  • Applications

    Acesulfame potassium (CAS 55589-62-3) is a zero-calorie, heat-stable artificial sweetener widely used to sweeten foods and beverages without adding calories. Typical applications include beverages (soft drinks and flavored drinks), confectionery and bakery items, dairy products and dairy-derived formulations to improve flavor, chewing gum and other candies, and pharmaceutical formulations (syrups and lozenges) where sweetness is desired; it is also used in some personal care and oral care products (such as toothpaste and mouthwash) to provide sweetness without sugar.
