Further notes on Crotoxyphos

These are descriptions rather than measured values, so they are kept out of the table above and quoted here with the source that reported them.

Corrosivity

Slightly corrosive to copper, lead, mild steel, tin and zinc, but will not attack fiberglass, reinforced polyester, rigid PVC, or the usual lacquers used for lining drums. Incompatible with most mineral carriers, except synthetic silicas such as 'Colloidal Silica K320' and 'Hisil 233'.
