Glycol solutions

Glycol solutions are mixtures of water and organic compounds known as glycols. Glycols are hydrocarbons that have included hydroxyl groups (-OH) that allow the formation of aqueous solutions with high density and the ability to lower the freezing point of water.

The two main types of glycol solutions used in various applications are ethylene glycol and propylene glycol:

Ethylene glycol (C2H6O2):

It is the most common type of glycol solution.
It has the ability to lower the freezing point of water, which makes it ideal for use in cooling and heating systems as a coolant.
Ethylene glycol can be toxic to humans and animals and should be handled with care. Safety guidelines must be followed when using it.
Propylene glycol (C3H8O2):

It is less toxic than ethylene glycol and is often used in cases where it is necessary to ensure lower toxicity.
Like ethylene glycol, it has the ability to lower the freezing point of water, so it is also used as a cooling agent.
Propylene glycol is also used in the food industry as a food additive.
Glycol solutions are mainly used in industries where it is necessary to regulate temperature, prevent freezing and corrosion, for example in cooling and heating systems, in the food industry, in the automotive industry and other applications where temperature control and corrosion protection are important.
