The hair dyes disclosed in Patent Documents 1 to 5 use a foaming device such as a former container, and thus easily meet such requirements. However, in the type of hair dye that foams on the hair, it is required to show good foaming and foam retention by lathering with a hand on the hair. The hair dye disclosed in Patent Document 6 does not disclose anything about the requirement of foaming and good foam retention at the time of foaming on the hair, and a solution to that requirement.

In a hair dye of a foam type that is applied to hair, a surfactant is generally used as a foaming agent. In particular, anionic surfactants are known to have high foaming power and good foaming. Therefore, it is preferable to use at least an anionic surfactant as a foaming agent in a hair dye that does not use a former container or the like. Furthermore, in order to improve foam retention, it is preferable to use an amphoteric surfactant in combination.
Further, when the hair dye is sufficiently foamed, the contact area of the liquid portion of the foam with respect to the hair becomes insufficient, so that the hair coloring power becomes insufficient. More specifically, the hair dyeing is insufficient, and the hair is not dyed in a bright color due to insufficient bleaching power on the hair, resulting in low brightness after dyeing.

Next, in the multi-component hair dye applied to the hair in the form of foam, the viscosity in the foamed state or the defoamed state after that is lower than the viscous liquid mixture of each agent, and it becomes easy to flow. . Therefore, it is necessary to prevent the hair dye from dripping from the hair during the hair dyeing process after foaming.

In recent years, a so-called “2WAY type” has been proposed regarding hair dyes that are foamy and applied to hair. This type of hair dye can be a first hair dyeing method in which a viscous liquid mixture of each agent is applied to the hair and then foamed on the hair to perform a hair dyeing process. Similarly to the agent, a second hair dyeing method is also possible in which hair treatment is carried out as it is without foaming after application to the hair.
Here, in the case of a hair dye that is a viscous hair dye that is directly applied to the hair and does not lather, the viscosity of the drug affects the spread of the hair. In general, the lower the viscosity, the better the spread, but there is concern over dripping when applied to the hair. Furthermore, there is a concern that the hair dye may sag after application to the hair from the standpoint that if the viscosity of the drug at rest is low, it will flow easily. Therefore, it is necessary to prevent the hair dye from dripping from the hair during application and during the subsequent hair dyeing treatment.

Therefore, the 2WAY type hair dye must satisfy the following requirements (1a) to (1c) when used in the first hair dyeing method, and the second hair dyeing method described above. When used in the above, it is necessary to satisfy the following requirements (2a) to (2c).
(First hair dyeing method)
(1a) Good foaming and foam retention (1b) Sufficient dyeing and lightness of hair (1c) Prevention of dripping of hair dye during hair dyeing after foaming (second hair dyeing method)
(2a) Good spread to hair (2b) Sufficient dyeing and lightness of hair (2c) Prevention of dripping of hair dye during application and subsequent hair dyeing treatment

Therefore, the present invention provides a hair dye that uses a viscous liquid mixture of each of the hair dyes in the 2WAY type, and ensures foaming and foam retention when foamed on the hair, and spread to the hair. Good things are the first purpose. Next, a second object is to ensure sufficient dyeing and lightness of the hair by the hair dye. Furthermore, a third object is to prevent the hair dye from dripping during application and during the hair dyeing process.

(First invention)
A first invention for achieving the above object is a multi-component hair dye comprising a first agent containing an alkaline agent and a second agent containing an oxidizing agent,
The following (A) component and (B) component are contained in the viscous mixture of each agent of the hair dye, and the mass ratio of the content of the (B) component to the content of the (A) component (B) / ( A hair dye in which A) is in the range of 0.2 to 3.
Component (A): An ionic surfactant containing at least one component (A1) that is at least one anionic surfactant and component (A2) that is at least one amphoteric surfactant.
Component (B): One or more oily components containing at least a higher alcohol and having a total content in the range of 1 to 10% by mass.

(Second invention)
In the second invention for achieving the above object, the hair dye according to the first invention is used for the hair dyeing treatment of one or both of the following (1) and (2).
(1) After the viscous liquid mixture is applied to the hair, the hair is foamed on the hair to perform a hair dyeing treatment.
(2) After applying the viscous liquid mixture to the hair, the hair is processed without foaming on the hair.

In the above second invention, “used for both hair dyeing treatments (1) and (2)” means that the hair dyeing methods (1) and (2) for each specific part of the hair in the same hair dyeing treatment. Say to use the process properly. For example, the root part of hair and the hairline part suitable for hair dyeing treatment with a viscous liquid hair dye are subjected to the hair dyeing process of (2), and the other part of the whole hair ( The hair dyeing process of 1) can be performed. This also applies to the sixth invention described later.

(Third invention)
In the third invention for achieving the above object, the total content of the component (A) in the viscous liquid mixture of the hair dye according to the first invention or the second invention is in the range of 1 to 12% by mass. .

(Fourth invention)
In the fourth invention for achieving the above object, the component (A2) of the hair dye according to any one of the first to third inventions is a betaine-type amphoteric surfactant.

(Fifth invention)
In the fifth invention for achieving the above object, the (A1) component of the hair dye according to any one of the first to fourth inventions is a sulfate ester type anionic surfactant.

(Sixth invention)
A sixth invention for achieving the above object is a hair dyeing method using a hair dye,
A hair coloring method in which one or both of the following (3) and (4) is performed using the hair dye described in any one of the first to fifth inventions.
(3) After the viscous liquid mixture is applied to the hair, the hair is foamed on the hair to perform a hair dyeing treatment.
(4) After applying the viscous liquid mixture to the hair, the hair is treated without foaming on the hair.

When the hair dye of the first invention is used, when applying the viscous liquid mixture of each agent to the hair, and then lathering to the hair, (1a) good foaming and foaming, (1b) hair with the hair dye Sufficient dyeing and lightness can be secured, and (1c) it is possible to prevent dripping of the hair dye during the hair dyeing process after foaming. In addition, when the hair-dyeing treatment is applied to the hair after applying the viscous mixture of each agent to the hair, (2a) the hair spreads well, and (2b) the hair dyeing agent ensures sufficient dyeing and lightness. Furthermore, (2c) it is possible to prevent the hair dye from dripping down during application and during the subsequent hair dyeing treatment.
The effect of (2c) also means that the hair dye can be prevented from dripping at the time of application (before foaming) in the method of foaming hair on the hair.
From the above points, the first to third objects of the present invention described above can be achieved by using the hair dye of the first invention.

The reason why the above effects can be obtained is that the hair dye of the first invention contains an anionic surfactant as the component (A1) and an amphoteric surfactant as the component (A2) as the component (A). It is in the point. Component (A1) has high foaming power and good foaming. Further, the combined use of component (A2) improves foam retention. Due to the interaction between the component (A1) and the component (A2), both good foaming and good foam retention are achieved.

Next, when the foaming of the hair dye is good, the contact area of the liquid portion of the foam with respect to the hair is usually insufficient, and the hair dyeing power is insufficient. As a result, the dyeing of the hair is worsened, and the hair is not dyed in a light shade and the lightness is insufficient. However, the hair dye of 1st invention contains (B) component which is an oil-based component. The component (B) compensates for the shortage of the above-mentioned hair dyeing power by improving the affinity of the hair dye with respect to the hair. Therefore, even if the hair dye is well foamed, sufficient hair dyeing power can be secured, the hair is dyed well, and the lightness after dyeing is also good. However, when the content of the component (B) in the viscous liquid mixture of each agent of the hair dye is less than 1% by mass, the effect of ensuring the hair dyeing power and lightness cannot be substantially ensured. On the other hand, when the content of the component (B) exceeds 10% by mass, the ionic surfactant as the component (A) is taken in by the excess component (B) and defoamed, so that the hair dye is good. Foaming and foam retention are impeded.
Next, if the mass ratio (B) / (A) of the content of the component (B) to the content of the component (A) in the viscous mixture of the hair dye is inappropriate, the above effect cannot be obtained. However, in the first invention, since the mass ratio (B) / (A) is within an appropriate range of 0.2 to 3, the effect of the first invention is ensured. When the mass ratio (B) / (A) is less than 0.2, the blending effect of the component (B) cannot be substantially obtained due to the relative shortage of the component (B). When the mass ratio (B) / (A) exceeds 3, the foaming and foam retention of the hair dye become insufficient due to the relative excess of the component (B).

Furthermore, higher oil is blended as the oil component (B). Higher alcohol, as an oily component, exhibits an effect of ensuring hair dyeing power and brightness in a hair dye having good foaming, and at the same time imparts an appropriate viscosity to the 2WAY type hair dye. Therefore, dripping of the hair dye is prevented when the viscous liquid mixture of each agent of the hair dye is applied to the hair. Furthermore, in the first hair dyeing method in which the hair is processed by foaming on the hair after that, the hair dye is prevented from dripping during the hair processing after the foaming, and the hair is not foamed on the hair. Even in the second hair dyeing method in which the hair dyeing treatment is performed, dripping of the hair dye during the hair dyeing treatment after application to the hair is prevented.

From the above points, as specified in the second invention, the hair dye of the present invention has a suitable use as a 2WAY type hair dye.

According to the third invention, since the total content of the component (A) in the viscous mixture of the hair dye is in the range of 1 to 12% by mass, the effect of the first invention is particularly remarkable. . When the total content of the component (A) in the viscous liquid mixture is less than 1% by mass, it is difficult to obtain the good foaming and foam retention when the hair dye is foamed on the hair. When the total content exceeds 12% by mass, the hair dye is sufficiently foamed, and the contact area of the liquid part of the foam with respect to the hair is insufficient, so that it is difficult to ensure sufficient dyeing and lightness of the hair.

According to the fourth invention, since the amphoteric surfactant as the component (A2) is a betaine-type amphoteric surfactant, the hair dye composition is compared with the case where an amphoteric surfactant other than the betaine-type surfactant is blended. The foam retention during foaming is particularly good.

According to the fifth invention, since the anionic surfactant as the component (A1) is a sulfate ester type anionic surfactant, it is compared with the case where an anionic surfactant other than the sulfate ester type is added. Thus, the foaming of the hair dye is particularly good.

The hair dye of the present invention can be suitably used as a 2WAY type hair dye as defined in the sixth invention.

Next, modes for carrying out the present invention will be described including the best mode.
