Wherein, in the step (1), the penetrating agent, the complexing agent and part of the thickening agent are dissolved in deionized water; dissolving the walnut green husk extract, the synergist, the color developing agent and the rest of the thickener in the deionized water, and uniformly stirring to obtain the hair dyeing agent I.
Preferably, when a plurality of thickeners are used, the thickener having a slow dissolution rate is dissolved preferentially, and the thickener having a fast dissolution rate is dissolved again. For example, when sodium carboxymethylcellulose and hydroxyethylcellulose are used as thickeners, the sodium carboxymethylcellulose can be dissolved first and the hydroxyethylcellulose can be dissolved.
More preferably, when the penetrant, the complexing agent and the thickener having a slow dissolution rate are dissolved in deionized water, the solution is heated with stirring to accelerate the dissolution of the solute. Preferably, the heating temperature is not more than 90 deg.C, so as to avoid the oxidative degradation of some components.
After heating, the solution is preferably cooled to room temperature, and then walnut green husk extract, synergist, developer and thickener with high dissolution rate are added to prevent the reductive substance from degrading or oxidizing under heating.
In step (2), the metal stain is dissolved in 1/5-1/3 deionized water. The remaining deionized water is dissolved with the thickener and emulsifier, preferably by heating, to increase the rate of dissolution.
Because the metal coloring agent, especially the ferrous coloring agent, is easily oxidized and converted into the trivalent under the heating condition, the color of the complex of the trivalent iron and the coloring agent in the coloring agent I is not black. Therefore, the hair dyeing agent II is preferably prepared by adding the solution dissolved with the metal coloring agent after the solution dissolved with the thickening agent and the emulsifying agent is cooled to room temperature so as to avoid the oxidation of the metal coloring agent and stirring the solution uniformly.
The room temperature in the invention means that the indoor temperature is 20-35 ℃.
In the step (2), the metal coloring agent is separately dissolved and then added into the solution in which the thickening agent and the emulsifying agent are dissolved, so that the metal coloring agent can be fully dispersed without aggregation.
The preparation method of the walnut green husk black hair dye provided by the invention has the advantages of few steps, simple preparation, high reproducibility and small difficulty in industrial quantitative production.
