Good material compatibility, presence of antirust agent. Contain surfactant cleaners, helps for precleaning. Glutaraldehyde at slightly acidic pH is more stable, more sporicidal and less damaging. Acid stabilized solution not only polymerizes slowly but also kills dried spores within 2-0 minutes. Very active bactericidal, fungicidal, tuberculocidal, virucidal and sporicidal activity. High microbiocidal activity against spores. Effective against B.Subtilis/B.Pumilis., Heat resistant spores like Clostridium tetani are killed. Formaldehyde-acts by alkylation with amino and sulthydryl group of protein and nucleic acids.both are , HIGH-LEVEL DISINFECTANTS. The neutral emulsifying agent stabilizes and increases the activity. A combination is 10 times more lethal than either chemical alone.
