Example 1

Fig. 1 is a schematic block diagram showing the structure of a system 100 for preparing a gel disinfectant according to the present embodiment. Referring to fig. 1, the present embodiment provides a system 100 for preparing a gel disinfectant, by which a gel disinfectant can be prepared to obtain a gel disinfectant with long shelf life and high stability.
