“Antifreeze” or glass washer is a special liquid for car glass that is used in the winter. As you know, water freezes already at zero. Therefore, motorists in the cold season use a special liquid that does not freeze at -20 or -30 degrees. It is recommended to pour antifreeze before the first frosts, when the daytime temperature is above zero. If you pour later, the water will freeze in the tank or nozzles, and it will be difficult to defrost.
Any antifreeze contains alcohol. It is needed so that it does not freeze at low temperatures. Detergents also contain water, surfactant, dye, aromatic substances.
Previously, methyl alcohol was used to manufacture glass washers, which is, however, dangerous for health. That is why its use is now prohibited. Also, low-quality and mostly cheap windshield washers can contain diluted glycerin and saline solution, as a result of which greasy spots appear on the windows of the car.
Ethyl alcohol is also used to make antifreeze. Such products do not have a sharp smell and do not contain poisonous substances. Although they are quite expensive in price. The most common substance for winter washer is isopropyl alcohol (СН3СН (ОН) СН3, propanol-2, isopropanol). This substance can be used for the production of antifreeze liquid for glass in cars, because it is not prohibited for use and is inexpensive. Its main disadvantages are a slightly sharp smell.
The use of ethyl and isopropyl alcohol in the manufacture of windshield washer fluid is permitted by sanitary regulations and is safe for humans.
