Sterilization principle: Aldehyde disinfectant to the microorganism's killing function mainly relies on the aldehyde base, this kind of medicaments mainly acts in the bacterium body albumen the sulfhydryl, the hydroxyl, the carboxyl group and the amino, may make it alkyl, causes the protein solidification causes the bacterium death.
① Glutaraldehyde is a broad-spectrum, efficient disinfectant, can kill all microorganisms;
② Glutaraldehyde can be used for the sterilization of heat-resistant medical devices;
③ Glutaraldehyde in the use of concentration, with a small irritant, low corrosion, safe and low toxicity;
④ Glutaraldehyde is affected by organic matter, and 20% of organic compounds have little effect on germicidal efficacy.
