Description

Hair dye composition {HAIR DYE COMPOSITION}

The present invention relates to a hair dye composition. More specifically, it contains an oxidizing dye and a specific acidic direct dye, at least one antioxidant selected from L-ascorbic acid, L-cysteine and salts thereof, and an oxidizing agent to brighten hair and maintain color It relates to a hair dye composition having good and excellent day-to-day stability.

Conventionally, as a hair dye, an oxidized hair dye using an oxidizing dye is known, and a two-agent type consisting of a first agent containing an oxidizing dye or an alkali agent and a second agent containing an oxidizing agent such as hydrogen peroxide is widely used.

In such a two-agent oxidation hair dye, the oxidation dye penetrates into the hair and oxidatively polymerizes to dye the hair. At the same time as hair dyeing, since the alkali agent contained in the first agent decomposes and decolorizes melanin in the hair by oxygen generated by decomposing the oxidizing agent contained in the second agent, it is possible to increase the brightness of the hair. For this reason, oxidation hair dyes have a high hair dyeing effect, good color retention, and bright colors, but have a problem in that it is difficult to express vivid color tones.

On the other hand, acidic hair dyes using acidic direct dyes are also popular. For example, Patent Document 1 reports a hair dye containing a dyeing aid such as an acidic direct dye and an aromatic alcohol, and an oxidizing agent, and adjusting the pH of the mixture at the time of hair dyeing to 7.5 to 11.

Further, in Patent Document 2, two types of solutions, a first liquid containing an acid direct dye, an alkali and a polymeric thickener, and a second liquid containing hydrogen peroxide, having a pH of 4 or less, are mixed, and the pH is 9.0 or more, and specific There has been reported a hair bleaching and dyeing method in which a composition having a viscosity is applied to the hair.

Although these hair dyes can express bright and vivid color tones, the hair dyeing effect and color retention are insufficient.

In addition, Patent Document 3 reports a hair dye composition containing a specific amount of an oxidizing dye intermediate, an acidic direct dye, and an oxidizing agent. In this composition, although it is possible to express a vivid color tone while brightening the hair, there is a problem in that the acidic direct dye is decomposed by the antioxidant formulated to prevent oxidative polymerization of the oxidizing dye, and the shelf life stability is not excellent.
