What are the cold discs in ThermaCare® Cold Wraps?

The cold discs are the part of ThermaCare® Cold Wraps that provide cooling. These cells contain a mixture of ingredients that stay cold when frozen. Water is the main ingredient that provides the cooling effect when frozen; a thickening agent keeps the water uniformly distributed within the cell; the blue dye is for aesthetics; and the preservative keeps things from growing inside the discs.
