Sodium cyclamate, the second oldest artificial sweetener, which has the least sweetness – about 30 times sweeter than sucrose and with the European food additive number E952(ii). This non-caloric sweetener can be used as a sugar substitute to reduce calorie and sugar intake in table-top sweeteners, soft drinks, baked goods, confections, and preserves.

It has been banned for human consumption in the USA due to the potential side effects of cancer by the U.S. Food and Drug Administration since 1970.
