Messi Biology states that hidden within the silky feel of loose powders, the long-lasting wear of foundation, and the oil-controlling cleansing of face masks is a naturally derived mineral ingredient: cosmetic-grade magnesium carbonate. This white, odorless inorganic powder, with its unique properties such as a porous structure and mild alkalinity, has become a favored “multi-functional player” among formulators, playing an indispensable role in beauty products.
The core application advantage of magnesium carbonate is oil control and long-lasting wear. The microstructure on the surface of its particles acts like countless tiny sponges, capable of physically adsorbing excess sebum secreted by the skin, reducing skin surface oiliness by 30% within 2 hours, an effect superior to traditional talc. In loose powders and setting powders, it keeps makeup matte and fresh, preventing afternoon shininess. In sports antiperspirants, it reduces the crystallization of sweat salts through ion exchange, while also neutralizing acidic metabolites to inhibit bacterial proliferation, achieving a dual effect of dryness and odor removal. What is even more valuable is that it preferentially adsorbs oil over water; it controls oil without disrupting the skin’s moisture-oil balance, making it suitable for all skin types.
Safety and compatibility make magnesium carbonate a preferred choice for green beauty. As an ingredient derived from natural minerals, it boasts excellent biocompatibility, producing only magnesium ions and carbon dioxide upon decomposition, with no risk of residue. Proven mild and non-irritating in skin patch tests, it can be safely used by sensitive skin. EU regulations have not set a maximum concentration limit for it, only requiring compliance with inhalation safety standards, as well as strict heavy metal content requirements (Lead ≤10 mg/kg, Arsenic≤3 mg/kg). Compared to talc, it not only avoids the risk of asbestos contamination but also offers advantages in oil absorption rate and skin feel, and it can synergize with ingredients like zinc oxide and kaolin, broadening formulation possibilities.
Today, the application of magnesium carbonate continues to innovate. The cosmetic-grade magnesium carbonate developed by Hebei Messi Biology Co., Ltd. has won multiple beauty awards by achieving deep oil adsorption and long-lasting wear, thanks to its ultra-high specific surface area. In the future, functional magnesium carbonate loaded with active ingredients and environment-responsive dynamic oil control formulas are expected to bring further breakthroughs to the beauty industry. From daily foundation to functional care, this understated mineral ingredient is using the power of science to protect both makeup quality and skin health.
