Description

  The present invention relates to a decolorizing or hair dye composition.

  For the decolorization or dyeing treatment of hair, a two-component decoloration or hair coloring in which a first agent containing an alkali agent and the like and a second agent containing an oxidant are mixed and the hair is decolored or dyed by an oxidation reaction. Agent compositions and one-component acidic hair dye compositions using acidic dyes are widely used.

  Among these, the above-mentioned two-component decoloring or hair dye composition causes hair damage, and causes entanglement of hair and deterioration of touch during washing with water and shampooing. Furthermore, the entanglement of the hair causes the loss of gloss and the poorness of the hair after finishing. In addition, the hair after dyeing is further damaged by physical stimulation by daily hair care behavior such as heat or brushing by a dryer or a hair iron. For this reason, there is a problem that the touch due to the tangling of the hair is further deteriorated at the time of washing with water and shampoo, and the gloss and unity of the finished hair is further reduced. Therefore, in order to deal with these problems, it has been carried out to add ingredients having conditioning action such as amino-modified silicone, highly polymerized silicone, cationic polymer to the two-component decoloring or hair dye composition, Since most of these additives are washed away by rinsing and rinsing after the treatment, and the residual amount on the hair is reduced, their effects are not fully satisfactory.

  Therefore, in order to improve the effects such as the feeling when wet and after drying, its durability, and color retention, together with amino-modified silicone and highly polymerized silicone, a specific cationic polymer is allowed to coexist to improve the amount of adsorption of silicones. Technology has been proposed (Patent Document 1). However, the sustainability of the effect was limited and not fully satisfactory.

  On the other hand, by using amphoteric or cationic polymers in combination with anionic polymers, there has been proposed a decoloring or hair dye composition that improves the gloss and flexibility of the hair, and that provides a natural dyeing and sufficient fastness. (Patent Document 2). However, this document does not describe at all the sustainability of effects such as good feeling during washing and shampooing, good hair gloss after finishing, and unity.
