Abstract

The invention discloses a surface active agent containing selenous anions and a preparation method and application thereof, and belongs to the technical field of the daily chemical industry. The surface active agent is benzyl selenium-alkyl sulphate, the structural formula is C6H5CH2Se(CH2)nSe(CH2)nSO4-M+, wherein n in the formula is an integer from 2 to 4, and M+ is one of a sodion or a potassiumion or an ammonium ion. The surface active agent containing selenous anions is mild in synthesis condition, no special equipment requirement is needed, the energy consumption is low, and raw materials are easy to obtain; the liquid interface activity of the surface active agent containing selenous anions is better than the gas-liquid surface activity, the excellent dynamic foaming performance isachieved, the surface active agent containing selenous anions has the better oxidation resistance and free radical removal capability compared with a surface active agent containing single selenium atoms, and the cytotoxicity, the aquatic organism acute toxicity and the skin irritation are low.

Description

Technical field

[0001] The invention belongs to the technical field of daily chemical industry, and specifically relates to a diselenide-containing anionic surfactant, and a preparation method and application thereof. Background technique

[0002] Selenium (Se) is an element with important physiological activity. It exists in the form of selenoprotein in living bodies and is often the active center of selenoprotease. Selenium deficiency in the human body can lead to serious diseases. Oral oral organic selenium-enriched sugars or protein substances are often the way to supplement selenium, but the safety risk is higher because most inorganic selenium compounds and organic selenium compounds have strong oral toxic and side effects. The inflammatory reaction of human skin often results in the formation of free radicals and other oxidative species, and selenium-containing substances have good antioxidant effects.

[0003] For this reason, the present invention designs a manufacturing ...
