Description

  The present invention relates to an oxidative hair dye or a decoloring composition.

  For hair decolorization and dyeing, an oxidative hair dye or a decolorant composition that decolorizes or dyes hair by an oxidation reaction in the presence of an alkaline agent contained in the first agent and an oxidizing agent contained in the second agent. Is widely used.

  However, such an oxidative hair dye or depigmenting composition is liable to cause hair damage, causing tangling of hair, hardness, wrinkle, etc., hair color and gloss when washed with water, shampoo or dry. It has the problem that it disappears or the unity becomes worse. 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, etc., but these additions are carried out by washing and rinsing after treatment. Since most of the agent was washed away and the residual amount on the hair was reduced, these effects were not fully satisfactory.

  Therefore, it has been proposed to use a highly polymerized silicone and a cationic polymer in combination in order to further improve the good feel after finishing and its sustainability. For example, a decoloring or dyeing composition using an amino-modified silicone, a highly polymerized silicone, and a cationic polymer has been proposed (Patent Document 1). However, this decoloring or dyeing composition has a good feel when the agent is washed away from the treated hair with running water, but is inferior to the feel when washing with a shampoo and when rinsing, and after drying. The color persistence was not enough. In addition, a hair dye composition using an aqueous emulsion of a high molecular silicone having a specific particle size and a dimethyldiallylammonium chloride / acrylic acid copolymer has been proposed (Patent Document 2). However, this hair dye composition has a problem that it causes a squeaky or stiff feeling when the agent is washed from running hair with running water.
