Calcium Silicate (Food Grade Anti-Caking)
CAS Number: 1344-95-2
Food-grade calcium silicate (E552) is a synthetic amorphous inorganic material with exceptionally high water absorption capacity (up to 3× its own weight), used as an anti-caking agent in table salt, baking powder, and food powders. Its porous structure rapidly absorbs moisture while maintaining powder flowability. Compared to silicon dioxide, it offers higher water-holding capacity and is preferred in high-humidity applications.

| CaO content (%) | 27–37 |
| SiO2 content (%) | 50–65 |
| heavy metals (ppm) | ≤30 |
| moisture absorption capacity | ≥300% (weight/weight) |
Applications
- Table salt and sea salt anti-caking agent
- Baking powder and leavening dry blend flowability
- Onion, garlic, and vegetable powder anti-caking
- Egg powder and milk powder moisture control
- Industrial floor absorbent and desiccant (food plant)
Key Features
- Superior water absorption capacity versus silica-based anti-caking agents
- Maintains powder flowability even in high-humidity environments
- Chemically inert with no impact on product taste or nutrition
- EU E552 approved, GRAS status, FCC grade available
