A. Saccharin is used primarily as non-nutritive sweeteners.  The most common uses are in diet soft drinks, as a table-top sweetener, and in products, such as juices, sweets, chewing gum and jellies.  Saccharin is also used in cosmetics (e.g., toothpaste, mouthwash, and lipstick), pharmaceuticals (e.g., for coatings on pills), and electroplating (e.g., as a brightener in nickel-plating baths).
