Caustic Soda Flakes — Sodium Hydroxide (NaOH)

Formula: NaOH | Purity $\geq 98\%$ | Industrial Grade | Supplier: MizanPetroGas

Product Introduction

Caustic Soda Flakes or Sodium Hydroxide with the chemical formula NaOH is a solid, white, odorless, and strongly alkaline ionic compound supplied in the form of crystalline flakes. This widely used material has a molecular weight of 39.997 g/mol, a melting point of approximately 318°C (591 K), and an extremely high boiling point of 1,388°C.

Sodium hydroxide is highly soluble in water (1,110 g/L at 20°C), and its dissolution process is strongly exothermic — such that the temperature of the solution can rapidly exceed 100°C. It has an intensely bitter taste and creates a slippery, soapy sensation upon contact due to its saponification reaction with skin fats.

As one of the most extensively utilized strong industrial bases with a $\text{pH} \approx 14$, caustic soda plays an indispensable role in the raw material supply chain of the chemical, petrochemical, pharmaceutical, food, textile, and water treatment industries. MizanPetroGas Company supplies and distributes this strategic product with $\geq 98\%$ purity in 25 kg multi-layer, moisture-resistant industrial bags.

Applications and Target Industries

With an impressive operational scope, sodium hydroxide is utilized as one of the world’s top 7 basic chemicals across multiple industries:

Safety and Storage Conditions

• Personal Protective Equipment (PPE): Splash-proof chemical safety goggles, full face shield, chemical-resistant gloves (neoprene or PVC), protective overalls, and rubber safety boots are mandatory.
• Ventilation: Operate in environments with adequate ventilation — flake dust severely irritates the respiratory tract.
• Exothermic Reaction with Water: Never add water to caustic soda — always add caustic soda slowly to water to prevent explosive boiling and splashing of hot concentrated solution.
• Incompatibilities: Store away from acids, active metals (aluminum, zinc, tin, magnesium), flammable organic materials, and ammonium compounds — reaction with active metals produces hydrogen gas ($H_{2}$ – flammable and explosive).
• Storage Containers: Multi-layer tear- and moisture-resistant bags — dry, cool, well-ventilated warehouse — protected from moisture and rain — maximum 6 rows stacking height.
• First Aid: Skin contact: Flush immediately with abundant water for $\geq 15$ minutes + remove contaminated clothing. Eye contact: Rinse immediately for $\geq 15$ minutes + seek urgent emergency ophthalmic care. Ingestion: Never induce vomiting — drink large volumes of water + seek immediate emergency medical care.
