Glycerin, also known as glycerol (IUPAC name: propane-1,2,3-triol) is a non-toxic sugar alcohol used as an antifreeze in slushies or other frozen drinks.
It is a viscous alcohol with a viscosity somewhere between maple syrup and golden syrup.
It used to be used in car antifreeze before ethylene glycol was discovered, but was phased out because ethylene glycol had far superior antifreeze, antiboil, and heat-transfer properties compared to glycerin.
While glycerin is non-toxic to adolescents and adults, it can be toxic to young children due to their bodies inability to deal with the substance, potentially resulting in hypoglycemia.

This hand sanitiser contains glycerin as a stabilizer to stop the ethanol from evaporating as quickly when on the hands.

Get the the glyph mug.Ethylene glycols scientific (IUPAC) name is "ethane-1,2-diol".
It is an excellent choice for use in things such as car antifreeze, due to its great heat transfer properties and its terrific antifreeze up and antiboil over chemistry when combined with water.
It has a sweet taste and a pleasant flavour profile which is why bittering agents are added to antifreeze/coolant formulations, to prevent accidental ingestion.
Despite its sweet taste, ethylene glycol is a very poisonous substance, due to its metabolic breakdown in the body;
Ethylene glycol itself is relatively non-toxic, but when it's ingested by humans or animals, the liver will try to metabolise the antifreeze the same way as metabolises regular food-grade alcohol, but it will accidentally convert the glycol into poisonous and harmful organic acids, which can poison the body and be lethal.

Example 1: This high-performance coolant contains ethylene glycol, which provides great antifreeze and antiboil protection in the engine. Bittering agents have also been added to the formula for safety of your children and pets.

It has a sweetish taste and flavour, and is safe to consume in smaller amounts.
It is a common ingredient in food & drinks, cosmetics, hand soaps, liquid medicines, and more.
It has a cousin called propanediol, which is also known as propane-1,3-diol, and it is more naturally abundant than propane-1,2-diol.
Both propylene glycol and propanediol are technically edible, unlike the glycols called ethylene/diethylene glycol.

This icecream uses an edible antifreeze to make its palate smoother and creamier, it's called propylene glycol.
This engine coolant is formulated with a non-toxic glycol called propylene glycol, unlike most conventional coolants which are ethylene glycol based.
