What Chemicals Are Used in Hand Warmers?

Answer

Hand warmers are small disposable packets that are held in the hand and produce heat on demand to warm cold hands. Packaged hand warmers contain iron particles or powder, salt water, activated carbon, an absorbent material and other chemicals which act as insulators. When the hand warmer pouch is removed from its packaging, oxygen drifts across the pouch’s permeable covering. With water and salt present, the oxygen reacts with the iron powder that is inside to form iron oxide and release heat.
