Embodiment Construction

[0028] The protective agent against hair dye allergy can be applied to the hair dye containing p-phenylenediamine, wherein the ratio (by weight) of the hair dye to the protective agent can be 1:1.0-2.0. A better ratio is 1:1.5.

[0029] In the preparation of the protective agent against the excessive consumption of hair dyes, the method of plant purification is as follows: firstly, the plants to be purified are washed, water-cut at room temperature, and dried; Ionized water mixture, the ratio of butanediol and deionized water is 2-4: 6-8 (that is, butanediol is 20-40%, and the rest is deionized water), made into an aqueous extract, at 60-80 Extract at ℃ for 8 hours; finally reduce the pressure and remove the solvent at 20℃ to obtain the extract, which is dissolved in 0.001-0.1% potassium persulfate and 0.002-0.2% sodium persulfate solution with a ratio of 1:1.

[0030] In the research of the present invention, an animal model has been established, the curative effect a...

Description

【Technical field】 [0001] The invention relates to the field of hair dye and anti-hair dye allergy protective preparations, in particular to a protective agent, hair dye and method for anti-hair dye allergy sensitized to phenylenediamine (PPDA). 【Background technique】 [0002] With the improvement of material living standards, people's demand for beauty is getting higher and higher. Middle-aged and elderly people like to dye their hair black in order to maintain their youth. In recent years, colored hair dyeing, balm and colored wigs have become the beauty fashion pursued by more and more young people. However, since hair dye is based on p-phenylenediamine (PPDA), PPDA itself has strong sensitivity (sensitization rate can be as high as 10%) and can cross allergies with other substances (such as azo, Aniline dyes, local anesthetics (procaine, benzocaine), and sulfonamides, etc.). At the same time, because p-phenylenediamine has the characteristics of firmly combining with h...
