Description

Potassium Hydroxide (KOH), also known as caustic potash, is a fundamental inorganic compound with the CAS registry number 1310-58-3. It serves as a powerful and versatile alkali, essential for a wide range of industrial chemical processes and manufacturing applications. This high-reactivity compound is a critical raw material for industries including chemical manufacturing, agriculture, food processing, and pharmaceuticals, where its strong alkaline properties are utilized for saponification, pH adjustment, catalysis, and cleaning.

Application

• Chemical Synthesis & Manufacturing: A key reagent in the production of potassium carbonate, phosphates, and other potassium salts.
• Soap & Detergent Production: Used as the primary alkali in the saponification of fats and oils to manufacture liquid soaps and soft soaps.
• Biodiesel Production: Acts as a catalyst in the transesterification process to convert triglycerides into biodiesel fuel.
• pH Regulation & Neutralization: Employed in water treatment, gas scrubbing, and industrial processes to control acidity and neutralize acidic waste streams.
• Electrolyte in Batteries: Used in alkaline batteries, such as nickel-cadmium (NiCd) and nickel-metal hydride (NiMH) cells.
• Food Processing (FCC Grade): Used as a food additive for pH control, peeling agent for fruits and vegetables, and in cocoa processing.
• Pharmaceutical & Cosmetic Ingredient: Utilized in the manufacture of certain pharmaceuticals and as a pH adjuster in cosmetic formulations.
• Industrial Cleaning: A component in heavy-duty cleaners and degreasers for industrial equipment.

Quality Control

Our Potassium Hydroxide is manufactured under strict quality management systems. We offer various grades, including Industrial, Technical, Food (FCC), and Pharmaceutical (USP/EP) grades, each meeting stringent purity and safety standards. Every batch undergoes comprehensive analytical testing. Certificates of Analysis (COA) detailing assay, impurity profiles, and physical specifications are available upon request to ensure compliance with your specific application requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed in a cool, dry, and well-ventilated area. Store away from acids, metals, and incompatible materials. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F).
