CAS 55589-62-3 Acesulfame Potassium Acesulfame K Ace-K Sugar Substitute



Acesulfame potassium (also known as Acesulfame K or Ace-K) is a high-intensity artificial sweetener. It is commonly used as a sugar substitute in a variety of food and beverage products.



Acesulfame potassium (E950) is a non-nutritive, calorie-free sweetener that is approximately 200 times sweeter than sucrose (table sugar). It is an odorless, white crystalline powder with a clean, sweet taste. Acesulfame K is chemically stable and can withstand high temperatures and a wide range of pH levels.


Data Sheet:

  • Chemical Formula: C?H?KNO?S
  • Molecular Weight: 201.24 g/mol
  • Appearance: White crystalline powder
  • Solubility: Highly soluble in water
  • Taste: Clean, sweet taste with a slight aftertaste
  • Heat Stability: Acesulfame K remains stable at high temperatures, making it suitable for use in baked goods and other heat-treated products.
  • pH Stability: Acesulfame K is stable over a wide range of pH levels, making it suitable for use in acidic or basic food and beverage products.


  1. High Sweetness: Acesulfame K is a high-intensity sweetener, meaning it provides a sweet taste at very low concentrations. Its sweetness is similar to that of other artificial sweeteners like aspartame and saccharin.
  2. Calorie-Free: Acesulfame K is non-caloric, meaning it provides negligible calories when consumed. It is often used as a sugar substitute in low-calorie or sugar-free products.
  3. Heat Stability: Acesulfame K retains its sweetness even at high temperatures, making it suitable for use in cooking, baking, and other food processing methods that involve heat.
  4. pH Stability: Acesulfame K remains stable over a wide range of pH levels, enabling its use in acidic and alkaline food and beverage applications.
  5. Synergistic Effect: Acesulfame K can be combined with other sweeteners, such as sucralose or aspartame, to create synergistic sweetening effects, enhancing the overall sweetness perception.


  1. Food and Beverages: Acesulfame K is used as a sweetener in a wide range of food and beverage products, including soft drinks, powdered drink mixes, desserts, baked goods, chewing gum, dairy products, and condiments.
  2. Tabletop Sweeteners: Acesulfame K is also used as a tabletop sweetener, available in individual packets or as a granulated form for consumers to add to beverages or food as a sugar substitute.
  3. Pharmaceutical Industry: Acesulfame K is used in pharmaceutical formulations to mask the bitter taste of certain medications or as a sugar substitute in sugar-free or low-calorie pharmaceutical products.
  4. Personal Care Products: Acesulfame K can be found in certain oral care products, such as toothpaste and mouthwash, to provide a sweet taste without contributing to tooth decay.
  5. Other Applications: Acesulfame K may also be used in dietary supplements, pet food, and other products where a low-calorie or sugar-free alternative is desired.
