Industrial & Food Grade Potassium Hydroxide CAS 1310-58-3 Caustic Potash

Potassium Hydroxide (Caustic Potash, KOH, CAS:1310-58-3,EINECS:215-181-3, HS Code:28152000, molecular formula KOH, MW: 56.11) is white flake, pellet or stick solid. It is manufactured by electrolysis of potassium chloride solution followed by professional refining. We supply industrial grade and food grade products that comply with GB, FCC and international quality standards. This product features strong hygroscopicity, dissolves rapidly in water with obvious heat release and is also soluble in ethanol. Its aqueous solution presents strong alkalinity and corrosivity. As a fundamental inorganic strong alkali, it is extensively applied in chemical synthesis, electroplating, food processing, daily chemicals, textile and wastewater treatment industries.
