Cosmetic Grade Magnesium Carbonate-CAS 546-93-0
Cosmetic Grade Magnesium Carbonate Powder is a high-purity ultra-light inorganic mineral powder specially synthesized for high-end cosmetic matte and oil-control formulas. With ultra-high bulkiness and superior oil absorption performance, it is a professional functional filler different from all conventional cosmetic powders.
It does not rely on strong friction or deep cleansing, but uses unique porous fluffy structure to achieve efficient physical oil absorption and powder modification.
It can significantly improve the fluffiness and smoothness of powder cosmetics, solve the problem of hard pressing and agglomeration of long-term stored powder, and create a light, thin and soft matte makeup effect. Its stable weak alkalinity can effectively buffer formula pH changes, improve the compatibility of various raw materials, and enhance the overall stability of cosmetic systems.
With excellent color rendering and non-color-shifting characteristics, it maximizes the reduction of pigment color. It is the preferred core material for high-grade long-wear matte makeup and high oil-control cosmetic formulas.
Key Benefits

Frequently Asked Questions (FAQ)
• Q1: What is the MOQ of Cosmetic Grade Magnesium Carbonate Powder?
A1: The standard MOQ is 25KG, and sample orders are supported for formula testing and efficacy trial production.
• Q2: Is the product compliant for cosmetic filing and export?
A2: 100% asbestos-free, ultra-low heavy metal, fully compliant with cosmetic safety standards. Complete COA, MSDS, heavy metal and microbial test reports can be provided to support domestic filing and international export customs clearance.
• Q3: What is the recommended dosage in cosmetic formulas?
A3: Oil-control loose/pressed powder: 8%–25%; Eyeshadow & blush: 5%–18%; Matte foundation powder: 6%–20%; Anti-caking powder system: 3%–12%; High-fluff makeup: 10%–30%, adjustable according to oil-control and fluffy texture requirements.
• Q4: What is the difference between magnesium carbonate and calcium carbonate?
A4: Magnesium carbonate focuses on ultra-high oil absorption, super fluffiness and anti-caking, suitable for high oil-control and long-wear matte formulas; Calcium carbonate focuses on soft skin feel, filling and cost performance, suitable for universal mild matte formulas. The two are perfectly compoundable to balance fluffiness, oil control and skin feel.
• Q5: Will magnesium carbonate cause dryness or irritation?
A5: No. It adopts mild physical oil absorption without strong degreasing effect. It only adsorbs excess grease on the skin surface, retains skin natural moisture, with mild weak alkalinity and non-irritating properties, suitable for daily and sensitive skin formulas.
• Q6: What are the formula matching notes?
A6: Fully disperse evenly during batching; compound with talc and kaolin to balance slip and cleaning power; control dosage to avoid excessive matte texture; store finished products in moisture-proof sealing to maintain fluffiness and anti-caking activity.
• Q7: Do you support stable mass supply and customized processing?
A7: Standardized synthetic production line ensures stable batch whiteness, oil absorption and bulkiness. Sufficient inventory all year round supports long-term bulk orders and customized particle size processing for exclusive formulas.
