Description

  The present invention relates to an aerosol type hair dyeing product or a hair bleaching cosmetic product.

  Conventionally, a double-structured container (hereinafter referred to as “separate filling / same pressure discharge”) having a mechanism in which the first agent and the second agent of hair cosmetics are separately filled and simultaneously discharged by the same pressure discharge system. Called "molded double-structured containers"). For example, Patent Document 1 and Patent Document 2 disclose a double-structured container having such a mechanism basically as a double-structured container of this separate filling / same pressure discharge type.

  Due to the mechanism of these separate filling / same pressure discharge type dual structure containers, the outer container filled with the propellant needs to be robustly constructed. For the bag-shaped body filled with the first agent and the second agent, It is necessary to use a material that is relatively flexible and easily deformed by pressurization so that the content can be reliably discharged by the pressure of the propellant for pressurization.

  Therefore, the impact resistance strength is often different between the outer container and the bag-like body. Therefore, when the double structure container receives a large impact, for example, when the double structure container is removed from the hand and collided with a hard floor surface during use, the first agent and the second agent are added. There is a possibility that the filled bag-like body, the connection portion between the opening of the bag-like body and the discharge path of the lid, etc. are damaged, and the liquid leaks out. In oxidative hair dyes and hair bleaching agents, when the first agent blended with the alkali agent and the second agent blended with hydrogen peroxide are mixed, oxygen gas, carbon dioxide gas, ammonia are reacted by the reaction between the components in each agent. Gas such as gas is generated. Even when the first agent and the second agent leak out of the inner container due to breakage of the bag-like body or the like, both may contact and mix to generate reaction gas inside the outer container. . Therefore, Patent Document 3 proposes that the mixing of the respective agents is suppressed and the generation of the reaction gas is suppressed by setting both the first agent and the second agent to have a specific viscosity or more.

  Here, in order to achieve high decolorization, the present inventors highly blended the alkaline agent of the first agent and increased the hydrogen peroxide concentration of the second agent, so that the opening of the bag-like body and the discharge path of the lid It is difficult to maintain the liquid-tightness (seal) of the connecting part with the liquid, and each agent is mixed when the first agent and the second agent leak out of the inner container due to breakage of the bag-like body or the like It was found that the generation of reactive gas during the process could not be suppressed. The capacity of the outer container in the double container of separate filling and same pressure discharge type is usually only about 40 to 150 mL when the volume of the first and second agents filled in the bag-like body is subtracted, Even if the amount of reaction gas generated is small, the gas pressure inside the outer container may rise to a level that cannot be ignored. An excessive rise in the gas internal pressure of a robust and airtight container leads to the risk of rupture, so countermeasures are desired.
