Description

  The present invention relates to a two-component hair cosmetic that can be easily applied without unevenness on the hair by discharging a mixture of a two-component hair bleaching agent or a two-component hair dye in the form of foam.

  Conventionally, liquid or cream-like hair cosmetics such as hair bleaching agents and hair dyes have been widely used, but it is difficult to apply them uniformly to hair. In particular, skills such as blocking and a matching mirror are required to apply the root portion and the back of the hair inside the hair, and a lot of time is required.

  On the other hand, it has been proposed to simplify the hair dyeing operation by discharging the agent in the form of foam. For example, a two-component hair dye is simultaneously discharged in a foam form from a discharge container of a type in which two aerosol cans are connected (see Patent Document 1), and a one-component hair bleaching agent is used as a former such as a pump former. There is a non-aerosol type that is filled in a container and discharged in the form of foam (see Patent Document 2).

JP-A-10-287534 JP-A-9-227347

  However, those using a discharge container of a type in which two aerosol cans are connected cause the first agent and the second agent to be discharged from independent aerosol cans. May occur.

  On the other hand, the one-type hair bleaching agent filled in the former container is applied to the hair without activating the hydrogen peroxide, and the effect obtained by one treatment is scarce and the bleaching is performed with sufficient brightness. In order to do this, it is necessary to leave it for a long time after applying the agent (for example, applying it in the morning and washing it away at night), and it is necessary to repeat several treatments.

  On the other hand, the present invention prevents uneven bleaching or uneven dyeing by discharging a two-component hair decoloring agent or two-component hair dye from the former container in the form of foam, and has sufficient decoloring power or hair coloring power. It aims to be able to obtain.

  In order to achieve the above object, the present invention provides a former for discharging a first agent containing an alkali agent, a second agent containing hydrogen peroxide, and a mixture of the first agent and the second agent in the form of foam.

  According to this two-component hair cosmetic, a two-component hair bleaching agent or a mixture of two-component hair dyes is discharged in the form of foam and can be applied to the hair easily and without unevenness. The foam of the two-part hair bleaching agent or the two-part hair dye discharged from this two-part hair cosmetic has a foam quality that is easy to adjust to the hair, causing irritation to the scalp and scattering of the agent. And has sufficient decoloring power or dyeing power. Therefore, the hair cosmetic composition of the present invention can achieve a uniform decolorization finish or hair dye finish with little unevenness.

  Moreover, the liquid mixture discharged in the form of foam by gas-liquid mixing using the former container easily reaches the base of the hair, but there is no accumulation of liquid and the like, and it spreads to the whole hair moderately thinly. Therefore, the root portion does not become extremely bright like conventional liquids or creams, and decoloring unevenness or dyeing unevenness due to uneven adhesion of the mixed liquid does not occur. Therefore, by applying the liquid mixture discharged in the foam according to the present invention to the hair near the newly formed part such as the dividing line and the face line, the color difference between the newly formed part and the already dyed part is eliminated, and a natural finish is achieved. Obtainable. Moreover, since a liquid mixture can be apply | coated to hair moderately thinly, the damage to hair is reduced.

Squeeze foamer bottle (manufactured by Daiwa Steel Co., Ltd., volume 150 mL, mesh roughness (mesh) is 200 mesh per mixing chamber (200 mesh per 1 inch (25.4 mm)), tip 255 mesh) From the time when the remaining amount is 80 g, 20 g of foam is discharged into a 1000 mL measuring cylinder, and the volume of the foam is measured 1 minute after the first discharge. The gas-liquid mixing ratio (mL / g) is obtained by dividing the volume (mL) of the discharged foam by the weight of 20 g.

  In addition, it is preferable to adjust the viscosity of the mixed solution to the above range because squeeze is easily performed when bubbles are discharged by a squeeze foamer or the like. In order to adjust the viscosity of the mixed solution of the first agent and the second agent within the above range, a water-soluble solvent such as ethanol is added, or the surfactant, polyols, and higher alcohol content What is necessary is just to adjust a kind suitably.

It is preferable.

  As the product form of the two-component hair cosmetic composition of the present invention comprising the first agent, the second agent and the former container, the first agent or the second agent is filled in a container separate from the former container, and both are used at the time of use. The agent may be transferred to the former container and mixed, but one agent is filled into the former container, the other agent is filled into a separate container, and the other agent is transferred into the former container at the time of use. You may make it enter. In this case, the second agent is preferably placed in a gas-permeable container in order to prevent the pressure in the container from increasing due to oxygen generated by the decomposition of hydrogen peroxide, while the first agent is In order to prevent oxidation of the oxidation dye and volatilization of ammonia, it is necessary to use a container that does not easily transmit oxygen. Therefore, it is preferable to fill the second agent with a former container made of an oxygen-permeable material (for example, polyethylene).

  In addition, as a method of using the two-component hair cosmetic of the present invention, the first agent and the second agent are mixed in a former container, and the foamy agent discharged from the container is directly applied to the hair.
