Can bacteria grow in propylene glycol?
Both Ethylene and Propylene Glycol break down on exposure to high temperatures. … At these concentrations, bacteria will biodegrade the Propylene Glycol causing rapid growth of bacterial contamination. At levels above 1 and below 20%, some bacteria can survive with limited growth, especially at moderate temperatures.
