Description

Composition for oxidative dyeing of hair

The present invention relates to an oxidative hair dye, and more particularly to an oxidation which suppresses volatilization of ammonia water by containing one or more esters having a long carbon of 30 or more, thereby reducing eye irritation and odor irritation. Hair dye composition.

For dyeing or decolorizing hair, a two-part hair dye or a decolorizing agent consisting of a hair dye comprising one dose and two doses of an oxidizing agent containing hydrogen peroxide is generally used. In general, hair dyes or decolorants often use ammonia as an alkali agent which swells hair, promotes decomposition of hydrogen peroxide, and causes an oxidation reaction. Ammonia water is a highly volatile alkaline agent. When one or two doses are mixed or applied to the head, an ammonia-stimulated odor occurs, which causes odor irritation and eye irritation.

As means for alleviating the stimulation of ammonia water, there is a case where one part of ammonia water is replaced with Ethanolamine, Tromethamine, arginine or the like to reduce the amount of use, or use Alkaline amine (Ethanolamine), sodium citrate (Sodium Silicate) and sodium metasilicate (Sodium Metasilicate), etc., but there is a decrease in dyeing power or decolorization power or if it is used in a large amount, it will remain on the scalp. Increase the problem of scalp irritation.

However, in the case of Comparative Example 4 in which the content of the ester was more than 5% by weight, the effect of reducing the odor of ammonia water was excellent, but the stability of the dosage form of one dose was lowered, and the mixed viscosity at the time of mixing with the two agents was lowered.

[Test Example 2] Test tube test

In order to evaluate the ammonia odor stimuli of the hair dye compositions of Examples 1 to 7 and Comparative Examples 1 to 4, evaluation was carried out using a test tube for ammonia water test. The test method is as follows.

After mixing 30 g of the hair dye and 60 g of an oxidizing agent, it was placed in a 500 ml flask and allowed to stand at room temperature for 30 minutes. A test tube for ammonia water test (GASTEC NO. 3HM Ammonia, GASTEC) was attached to the flask, and a pump was pulled to suck in ammonia water. The scale of the color change area was read, and the value was recorded. The results are shown in Table 4.

From the results of the above Table 4, it was confirmed that the hair dye compositions of Examples 1 to 7 and Comparative Example 4 containing the esters of the present invention were compared with Comparative Example 3 containing no esters and the conditions of the present invention were not satisfied.
