25%-100% DOWFROST™ food grade propylene glycol heat transfer fluid includes a specially designed package of industrial corrosion inhibitors

Solutions have an operating temperature range of -50° F to 250° F (-46° C to 121° C), and the glycol fluid is water white (colorless).

What Does it Mean to be a Food Grade Antifreeze (or Food Safe Antifreeze)? 

25%-100% DOWFROST low tox antifreeze is made from USP/EP grade propylene glycol and food grade phosphate. These two ingredients are recognized by the FDA as food safe.

Based on this regulatory status and the long history of satisfactory use, Dow® certifies that DOWFROST inhibited propylene glycol is acceptable for use as a heat transfer fluid where contact with drinking water is possible or food processing applications where accidental contact with food or beverage products could occur.
