Propylene glycol Propylene glycol is a clear, colorless and hygroscopic liquid. Propylene glycol contains an asymmetrical carbon atom, so it exists in two enantiomers. The commercial product is a racemic mixture.Pure optical isomers can be obtained by hydration of optically pure propylene oxide.t is produced on a large scale and is primarily used in the production of polymers but also sees use in food processing as the E-number E1520. The compound is sometimes called α-propylene glycol to distinguish it from the isomer propane-1,3-diol (β-propylene glycol).

Why Is Antifreeze So Delicious? For obvious reasons, there's been quite a bit of agitation for safer, less scrumptious antifreeze. One solution has been the development of antifreezes, including one called SIERRA, that replace ethylene glycol with propylene glycol, a liquid that's nontoxic enough to be used as a sweetener in children's cough syrup. But propylene glycol costs significantly more than ethylene glycol. Lawmakers have also taken up the cause. Oregon and California both require that antifreeze manufacturers add a bittering agent to their products, in order to make them unpalatable to pets and children (and, one would presume, potential murder victims).

Propylene glycol, on the other hand, is used to reduce the toxicity of antifreeze. This is a story about the toxicity of the right-wing echo chamber. The toxicity when given subcutaneously is about 15 to 20 per cent greater than when given by mouth. Intramuscularly the toxicity is 30 percent greater than subcutaneously.

Toxic Substances Portal - Propylene Glycol Propylene glycol is a synthetic liquid substance that absorbs water. Propylene glycol is also used to make polyester compounds, and as a base for deicing solutions. Propylene glycol is used by the chemical, food, and pharmaceutical industries as an antifreeze when leakage might lead to contact with food. The Food and Drug Administration (FDA) has classified propylene glycol as an additive that is generally recognized as safe for use in food.
