Description

  The present invention can uniformly dye or decolorize from the root to the tip of the hair without damaging the hair, has good hair color and gloss, good cohesiveness and moisture retention after drying, and their durability. It is related with the 1st agent composition for emulsification type oxidative hair dyeing or decoloring which is favorable and has good emulsification stability.

  For dyeing and decoloring hair, an oxidative hair dye or decoloring agent that dyes or decolors hair by an oxidation reaction in the presence of an alkali agent, an oxidizing agent, or the like is widely used.

  However, oxidative hair dyes or depigmenting agents are liable to cause damage to the hair, causing entanglement, hardness, or stiffness of hair when washed with water, shampooing or drying, and causing hair color and gloss to be lost or clumping. It gets worse. Furthermore, such hair damage accumulates due to repeated decolorization or dyeing, and is particularly noticeable at the hair ends where the number of treatments increases. For this reason, since the degree of damage is different between the root portion and the hair tip portion, there is a problem that unevenness is likely to occur when the hair is dyed or decolored, and the color of the hair tip portion is likely to be removed by washing with shampoo.

  Therefore, in order to cope with these problems, an additive having a conditioning action is used. For example, by adding a silicone derivative such as amino-modified silicone oil, the hair is dyed in a deep color tone (see Patent Document 1), and by adding a polyorganosiloxane having an amino group, the hair is softly touched, It has been reported that hair setability is improved (see Patent Document 2), hair damage is prevented by adding highly polymerized silicone or a derivative thereof, and touch is improved (see Patent Documents 3 and 4). ing.

  However, in the dyeing or decoloring treatment, since the treatment agent is rinsed off with water and shampoo after the treatment, most of the additives having a conditioning action are washed away, resulting in a small residual amount on the hair. The effect of was not fully satisfactory.
