The key to the heat generated from hand warmers is the reaction of sodium acetate. Sodium acetate has been around for centuries, but the exact discovery of it is unknown--however, it was most likely discovered at the same time that acetic acid, or vinegar was founded. Vinegar has been used since 5000 BC by the ancient Babylonians, who used it to slow the action of bacteria in food (as a preservative). Ancient armies, such as Caesar's and Hannibal's sweetened it and consumed it as a beverage. Vinegar was also used during the Black Plague in Europe when people poured vinegar over their skin to protect it from bacteria, as well as a deodorizer. Vinegar was also used in more recent modern times. For example, during World War I, it was used to treat wounds. Today, it can treat rashes and bites, and has become an ingredient in many foods.

Sodium acetate's usage dates as far back as 1898. However, there are no records to show the exact usage of sodium acetate from that long ago. Hand warmers were invented and produced in the 20th century, and since then, the commercial use of the compound has increased dramatically. Sodium acetate has a variety of uses today. It is used in soaps and salts, as well as in textiles. In addition, it is used in foods as a preservative and flavor enhancer. Knowing the historical, as well as modern day uses of sodium acetate can better our understanding of the compound and improve our future use of it.
