Messi Biology states that cosmetic-grade Magnesium Carbonate (MgCO₃) is a natural and mild inorganic mineral powder. Thanks to its unique microporous structure and stable physicochemical properties, it has become a core raw material in color cosmetics, base makeup, skincare, deodorants, and other fields. Known for its safety and efficiency, it helps upgrade formulas and enhance user experience, serving as a low-profile yet crucial “powerhouse” ingredient in beauty products.
In color cosmetics and setting products, Magnesium Carbonate is the primary component responsible for oil control and long-wear performance, with a typical addition level of 10%–25%. In loose powders and setting powders, its microporous structure strongly adsorbs excess skin oil to achieve 12-hour long-lasting oil control, quickly smoothing out shine for a premium matte finish. Simultaneously, it enhances the adhesion between the powder and the skin, preventing makeup from fading or creasing, and keeping the look refined all day. When added to eyeshadows and blushes, it significantly improves the spreadability of the powder, ensuring smooth application without clumping, fundamentally reducing “fallout” issues, and stabilizing color presentation for a more even and long-lasting finish.
Base makeup is another vital application scenario for Magnesium Carbonate, where addition levels are typically controlled between 3%–5%. Adding Magnesium Carbonate to liquid foundations and BB creams provides gentle oil control and conceals shine without compromising the product’s transparency or skin feel, avoiding a heavy or “mask-like” appearance. Furthermore, it stabilizes the distribution of powders, preventing formula separation or sedimentation. This results in a finer texture and better adherence, making it ideal for the daily base makeup needs of oily and combination skin.
In skincare and cleansing products, the addition level of Magnesium Carbonate ranges from 5%–15%, making it an ideal partner for cleansing clay masks. Its powerful adsorption capacity allows it to reach deep into pores to remove blackheads, excess sebum, and dead skin cells, gently clearing impurities. Because its properties are mild and non-irritating, it does not damage the skin barrier; it retains skin moisture during the cleaning process, leaving the skin refreshed rather than tight, which suits the deep-cleansing needs of various skin types.
In body care and antiperspirant products, even an addition level of just 1%–5% allows Magnesium Carbonate to play a critical role. It quickly adsorbs sweat and odor molecules on the skin surface, assisting in body odor suppression and keeping the skin dry. Additionally, it can be formulated with other antiperspirant ingredients to reduce product irritation and enhance gentleness, avoiding the dryness and discomfort often associated with traditional antiperspirants to provide a comfortable, long-lasting dry experience.
Cosmetic-grade Magnesium Carbonate functions primarily through physical action, contains no harmful chemical additives, and possesses excellent biocompatibility, fully meeting the safety standards of beauty products. From oil control and setting to base makeup adherence, and from deep cleansing to skin-dryness maintenance, it adapts to diverse category needs through its multi-faceted efficacy. By balancing performance and mildness, it has become an indispensable high-quality mineral raw material in cosmetic formulations, providing reliable support for high-end beauty products.
