Mechanism of Action
The active ingredient of SteriCold cold chemical sterilant is peracetic acid; it acts on the lipid membranes, DNA and other components essential to the life of the cell. Baldry and Fraser in S.S. Block 4th ed. page 176 describes in detail that it is the peracetic acid (active oxygen), the active ingredient that interrupts the chemiosmotic function of the cytoplasmic membrane lipoprotein and transport into the cell through a shift or break the cell wall. Besides its characteristic of denaturing protein may explain its excellent sporicidal action.

Biocidal activity
Peracetic acid (active oxygen), which is formed by the reaction of hydrogen peroxide (freed from the sodium perborate dissolved in water) and tetraacetyletilendiammina (TAED), according to the reaction scheme shown above gives SteriCold cold chemical sterilant considerable biocidal activity on:
- Spore
- Virus (including hepatitis B and HIV)
- Bacteria (Mycobacterium tuberculosis, TB)
- Fungi

 The formulation, on the basis of this activity, performs the function of decontaminant and disinfectant high level (chemical sterilant cold).
