Problems solved by technology

Its shortcoming is: the selenium disulfide purity that this method prepares is on the low side
Its disadvantages are: to vacuum seal the tube, it is necessary to vacuum the inside of the quartz tube to below 10-5Pa and then calcinate and seal it, which requires high equipment
The amount of quartz tube is less, and the production capacity of a single batch is low; the quartz tube is a consumable product, which produces a lot of quartz waste, and the overall production cost is high

Abstract

The invention provides selenium sulfide composite powder for hair washing. Selenium sulfide is uniformly dispersed on the surfaces of nano microspheres in a nano form, can be directly mixed with a hair washing composition for use, is not easy to settle and separate in the composition, does not need to be mixed with a shampoo during use, and is simple and convenient. Carbon sphere particles can be used as an active carbon shampoo additive, can reduce generation of scurf and reduce grease secretion, and have an obvious inhibition effect on malassezia.

Description

technical field [0001] The invention belongs to the field of daily chemicals, and in particular relates to a selenium sulfide composite powder for shampooing. Background technique [0002] In daily life, affected by stress and environmental pollution, more and more people are troubled by problems such as dandruff, scalp itching, and scalp inflammation. Most of the anti-dandruff products on the market currently use pyridine sulfate as the anti-dandruff agent, but this There are disadvantages of anti-dandruff agents. Pyridine sulfate is highly irritating, insoluble in water and difficult to dissolve in organic solvents. When it is used in shampoo, it is prone to poor compatibility with other components, difficult to disperse, and easy to precipitate and agglomerate. Lead to unstable anti-dandruff effect. The existing technology uses plant extracts as anti-dandruff agents, which are mild and non-irritating. However, the components of plant extracts are complex, the active ingr...
