Acesulfame, a type of artificial sweetener, is more commonly known under the brand name Sweet One. However, there are a number of synonyms that can also be used to describe this sweetener. One such synonym is acesulfame potassium, which is the chemical name for the compound. Another synonym is Ace-K, which is a shorter, easier-to-remember version of acesulfame potassium. Some people may also refer to it simply as acesulfame or by its E number, E950. It's important to note that while acesulfame is a popular sweetener, it's not without controversy, and some studies have suggested that regular consumption of artificial sweeteners could have negative health effects.
