  In an oxidative hair dye comprising an agent I containing an oxidative dye and an agent II containing an oxidizer, a cream type is generally known as the agent I and a liquid type is generally known as the agent II.

  The creamy agent I contains an oil component, and thereby imparts various effects [hair texture / feel / lightness, adhesiveness (how to ride on hair, etc.)]. Therefore, when the amount of oil is increased, these effects can be further improved and imparted more sufficiently and at a high level.

  On the other hand, increasing the amount of oil in the creamy agent I increases the viscosity, and as a result, the viscosity at the time of mixing with the agent II may increase. Therefore, it takes time for uniform mixing operation and treatment (hair dyeing treatment) of these two agents, careful combing is required and hair is damaged, the hair dye does not easily penetrate into the hair, and the dyeing power is reduced, or so-called There was a problem that pinpoint treatment was difficult.

  By the way, in Patent Document 1 (Claim 3), it is proposed to use particulate oil in order to solve these problems without suppressing the amount of oil.
