Magnesium chloride is a versatile ingredient that finds its way into various cosmetic products. Sourced primarily from seawater and brine, this compound is composed of magnesium and chlorine ions. Its chemical formula is MgCl₂, and it appears as a white or colorless crystalline solid. Historically, magnesium chloride has been used for a range of applications, from de-icing roads to serving as a dietary supplement. Its journey into the world of cosmetics is relatively recent, driven by its beneficial properties for skin and hair care.
The production of magnesium chloride typically involves the extraction of magnesium from seawater or mineral deposits. This is followed by a purification process to remove impurities, resulting in a high-quality, cosmetic-grade ingredient. The compound is then either dissolved in water or incorporated into various formulations, depending on its intended use. Its ability to control viscosity and enhance the texture of cosmetic products makes it a valuable addition to many skincare and haircare lines.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Magnesium Chloride:
Magnesium Chloride is used as a flavouring agent in cosmetic products. While this might sound a bit unusual, certain cosmetics, especially those that are applied to the lips or around the mouth, can benefit from a pleasant taste. This ensures that the product is not only effective but also enjoyable to use. Imagine applying a lip balm that tastes good – that’s where Magnesium Chloride comes into play.
Another significant role of Magnesium Chloride in cosmetics is its ability to control viscosity. Viscosity refers to the thickness or thinness of a product. By adjusting the viscosity, Magnesium Chloride helps in achieving the desired consistency of creams, lotions, and gels. This ensures that the product spreads evenly and feels just right on your skin. No one likes a cream that’s too runny or too thick, and Magnesium Chloride helps strike that perfect balance.
Note: The listed benefits above are exclusively based on the officially recognized and defined functions of the ingredient, as documented by the International Nomenclature of Cosmetic Ingredients (INCI).
Magnesium chloride is generally considered safe for topical use in cosmetics. However, as with any ingredient, there are potential side effects and considerations to keep in mind.
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of magnesium chloride during pregnancy are lacking. It is advisable for pregnant or breastfeeding women to consult a healthcare professional for further advice before using products containing this ingredient.
Adverse reactions to magnesium chloride are relatively uncommon, but they can occur. It is recommended to perform a patch test before widespread usage to ensure there is no adverse reaction.
Magnesium chloride has a comedogenic rating of 0, meaning it is considered non-comedogenic. This makes it suitable for individuals who are prone to acne, blemishes, or breakouts, as it is unlikely to clog pores.
