Food grade CMC Use in Reusable Ice Packs
Food grade CMC is sometimes used to make reusable ice packs. When combined with water and other substances such as propylene glycol, Food grade CMC forms a eutectic mixture--a mixture whose freezing point is lower than that of any of the mixture constituents. One product on the market has a freezing point of -23 degrees Celsius (-9.4 Fahrenheit). These reusable ice packs are usually nontoxic and environmentally friendly.
