[labnetwork] Disinfecting Keyboards and Peripherals

[Robert M. HAMILTON]

Mark Heiden,
If you are looking for an alternative to 70% 2-propanol consider "wipes".
There is a product sold to veterinarians for disinfecting animal cages and
surfaces, Pi Quat 20. It is a bacteriacide, fungicide and virucide. I use
it in my greenhouse and my plant tissue culture operations. It is composed
of 20% quaternary ammonium salts, the specific "quats" and their ratio
being identical to the ingredients in Chlorox Disinfecting Wipes but at
higher concentration.  In addition, Chlorox wipes  a small amount of
Ethylene glycol monohexyl ether. The Ethylene glycol monohexyl ether
presumably acts as a solvent to dissolve oils which might mask surfaces
from an aqueous solution. The combined concentration of quats in
Chlorox Wipes is 0.368% versus 20% in Pi Quat 20. Attached are SDS
.pdf's and appended are photos of Chlorox Wipes.
