Potassium Hydroxide 90%
Potassium Hydroxide 90% 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.
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.

Phosphoric acid Technical Grade
Product Description
Phosphoric Acid Technical Grade is a concentrated, inorganic acid primarily used in industrial applications. It typically contains minor impurities compared to food or pharmaceutical grades but maintains excellent performance as an acidulant, rust remover, and intermediate chemical. This grade is widely used in manufacturing fertilizers, detergents, metal treatment, and other industrial processes where high purity is not critical but effective acidic properties are required.
