preparation example Construction

[0083] The present invention also provides a preparation method of the above-mentioned walnut green skin black hair dye, the preparation method comprising the following steps:

[0084] (1) Prepare hair dye I agent;

[0085] (2) Prepare hair dye II agent.

[0086] Wherein, in step (1), the penetrating agent, complexing agent and part of thickener are dissolved in deionized water; In ionized water, after stirring evenly, the hair dye I agent is obtained.

[0087] Preferably, when multiple thickeners are used, the thickener with a slow dissolution rate is preferentially dissolved, and then the thickener with a fast dissolution rate is dissolved. For example, when sodium carboxymethyl cellulose and hydroxyethyl cellulose are used as thickeners, sodium carboxymethyl cellulose can be dissolved first, and then hydroxyethyl cellulose can be dissolved.

[0088] More preferably, when dissolving the penetrating agent, complexing agent and slow dissolving thickener in deionized water, ...

Description

technical field [0001] The invention relates to a black hair dye, in particular to a black hair dye containing natural hair dye components in green walnut peel. Background technique [0002] Walnut is one of the common nuts, which is abundant in my country and has a wide planting area. According to reports, in 2013 China's walnut cultivation area was 2.533 million hectares, with an annual output of 2.325 million tons. In recent years, China's walnut cultivation area has been increasing at an annual rate of 10%. It is expected to reach 2.67 million hectares in 2020, and the annual output will reach 3 million tons by then. [0003] The walnut green skin is wrapped outside the walnut, and the walnut green skin that is taken off after the walnut is harvested is often discarded at will, has not been fully utilized, and will cause resource waste and environmental pollution. If the walnut green husk is used, it can not only reduce resource waste and environmental pollution, but a...
