Description

[Detailed description of the invention] Oxidizing hair dye consisting of a liquid coloring agent and an emulsified oxidizing agent-containing composition, and hair oxidation staining method The present invention provides a liquid coloring agent and a C1 to C24 natural or synthetic aliphatic aliphatic aliphatic acid. containing 2.5 to 12 weight percent of at least one alcohol and an oxidizing agent. The emulsified compositions are mixed in a ratio of 1:1.5 to 1:4, respectively. The present invention relates to an oxidative dyeing agent for hair obtained thereby, and a method for oxidative dyeing hair.

Hair oxidation dyes are as important today as ever in the field of hair treatment. It is a component. It consists of two components. These ingredients should be prepared immediately before use. It is mixed with and applied to the hair to be treated.

The first component, ie, the coloring agent, contains a substance that has a coloring effect. This is a liquid, It is available in the form of a bottle or an emulsion. The second component contains a suitable oxidizing agent. It is available in the form of an aqueous solution, cream or powder.

In this case, the dyeing is carried out using a specific developer component in the presence of a suitable oxidizing agent, for example hydrogen peroxide. This is done by reacting specific coupling components. As a color developing component 1,4-diaminobenzene, 2,5-diaminotoluene, 2,5-diamino Phenylethanol, 4-aminophenol and 4-amino-3-methylphenol Nord is used. For coupling components, for example, resorcinol, 4-chlorresorcin, sesame oil, 2-methylresorcin, 3-aminophenol , 4-(2'-hydroxyethyl)amino-1,2-methylenedioxybenze and 2-amino-4-(2°-hydroxyethylamino)-anisole are Commonly used.

In some countries, for example in the United States, liquid coloring agents are mainly used. I'm tired. Liquid coloring agents are given considerable importance in publications.

This is due to the advantages that the raw materials contained in this product are easily available in terms of price, and Liquid materials have the advantage of being technically easy to manufacture.

In carrying out dyeing, the liquid coloring agent is usually a hydrogen peroxide aqueous solution and, for example, 1: They are used as a mixture at a ratio of 1:1 or 1:2. Color former and hydrogen peroxide solution The mixture is prepared, for example, by pouring it into an application bottle and immediately applied to the hair to be dyed. is applied to.

However, liquid color formers have major drawbacks. In other words, the liquid coloring agent is hydrogen peroxide. When mixed with a solution, it quickly turns black. Also, the application of this oxidative hair dye The clothed hair is dyed very slowly while in contact with the hair dye. but The hair dye may be washed out too early because the oxidative hair dye is already blackened. As a result, the action time on the hair is too short and the desired concentration is not achieved. A defect occurs in that the dye is not dyed.

Furthermore, commonly used liquid coloring agents contain ammonia that is extremely strong. It also has the disadvantage of producing an unpleasant odor because it is easily released. That way Liquid hair dyes, especially those in light shades, can cause unwanted irritation to the scalp. It is known that Therefore, the present invention utilizes a known liquid method for oxidative hair dyeing. An oxidative hair dye based on a liquid color former that does not exhibit the above-mentioned drawbacks of color formers. and a method for oxidative dyeing hair using the oxidative hair dye. I set out with this as a challenge.

Here, the liquid color former is obtained by mixing an oxidizing agent-containing emulsified composition. The oxidizing hair dye that is used in this product does not cause any problems to the scalp, and it can be used at an early stage after mixing the oxidizing agent. It does not cause any darkening that would adversely affect the staining results, and it is It was found that the unpleasant odor caused by released ammonia was significantly lower than that of Chino's hair dye. It was.
