Potassium chloride is a white crystalline or colorless granular material. It is odorless, stable in air and highly soluble in water. In addition to USP- and FCC-certified grades, we also offer those with BP, EP and JP certifications. Special grades include those that resist caking and separation in blends with sodium chloride, as well as those for microencapsulation. We also can customize potassium chloride for particle size, flavor enhancer content and other customer requirements.
