Abstract

The invention provides a kind of porous Ni-La / foam metal material doped with sulfur as the cathode, and the inert metal material as the anode, through the ion exchange membrane, the electrolytic cell is divided into an anode chamber, an intermediate chamber and a cathode chamber, and the middle The mixed solution of potassium carbonate, potassium bicarbonate and purified water is introduced into the room, the water is purified into the cathode chamber and the anode chamber, and the power is turned on for electrolysis to obtain a fungicide. The pH of the fungicide is 12.5±0.3, and no surface activity is added. Antiseptics, preservatives or other additives, the main components are purified water and trace mineral elements, and the cleaning effect of the bactericides is >99.9%.

Description

technical field [0001] The invention relates to a method for preparing a superalkaline bactericide for hand sanitizer, which belongs to the field of preparing superalkaline ionized water by electrolyzing water and being used in the field of bactericides, disinfectants and cleaning agents. Background technique [0002] At present, the disposable antibacterial hand sanitizers on the market are based on various chemically synthesized surfactants. In order to make them have antibacterial functions, various bactericides are added. In order to avoid the damage of various agents to the skin, there are also Different skin care agents will be added, but although these products have a certain decontamination ability, they are relatively sticky after use, and the experience is not strong, and the hazards of the surfactants contained in the products have been widely concerned in recent years. The focus is mainly on the irritation to the mucous membrane, sensitization to the skin, toxici...
