Calcium Saccharin is formed by neutralizing saccharin with a calcium base, producing the calcium salt in place of the far more common sodium version. It is generally isolated as a hydrate, giving the formula C₁₄H₈CaN₂O₆S₂·3.5H₂O and a molecular weight of about 467.48 g/mol, and presents as a white, water-soluble crystalline solid. The sweetness comes from the same imide-sulfonyl ring system found in all saccharin salts; the compound is not broken down metabolically, so it contributes essentially no calories.
Because it substitutes calcium for sodium, Calcium Saccharin is the salt of choice whenever a formulator needs saccharin’s sweetening effect but wants to avoid adding to a product’s sodium content.
Calcium Saccharin functions primarily as a sugar-replacement sweetener across food, beverage, and pharmaceutical applications where a low-calorie or reduced-sodium profile matters. It shows up in tabletop sweetener blends, diet beverages, and reduced-sugar food products, often paired with other high-intensity sweeteners.
In pharmaceutical manufacturing, it is used as a sweetening and taste-masking agent in chewable tablets, oral suspensions, syrups, and effervescent formulations — particularly for patients who need to limit sodium intake.
Recommended PPE: Chemical-resistant gloves and eye/face protection should be worn when handling. Avoid generating or inhaling dust. Store in a tightly closed container in a cool, dry area away from incompatible materials.
