The ability of a substance to remain free-flowing is crucial in many industrial and food applications. Sodium Ferrocyanide (CAS 14434-22-1), a key chemical supplied by NINGBO INNO PHARMCHEM CO.,LTD., serves as an effective anticaking agent by leveraging specific chemical principles. Understanding this mechanism is beneficial for formulators and product developers looking to optimize their products.

Salt, particularly table salt, is hygroscopic, meaning it absorbs moisture from the atmosphere. When salt crystals absorb moisture, a thin layer of brine forms on their surface. As humidity fluctuates, this brine can dissolve some salt and then recrystallize upon drying. This recrystallization process can bind individual salt crystals together, leading to clumping or caking. This phenomenon significantly impairs the pourability and handling of the salt.

Sodium Ferrocyanide intervenes in this process through its unique chemical structure and charge. The ferrocyanide ion, [Fe(CN)6]4−, carries a substantial negative charge. When incorporated into the sodium chloride crystal lattice, it creates an imbalance. To maintain electrical neutrality within the growing salt crystal, the incorporation of the ferrocyanide ion necessitates specific structural accommodations, such as sodium vacancies. These accommodations are energetically unfavorable for the bulk crystal lattice.

As a result, ferrocyanide ions tend to segregate to the surface of the growing salt crystals. This surface adsorption inhibits further crystal growth and, crucially, prevents the formation of interparticle bridges that cause caking. Essentially, the ferrocyanide coating acts as a physical barrier, reducing the likelihood of salt crystals adhering to each other. The strong binding of the cyanide to iron also ensures that the ferrocyanide itself does not readily desorb from the surface, providing a lasting anticaking effect.
