Saccharin is widely used as an artificial sweetener in various food and beverage products due to its intense sweetness and zero-calorie content. It is commonly found in diet sodas, sugar-free gum, tabletop sweeteners, and processed foods where sugar reduction is desired. Because it does not promote tooth decay, it is also used in toothpastes and mouthwashes. In addition to consumer products, saccharin serves as a flavoring agent in pharmaceuticals, helping to mask the bitter taste of certain drugs. Its stability under heat makes it suitable for use in baked goods and other products requiring high-temperature processing.
