Cyclamic acid is a synthetic sweetener that is around 30 to 50 times sweeter than sugar. It is widely used as a low-calorie sweetener in various food and beverage products. Cyclamic acid is also known by other names such as cyclohexylsulfamic acid, N-cyclohexylsulfamic acid, and cyclamate. Another synonym for it is calcium cyclamate, which is a calcium salt of cyclamic acid. Cyclamic acid and its salts are approved as food additives in many countries, including the United States, Europe, and Australia. Despite its approval, cyclamic acid has also faced controversy and was banned in some countries due to concerns about its safety.
