According to the law of the European Union, cosmetics producers have to use the INCI system (International Nomenclature of Cosmetic Ingredients). The INCI order assumes that the names of the ingredients are listed, starting with the substance used in the highest amount, and ending with the substance of the lowest concentration. The name Magnesium Chloride comes from this system and indicates magnesium chloride (MgCl2), one of the commonly available substances.

General characteristics

Magnesium chloride is a mineral salt obtained in a hydrated form, mainly from sea water, brine and carnallite (a mineral of chemical sedimentary rocks). To precipitate magnesium hydroxide, seawater is subjected to a reaction with alkalis and the resulting hydroxide is then converted into magnesium chloride using hydrochloric acid. It is separated from the aqueous solutions as hexahydrate (MgCl2*6H2O). The anhydrous salt is obtained by heating. This inorganic compound is water-soluble and highly hygroscopic. For living organisms, it is a well-absorbed form of magnesium.  The CAS number of the compound is 7791-18-6. This organization based in USA gives a unique numerical designation to a given compound. Magnesium Chloride comes in the form of white shiny crystals, or white or grey granules or flakes. Most often it is a compound of natural origin.

Applications in cosmetic products

In cosmetics, magnesium chloride acts as a deodorant that prevents unpleasant odours. The aroma of the compound itself affects the aromatic qualities of the finished product. In addition, it acts as an active, antibacterial, antiseptic and bactericidal substance, while maintaining a low pH, thus contributing to wound healing, alleviation of inflammatory conditions and preventing the microbial colonization of the product. These properties are used when preparing baths containing magnesium chloride in the fight against mycosis. In addition, it is a compound used to thicken cosmetic formulations and to increase their viscosity. Also, magnesium chloride has unique properties of penetrating into the bloodstream through the skin. This effect is used in the production of magnesium supplements in the form of solutions, mists and body oils. When absorbed through the skin, magnesium strengthens bones and supports the fight against osteoporosis. Currently, the most common preparation on the cosmetic market containing this compound is bath salt. The great advantage of using this type of treatment at home is the simultaneous supplementation of magnesium deficiencies and acceleration of the regeneration of the body.

Other uses

In addition to the use of magnesium chloride in cosmetics, the most popular application is the use of this substance in the pharmaceutical market. Many factors can contribute to magnesium deficiency in the body, so it is worth to buy supplements available in pharmacies, despite the fact of its unpleasant taste. Additionally, magnesium chloride is often used as a fertilizer in horticulture. Both the ionic form of the chlorine atom and the magnesium atom are micronutrients for plants. Moreover, magnesium chloride, available in technical form, is used in transport and road traffic because it eliminates moisture very quickly. For this reason, it is used as a protective and sanitary chemical compound.

Safety of cosmetics containing Magnesium Chloride

Magnesium Chloride is a safe substance designed for use in cosmetic preparations. There are no specific, more widely described limitations on the use of this compound as an ingredient in cosmetic formulations. When added in high concentrations to supplements in the form of solutions, Magnesium Chloride is not recommended for people with thyroid conditions. No negative impact of Magnesium Chloride on the environment was observed.
