People often say they make magnesium oil with magnesium flakes themselves. Of course this is possible, but please be aware of the differences. Here’s an explanation:
Magnesium flakes are made of magnesium oil. Contrary to what many people think the magnesium flakes do not come directly from the ground and they are also not the original magnesium chloride (magnesium salt) that you sometimes see on the edge of salt lakes such as the Dead Sea. Magnesium flakes are made from magnesium oil and this is a comprehensive process.
In short, magnesium flakes which are used for foot baths and baths do not have the same purity as magnesium oil despite the fact that they are made of magnesium oil.
First of all, magnesium chloride (MgCl2) is hygroscopic, which means that it attracts moisture easily. You may have noticed that if you expose them to humid air they begin to melt. This is because during the manufacturing process an evaporation method is used. This is done under a very high temperature. In order to make magnesium flakes, the magnesium oil is heated to about 160 degrees, where the water is evaporated so that a concentration of 47% magnesium chloride is reached. Due to the heating process the substance will decompose into a small amount of MgCl 2 (magnesium) to MgOHCl (magnesium chloride), MgCO3 (magnesium carbonate) and HCl (hydrochloric acid). The resulting compounds are responsible for the turbidity that may occur after the dissolution of the flakes in water. They are not dangerous, but they are byproducts of the necessary steps to make the magnesium flakes.
Because magnesium flakes have a very high magnesium concentration (47%) they are ideal for body or foot baths. The high dilution (less than 5% in a foot bath), in these applications also means that any by-products arising during the production process are diluted so that their presence cannot cause damage.
When you make your own magnesium oil by adding water to the flakes, this high concentration and the possible impurities can harm the skin and we advise against it. If you want to do it, then please dilute it, but then it does not have the effect of magnesium oil.
For direct transdermal applications, we recommend the pure and 100% pure magnesium oil. This comes straight from the source, without additional heat treatment or resulting compounds.
