Quick selection
- Structure and cleaning balance
- CENSIL 310
- Higher surface area route
- CENSIL 320
- Fine powder, appearance-led
- CENSIL 150
Where we add value
- Set up a joint test path across cleaning performance, paste structure and consumer feel.
- Reduce syneresis, phase separation and appearance instability by comparing materials of different surface area, purity and pore structure.
- Start from a single small-sample validation and expand to multi-SKU paste projects.
Who this track serves
- Toothpaste plants with formulation, compounding and filling capability.
- Local brand manufacturers, OEM / ODM and private-label filling operations.
- Oral-care customers developing multiple SKUs who are willing to run material screening.
Grades on this track
Candidate routes across different surface areas, purities and pore structures. Oral care is a formulation-led track — selection is confirmed by RDA, viscosity and stability testing on your own paste, not by a datasheet.
We publish the selection logic, not the numbers. Data sheets are issued per enquiry so the figures match the current supplier revision and your application.
Typical values for orientation only, not a specification. The current supplier technical data sheet governs for quotation, COA and customer testing — request it for the grade you are evaluating.

| Test dimension | What to watch | What it tells you |
|---|---|---|
| Cleaning / abrasion | Whether it meets the product positioning | Tells you if the cleaning route fits |
| Paste structure | Viscosity, thixotropy and extrusion behaviour | Tells you filling and use experience |
| Appearance and feel | Fineness, uniformity and mouthfeel | Tells you the consumer experience |
| Storage stability | Syneresis, separation or structural collapse | Tells you the scale-up risk |
Where we sit against the reference brands
Reference points include Evonik ZEODENT® (113, 165), PQ Corporation dental / toothpaste silica series, and Solvay specialty oral-care silica.
How we approach it
Decide first whether the customer wants to improve cleaning, paste structure or long-term stability, then choose the silica route and set up a formulation trial.
