👉 Common forms include flakes, granules, solid blocks, and liquid (30%–50% solution).
👉 Sodium hydroxide is a corrosive hazardous chemical (UN 1823/UN 1824) and must be transported in accordance with dangerous goods regulations.
👉 Yes, but food-grade sodium hydroxide (FCC/USP-compliant) must be used. It is primarily used as a food processing aid, such as in peeling and deacidification.
👉 It should be stored in a dry, ventilated, and sealed container. Avoid contact with acids and flammable materials to prevent moisture absorption and clumping.
👉 Mainly exported to Southeast Asia, Africa, the Middle East, Europe and South America, used in papermaking, textiles, water treatment and chemical production.
