Basic Information

Sodium Hydroxide

Sodium hydroxide, or caustic soda, is a white, deliquescent solid and strongly alkaline base that dissolves readily in water, methanol and ethanol. Its high reactivity supports neutralization, saponification, alkaline cleaning and conversion to sodium salts. It is used in pulp and paper, textile, soap and detergent, dye, plastic, rubber, pharmaceutical and inorganic-salt manufacture. Other applications include metal processing, water electrolysis, laboratory reagents and industrial or household drain cleaning.
