Cosmetic Grade Bentonite Powder-CAS 1302-78-9
Cosmetic Grade Bentonite Powder is a high-purity natural montmorillonite clay mineral powder with unique layered swelling and thixotropic properties, specially activated and purified for cosmetic formula applications. As a multifunctional cosmetic rheology modifier, it has irreplaceable thickening, suspension and stabilization effects in aqueous and emulsion formulas.
It can form a stable three-dimensional colloidal network after water hydration, effectively solve the problems of powder settling, liquid delamination and poor texture stability of skincare and makeup products.
Different from other matting clay powders, bentonite balances mild oil adsorption and excellent formula modification performance, which can not only purify skin and refine pores, but also optimize product texture and use feeling.
After ultra-fine grinding and high-temperature activation treatment, the powder has uniform particle size, high purity, no asbestos and no harmful impurities, stable chemical inertness and strong formula compatibility. It is the most practical multifunctional clay material for solving cosmetic system instability and optimizing skincare texture.
Key Benefits

Frequently Asked Questions (FAQ)
• Q1: What is the MOQ of Cosmetic Grade Bentonite Powder?
A1: The standard MOQ is 25KG, and sample orders are supported for formula testing and efficacy trial production.
• Q2: Is the product asbestos-free and compliant for cosmetic filing?
A2: 100% asbestos-free, all physical and chemical indicators meet cosmetic-grade standards. Complete COA, MSDS, asbestos test report and heavy metal test reports can be provided to support domestic cosmetic filing and international export customs clearance.
• Q3: What is the recommended dosage in cosmetic formulas?
A3: Cleansing mud mask: 8%–25%; Skincare cream & lotion: 1%–5%; Matte foundation & concealer: 3%–12%; Suspending color cosmetics: 2%–8%; Exfoliating products: 1%–4%, adjustable according to formula thickening and stabilizing requirements.
• Q4: What is the difference between bentonite and kaolin?
A4: Bentonite focuses on thickening, suspension and formula stabilization, with strong water swelling and thixotropic properties, suitable for emulsions and mud systems; Kaolin focuses on strong oil adsorption and deep cleansing, suitable for high-cleaning mask and matte powder formulas. The two can be compounded to balance cleaning power and system stability.
• Q5: Will bentonite affect product skin feel?
A5: Our activated cosmetic grade bentonite has excellent thixotropy. It thickens to shape in static state and becomes smooth and fluid when stirred. It will not cause sticky, heavy or grainy texture, effectively improving product delicate sense and use experience.
• Q6: What are the formula matching notes?
A6: Need sufficient high-speed stirring and hydration dispersion during batching to exert thickening and suspending performance; match with moisturizing ingredients to optimize skin feel; control dosage to avoid excessive viscosity; store finished products in moisture-proof and sealed environment.
• Q7: Do you support stable large-batch supply all year round?
A7: Standardized activation production line ensures stable batch swelling value, particle size and purity. Sufficient inventory all year round supports long-term bulk orders and customized processing for exclusive formula requirements.
