CS-FD150
German premix feed producer
Need
Caking during bulk silo storage; incumbent anti-caking agent needed 2.0% dosage yet still clumped after 6 weeks, causing ~4 hours of dispensing-line downtime per month.
Solution
Censil Silica recommended CS-FD150, a high-porosity precipitated silica (BET 180 m²/g, low tapped density). At 0.8% dosage it out-performed the previous agent at 2.0%, validated over a 90-day trial across three production runs.
Results- Dosage reduced 60% (2.0% → 0.8%)
- Zero caking incidents in 12-month follow-up
- Annual silica cost down 18%
- Dispensing line OEE 92% → 97%
“We switched 18 months ago and haven't had a single silo blockage since. Your technical team came to our plant in Lower Saxony twice during the trial — that level of support is rare.”
— Klaus M., Production Director, Germany
Oil refining · Spain
CS-OE550
Spanish olive oil refinery
Need
Water degumming left residual phospholipids at 18–22 ppm on 200 t/day of crude pomace oil, forcing over-bleaching that raised bleaching-earth use and neutral-oil loss.
Solution
CS-OE550 silica hydrogel (BET 400–600 m²/g, pore volume 1.2 mL/g) dosed at 0.12% w/w into pre-bleaching, adsorbing phospholipids and trace soaps ahead of the bleaching-earth stage.
Results- Residual phosphorus consistently below 5 ppm
- Bleaching-earth consumption down 35%
- Filter cycle extended 4 h → 7 h
- ~EUR 48,000 annual savings
“The bleaching earth savings alone paid for the silica in the first quarter. We've since recommended CS-OE550 to two neighboring mills in the cooperative.”
— Javier G., Plant Manager, Spain
Historical project · South Korea
CS-DC300
Korean K-beauty skincare brand
Need
Needed a soft-focus silica microsphere for cushion foundations without a heavy, cakey finish, and were frustrated by batch-to-batch particle-size variance from their existing supplier.
Solution
CS-DC300 (5–7 µm spherical silica, oil absorption 80–100 mL/100g) introduced as the sole powder-phase filler; three pre-formulation samples with PSD certificates let the lab run stability tests within the same month.
Results- Soft-focus panel score 4.2/5 vs 3.1/5 prior
- Batch-to-batch particle size CV 12% → under 4%
- Passed 3-month 45°C stability first attempt
- Adopted into 2 further SKUs within 6 months
“Every batch of CS-DC300 behaves the same in our oil-phase dispersion — no reformulation surprises. The blurring effect? Our sales team noticed before we told them.”
— Soo-jin L., R&D Formulator, South Korea
Food powder · Indonesia
CS-FC200
Indonesian seasoning manufacturer
Need
Severe caking in spice-blend sachets bound for humid export markets; caking-related returns from Malaysia and UAE distributors reached ~3.2% of export volume.
Solution
CS-FC200 food-grade anti-caking silica (BET 200 m²/g, FCC and EU 231-545-4 compliant) added at 0.6% to the top three export SKUs, validated with 40°C / 75% RH humidity-chamber tests on treated vs untreated samples.
Results- 4-week humidity test: treated free-flowing, control blocked
- Caking returns 3.2% → under 0.3%
- No taste/aroma impact (triangle test passed, n=60)
- Expanded to 7 further export SKUs within 12 months
“We export to 15 countries with very different climates. CS-FC200 is the first anti-caking agent that actually holds up across all of them.”
