Caustic Soda Flakes (chemical name: Sodium Hydroxide, NaOH) are a white, crystalline, hygroscopic substance used widely in industrial and chemical processes. They are the solid form of caustic soda, produced by evaporating liquid caustic soda into flakes.

• Chemical Formula: NaOH

• Appearance: White, opaque flakes

• Odor: Odorless

• Solubility: Highly soluble in water (exothermic reaction)

• Nature: Strong alkali (highly corrosive)

• Production of soaps and detergents

• Acid neutralization

• pH regulation

• Scouring and bleaching of cotton fabrics

• Mercerization of cotton

• Saponification of fats and oils

• Bauxite processing

• Pulp digestion and delignification

• Peeling of fruits and vegetables

• Cocoa processing

• pH adjustment

• Removal of heavy metals

• Corrosive: Avoid contact with skin, eyes, and clothing

• Protective Gear: Gloves, goggles, face shield, apron

• Storage:

  • In a dry, well-ventilated area

  • Away from moisture and acids

  • Use corrosion-resistant containers

• Commonly packed in:

  • 50 kg HDPE bags

• With inner liner to prevent moisture absorption

• Non-toxic in small concentrations but highly reactive

• Should be neutralized before disposal
