Description

The present invention relates to an aerosol-type hair dye or decolorizing agent composition.

In a general creamy hair dye, the first agent contains an alkaline agent or a dye, and the second agent contains an oxidizing agent. In this creamy hair dye, the first agent and the second agent are transferred to a tray container before hair dyeing, mixed at the time of use, and then the hair is dyed using a brush. Therefore, the mixed solution of the first agent and the second agent prepared before hair dyeing may be insufficient or too much. If it is insufficient, the first agent and the second agent are mixed again before use, and then the hair is dyed with a brush. On the other hand, if the amount is too large, it cannot be set aside and will be discarded, resulting in wasteful work and cost. Further, in recent years, there has been a demand for gray hair dyeing called "early dyeing type" that dyes gray hair in a short time, and in order to realize "early dyeing", the first agent contains a high concentration of alkaline agent or dye. In many cases.

On the other hand, in the creamy two-agent aerosol type hair dye or decolorizing agent composition, the first agent and the second agent are directly discharged to the brush, respectively, and the first agent and the second agent are fixed on the brush. Apply directly to hair to dye or bleach. Therefore, the hair can be dyed or decolorized without getting the hands dirty, and the first and second agents can be discharged from the aerosol container as much as desired, so that it is "insufficient" or "too much". ] And other problems are unlikely to occur. Also, by using a brush, the first and second agents cannot be touched, so when you pick up the aerosol container or press the button on the aerosol container to discharge the first and second agents. At that time, there is no need to worry about the aerosol container slipping off the hand.

As such a two-agent aerosol type hair dye or decolorizing agent composition, the first interior pouch filled with the first agent and the second interior pouch filled with the second agent are housed in one pressure-resistant container for interior decoration. A creamy two-agent aerosol-type hair dye or decolorizing agent composition is disclosed in which a compressed gas is filled between a pouch and a pressure-resistant container, and the same pressure is applied to simultaneously discharge the first agent and the second agent. (Patent Document 1).

Japanese Unexamined Patent Publication No. 2014-237621

However, in Patent Document 1, although consideration is given to the balance between the discharge amounts of the first agent and the second agent discharged from the aerosol container and the suppression of dripping, the first agent and the first agent discharged to the brush are considered. No consideration is given to the extensibility of each of the first agent and the second agent when the two agents are applied to the hair. If the extensibility of either the first agent or the second agent is deteriorated, the first agent and the second agent may not be uniformly applied on the hair surface. Therefore, the first agent and the second agent cannot be mixed on the surface of the hair in a predetermined ratio, and as a result, unevenness may occur.

Further, in the case of a hair dye, a high concentration alkaline agent or dye is often blended in the first agent. Therefore, the stability of the first agent is lowered, and it tends to be difficult to sufficiently secure the stability especially under high temperature conditions. For example, when a product is transported by land, the temperature inside the vehicle rises to about 60 ° C. in summer, and the product is stored in a high temperature state for a long period of time. If this state continues for a long time, if the product is an emulsion, the emulsified structure may be destroyed and separation or the like may occur. Therefore, a technique for improving stability under high temperature conditions is also desired.

Therefore, according to the present invention, in the aerosol-type hair dye or decolorizing agent composition, both the first agent and the second agent have good extensibility when applied to the hair, and the first agent and the second agent under high temperature conditions. It is an object of the present invention to provide an aerosol-type hair dye or decolorizing agent composition which is stable and has good hair dyeing property.

The hair dyeing property in the present invention means dyeing property, bleaching property, or both.

As a result of diligent studies to solve the above problems, the present inventor is an aerosol-type hair dye or decolorizing agent composition, and both the first agent and the second agent are (A) glycerin, polyethylene glycol, and dipropylene glycol. , At least one selected from diglycerin and 1,3-butylene glycol, (B) polyoxyethylene alkyl ether, (C) higher alcohol having 16 to 22 carbon atoms, (D) oily component ((C).
