Potassium Acesulfame
What is Potassium Acesulfame?
Potassium acesulfame, commonly known as acesulfame potassium or Ace-K, is a synthetic, non-nutritive sweetener derived from the potassium salt of 6-methyl-1,2,3-oxathiazine-4(3H)-one 2,2-dioxide. Developed in the late 1960s, it delivers intense sweetness approximately 200 times greater than sucrose without contributing calories or promoting tooth decay. In cosmetics, it appears mainly in oral hygiene formulations like toothpastes, mouthwashes, and dental floss, as well as lip balms and glosses. Its primary function is to impart a clean, sugar-like sweetness that boosts palatability, encouraging consistent use, while effectively covering bitter or medicinal aftertastes from active ingredients such as fluorides or antimicrobials. Heat-stable and pH-tolerant, it maintains efficacy in various product matrices without altering texture or appearance.
