Saccharin

Saccharin (CAS 81-07-2), also known as O-benzosulphimide, is a synthetic, non-caloric sweetener approximately 300–500 times sweeter than sucrose. It is used across food, pharmaceutical, and personal care industries.

This versatile ingredient serves as a sugar substitute and taste-masking agent. In food and beverage manufacturing, it is used in tabletop sweetener blends, diet soft drinks, and low-calorie confectionery where caloric reduction is required.

Pharmaceutical formulators rely on it to mask the bitter taste of active ingredients in oral syrups, chewable tablets, and liquid dosage forms. Personal care manufacturers incorporate it into toothpastes and mouthwashes.

These applications deliver sweetness without fermentable sugars. Industrial applications include its use as a corrosion inhibitor in electroplating baths, where it also acts as a brightening agent in nickel plating processes.

Saccharin is supplied as a white crystalline powder, and as the sodium or calcium salt form. Sodium saccharin is the most commercially traded form due to its significantly higher water solubility in various formulations.

Standard grades include Food Grade (FCC), USP, BP, and Ph. Eur., supporting use across regulated food, pharmaceutical, and cosmetic applications. Technical grade is available for industrial and electroplating applications.
