Censil is a professional manufacturer of sodium aluminosilicate (also known as sodium aluminum silicate or SAHS), produced by Longyan Shenghe Chemical Co., Ltd. in Fujian, China. Censil synthetic amorphous sodium aluminosilicate is a white, odorless powder with a porous aluminosilicate framework — providing excellent adsorption capacity, superior anti-caking performance, and selective mycotoxin binding for feed, food, and industrial applications.
As a certified sodium aluminosilicate manufacturer in China, Censil holds FAMI-QS certification (Certificate No. CNBJ380053-CN, audited by Bureau Veritas, valid through March 2027), ISO 22000, HACCP, and HALAL certification (SSPY-201318-32223-R3, valid through June 2027). Censil sodium aluminosilicate is FDA GRAS-compliant (21 CFR 182.2727) and EU EFSA-approved, serving feed mills, food processors, and industrial customers across 40+ countries as a reliable alternative to international sodium aluminosilicate brands.
Censil sodium aluminosilicate for feed is a multi-functional feed additive that serves three critical roles: anti-caking agent for premixes and compound feed, mycotoxin binder that selectively adsorbs aflatoxins and other toxins, and pellet binder that improves pellet durability and reduces feed waste.
| Feed Application | Function | Recommended Dosage | Key Benefit |
|---|---|---|---|
| Mineral Premixes | Anti-caking agent | 0.5-2.0% | Prevents caking from hygroscopic minerals, ensures uniform flow |
| Compound Feed (Poultry/Swine) | Anti-caking, mycotoxin adsorption | 0.5-2.0% | Improves flow in automated feeders, reduces aflatoxin toxicity |
| Pellet Feed | Pellet binder | 1.0-2.0% | Increases pellet durability index (PDI), reduces fines |
| Milk Replacer | Anti-caking, carrier | 0.3-1.0% | Maintains free-flow in high-fat formulations |
| Aquaculture Feed | Mycotoxin binder, pellet binder | 0.5-2.0% | Water-stable pellets, toxin reduction in aquatic environment |
| Pet Food | Anti-caking, carrier for additives | 0.5-1.5% | Uniform kibble quality, additive dispersion |
The aluminosilicate framework of Censil sodium aluminosilicate provides ion-exchange capacity and selective adsorption properties. The layered crystalline structure and negative surface charge selectively bind positively charged mycotoxins — particularly aflatoxin B1 — in the animal's gastrointestinal tract. The bound toxins are excreted without being absorbed, preventing:
Adding 0.5-2.0% of Censil sodium aluminosilicate for feed significantly reduces mycotoxin bioavailability, protecting animal health and productivity — especially in regions with high grain mold contamination.
Censil food grade sodium aluminosilicate is approved under FDA 21 CFR 182.2727 as GRAS (Generally Recognized as Safe) for use as an anti-caking agent in food at levels not exceeding 2%. It is also listed as INS 554 by JECFA/Codex Alimentarius. Censil food grade sodium aluminosilicate prevents caking and improves flowability in:

Selection Guide: Choose sodium aluminosilicate when you need mycotoxin binding, ion-exchange capability, or cost-effective anti-caking for salt and seasonings. Choose precipitated silica when you need high liquid absorption (carrier applications), premium anti-caking for high-oil feed premixes, or maximum surface area for rheology control. Many formulators use both — sodium aluminosilicate for primary anti-caking and toxin binding, combined with silica for enhanced moisture control and flow improvement.

Sodium aluminosilicate (also known as sodium aluminum silicate or SAHS, INS 554, E-554) is a synthetic amorphous powder with a porous aluminosilicate framework. It is widely used as an anti-caking agent in feed and food, a mycotoxin binder that adsorbs aflatoxins and other toxins in animal feed, and a pellet binder that improves feed durability. In food, it prevents caking in powdered foods, spices, and beverage mixes (FDA GRAS, 21 CFR 182.2727). It also serves as a builder and flow aid in detergents, and as a functional additive in catalysts, pigments, and pharmaceuticals.
Yes. Censil sodium aluminosilicate is approved for use in both animal feed and food applications. It holds FAMI-QS certification (Certificate No. CNBJ380053-CN), ISO 22000, HACCP, and HALAL certification. Under FDA regulations (21 CFR 182.2727), sodium aluminosilicate is Generally Recognized as Safe (GRAS) for use as an anti-caking agent at levels not exceeding 2% in food. The EU EFSA has also evaluated synthetic amorphous sodium aluminosilicate as a safe feed additive. Censil products meet all heavy metal limits: Pb ≤5 mg/kg, As ≤3 mg/kg, Hg ≤1 mg/kg — compliant with JECFA specifications.
Sodium aluminosilicate and silica are both effective anti-caking agents, but they work through different mechanisms. Sodium aluminosilicate has an aluminosilicate framework with ion-exchange capability, making it superior for mycotoxin adsorption and cation binding in feed. Silica has a much higher surface area (160-310 m²/g) and is more effective for moisture-based anti-caking and liquid carrier applications. Sodium aluminosilicate works primarily through ion exchange and selective adsorption of polar molecules, while silica works through surface moisture adsorption. Many formulators use both — sodium aluminosilicate for toxin binding and silica for moisture control.
Sodium aluminosilicate acts as a mycotoxin binder through its aluminosilicate framework's ion-exchange capacity and selective adsorption properties. The layered structure and negative surface charge of sodium aluminosilicate selectively bind positively charged mycotoxins — particularly aflatoxin B1 — in the animal's gastrointestinal tract. The bound mycotoxins are then excreted without being absorbed, preventing hepatotoxicity, immunosuppression, reduced growth performance, and reproductive issues in livestock. Adding 0.5-2.0% of Censil sodium aluminosilicate to contaminated feed significantly reduces mycotoxin bioavailability.
Yes. Censil sodium aluminosilicate can serve as a cost-effective alternative to international sodium aluminosilicate brands for feed and food applications. Censil matches international specifications (SiO₂ 66-76%, Al₂O₃ 9-13%, Na₂O 4-7%, heavy metals compliant with JECFA limits) with FAMI-QS, ISO 22000, HACCP, and HALAL certifications. For applications requiring both anti-caking and mycotoxin binding, sodium aluminosilicate provides dual functionality that pure silica cannot match. Free samples are available for qualification testing.
Censil sodium aluminosilicate features: SiO₂ 66-76% (ignited basis), Al₂O₃ 9-13%, Na₂O 4-7%, pH 6.5-11.5 (5% slurry), loss on drying ≤8%, loss on ignition 5-11% (on anhydrous basis). Heavy metals: Lead ≤5 mg/kg, Arsenic ≤3 mg/kg, Mercury ≤1 mg/kg. Censil holds FAMI-QS (CNBJ380053-CN), ISO 22000 (114FSMS2300022), HACCP, ISO 9001, ISO 14001, and HALAL (SSPY-201318-32223-R3) certifications. The product is FDA GRAS-compliant and EU EFSA-approved for feed and food use.
