DESCRIPTION
E552 Calcium Silicate is a porous inorganic material that can adsorb water and some oils, and E552 Calcium Silicate prevents powder particles from sticking together by reducing surface moisture and improving flow.
E552 Calcium Silicate is commonly manufactured as a precipitated or synthetic calcium silicate with controlled surface area and particle morphology, and these physical properties determine its anti-caking effectiveness.
E552 Calcium Silicate works primarily as a physical anti-caking agent, and E552 Calcium Silicate does not dissolve in the finished powder but remains as a fine dispersed solid.
E552 Calcium Silicate is typically used at low levels, and dosage must be optimized to balance flow improvement with appearance and mouthfeel considerations in the final product.
E552 Calcium Silicate should be used according to applicable food additive regulations and good manufacturing practices for the target market.
E552 Calcium Silicate should be handled with dust control practices because fine mineral powders can become airborne during transfer and blending.
E552 Calcium Silicate is stable under typical storage conditions, but E552 Calcium Silicate can pick up moisture from the environment, so packaging moisture barrier performance affects long-term stability.
E552 Calcium Silicate should be stored in tightly closed containers in a dry place to preserve adsorption capacity.
E552 Calcium Silicate should be kept away from strong acids because acids can react with silicates and change properties.
E552 Calcium silicate is a calcium salt of silicic acid used as a food additive primarily for anti-caking and flow improvement.
E552 Calcium silicate is typically supplied as a white, porous, lightweight powder with high oil and moisture adsorption capacity.
E552 Calcium silicate improves flow by absorbing surface moisture and reducing inter-particle adhesion in powders.
E552 Calcium silicate is widely used in powdered foods such as salt, spices, seasonings, and dry mixes to prevent clumping.
E552 Calcium silicate is also used in supplements and some pharmaceutical solids as a processing aid to improve powder handling.
E552 Calcium silicate is an important industrial material used in insulation boards, fire protection products, and as a functional filler in composites.
E552 Calcium silicate performance depends on particle structure, porosity, bulk density, and the formulation environment.

Rinse cautiously with water for several minutes.
Remove contact lenses if present and easy to do, then continue rinsing.
Seek medical attention if irritation persists.
Ingestion:
Rinse mouth with water.
Seek medical attention if discomfort occurs.
Never give anything by mouth to an unconscious person.
Note to Physicians:
Treat symptomatically.
No specific antidote is required.
Provide supportive care as needed.
HANDLING AND STORAGE
Handling:
Use appropriate PPE including gloves and safety glasses for bulk handling.
Avoid generating dust and avoid inhalation of fine powder.
Use closed transfer or local exhaust to minimize airborne dust during dosing and mixing.
Ventilation:
Use general ventilation for normal handling.
Use local exhaust where dust may be generated during powder transfer.
Minimize airborne particulate accumulation in enclosed areas.
Storage:
Store in tightly closed containers in a cool, dry place.
Protect from moisture to preserve adsorption capacity and prevent caking of the additive itself.
Keep away from strong acids and incompatible chemicals.
Spill and Leak Procedures:
Sweep up spilled powder and avoid dust generation.
Collect into suitable containers for reuse or disposal according to local regulations.
Clean residues with water if needed and dry the area to prevent slip hazards.
Handling Precautions:
Optimize dosage because E552 Calcium Silicate strongly affects flow and excessive levels can influence appearance or mouthfeel in some powdered foods.
Control moisture exposure because E552 Calcium Silicate works by adsorption and can lose effectiveness if it absorbs moisture before use.
Rotate stock using FIFO practices to maintain consistent quality and predictable anti-caking performance.
