Pure saccharin tastes several hundred times as sweet as sugar. It is not readily soluble in water, but its sodium salt, which is sold commercially, dissolves readily. Saccharin has no nutritional value and is excreted unchanged by the body. It is used as a sweetener by persons who must limit their consumption of sugar. Despite the fact that saccharin causes cancer in laboratory rats, its ban was rescinded after a public outcry.

It is sweet but has a bitter aftertaste. The crystal hydrate of the sodium salt of saccharin, known as Crystallose, has a higher solubility in water (1:1.5). Saccharin is obtained commercially by the oxidation of o-toluenesulfonamide. With a sweetness 400–500 times that of sugar, saccharin was formerly used in great quantities as a sugar substitute. It is not assimilated by the body but rather is excreted in the urine. Saccharin is used as a sweetener for certain items, such as toothpaste, and as an additive in electroplating technology. saccharin[′sak·ə·rən]saccharinsaccharinsaccharin[sak´ah-rin]sac·cha·rin(sak'ă-rin),saccharinThe cyclic imine of 2-sulfobenzoic acid, which is 500 times sweeter than sugar, used as an artificial sweetener.Saccharin causes bladder tumours in rats if given in “mega” doses, and was temporarily withdrawn from the market; one pack of Sweet ‘n Low (a sugar substitute) contains 40 mg of saccharin. saccharinNutrition A cyclic imine of 2-sulfobenzoic acid, which is 500 times sweeter than sugar, and used as an artificial sweetener.
