Preparation method of anti-dandruff shampoo

Abstract

The invention provides the preparation method of the anti-dandruff shampoo, the shampoo prepared by the method has washing and caring functions, can endow hair with excellent wettability and combability and enables the hair to be glossy, smooth, moist and smooth, selenium sulfide is prepared by a one-step method, and the yield and efficiency of the shampoo are far higher than those of like products.

Description

technical field [0001] The invention belongs to the field of daily chemicals and relates to a preparation method of a shampoo composition. Background technique [0002] Shampoo is a product mainly composed of surfactants, which can clean human scalp and hair and maintain its beauty. It is a daily chemical product that is widely used by the people in their daily life. The components of shampoo include cleaning agents, hair care ingredients, hair oils, conditioners, anti-dandruff and anti-itch agents, preservatives, thickeners, chelating agents, thickeners, ultraviolet absorbers and nutrients, etc., shampoo The main effective substances are generally anionic surfactants. Appropriate surfactants can achieve the effect of rich foam, low irritation, high cleaning degree but weak degreasing power. [0003] Earlier, people used shampoo to clean their hair. With the improvement of living standards, people began to require it to have multiple functions, such as anti-dandruff, making...

[0006] 2. Sebum secretion Excessive sebum secretion is also a major reason for the abnormal proliferation of Malassezia, but if the sebum secretion is too small, the scalp will also lack protective ingredients, and the water-locking function is insufficient, which can easily lead to dry scalp, itching, and serious It can also cause scalp inflammation or weakening of the scalp barrier

Although the purity is high, the obvious preparation process is extremely complicated. Although the purity is high, the yield is insufficient

[0011] In addition, there is no prior art regarding the electrochemical synthesis of selenium sulfide, but the preparation method of selenium simple substance by electrochemical synthesis, such as CN202110797078 discloses a selenium sulfide composite powder for shampoo, the selenium sulfide is uniformly dispersed in nanometer form On the surface of nano microspheres, it can be directly mixed with the shampoo composition, and it is not easy to settle and separate in the composition. It is not necessary to mix selenium sulfide and shampoo during use, which is simple and convenient. Carbon sphere particles can be used as activated carbon shampoo Additive, can reduce dandruff, reduce oil secretion, and has obvious inhibitory effect on Malassezia, the principle of electrochemical deposition is 6H + +SeO 3 2- +4e - →3H 2 O+Se, then prepare selenium sulfide by sulfidation, then remove excess sulfur by sublimation sulfur, obtain high-purity selenium sulfide, but known in the art in sublimation sulfur separation and selenium sulfide process, can cause the loss of part of selenium sulfide, And the whole preparation process is to obtain selenium first, and then obtain selenium sulfide, the process is obviously not a one-step synthesis
