HotHands hand warmers contain approximately 50% iron powder by weight, within a range of 95 to 120 grams.
Composition of HotHands Hand Warmers
Here's a breakdown of what's typically inside a HotHands hand warmer:
- Iron Powder: The primary component responsible for generating heat. It makes up about 50% of the total weight.
- Activated Charcoal: Helps in the oxidation process by distributing heat.
- Vermiculite: Acts as an insulator and helps to retain heat.
- Sodium Chloride (Salt): Functions as a catalyst in the oxidation process.
- Water: Necessary to initiate the oxidation reaction.

| Component | Approximate Percentage | Weight (Range) | Function |
|---|---|---|---|
| Iron Powder | ~50% | 95-120 grams | Generates heat through oxidation |
| Activated Charcoal | Unspecified | Unspecified | Distributes heat, aids oxidation |
| Vermiculite | Unspecified | Unspecified | Insulates and retains heat |
| Sodium Chloride | Unspecified | Unspecified | Catalyzes the oxidation process |
| Water | Unspecified | Unspecified | Initiates the oxidation process |
How HotHands Work
- The pouch is exposed to air.
- The iron powder reacts with oxygen, causing oxidation.
- This exothermic reaction produces heat.
- The other ingredients in the pouch help facilitate and regulate this process.
Practical Insights
- The amount of iron in a HotHands hand warmer is substantial, accounting for half of its overall weight.
- The exact amount of iron can vary within a specific range but it is consistently the main component in terms of weight.
