Evonik’s Multiple Silica Products: Properties, Applications, Certifications & Cost Advantages

Evonik has launched a series of high-performance silica products, covering food, pharmaceuticals, cosmetics, rubber, coatings, and other fields. These products feature excellent adaptability, global compliance, and cost advantages, providing professional solutions for industrial upgrading. Below is the key information of core products:  

1. Sipernat 22

•Core Performance: Hydrophobic precipitated silica with high porosity, excellent adsorption (converts liquids to "dry powder"), weak alkalinity (pH 10.5, neutralizes acidic systems), and dual functions of anti-caking and rheology adjustment.  
•Key Applications: Food (anti-caking for spices, ready-to-eat foods; compatible with molecular gastronomy), pharmaceuticals (excipient for tablets/capsules, converts liquid drugs to solid powder), cosmetics (thickener/polisher for toothpaste, fragrance stabilizer for lipsticks/antiperspirants), and industry (carrier for defoamers/rubber additives, softener for rubber).  
•Certifications: EU E551, US FDA (food contact), Kosher; low heavy metal content.  
•Advantages: No high-temperature pretreatment, easy dispersion, biodegradable (no microplastics), suitable for 3D printed food and high-end pet food.  

2. Sipernat 22S/F

•Core Positioning: Food-grade silica for anti-caking & flow aid, with SiO₂ ≥98% and fine, high-flow powder.  
•Key Applications: Food (0.2%-2% addition for non-dairy creamers/condiments to prevent caking), agriculture (carrier for wettable powder (WP)/water-dispersible granule (WG), no fine grinding needed), paper (additive for mechanical graphic paper to reduce ink bleeding).  
•Certifications: EU E551, Kosher, Halal.  
•Advantages: Compatible with low-to-medium shear mixers, stable under regular storage (loss on drying ≤7%), low addition amount, cost-effective; safe for infant food.  

3. Sipernat 50S

•Core Feature: High purity (98.9%-99.9% silica, ultra-low impurities) for high-end scenarios.  
•Key Applications: Food (anti-caking for milk powder/condiments, no impact on solubility), rubber (reinforcing filler for silicone rubber/HTV to improve hardness), plastics (enhances aging/heat resistance of polyethylene), coatings/inks (improves wear resistance and anti-bleeding).  
•Certifications: National standard, EU standard, US FDA (food contact).  
•Advantages: Easy dispersion in low shear, non-hazardous (simple storage), multi-scenario adaptation (food + industry), cost-saving for bulk procurement.  

4. ZEOFREE 110 SD

•Core Positioning: Hydrophilic food-grade silica (special SD process) for anti-caking & flow aid.  
•Key Applications: Instant drinks (0.1%-1% addition for instant coffee/solid drinks to improve dispersion), condiments (prevents caking of chili/curry powder, no flavor impact), functional food (carrier for probiotics/vitamins).  
•Certifications: EU E551, US FDA, Kosher, Halal.  
•Advantages: Suitable for spray drying/late mixing, stable under regular storage, low addition amount (0.1%-2%), safe for infant/elderly nutrition powder.  

5. SIPERNAT 50

•Classic Position: Basic hydrophilic precipitated silica (SiO₂ ≥98%) for entry-level needs.  
•Key Applications: Food (0.2%-1% addition for salt/sugar anti-caking), industry (flow aid for laundry detergent, matting agent for low-end coatings), feed (carrier for liquid vitamins).  
•Certifications: EU E551, China GB standard.  
•Advantages: Compatible with all mixers (small workshops to large factories), stable (loss on drying ≤8%), low price, suitable for DIY (handmade soap, homemade powder).  

6. SIPERNAT 680

•Parameter Highlights: Large particle size (d50: 40-60μm), high oil absorption (DOA: 235-265ml/100g), specific surface area: 155-195m²/g.  
•Key Applications: Food (anti-caking for coarse particles like salt/sugar, carrier for nut powder oil), feed (1%-3% addition for premix anti-caking), coatings (matting agent for decorative coatings), inks (improves thixotropy for letterpress printing).  
•Certifications: EU E551, US FDA, FAMI-QS (feed grade).  
•Advantages: Resistant to high-shear mixing, low hygroscopicity, cost-effective (low addition amount).  

7. SIPERNAT 28

•Core Performance: Balanced hydrophilic precipitated silica (SiO₂ ≥98%) for general scenarios.  
•Key Applications: Food (0.3%-2% addition for non-dairy creamer), cosmetics (texture regulator for talcum powder/conditioner, suitable for sensitive skin), pharmaceuticals (flow aid for capsules), industry (lightweight filler for plastics).  
•Certifications: EU E551, US FDA.  
•Advantages: Easy dispersion, stable (loss on drying ≤7%), mid-range price (cost-effective for SMEs), suitable for pet dry food.  

8. ZEOFREE 5162

•Core Feature: Hydrophilic ground precipitated silica (d50:17-22μm) for anti-caking/flow aid/carrier.  
•Key Applications: Food (spice/nutrition premix anti-caking), feed (carrier for liquid vitamins), agriculture (carrier for WP pesticides), home care (flow aid for laundry detergent).  
•Certifications: EU E551, US FDA, Kosher, Halal, FAMI-QS.  
•Advantages: Compatible with grinding processes, low storage loss, multi-functional (no need for multiple additives).  

9. 325Mesh E551

•Core Marker: Food-grade silica (325-mesh sieve, ~44μm) compliant with EU E551.  
•Key Applications: Food (0.1%-2% addition for flour/starch/condiments), instant drinks (improves dispersion), industry (matting agent for low-end coatings).  
•Certifications: EU E551, US FDA.  
•Advantages: Standard particle size (compatible with most equipment), low cost, small packaging available (for small workshops).
