OPTIM™ Synthetic Glycerine - Freezing Point
Pure glycerine has a freezing point of about 17°C (62.6°F). However, glycerine is seldom seen in a crystallized state because of its tendency to supercool. The presence of small amounts of water within a glycerine-water solution also inhibits crystallization, which may depress its freezing point.
