Product Details
Sodium hydroxide (caustic soda) is a strong inorganic base with wide industrial applications. It appears as white, odorless flakes or crystals that are highly hygroscopic and readily absorb moisture and carbon dioxide from air. It is highly soluble in water, releasing significant heat during dissolution, and also soluble in maleic-anhydride.html">material/ethanol.html">ethanol and glycerol. This product is widely used in chemical manufacturing, soap making, paper production, textile processing, food industry, and water treatment applications. It must be handled with proper protective equipment due to its strong corrosive properties.
