Potassium Hydroxide is a highly concentrated, caustic alkaline chemical available as a solid (pellets, flakes) or concentrated aqueous solution. It is a strong base widely used in industrial processes, chemical manufacturing, and as a reagent. Potassium Hydroxide provides excellent neutralizing, saponifying, and cleaning properties and is essential in producing potassium soaps, biodiesel, fertilizers, and various chemical compounds. Its high purity and concentration (90%) make it suitable for demanding applications requiring strong alkalinity.

Potassium Hydroxide

Primary Uses

Chemical Manufacturing

Used as a strong base and neutralizing agent in chemical syntheses and industrial processes.
Essential for manufacturing potassium soaps and detergents by saponification of fats and oils.
Utilized in biodiesel production as a catalyst in transesterification reactions.
Used in the production of potassium carbonate, potassium phosphates, and other potassium salts.

Food Industry

Used as a food-grade alkali for pH regulation and peeling in food processing (e.g., peeling fruits and vegetables).
Employed in cocoa and chocolate processing to alkalize cocoa products.

Water Treatment

Used to control water pH and neutralize acidic water in municipal and industrial treatment plants.

Agriculture

Raw material in the manufacture of potassium fertilizers and soil amendments.

Cleaning Products

Key ingredient in industrial cleaners, drain openers, and degreasers due to its strong alkaline properties.

Secondary Uses

Pharmaceuticals

Used in small quantities in drug formulations and pharmaceutical intermediates.

Battery Manufacturing

Employed as electrolyte in alkaline batteries and fuel cells.

Laboratory Reagent

Used extensively as a strong base in analytical chemistry and titrations.

Cosmetics

Used in controlled amounts for pH adjustment in some personal care products.
