The chemistry inside HotSnapZ is a safe and self-regulating reaction. The maximum internal temperature reaches 128-130F and typically 115-120F at the surface during normal use. The temperatures that HotSnapZ operate at are considered to be non-burning when used as directed. What is inside a HotSnapZ pack and how does it work? HotSnapZ reusable hand warmers and heating pads contain water, a small metal disc and sodium acetate, a safe food grade salt ingredient. The clicking of a disk within the pad triggers the precipitation of the sodium acetate crystals. When the crystals precipitate, it releases the energy that was required to initially dissolve it and stored in the pouch. The release of energy raises the temperature to a maximum temperature of 130F (54C). The process is theoretically repeatable indefinitely. HotSnapZ are a sodium acetate hand warmer. Are the contents of HotSnapZ safe? Yes. The contents of each HotSnapZ are Safe, Non-Toxic and Non-Hazardous. (Water and Sodium Acetate)
