Is the coolant inside water cold packs safe?

Yes. The coolant is simply 100% pure water, so even if a pack leaks there is no risk of chemical contamination. Unlike gel packs, there are no chemical additives or dyes—just clean water sealed in durable, food-grade film, safe around food, pharmaceuticals, and other perishable goods.
