product description

Products Description of Potassium Hydroxide CAS#1310-58-3

Potassium hydroxide (KOH/caustic potash) is a strong inorganic base soluble in polar solvents to form alkaline acid-neutralizing solutions. It finds broad use in soft soaps, cleaning, wood treatment, dyes, CO₂ absorption, potassium salts, titrations and organic synthesis.


Product Application of Potassium Hydroxide CAS#1310-58-3

Potassium hydroxide serves as an emulsifier in lotions and alkaline agent in personal care products. It is used in potassium salt manufacturing, electroplating, lithography, inks, wood treatment, organic synthesis and chemical analysis. Highly alkaline, concentrated solutions can cause skin burns and require careful handling.
