Glycerin in water freezing point

WebFor many heat-transfer applications it is necessary to use a heat-transfer fluid with lower freezing point than water. The most common antifreeze fluid - ethylene glycol - must not be used where there is a chance of leakage to potable water or food processing systems. In food processing systems the common heat-transfer fluid is based on propylene glycol. http://aciscience.org/docs/Glycerine_-_an_overview.pdf
