Product Description
Sodium Carbonate (Anhydrous), commonly known as soda ash or washing soda, is a high-purity alkaline salt widely used in food processing, laboratory chemistry, water treatment, and industrial manufacturing. Supplied in its anhydrous form, this material offers high reactivity, excellent solubility, and long-term stability under appropriate storage conditions.
Its strong alkalinity makes it suitable for pH regulation, buffer preparation, neutralisation reactions, and formulation processes. Ausamics Sodium Carbonate is manufactured to deliver consistent purity (≥99%), ensuring reproducible performance across technical and regulated applications.
