Abstract

The invention discloses a long-acting disinfectant and a preparation method thereof. The long-acting disinfectant is prepared from sorbitan monostearate, modified nano zinc oxide, a basil extract, trehalose, glacial acetic acid, a stabilizer, ethylene glycol and deionized water. The long-acting disinfectant disclosed by the invention has a good long-acting bacteriostatic effect and still has a good bacteriostatic effect on super bacteria, and by modifying the nano zinc oxide, the dispersing performance and the intermiscibility of the nano zinc oxide in a formula system are remarkably improved, and the bacteriostatic effect can be stably exerted for a long time; the modified nano zinc oxide does not agglomerate in a formula system; and basil extract with an excellent bacteriostatic effect is obtained through enzyme-assisted steam distillation and macroporous adsorption treatment, components with the bacteriostatic effect in basil are reserved in the basil extract, and components without the bacteriostatic effect are removed.

Description

technical field [0001] The invention relates to the technical field of disinfectant, in particular to a long-acting disinfectant and a preparation method thereof. Background technique [0002] In recent years, due to the abuse of antibiotics, the emergence of ultra-fine bacteria, methicillin-resistant Staphylococcus aureus is a common and highly toxic bacteria in clinical practice, and is a representative strain of super bacteria, methicillin-resistant Staphylococcus aureus Not only are they resistant to β-lactam antibiotics, but they are often resistant to quinolones, aminoglycosides, and macrolides. The prevention and control of methicillin-resistant Staphylococcus aureus has become an important topic in the field of disinfection. [0003] At present, chlorine-containing disinfectants are widely used in the market, and they have a good disinfection effect, but they have problems of polluting the environment and residues during use, which widely limits their application. ...
