Washable hair dye and preparation method thereof

Abstract

The invention discloses a washable hair dye and a preparation method thereof, and belongs to the field of preparation of cosmetics. The washable hair dye contains an agent I and an agent II, wherein the agent I is prepared from the following components in percentage by mass: 0.25 to 5 percent of graphene, 5 to 10 percent of graphene stabilizer, 0.5 to 2.5 percent of ascorbic acid, 1 to 3 percent of propyl gallate, 5 percent of glycerol, 2 to 5 percent of thickener and the balance of water; the agent II is prepared from the following components in percentage by mass: 5 to 10 percent of ferroussulfate, 0.1 to 0.5 percent of the ascorbic acid, 5 percent of the glycerol, 1 to 5 percent of alkaline agent, 2 to 5 percent of the thickener and the balance of water. The washable hair dye disclosedby the invention has the beneficial effects that dyes such as the graphene and the graphene stabilizer are synergized and reasonable ratio is designed, so that the obtained hair dye has the characteristics of good color fastness, low possibility of fading, anti-static property and the like. The washable hair dye is tested by an experiment to indicate that hairs are still kept bright black after 70 times washing.

Description

technical field [0001] The invention relates to the field of cosmetic preparation, in particular to a washable hair dye and a preparation method thereof. Background technique [0002] Hair dyeing is one of the most common means of modern make-up.

Problems solved by technology

[0004] In order to overcome the problems of harmfulness to human body, irritation to skin, and easy fading of existing hair dyes in the prior art, one of the purposes of the present invention is to provide a washing-resistant hair dye, which uses graphene oxide, a new material, as the main raw material , adding a small amount of auxiliary materials to the hair dye, adding a graphene stabilizer that can participate in the hair dyeing reaction during the graphene oxide reduction process, and the prepared hair dye still maintains a black luster after 120 times of washing. The specific scheme is as follows:
