Objective: To find out an agent making glutaraldehyde solution for disinfection both noncorrosive and stable. Methods: Substitute 0.25% nonionic surfactants(N-sf): polyoxylethylene (23) lauryl ether (Brij 35) or polyoxylethylene (10) octylphenyl ether for 3% sodium bicarbonate. Stability of the glutaraldehyde solution for disinfection was tested by constant temperature method under forty

sixty and eighty degrees centigrade (40℃

60℃ and 80℃). In addition

testing the glutaraldehyde solution for disinfection reserved for five months and observing whether it is corrosive on medical appliances or not. Testing method of content of the glutaraldehyde solution for disinfection accords to Standard of Hospital Preparation of China

first edition. Results: The glutaraldehyde solution for disinfection consumed quantity of sulfuric acid titrant among stipulation. Medical appliances immersed in the glutaraldehyde solution for disinfection for five months were smooth and spotless. Conclusion: The glutaraldehyde solution for disinfection is of high stability and noncorrosivie.
