Cosmetic Grade Diatomite Powder -CAS 68855-54-9
Cosmetic Grade Diatomite is a natural biogenic silicate mineral powder formed by ancient diatom remains after geological deposition and purification. It features unique three-dimensional microporous structure with ultra-high porosity, strong physical adsorption and excellent oil absorption capacity.
Different from chemical oil-control ingredients that are easy to dry and irritate the skin, diatomite relies on pure physical adsorption to remove skin grease and dirt, with mild and non-damaging cleaning effect. Its ultra-fine smooth particle shape provides soft physical exfoliation, effectively improving skin roughness and dullness.
As a classic cosmetic functional filler, it can optimize the compactness, slip property and matte texture of powder makeup, enhance makeup air permeability and lasting power, and avoid greasy and cakey makeup. With stable chemical inertia, safety and environmental protection, it is an essential natural raw material for clean skincare and matte long-wear makeup.
Key Benefits
• Super Strong Physical Oil Control & Purification: Unique high-density microporous structure efficiently absorbs excess facial oil, pore dirt and residual waste, deeply cleans pores, refreshes oily skin, and improves rough and dull skin texture.
• Mild Exfoliation & Barrier-Safe: Ultra-fine round particles achieve soft physical exfoliation, gently remove dead skin cells without scratching or irritating the skin, brighten complexion while protecting the skin barrier.
• Breathable Matte Makeup Modification: Optimizes powder slip and moldability, creates natural soft matte skin finish, eliminates greasy shine, prevents makeup cakey and floating powder, improves makeup air permeability and comfort.
• Excellent Formula Stability & Anti-Caking: Inert and stable properties, effectively improve powder anti-caking performance, uniform formula dispersion, prevent oil floating and precipitation, enhance finished product storage stability.
• Natural Safe & Wide Compatibility: Pure natural mineral source, physical sterilization and purification, zero irritation and zero sensitization, compliant with global cosmetic standards, compatible with skincare and makeup full-system formulas.
• High Cost-Performance & Mass Production Friendly: Stable batch fineness and purity, uniform powder performance, easy to disperse and process, perfectly suitable for large-scale standardized production of natural cosmetic products.
Applications
• Deep Cleansing Skincare: Widely used in cleansing masks, clay masks, exfoliating scrubs and pore purifying skincare products, relying on physical adsorption to achieve deep pore cleaning, improve skin roughness and dullness.

Frequently Asked Questions (FAQ)
• Q1: What is the MOQ of Cosmetic Grade Diatomite?
A1: The standard MOQ is 25KG, and sample orders are supported for formula testing and trial production. Custom fineness (800/1250/2000 mesh) is available.
• Q2: Is cosmetic diatomite safe for skin?
A2: Yes. Our diatomite adopts pure physical purification and high-temperature sterilization process, free of asbestos, heavy metals and chemical residues. It is mild and non-irritating, non-sensitizing, compliant with global cosmetic safety standards, safe for long-term skin contact and suitable for sensitive skin formulas.
• Q3: What is the recommended dosage in cosmetic formulas?
A3: Cleansing mask & scrub: 3.0%–10.0%; Oil-control skincare lotion/cream: 1.0%–5.0%; Powder makeup (loose powder/pressed powder): 5.0%–15.0%; Deodorant products: 2.0%–8.0%, adjustable according to target oil control and texture requirements.
• Q4: What is the difference between diatomite and common talc powder?
A4: Talc powder focuses on smooth filling with weak adsorption; diatomite has ultra-high porosity and strong physical oil control and dirt adsorption capacity, with natural exfoliating and pore purifying effects. It is more suitable for oil-control cleaning and matte long-wear formulas, safer and more functional than traditional filler powder.
• Q5: What formula systems is it compatible with?
A5: It has excellent inert compatibility with water phase, oil phase and emulsion systems, widely used in solid powder, paste and emulsion cosmetic products. Uniform dispersion without agglomeration, no adverse reaction with conventional cosmetic raw materials.
• Q6: What are the formula matching notes?
A6: Ultra-fine powder is easy to absorb moisture, seal and store raw materials; fully disperse and stir during feeding to avoid local agglomeration; control reasonable dosage to prevent excessive dosage from causing rough skin feel; match with moisturizing ingredients to balance dryness.
• Q7: Do you support customized processing and stable supply?
A7: Support customized mesh fineness and purity grades. Strict impurity removal and sterilization treatment ensure stable adsorption performance and powder quality. Sufficient inventory all year round supports long-term bulk orders and professional formula technical guidance.
