Soda Ash Light, or Light Sodium Carbonate (Na₂CO₃), is a fine, white, powdery substance used extensively in detergents, soaps, dyes, water treatment, textiles, and chemical manufacturing. It has lower bulk density compared to soda ash dense, making it ideal for applications where fast solubility and easy mixing are important. Though non-toxic, it is mildly alkaline and may irritate skin or eyes upon contact, so standard safety precautions should be followed during handling.
