Problems solved by technology

The dosage form of existing low-temperature disinfectants is generally binary packaging, which is divided into powder and liquid. The reason is that the corresponding disinfection activity cannot last for a long time after being configured into a solution, and it needs to be prepared and used immediately.
However, the problem still exists in the binary packaging is that the powder storage is easy to agglomerate, and it will still cause a certain decrease in activity
And the patent uses common potassium monopersulfate compound salt, its storage anti-caking performance and activity stability performance need to be further improved

Abstract

The invention belongs to the technical field of low-temperature disinfectants, and discloses a potassium monopersulfate low-temperature disinfectant and a preparation method thereof. The low-temperature disinfectant comprises a liquid single-component system or a double-component system composed of powder and a solution; and the disinfectant comprises the following components: potassium monopersulfate composite salt, a surfactant, organic acid, inorganic buffer salt, calcium chloride, ethanol, ethylene glycol and water. The low-temperature disinfectant disclosed by the invention can be kept in a liquid state at minus 40 DEG C, does not solidify or freeze, can still be sprayed for disinfection, and can still keep a disinfection effect. Sterilization tests are carried out under the normal temperature conditions of 25 DEG C, -18 DEG C and -40 DEG C respectively, and the average killing logarithm values on bacteria and viruses are all larger than 4.00 after the action time of 10 min. The disinfectant has good disinfection capability under the conditions of normal temperature and low temperature.

Description

technical field [0001] The invention belongs to the technical field of low-temperature disinfectants, and in particular relates to a low-temperature potassium monopersulfate disinfectant and a preparation method thereof. Background technique [0002] In recent years, with the spread and spread of infectious viruses such as the new crown virus, the safety of cold chain food has aroused everyone's strong attention. Compared with items at room temperature, it is much more difficult to disinfect items in the cold chain state. Disinfection at low temperatures requires safe and effective disinfectants and reliable disinfection methods. [0003] Conventional disinfectants use pure water as a solvent. Under low-temperature freezing conditions, the liquid disinfectant condenses into a solid state, making it difficult to perform disinfection, and even make these disinfection products completely ineffective. Conventional disinfection methods have clear environmental temperature conditi...
