Cosmetic Grade Calcium Carbonate-CAS 471-34-1
Cosmetic Grade Calcium Carbonate Powder is a high-purity low-hardness inorganic mineral powder specially refined for cosmetic formulas. With ultra-fine particle size, high whiteness and soft texture, it is a versatile formula auxiliary material different from traditional clay and slippery mineral powders.
It does not have strong oil adsorption or pearlescent shimmer performance, but focuses on optimizing cosmetic texture and structural stability. It can significantly increase powder bulkiness and moldability, improve powder ductility and skin-fitting comfort, and create natural soft matte makeup without abrasiveness.
Its stable chemical inertness ensures good compatibility with all cosmetic systems, effectively improving formula flatness and color uniformity, avoiding uneven coloring and rough makeup texture. As a mild and high-cost-effective filler, it balances product formula cost and use experience, and is widely used in various daily cosmetic matte texture modification and powder formula optimization.
Key Benefits
• Ultra-Low Hardness & Super Soft Skin Feel: Low-hardness soft powder structure, no granular grit and no skin abrasion, effectively eliminate makeup rough texture, create fluffy and delicate matte skin feel.
• High Purity & Safe Mildness: High-purity ore purification process, ultra-low heavy metal, no harmful residues, non-irritating and non-sensitizing, safe for long-term facial skin contact.
• High Whiteness & True Color Rendering: Pure white base without color cast, does not cover or distort pigment color, ensures accurate and uniform color development, clean and natural makeup effect.
• Excellent Powder Molding Performance: Improve powder bulkiness and compactness, enhance pressed powder crack resistance and compression stability, effectively prevent powder peeling and loose powder flying.
• Moderate Oil Control & Non-Drying: Balanced oil absorption capacity, moderately adsorb skin surface grease to reduce greasy shine, without stripping skin moisture, avoiding dry and tight makeup.
• High Compatibility & Stable Batch Quality: Chemically inert and acid-base resistant, compatible with full-system cosmetic formulas, stable performance without deterioration, suitable for large-scale mass production.
Applications

Frequently Asked Questions (FAQ)
• Q1: What is the MOQ of Cosmetic Grade Calcium Carbonate Powder?
A1: The standard MOQ is 25KG, and sample orders are supported for formula testing and efficacy trial production.
• Q2: What compliance documents can be provided for cosmetic filing?
A2: Complete COA, MSDS, heavy metal test report and microbial test report are available, fully supporting domestic cosmetic filing and international export customs clearance.
• Q3: What is the recommended dosage in cosmetic formulas?
A3: Loose & pressed powder: 15%–40%; Eyeshadow & blush: 10%–30%; Matte foundation & concealer: 5%–15%; Skincare cream & lotion: 2%–8%; Mild cleansing products: 3%–10%, adjustable according to formula texture and cost optimization needs.
• Q4: What is the difference between calcium carbonate, talc, kaolin and bentonite?
A4: Calcium carbonate focuses on soft skin feel, high bulkiness and cost performance, low hardness and non-drying, suitable for universal matte filling; Talc focuses on ultra-smooth slip; Kaolin focuses on strong oil adsorption and deep cleansing; Bentonite focuses on thickening and suspension stabilization. Four powders can be compounded freely to balance skin feel, oil control, stability and cost.
• Q5: Will calcium carbonate cause dry skin or irritation?
A5: No. Cosmetic grade calcium carbonate has low hardness and moderate oil absorption, no strong degreasing ability. It will not strip skin natural moisture, with mild and non-irritating properties, suitable for sensitive skin formula production.
• Q6: What are the formula matching notes?
A6: Fully stir and disperse evenly during batching; reasonably compound with talc and kaolin to adjust matte and oil-control effect; control dosage to maintain powder fluffiness; store finished products in moisture-proof sealing to avoid agglomeration.
• Q7: Do you support stable mass supply and customized processing?
A7: Standardized purification production line ensures stable batch whiteness, particle size and oil absorption value. Sufficient inventory all year round supports long-term bulk orders and customized particle size processing for exclusive formulas.
