Our Sodium Hydroxide (Caustic Soda Flakes) is a high-purity, industrial-grade alkali used extensively across multiple industries. Manufactured under strict quality control parameters, our caustic soda meets international standards and specifications.
Also known as lye or caustic soda, sodium hydroxide is a highly versatile chemical with a wide range of industrial applications. It is a white, solid, highly caustic metallic base and alkali salt. We supply caustic soda in flake form, which is preferred for ease of handling and dissolution.
Every batch undergoes rigorous quality testing in certified laboratories to ensure consistency and compliance with specifications. We provide complete documentation including Certificate of Analysis (COA), Material Safety Data Sheet (MSDS), and Technical Data Sheet (TDS) with every shipment.

⚠️ WARNING: Highly Corrosive Material
Sodium Hydroxide is a highly corrosive substance. Proper safety precautions must be followed during handling, storage, and use. Always refer to the complete MSDS before handling.
Non-combustible. However, contact with water generates heat and may cause spattering. Use dry chemical, CO₂, or water spray to fight fires involving caustic soda. Wear full protective equipment including self-contained breathing apparatus.

| Contact Person | Mr. Dinesh Lunkad |
| Eye Contact | Immediately flush with water for at least 15 minutes lifting the upper and lower eyelids intermittently. See a medical doctor or ophthalmologist as necessary. |
| Skin Contact | Wash with plenty of soap and water. Get medical attention if irritation occurs and persists |
| Inhalation | Remove to fresh air. If breathing difficulty or discomfort occurs and persists, obtain medical attention. |
| Ingestion | Rinse mouth with water. Dilute by giving 1 or 2 glasses of water. Do not induce vomiting. Never give anything by mouth to an unconscious person. Contact a doctor or poison control center. |
| Advice to Physician | While internal toxicity is low, irritant effects of high concentrations may produce corneal opacities, and vesicular skin reactions in humans with abraded skin only. Treatment is symptomatic and supportive. |
Soda ash is produced in three principal grades: Dense, natural light and synthetic light soda ash. When these products are mixed in water they may be known as liquid soda ash. These grades differ only in physical characteristics such as bulk density and size and shape of particles, which influence flow characteristics and angle of repose. Other physical properties, as well as chemical as chemical properties of solutions, are common to each grade of soda ash.
