Description

  The present invention relates to a hair bleaching or dyeing composition used by mixing a first agent containing a volatile alkaline agent and a second agent containing an oxidizing agent.

  For dyeing and decoloring hair, two-component permanent hair dyes and bleaching agents comprising a first agent containing an alkaline agent and a second agent containing an oxidizing agent are widely used. However, conventional two-component permanent hair dyes or depigmenting agents generally use ammonia as an alkaline agent, and when the first agent and the second agent are mixed or applied to the hair, stimulation of ammonia. Odor is generated. Furthermore, when the ammonia content is increased for the purpose of improving dyeability or decolorization, ammonia-stimulated odor and eye irritation are further increased.

  As a means to alleviate these, there is a method in which a part of ammonia is replaced with alkanolamine such as monoethanolamine. However, if the dyeing property or decoloring property is inferior, or if alkanolamine is contained in a large amount, There was a problem that stimulation increased.

  On the other hand, if a component having a cationic functional group used for the purpose of improving the feel of hair (eg, cationic surfactant, cationic polymer, etc.) is contained, the structure of the composition becomes unstable, resulting in an ammonia-stimulating odor. There was also a problem that it was likely to occur.

  Therefore, in order to deal with these problems, a composition containing two kinds of nonionic surfactants having different alkali agents, higher alcohols, and HLBs (see Patent Document 1), alkali agents, and surfactants. And a composition containing two types of higher alcohols having different carbon numbers in a specific ratio (see Patent Document 2), two types of nonionic surfactants having different HLB, cationic surfactants, higher alcohols and volatilization A composition containing a basic alkali in a specific ratio (see Patent Document 3), a composition containing isoparaffin and a polymer compound (see Patent Document 4), and the like have been proposed.

  However, none of these was sufficiently satisfactory in the mixing properties of the first agent and the second agent, the difficulty of dripping, dyeing properties, decoloring properties and hair feel.
