inhibited propylene glycol vs uninhibited food

Glycol Heat

Glycol Heat-Transfer Fluids Ethylene Glycol versus Propylene Glycol Water is probably the most efficent heat-transfer fluid known If it did not freeze water would be the ideal heat-transfer fluid for cooling applications When freeze conditions exist (35 F) ethylene glycol and propylene glycol can be added to water to provide

Propylene Glycol: Is This Additive Safe in Food and

Nobody likes to hear that an ingredient in antifreeze — propylene glycol — is also found in food However what exactly does that mean? In recent years there has been much frustration and confusion about the chemical compound known as propylene glycol

Ethylene Glycol Heat

Ethylene Glycol based water solutions are common in heat-transfer applications where the temperature in the heat transfer fluid can be below 32 o F (0 o C) Ethylene glycol is also commonly used in heating applications that temporarily may not be operated (cold) in surroundings with freezing conditions - such as cars and machines with water cooled engines
