Description

  The present invention relates to a hair dye composition and a decoloring composition in which part or all of the oil component is encapsulated in a capsule in the hair dye composition and the decoloring composition.

In general, a hair dye composed of an oxidation dye and a first dyeing agent containing an alkaline agent for improving the permeability of the oxidation dye and a second dyeing agent containing an oxidizing agent for coloring the oxidation dye. Agent compositions are known. Moreover, the decoloring agent composition comprised from the decoloring 2nd agent which mix | blends the oxidizing agent for decolorizing the melanin contained in hair, and the decoloring 1st agent which mix | blends the alkaline agent for improving the permeability of this oxidizing agent It has been known. In such a hair dye composition, the hair dye first agent and the hair dye second agent are mixed immediately before use, and the mixture is applied to dye the hair. Similarly, in the bleaching composition, the bleaching first agent and the bleaching second agent are mixed immediately before use, and the mixture is applied to decolorize the hair. Conventionally, for example, as disclosed in Patent Document 1, at least one of the first hair dyeing agent and the second hair dyeing agent is blended with oily components such as fats and oils for the purpose of improving the feel and brightness of the hair. Agent compositions are known. Increasing the blending amount of such oily components leads to improvements in feel, brightness, etc., while the viscosity of the drug also increases. Accordingly, when a large amount of oily component is contained, the property of the hair dye changes from liquid to cream (gel). When mixing the first dyeing agent and the second dyeing agent using the brush and tray used in partial dyeing etc., even if both the first dyeing agent and the second dyeing agent are creamy, Mixing and stirring were possible.

  The content of the (A) oxidation dye in the hair dye mixture is preferably 0.02 to 30% by mass, more preferably 0.2 to 20% by mass. If the content is less than 0.02% by mass, sufficient dyeability may not be obtained. On the other hand, even if it exceeds 30 mass%, the dyeability is not improved and it is not economical.

If the content is less than 0.01% by mass, sufficient dyeability may not be obtained. On the other hand, even if it exceeds 15 mass%, the dyeability is not improved and it is not economical.

  The content of the coupler in the hair dye mixture is preferably 0.01 to 15% by mass, more preferably 0.1 to 10% by mass.

Among these (B) alkali agents, since it is easy to improve the permeability of the (A) oxidative dye to hair, it is preferably at least one selected from ammonia and alkanolamines.

  The blending amount of this (B) alkaline agent is preferably set to an amount such that the pH of the first dyeing agent is in the range of 8-12. If the pH of the first hair dye agent is less than 8, the action of hydrogen peroxide (oxidant) may not be sufficiently promoted when the first hair dye agent is mixed with the second hair dye agent. On the other hand, when pH exceeds 12, when hair dye composition is applied to hair, troubles, such as damage, are easy to occur to hair. In the case of preparing particles by coating (D) the oil component with a calcium alginate coating in the hair dyeing second agent, since the calcium alginate dissolves in alkali, (B) the alkali agent is combined with the hair dyeing first agent and the hair dyeing.

The dosage form of this hair dye mixture is not particularly limited, such as liquid, cream, gel, and foam. (D) From the viewpoint of dispersing and mixing particles containing an oil component in the hair dye mixture, a liquid having a low viscosity is preferred.

  The preservation | save form and mixing method of the hair dye 1st agent and hair dye 2nd agent which were mentioned above are not specifically limited. For example, the hair dye first agent and the hair dye second agent are filled separately in the container, and filled into an aerosol container having a simultaneous discharge mechanism that can be mixed and discharged from one discharge port when discharged from the container. May be. Alternatively, a dedicated tray may be used, and the first dyeing agent and the second dyeing agent may be mixed and stirred on the tray using a brush. Moreover, you may mix by filling the hair dye 1st agent and the hair dye 2nd agent in one storage container, and shaking a storage container up and down. Thereby, (D) the particle | grains containing an oil-based component disperse | distribute and disintegrate in a hair dye mixture by mixing and stirring processing. Moreover, when particles are produced with a calcium alginate coating, the calcium alginate film dissolves and disintegrates due to the hair dye mixture showing alkalinity by the action of (B) an alkali agent. Then, at the same time as the particles are dispersed in the hair dye mixture, (D) the oily component in the particles diffuses.

The effects exhibited by the first embodiment will be described below.
(1) In the first embodiment, in the hair dye composition comprising the first hair dye agent and the second hair dye agent, (D) a part or all of the oil component is blended as particles. Therefore, the viscosity of the liquid agent can be kept low as compared with the case where (D) the oil component is not blended as particles. That is, the mixing property of the hair dye can be enhanced in the hair dye composition containing the oil component. For example, an aerosol container or the like having a simultaneous discharge mechanism in which the hair coloring first agent and the hair coloring second agent are separately filled in the container and can be mixed and discharged from one discharge port when discharged from the container. Even in such a case, since the viscosity of the liquid agent can be suppressed, the mixing property can be improved. By improving the mixability of the hair dye composition, the effects of brightness, touch, and the like caused by the improvement of the dyeability and the addition of an active ingredient such as an oil component can be sufficiently exhibited.

  (2) Moreover, (D) The addition amount of an oil-based component as particle | grains can increase the compounding quantity of (D) oil-based component, suppressing the viscosity raise of a liquid agent. Therefore, the feel and brightness of the hair can be improved.

  (3) Moreover, even when using a brush and a tray for applying the hair dye mixture to the hair, the viscosity of the liquid agent can be kept low during mixing, so that the mixing process on the tray can be easily performed. it can.

  (4) In addition, since part or all of the oil component that is blended as a capsule during storage does not directly react with other blend components, (D) the oil component is blended stably into the second hair dyeing agent for a long period of time. can do.

(5) In 1st Embodiment, the particle size of particle | grains was 0.1-10 mm. Therefore, since the particles are efficiently suspended and dispersed in the liquid agent, the mixing property of the hair dye can be further improved.
In addition, since the particles having such a size can be visually confirmed, the container for filling the hair dye composition is made beautiful by making the container for the liquid agent in which the particles are blended transparent or translucent. Can be granted. In addition, when using alginate, agar, or gelatin as the particle forming material, the particles become transparent or translucent, so that by adding a coloring agent to the particles, the hair dye composition further imparts beauty. be able to.

  (6) In the first embodiment, a hair dye composition comprising (A) an oxidation dye and (B) a first hair dye containing an alkaline agent and (C) a second hair dye containing an oxidizing agent. At least one of (D) particles containing an oil component was blended. Therefore, the particles easily disintegrate in the mixing process of the normal first dyeing agent and the second dyeing agent.

  (7) In the first embodiment, a hair dye composition comprising (A) an oxidation dye and (B) a first hair dye containing an alkaline agent and (C) a second hair dye containing an oxidizing agent. In (1), for example, (D) an oil component was filled in a capsule having a calcium alginate coating and blended in the second hair dyeing agent. Thereby, when the hair dye 1st agent and the hair dye 2nd agent are mixed, when the hair dye mixture changes to alkaline, the calcium alginate coating dissolves and disintegrates in the hair dye mixture. Therefore, the capsule disintegration work in the hair dye mixture can be easily performed.

Hereinafter, a second embodiment that embodies the bleaching agent composition of the present invention will be described in detail.
The bleaching agent composition of the second embodiment is composed of (E) an alkali agent, (F) an oxidizing agent, and (G) an oil component, and at least a part of the (G) oil component is blended as particles. . For example, the decoloring agent composition of the second embodiment includes a decoloring agent first agent as a first agent (hereinafter referred to as a decoloring first agent) and a decoloring agent second agent as a second agent (hereinafter referred to as decoloring second). It is made up of two agents. In this case, the decolorization first agent contains (E) an alkali agent, and the decolorization second agent contains (F) an oxidizing agent and (G) an oily component blended as particles. The decolorization 1st agent and the decolorization 2nd agent are mixed at the time of use, and the decoloring mixture as a mixture can be obtained. By applying this decolorization mixture to the hair, the hair can be decolorized. First, the decolorizing second agent will be described.

<Decolorizing second agent>
This decoloring second agent contains (F) an oxidant and (G) an oil component blended as particles. In addition, the decolorizing second agent contains components usually used for the decoloring second agent as other components.

  (F) An oxidizing agent is mix | blended in order to decolorize the melanin contained in hair. (F) As the oxidizing agent, (C) the oxidizing agent blended in the hair dye composition described above can be applied. The content of (F) oxidizing agent in the decolorization mixture is preferably 0.1 to 10.0% by mass, more preferably 0.5 to 8.0% by mass, and most preferably 1.0 to 6.0% by mass. %. If the content is less than 0.1% by mass, melanin may not be sufficiently decolorized. On the other hand, if the amount exceeds 10.0% by mass, there is a possibility that defects such as damage occur in the hair.

  (G) The oil component is blended in order to improve the feel and lightness of the hair by facilitating the application of the decoloring agent composition to the hair and imparting softness and moisture to the hair. As the (G) oil component, the (D) oil component blended in the hair dye composition described above can be applied. (G) Content of an oil-based component becomes like this. Preferably it is 0.01-50.0 mass% in a decoloring 2nd agent, More preferably, it is 0.1-30.0 mass%. When the blending amount is less than 0.01% by mass, the effect of improving the touch such as softness and moisture to the hair cannot be sufficiently exhibited. On the other hand, if it exceeds 50.0% by mass, the effect is not further improved, and the touch is lowered.

(G) The particle | grain composition mix | blended with the hair dye composition mentioned above may be applied also to the property of the particle | grains mix | blended with an oil-based component.
The decolorizing second agent may contain the above-mentioned water, surfactant, polyhydric alcohol and the like as other components.

<Decolorization first agent>
The decolorization first agent in the second embodiment contains (E) an alkali agent. Moreover, this decoloring 1st agent contains the component normally used for the decoloring 1st agent as another component.

  (E) The alkaline agent is blended in order to improve the permeability of the (F) oxidizing agent to the hair and to improve the decolorization property by swelling the hair. (E) As an alkali agent, (B) an alkali agent blended in the hair dye composition described above may be applied. It is preferable to set the pH of the decolorizing first agent in an amount in the range of 8-12. If the pH of the decolorizing first agent is less than 8, the action of hydrogen peroxide (oxidizing agent) may not be sufficiently promoted when the decolorizing first agent is mixed with the decolorizing second agent. On the other hand, when the pH exceeds 12, defects such as damage are likely to occur in the hair when the depigmenting agent composition is applied to the hair. The decolorizing first agent may contain the above-described water, surfactant, polyhydric alcohol, and the like as other components.

<Decolorization mixture>
When using a decoloring agent composition, a decoloring mixture can be obtained by mixing and preparing the above decoloring first agent and decoloring second agent at a predetermined ratio. The dosage form of this decolorization mixture is not particularly limited, such as liquid, cream, gel, foam and the like. (G) From the viewpoint of dispersing and mixing the particles containing the oil component in the decolorized liquid mixture, a liquid having a low viscosity is preferred.

  The preservation | save form and mixing method of the decoloring 1st agent and the decoloring 2nd agent which were mentioned above are not specifically limited. For example, the first decolorizing agent and the second decolorizing agent are filled separately in the storage container, and can be filled into an aerosol container having a simultaneous discharge mechanism that can be mixed and discharged from one discharge port when discharged from the storage container. Good. Alternatively, a dedicated tray may be used, and the first and second decolorizing agents may be mixed and stirred on the tray using a brush. Moreover, you may mix by filling the decoloring 1st agent and the decoloring 2nd agent in one storage container, and shaking a storage container up and down. Thereby, the particle | grains containing (G) oil-based component disperse | distribute in a decoloring mixture by a mixing and stirring process, and disintegrate. In addition, when particles are formed with a calcium alginate coating, (E) the calcium alginate film dissolves and disintegrates due to the alkalinity of the decolorized mixture by the action of the alkali agent. Then, at the same time as the particles are dispersed in the decolorization mixture, the (G) oily component in the particles diffuses.

The effect exhibited by the above second embodiment will be described below.
(1) In the second embodiment, in the decolorizing agent composition comprising the decoloring first agent and the decoloring second agent, (G) part or all of the oil component is blended as particles. Therefore, compared with the case where (G) an oil component is not mix | blended as particle | grains, the viscosity of a liquid agent can be restrained low. That is, the mixing property of the decoloring agent can be enhanced in the decoloring agent composition containing the oil component. For example, when an aerosol container having a simultaneous discharge mechanism that can be mixed and discharged from one discharge port when the decolorization first agent and the decolorization second agent are separately filled in the storage container and discharged from the storage container is used Even so, since the viscosity of the liquid agent can be suppressed, the mixing property can be improved. By improving the mixing property of the decoloring agent composition, the effect of improving the decoloring property and the brightness, feel and the like caused by the addition of an active ingredient such as an oily component can be sufficiently exhibited.

  (2) Further, by adding the (G) oil component as particles, the amount of the (G) oil component can be increased while suppressing an increase in the viscosity of the liquid agent. Therefore, the feel and brightness of the hair can be improved.

  (3) Moreover, even when using a brush and a tray for applying the decolorization mixture to the hair, the viscosity of the liquid agent can be kept low during mixing, so that the mixing process on the tray can be easily performed. .

  (4) Also, since part or all of the (G) oil component that is blended as a capsule during storage does not react directly with other blend components, (G) the oil component is blended stably into the decolorizing second agent for a long period of time. be able to.

In addition, the said embodiment can also be changed and actualized as follows.
