Description

Sodium Ferrocyanide is an inorganic salt widely recognized for its role as a safe and effective anti-caking agent in food-grade salt. This compound is valued for its ability to prevent clumping without altering the taste or properties of the final product, ensuring consistent quality and free-flowing characteristics. It is an essential processing aid for industrial salt producers, food manufacturers, and in specific niche chemical synthesis applications where cyanide ion sequestration is required.

Application

• Primary use as an anti-caking agent (E535) in food-grade and table salt.
• Processing aid in the production of industrial and road de-icing salts to maintain free-flowing properties.
• Precursor in the manufacturing of pigments, such as Prussian blue.
• Used in metallurgical processes for metal hardening and surface treatment.
• Employed in the synthesis of other ferrocyanide and ferricyanide compounds.
• Laboratory reagent for analytical chemistry and as a stabilizer in specific chemical formulations.

Quality Control

Our Sodium Ferrocyanide is manufactured under a strict quality management system. Production adheres to relevant food additive specifications, including FCC (Food Chemicals Codex) and EU food-grade standards (E535). Every batch is tested to ensure compliance with stringent purity and safety requirements. A comprehensive Certificate of Analysis (COA) detailing assay, impurity limits, and physical parameters is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep the original container tightly sealed to prevent caking due to moisture absorption. Separate from strong acids.
