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.

A natural vegetable oil extracted from the seeds of the Ricinus communis plant.
Thick, pale yellow liquid with a mild odor.
Contains high levels of ricinoleic acid (~85–90%).
Known for its viscosity, moisturizing, anti-inflammatory, and lubricating properties.
Castor oil is obtained from the fruit seed of castor (Ricinus communis L.) a large shrub that grows mainly in India, Brazil and China. The seed has an oil content of 40-50%. The dehydration process removes the OH group (dehydroxylation) of ricinoleic acid and turns it into linoleic acid.
