Description

  The present invention relates to an oxidative hair dye composition.

  In general, the oxidative hair dye is generally of a two-part formula comprising a first agent containing an alkaline agent and a second agent containing hydrogen peroxide. This two-part oxidative hair dye generates oxygen by mixing the first agent and the second agent at the time of use, and oxidatively decomposes melanin pigment in the hair with this oxygen, and also converts the oxidative dye into the hair. To oxidatively polymerize and dye hair. In addition to the action of hydrogen peroxide, the alkaline agent in the first agent has an effect of improving the hair dyeing effect by swelling the cuticle on the hair surface and penetrating the dye into the hair. For this reason, compared with a temporary hair dye, an acid hair dye, etc., it is possible to dye in a lighter color tone than the original hair, and there is an advantage that the hair dyeing effect is continuous.

  However, since the oxidative hair dye needs to be mixed with the first agent and the second agent at the time of use and the oxidative polymerization reaction of the dye is performed on the hair, the hair is uniform according to the mixed state of the two agents. There is a problem that it is hard to be dyed. In addition, since an alkaline agent is used, the keratin protein on the hair surface is decomposed to damage the hair, and the hair after dyeing has a problem that it is inferior in fingering and gloss.

  In order to solve such a problem, a hair dye containing a dimethyldiallylammonium chloride / acrylic acid copolymer and a protein hydrolyzate (see Patent Document 1), 2- (β-hydroxyethyl) -p-phenylene Oxidative hair dyes containing diamine and two or more specific protein hydrolysates (see Patent Document 2), hair dyes containing marine collagen hydrolyzate and silicone derivatives (see Patent Document 3), etc. Proposed.

  However, these hair dyes are intended to impart luster and fingering properties to the hair using a protein hydrolyzate, and the imparted effects are not yet satisfactory.
