Every oil holds a different level of ozone. The amount is determined by the Potential Ozonide Intensity factor. The POI is measured using the amounts of omega 3, 6 and 9 fatty acids the oil holds. Those with higher omega 9s can hold more ozone.
Store your ozone suppositories in the fridge so they are easier to use and will last longer. Ozonated oils can last as many as ten years refrigerated. Place the jar in the refrigerator for at least an hour before first use.
