Problems solved by technology

[0002] Chlorhexidine acetate has long been recognized internationally as an intermediate-effect disinfectant, but chlorhexidine acetate is white or almost white crystalline powder, which is insoluble or slightly soluble in water, and only soluble in alcohol or alcoholic solutions similar to alcohol. Therefore, the disinfectant containing chlorhexidine acetate generally contains alcohol or alcohol-like alcohol solution. As we all know, if the disinfectant containing alcohol or alcohol-like disinfectant is directly sprayed on the mucous membrane or skin of the human body, especially the suppurative or festering The surface of the skin will irritate the mucous membrane or skin, which limits the use of disinfectant to varying degrees
[0003] Chinese invention patent ZL97108543.9 discloses "an antibacterial bactericide and its production process". The antibacterial bactericide is composed of chlorhexidine acetate, ethanol, glycerol and OP emulsifier. and glycerin, so it has strong irritation to the skin
[0004] Chinese invention patent ZL02126050.8 discloses "preoperative skin disinfectant", which is formulated from chlorhexidine acetate, benzalkonium bromide, glycerol, nonylphenol polyoxyethylene ether and distilled water, although its bactericidal Works well, but it contains glycerol, so it's a strong skin irritant
