Safety Profile
Moderately toxic by intravenous and intraperitoneal routes. Mildly toxic by ingestion. Experimental reproductive effects. Questionable carcinogen with experimental neoplastigenic, tumorigenic, and teratogenic data. Human mutation data reported. When heated to decomposition it emits very toxic fumes of NazO, SOx, and NOx.
Toxicity
Sodium cyclamate is a non-nutritive sweetener that is about 30 times sweeter than cane sugar. The oral LD50s in rats and mice are 15.25 and 17.0 g/kg, respectively. It was banned as a food additive because of findings that it caused bladder cancer in rodents. It appears to act as a promoter. There is also evidence that it causes toxicity in the male reproductive system.
