Glycerin freezing point
In food and beverages, glycerol serves as a humectant, solvent, and sweetener, and may help preserve foods. It is also used as filler in commercially prepared low-fat foods (e.g., cookies), and as a thickening agent in liqueurs. Glycerol and water are used to preserve certain types of plant leaves.

WebHomeowners in Georgia need to be alert to the danger of freezing and bursting water pipes when the outdoor temperature threatens to drop into 20-30 °F range. This threshold is primarily for homes where sub-freezing outdoor temperatures may occur a small number of times each season. Water has a unique quality in that it expands as it freezes.
WebNote: * Due to the unique metastable behavior of glycerol around its freezing point, its freezing point is not necessarily the same as its melting point. ** There are a few studies reporting the cetane number of glycerol at this moment, but it needs to be addressed by more studies to establish a general consensus in the field of research.
