Frequently Asked questions
HotHands warmers are made of natural materials including iron powder, water, salt, activated charcoal and wood fiber. Once removed from the specially designed outer packaging the exposure to air activates the ingredients and the warmer begins to build heat. Always allow 10 to 20 minutes for the warmers to reach their optimal temperatures.
What are HotHands® warmers made of and how do they work?
Our HotHands® family of air activated warmers all contain a mixture of natural ingredients that when exposed to air react together to produce heat. This is accomplished through an extremely fast oxidation process. Ingredients include: iron powder, water, salt, activated charcoal and vermiculite. HotHands® has perfected the process so that our warmers, depending on the individual product, produce heat anywhere from 100°F to 180°F for duration of 1 to 20+ hours.
