Problems solved by technology

[0003] As a means of alleviating ammonia irritation, ethanolamine, trometamol, arginine, etc. are used instead of ammonia in part to reduce the amount of ammonia used, or ethanolamine, sodium silicate, and sodium metasilicate are used, but there are staining power and decolorization The problem of increased scalp irritation caused by remaining on the scalp when the power is low or in large quantities

preparation example 1

[0036] Examples 1-7 and Comparative Examples 1-4 were prepared according to the compositions in Table 1-2 below (unit weight %).

[0037] Esters use triacyl palmitate, triacyl myristate, triacyl stearate, triacyl palmitate, tritetradecyl palmitate, cetyl alcohol Palmitate and stearyl palmitate did not meet the requirements of the present invention and were used as components of a comparative example. As wax, beeswax and candelilla wax are used. In addition, the oxidation dye precursor uses p-phenylenediamine, the coupling agent uses m-aminophenol, the alkalizing agent uses ammonia water (28%), the metal disintegrant uses edetate disodium, and the oxidizing agent uses hydrogen peroxide (35%) ).

Abstract

The present invention relates to an oxidative hair dye composition and, more specifically, to an oxidative hair dye composition which contains at least one kind of ester having 30 or more carbon atoms, thereby suppressing the volatilization of ammonia and thus reducing eye and nose irritation.

Description

technical field [0001] The present invention relates to an oxidative hair dye composition, in particular to an oxidative composition containing at least one long-chain ester having more than 30 carbon atoms, thereby inhibiting the volatilization of ammonia and reducing the resulting irritation to eyes and nose. Hair dye composition. Background technique [0002] For dyeing and decoloring of hair, a two-part type hair dye or decoloring agent consisting of a first agent containing a dye and an alkalizing agent and a second agent containing hydrogen peroxide is generally used. Ammonia is often used in common hair dyes or decolorizers as an alkalizing agent that swells hair and promotes the decomposition of hydrogen peroxide to cause an oxidation reaction. A highly volatile alkalizing agent, ammonia, produces a pungent odor of ammonia when the first and second doses are mixed or applied to the hair, thereby inducing irritation to the nose and eyes. [0003] As a means of allev...
