Sodium Metabisulphite (SMS) is an inorganic compound with the chemical formula Na₂S₂O₅. It appears as a white to slightly yellow crystalline powder with a characteristic sulfur dioxide odor. Due to its excellent antioxidant and antimicrobial properties, it is widely used across the food, pharmaceutical, chemical, textile, leather, and water treatment industries.

In the food industry, Sodium Metabisulphite is commonly used as a preservative (E223) and antioxidant to help prevent discoloration, inhibit microbial growth, and extend the shelf life of selected food products where permitted by food regulations.

In industrial applications, it functions as a reducing agent, bleaching agent, dechlorinating agent, and oxygen scavenger, making it valuable in textile processing, leather treatment, photographic chemicals, water treatment systems, mining, and chemical manufacturing.

Our Sodium Metabisulphite is suitable for commercial and industrial applications. Users should always follow the recommended dosage, safety guidelines, and applicable local regulations according to the intended application.
