Sodium Saccharin
Sodium Saccharin is a white crystalline powder or granule with the chemical formula C₇H₄NNaO₃S·2H₂O. It is the sodium salt of saccharin, an artificial sweetener approximately 300–500 times sweeter than sucrose. This non-nutritive, zero-calorie sweetener is widely used in food, beverage, pharmaceutical, and personal care industries. Packaged in 25kg containers, it is highly soluble in water, heat-stable, and has excellent shelf life, making it a cost-effective and versatile sweetening agent.
