They can last 12-36 hours in a cooler depending on the ice pack and quality of the cooler. Gel ice packs DO NOT last as long as ice but warm up faster due to their lower melting point.
Is ammonium nitrate banned?

Why is ammonium nitrate used in cold packs?
In the water is another plastic bag or tube containing ammonium-nitrate fertilizer. When you hit the cold pack, it breaks the tube so that the water mixes with the fertilizer. This mixture creates an endothermic reaction — it absorbs heat.
Is calcium ammonium nitrate explosive?
Calcium ammonium nitrate with less then 0.2% combustible substances has no explosive properties. However, this alkali nitrate does not contain groups that may react with oxygen, thus is not expected to propagate combustion along a test substance pile, and is therefore considered not flammable.
What ice lasts the longest?
Cubed ice is the most common and readily available ice, yet will last slightly less than blocked ice. In our results block ice will last about a half of a day longer. However, internal temperature on cooler contents will be higher, as there is less surface area contact between contents and ice as compared to cubed ice.
Can you put ice pack gel down the drain?
The company does not recommend putting the thawed gel down the sink or septic tank because, while it is nontoxic and non-hazardous, it can further clog the pipes if there is a pre-existing clog.

Is the gel in cold packs toxic?
The gel in most freezer packs is non-toxic and biodegradable; it is usually a polymer or cellulose. … If this gel comes into contact with a child’s eyes, it may cause mild irritation. If you notice that your child has ingested some of the gel, do not panic.
