Sodium Saccharin

What is Sodium Saccharin?

Sodium saccharin is the sodium salt of saccharin, a synthetic compound first synthesized in 1879 through oxidation of o-toluene sulfonamide, resulting in a white, odorless crystalline powder (C7H4NNaO3S). It delivers 300-500 times the sweetness of sucrose without calories or fermentability by oral bacteria. In cosmetics, it appears mainly in rinse-off oral care formulations like toothpastes, mouthwashes, and some lip balms. Functionally, it imparts a clean, lingering sweet taste that boosts product appeal, neutralizes bitter or medicinal aftertastes from actives like fluorides, and synergizes with flavors for a refreshing sensory profile, all without contributing to plaque or decay.
