Abstract

The invention relates to a preparation method of a hair dye, especially to a preparation method for a botanical hair dye, and specifically relates to a preparation method for a hair dye based on a walnut green husk pigment. The preparation method comprises the following steps: striping walnut green husk, air drying in a shady place; crushing, sieving through a sieve of 70-90 meshes; adding green husk powder and acetone into a container with a solid-liquid mass ratio of 1:25-35 and an acetone concentration of 70-90%, oscillation processing the solution at a constant temperature of 40-50 DEG C for 10-14 h; centrifuging the solution for 2-4 times, filtering off impurities and collecting the supernatant; decompressing concentrating the solution at a temperature of 50-65 DEG C to obtain an ointment; and preparing the hair dye according to the following material ratios: 5-7% of the ointment, 85-87% of water, 0.5-1.5% of silicone oil, 0.5-1.5% of oil-solubility VE, 0.5-1.5% of VB, 3-5% of olive oil and 0.5-1.5% of white vaseline. The preparation method is simple, easy to operate and high in recovery rate. The prepared green husk pigment is granular, shows yellow under the developing effect of methyl red, has no escherichia coli, is suitable for exploitation of the hair dye, and helps to solve the problems that the conventional hair dye contains carcinogenesis substances and the natural hair dye is not exploited fully.

Description

technical field [0001] The invention relates to a preparation method of a hair dye, in particular to a preparation method of a plant source hair dye, in particular to a preparation method of a hair dye based on walnut green peel pigment. Background technique [0002] Walnuts belong to the genus Juglandaceae, and the scientific name is Juglans ( Juglans regia L .), my country's walnut planting area has reached 31.75 million mu, with an annual output of nearly 500,000 tons. The total planting area, annual output and green peel waste rank first in the world. Walnut green peel contains green pigments such as purple and green pigments. There are records of using walnut green peel to dye cloth in ancient times, and the fact that green peel pigment is used to dye hair also exists. At present, hair dye has become the fastest growing and most powerful product in the hair care industry. At this stage, my country has become the largest country in the world in the production and sales ...
