JP7139267B2 - hair dye composition - Google Patents

Description

The present invention relates to hair dye compositions. More specifically, it contains an oxidation dye, a specific acid direct dye, L-ascorbic acid, L-cysteine and at least one antioxidant selected from salts thereof, and an oxidizing agent to dye the hair vividly. , relates to a hair dye composition having good color retention and excellent aging stability.

Conventionally, an oxidation hair dye using an oxidation dye is known as a hair dye, and consists of a first agent containing an oxidation dye and an alkaline agent and a second agent containing an oxidizing agent such as hydrogen peroxide. A two-agent type is widely used.

In such a two-component oxidative hair dye, the oxidative dye permeates into the hair and undergoes oxidative polymerization to dye the hair. At the same time as hair dyeing, the alkaline agent contained in the first agent decomposes the oxidizing agent contained in the second agent and generates oxygen to decompose and decolor melanin in the hair. possible to raise. Therefore, the oxidative hair dye has a high dyeing effect, has a good color retention, and can be dyed brightly, but has a problem that it is difficult to express a vivid color tone.

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

Further, in Patent Document 2, two types of solutions, a first liquid containing an acidic direct dye, an alkali and a polymer-based thickener, and a second liquid containing hydrogen peroxide and having a pH of 4 or less are mixed. , pH 9.0 or higher and a hair bleaching/dyeing method in which a composition having a specific viscosity is applied to the hair.

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

Patent Document 3 also reports a hair dye composition containing specific amounts of an oxidation dye intermediate, an acid direct dye and an oxidizing agent. In this composition, it is possible to express a vivid color tone while brightening the hair, but the acid direct dye is decomposed by the antioxidant added to prevent oxidation polymerization of the oxidation dye, and it is stable over time. There is a problem that it is not excellent in sex.

After leaving these yak hair bundles for 30 minutes, they were washed with water and air-dried to complete the dyeing treatment of the yak hair bundles. The dyed yak hair tresses were evaluated as follows.
The dyed yak hair bundle was visually observed, and the color tone was evaluated as follows: (5) very vivid color tone, (4) vivid color tone, (3) somewhat vivid color tone, (2) slightly insufficient vividness, ( 1) The color tone was sensory-evaluated on a 5-grade scale of insufficient vividness. In some cases, such as 3.5, an intermediate evaluation is performed.
