The measurement that we use to correlate freeze point depression is a sweetener’s molecular weight: The lower the molecular weight, the greater the effect of freeze point depression. Also interesting to consider is the idea of freeze concentration: as a solution freezes, only pure water crystallizes in to ice, which means the concentration of solutes in the remaining unfrozen water increases, which also means that the freezing point of that water continues to drop as more water turns into ice.
