Tixosil® 68B FCC from Solvay is a food-grade precipitated amorphous silica developed to improve the flow and handling of powdered materials.
Its fine particle size and high internal porosity help reduce caking, absorb excess surface moisture, and keep compatible dry formulations free-flowing during blending, packaging, storage, and use. Tixosil 68B FCC meets the Food Chemicals Codex (FCC) monograph and is suitable for qualified food-grade applications.
Product type: Precipitated amorphous silica
Grade: FCC food-grade
Primary function: Anti-caking and free-flow aid
Median particle size: 15-22 µm specification
Packaging: 12.5 kg (27.56 lb) bag

Formulation and trial guidance
- Confirm the permitted use level and function under the regulations applicable to the finished product and market.
- Begin with controlled bench or production-line trials using the actual powder blend.
- Add the silica under sufficient mixing to achieve uniform distribution without generating excessive airborne dust.
- Evaluate flow rate, angle of repose, caking tendency, package emptying, moisture sensitivity, and finished-product appearance.
- Optimize the addition level rather than assuming that more silica will always provide better flow.
- Account for the product’s low bulk density when designing feeders, transfer systems, and storage capacity.
- Confirm compatibility with flavor, color, texture, dissolution, and labeling requirements in the finished formulation.
Regulatory note: FCC status does not by itself establish that every proposed application, dosage, label statement, or finished formulation is compliant. The formulator remains responsible for evaluating applicable regulations and qualifying the finished product.

- Keep away from excessive heat and reseal partially used packaging promptly.
- Do not stack flexible bulk bags unless the packaging and supplier instructions specifically permit it.
- Avoid generating airborne dust during transfer, blending, or cleanup.
- Ground transfer and conveying equipment because dry powder movement may generate electrostatic charge.
- Use local exhaust ventilation where dust may be generated.
- Wear safety glasses and suitable respiratory protection when required by airborne concentration and workplace conditions.
- Use protective gloves for prolonged or repeated contact.
- Clean spills using low-dust sweeping or suitable industrial vacuum equipment.

Questions & answers
What is Tixosil 68B FCC?
Tixosil 68B FCC is a precipitated amorphous silica developed to improve the free-flow properties and handling of compatible powdered products.
Is Tixosil 68B FCC suitable for food applications?
Solvay states that the product meets the FCC monograph and is suitable for food-grade applications. The finished formulation and use level must still comply with applicable regulations.
What does it do in a powdered formulation?
It helps reduce caking, improve powder flow, absorb limited surface moisture, and support more consistent blending, transfer, filling, and dispensing.
What is the median particle size?
The supplied COA specifies a D50 range of 15–22 microns. The representative lot tested at 18.4 microns.
What is the silica content?
The COA specification requires at least 94.0% SiO₂. The representative lot tested at 96.0%.
What is the pH?
The supplied COA specifies a pH range of 6.00–7.30 in a 5% suspension. The representative lot tested at pH 6.43.
Is it USP/NF or Ph. Eur. compliant?
The documentation currently available to Sorbents Direct confirms FCC status but does not establish USP/NF or Ph. Eur. compliance for this specific grade. Request confirmation before relying on those standards.
Can it be used in cosmetics or personal-care products?
Precipitated silica is used broadly in personal-care formulations, but suitability and regulatory status for a specific Tixosil 68B FCC application should be confirmed with current manufacturer documentation and formulation testing.
Is the product hazardous?
The supplied SDS does not classify it as hazardous under OSHA GHS. Airborne dust may still cause mechanical irritation, so dust control, eye protection, and appropriate respiratory protection should be used where needed.
What package size is available?
The standard Sorbents Direct package is one 12.5kg bag, equivalent to approximately 27.56lb. Pallet quantities are also available.
What documentation is available?
A Safety Data Sheet and lot-specific Certificate of Analysis are available. Contact Sorbents Direct if documentation is required before ordering.
