Any substance which is a solute that lowers the freezing point of a solvent. Water(Hydrogen oxide) is the usual solvent. The solute is usually sodium chloride, calcium chloride, ethylene glycol(toxic), propylene glycol(non-toxic, safe), 1,2-Butyleneglycol(nontoxic) glycerol(nontoxic), ethanol, and a tick protein called IAFGP. Ticks have a protein called IAFGP that is triggered during winter months, which protects them from the cold. The freezing point of the solution gets lowered. Freezing point depression is a colligative property.
I put propylene glycol antifreeze in my car and it resisted freezing in the winter. The dog accidentally drank some propylene glycol but turned out fine. If it would have been ethylene glycol, the dog would have died.

Antifreeze is that greenish yellow liquid your dad puts in the car. It's ethylene glycol. It keeps the car's cooling engine from freezing. It's done in cold places and it's a tradition that goes from generation to generation. Don't drink it though, or you'll die. It's sweet tasting, but deadly toxic if you drink it.
You: Dad? What's that yucky green stuff you're putting in the car?
Dad: That's antifreeze! Someday you'll follow in my footsteps and winter-proof your car engine.

An alcoholic drink that one may make by mixing Golden Grain and green Hawaiian Punch.

Also known as Hunch Punch if Golden Grain is mixed with red Hawaiian Punch.
Let's mix up some antifreeze in a gas jug so if a cop pulls us over, they won't suspect shit.

2. heroin
This antifreeze is so strong it could be used to disinfect wounds.
