Magnesium chloride

The primary purpose of magnesium chloride is the chemical industry that uses this substance in chemical syntheses, but also the pharmaceutical and pharmacological industries. Numerous creams, conditioners and balms are produced on the basis of magnesium chloride.

In autumn and winter, it is an alternative to sodium chloride and calcium chloride for road maintenance. Absorbing moisture, it generates a relatively large amount of heat, so it actively defrosts icy surfaces. Used on the road in an amount of almost one to ten in relation to traditional road salt. The recommended amount of sodium chloride - traditional road salt - is about 18.3 kg per 100 m2, thus we need about 0.183 kg to de-ice 1 m2. Meanwhile, magnesium chloride is dosed in amounts of approx. 2.5 kg per 100 m2, i.e. approx. 0.025 kg per m2. It works even down to minus fifty degrees Celsius. In reality, however, its use already at minus twenty degrees Celsius requires time to initiate the reaction. Heat is released when water is absorbed. When the humidity is lowered by the temperature, it warms up very slowly right after application, when there is enough heat, moisture will appear, which will fuel the reaction. Reaching the critical point, when the reaction begins to bring real effects at temperatures below minus twenty degrees, may take up to several hours. Magnesium chloride does not degrade the natural environment, is not harmful to humans and animals. It does not corrode vehicles and does not settle on shoes. It does not affect the road surface.
