Representative Cases
•Passed Nestlé on-site audit (Oct 2025) and became a certified supplier approved for pet food and food wet/dry mixing scenarios.
•Decade-long COFCO partnership guarantees stable tomato powder flowability.
•Yihai Kerry refining: adsorbent with customized pore structure and high specific surface area removes phospholipids and trace metals, improving transmittance and reducing clay and crude-oil loss.
•HaiDiLao beef tallow: optimized particle size raises filtration efficiency by 40%, enabling anhydrous degumming and less wastewater.
•Zoilsil58GS for Snow Beer and Budweiser selectively adsorbs sensitizing proteins and polyphenols as a filter aid, preserving foam and malt flavor.
Applications
Anti-caking silica prevents powder caking and improves flowability. Adsorbent silica removes impurities from liquid systems. Pharmaceutical excipient supports drug loading and gliding. Toothpaste-grade balances cleaning and stability. Cosmetic-grade adjusts skin feel. Pet-feed preserves nutrition and palatability. Antiblock masterbatch serves PET, BOPP and CPP films.

Success Stories & Case Studies
Food groups, edible-oil companies, beer companies, pet-food companies and international food brands.
Works as both abrasive and thickener. Moderate RDA gently removes plaque, food debris and extrinsic stains without damaging enamel. It stabilizes paste matrix to prevent water separation, stratification and sagging, ensuring smooth extrusion, good shape retention and creamy fine foam. Low-RDA variant minimizes brushing irritation for sensitive teeth. Custom grades achieve high-efficiency whitening or crystal transparent paste. Chemically inert, compatible with fluoride, desensitizers, herbal extracts and probiotic ingredients. Consistent batch quality and excellent powder dispersibility reduce agglomeration and production rework, lifting finished product yield.
1. Dual function: works as both abrasive and thickener.
2. Adjustable RDA: meets daily, sensitive and whitening toothpaste demands.
3. Mild cleaning: removes plaque and stains without hurting enamel.
4. Ultra-low iron, no black spots; pure white powder avoids paste discoloration.
5. Good thixotropy: prevents water separation, layering and paste sagging.
6. Excellent dispersibility, easy mixing, less agglomeration, higher production yield.
7. Wide compatibility, fits transparent & opaque toothpaste, fluoride/herbal formulas.
8. Stable batch quality, customizable oil absorption, complete compliance documents.
