Description

Syloid 266 is a high-purity, synthetic amorphous silica. This versatile material is engineered to deliver exceptional performance as a flow aid, anti-caking agent, and carrier in demanding industrial and pharmaceutical applications. It is particularly valued for its ability to improve powder handling and processing efficiency. Key industries that rely on this product include pharmaceuticals, food, cosmetics, and industrial chemical manufacturing.

Application

• Pharmaceutical Excipient: Widely used as a glidant and anti-adherent in tablet and capsule formulations to ensure uniform powder flow and prevent sticking during compression.
• Food Additive (Anti-caking Agent): Prevents clumping and maintains free-flowing properties in powdered food products such as spices, seasonings, and drink mixes.
• Carrier for Active Ingredients: Acts as an inert, high-surface-area carrier for flavors, fragrances, and active pharmaceutical ingredients (APIs) in liquid and solid dosage forms.
• Cosmetics and Personal Care: Functions as a viscosity modifier, absorbent, and texturizing agent in powders, creams, and lotions.
• Industrial Coatings and Inks: Used as a flatting agent and rheology modifier to control gloss and improve suspension stability.
• Chemical and Catalyst Support: Serves as a high-purity support medium for catalysts and as a processing aid in various chemical syntheses.

Quality Control

Our Syloid 266 is manufactured under strict quality management systems to ensure batch-to-batch consistency and reliability. The product is tested against stringent specifications for purity, particle size, and performance characteristics. While it is suitable for use in applications requiring high-quality standards, specific compliance with USP-NF, Ph. Eur., or FCC monographs should be confirmed for your intended use. A comprehensive Certificate of Analysis (COA) is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive). To maintain optimal performance and prevent caking, the container must be kept tightly sealed after each use to minimize exposure to atmospheric humidity.
