Embodiment Construction

[0029] The present invention will be further described below through specific embodiments. The following examples are preferred implementation forms of the present invention, but the implementation manners of the present invention are not limited by the following examples.

[0030] The raw materials used in the present invention are all derived from commercially available products.

[0031] The preparation method of embodiment and comparative example hair dye:

[0032] The production process of the first agent:

[0033] Heat the oil phase and water phase to 75°C respectively, then add the oil phase to the water phase, and emulsify homogeneously for 3-5 minutes. Dissolve dye intermediates, antioxidants, etc. in some water, and add them to the emulsion. Finally, essence, ammonia water, platinum nanoparticles, etc. are added in sequence. Stir until smooth, then fill.

[0034] The production process of the second agent:

[0035] Heat the oil phase and water phase to 75°C resp...

Abstract

The invention discloses a hair dye which is prepared from the following components: a first agent and a second agent. The first agent is prepared from an oxidation dye, an alkaline agent and nanometermetal particles with an anti-oxidation effect; based on the weight of the whole first agent, the content of the nanometer metal particles with the anti-oxidation effect is 0.001 to 100ppm, the content of the oxidation dye is 0.01 to 5 percent, and the dosage of the alkaline agent is used for adjusting the pH to range from 8.0 to 11.0; the second agent is prepared from hydrogen peroxide with the content being 3 to 12 percent. The hair dye provided by the invention has the advantage of good hair dyeing effect.

Description

technical field [0001] The invention relates to the technical field of daily chemicals, in particular to a hair dye and its application method. Background technique [0002] Oxidative hair dyes are usually composed of two agents. The first agent contains alkali agents, antioxidants, oxidation dyes, etc., and the second agent is mainly hydrogen peroxide. Before use, the two agents need to be mixed, and then evenly applied on the hair. The oxidation dye in the first agent is oxidatively polymerized under the catalysis of hydrogen peroxide to develop color. At the same time, the hydrogen peroxide in the second agent decomposes the melanin in the hair under alkaline conditions to fade the hair color, and then dye the desired color. The dye intermediates have a smaller molecular weight and can penetrate into the fur cortex, and the reaction products produced between them are retained in the cortex and are not easily washed off. [0003] Even so, however, the color tends to fade...
