Saccharin

What is Saccharin?

Saccharin is a white, crystalline artificial sweetener, chemically a sulfonamide derived from o-toluenesulfonamide, known for its intense sweetness—300 to 500 times that of sugar—without contributing calories or fermentability. Developed in the late 19th century, it appears in cosmetic products primarily within the oral care category, such as toothpastes, mouthwashes, and chewing gums. Here, it functions by delivering a persistent sweet sensation that boosts palatability, encouraging consistent use. Its high potency allows minimal amounts to effectively counterbalance bitter or astringent notes from therapeutic agents like sodium fluoride or essential oils. In lip balms and select fragranced formulations, it refines the sensory profile by overlaying agreeable taste cues. Stable across pH ranges and temperatures encountered in production and storage, saccharin integrates seamlessly without altering product texture or shelf life, supporting clean-label, sugar-free claims.
