Comparison of the Activities and Stabilities of Alkaline Glutaraldehyde Sterilizing Solutions

: The sporicidal activities and shelf life stabilities of three alkaline glutaraldehyde-containing sterilizing solutions were evaluated. The time required to reduce a population of spores by one log is the D-value. The test methods employed were the D-value and survival rates. Sporicidin, a new preparation containing a phenolic buffer, was both more stable and more active against test spores than two other test agents, Cidex and Cidex-7.
