How long is the shelf life of chlorine-containing disinfectants?

The validity period of chlorine-containing disinfectant after preparation should be less than 24 hours.

The shelf life of anything is related to the preservation environment and conditions. If it is sealed and stored at low temperature, it will not be a problem for a few months or even adults. If it's hot in the open air, not for a day. Because it will volatilize hydrogen chloride and gas, it will soon be ineffective.

Now it is generally advocated to prepare disinfectants, including chlorine-containing preparations. Most disinfectants are volatile. If it is not used immediately after preparation, its effective components will decrease after a certain period of time, thus affecting the disinfection effect.

Extended data:

Chlorine-containing disinfectants dissolve in water to produce hypochlorous acid with bactericidal activity, and its bactericidal effective components are often represented by available chlorine. Hypochloric acid has a small molecular weight, which easily spreads to the surface of bacteria, penetrates the cell membrane and enters the interior of bacteria, causing protein oxidation of bacteria and death of bacteria.

Generally speaking, except hypochlorous acid water, other disinfectants cannot be used for air disinfection. Clean up the pollution source, close the doors and windows, use the hypochlorous acid aqueous solution with the effective concentration of 100mg/L and cooperate with the special aerosol atomizer, and use 10~20ml/m? Dosage, spray disinfection, 30 minutes, can be put into use.
