Embodiment 1
[0018] Weigh a certain amount of deionized water, heat it to 70°C, add lipid, add surfactant after it is completely dissolved, stir mechanically for 30 minutes, and rotate at 500 rpm; then lower the temperature to 45°C, add antioxidants in turn , chelating agent, and alkaline agent and stirred for 25 minutes, then added hydrogen peroxide and organic solvent, and stirred for 5 minutes; ③ After adding the melanin precursor and stirred for 15 minutes, added mordant and stirred for 10 minutes; ④ Increased the stirring speed to 1200 rpm, and added thickener, and the system was replenished with water and stirred for 30 minutes to obtain a single-dose hair dye.
Embodiment 2
[0020] Weigh a certain amount of deionized water, heat it to 80°C, add lipid, add surfactant after it is completely dissolved, stir mechanically for 20 minutes, and rotate at 800 rpm; then lower the temperature to 45°C, add antioxidants in turn , chelating agent, and alkaline agent and stirred for 20 minutes, then added hydrogen peroxide and organic solvent, and stirred for 4 minutes; ③Added plant dye and melanin precursor and stirred for 12 minutes, then added mordant and stirred for 8 minutes; ④Increased the stirring speed to 1500 rpm / min, add a thickener, and the system is replenished with water and then stirred for 25 minutes to obtain a single-dose hair dye.
[0021] 2. Comparison test of hair dyeing temperature
Embodiment 3
[0023] Prepare a black single-dose hair dye according to the above preparation method, dye 5 strands of white hair at 25°C (normal temperature), 30°C, 35°C, 40°C, and 45°C, and wash the hair strands after 30 minutes Compare coloring situations.

Abstract
The invention belongs to the field of special cosmetics, and particularly relates to a preparing method for single-agent hair dye and a hair dyeing method. The preparing method for the single-agent hair dye includes the following steps that certain amount of deionized water is weighed and heated to 70-80 DEG C, lipid is added, and after the lipid is completely dissolved, a surfactant is added and mechanically stirred for 20-30 min; the temperature is lowered to 40-55 DEG C, an antioxidant, a chelating agent and an alkaline agent are sequentially added and stirred for 20-30 min, and hydrogen peroxide and organic solvent are added and stirred for 2-5 min; a melanin precursor is added and stirred for 10-15 min, and a mordant is added and stirred for 5-10 min; the stirring speed is increased, a thickening agent is added, and stirring is carried out for 20-30 min after water is supplemented to the system to obtain the single-agent hair dye. The preparing process is simple and easy to operate, the prepared single-agent hair dye is high in stability and capable of being stored for 6 months in a sealed mode at the normal temperature, the hair dyeing time is shorter, and the hair dyeing temperature is low.
Description
technical field [0001] The invention belongs to the field of special cosmetics, and in particular relates to a preparation method of a single-dose hair dye and a hair dyeing method. Background technique [0002] Hair dyes refer to cosmetics that can change the color of hair and have special uses. Hair dye can be divided into hair dye powder, hair dye lotion and hair dye cream according to the form, can be divided into single-dose type and two-dose type according to the dosage form, and can be divided into: oxidative hair dye and non-oxidative hair dye according to the dyeing principle. According to the formula and the length of attachment time, hair dyes can be divided into three types: temporary, semi-permanent and permanent. Temporary hair dyes mainly include IPL shampoo, color conditioner and hairspray; semi-permanent mostly refers to plant-based hair dyes such as liquid and paste; permanent hair dyes belong to oxidation dye hair dyes, which are extremely rich in color a...
