Industrial grade PG has low toxicity and low vapor pressure. It should be stored at ambient temperatures in a closed container away from sources of UV light. When properly stored, it has a shelf life of a year or more. Overheating can lead to accelerated degradation — temperatures should be controlled during use, transport, and storage, and they should not exceed 40 degrees Celsius.
