In April 2010, the EPA announced that there is sufficient data to support the removal of saccharin and its salts from the agency’s lists of hazardous wastes, hazardous constituents, and hazardous substances through the Resource Conservation and Recovery Act (RCRA) and the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). These substances no longer meet the criteria for hazardous waste regulation.
Saccharin is a white crystalline powder that is about 300 times sweeter than sucrose. It is typically available in the acid form (saccharin) or as salts (sodium saccharin or calcium saccharin). The most common uses are in diet soft drinks, table-top sweeteners, syrups, juices, chewing gums, and jellies. It is also used in personal-care products (e.g. toothpaste, mouthwash, dental cleaners, lipstick), pharmaceuticals (e.g. coatings on pills), and electroplating (e.g. brightener in nickel-plating baths).
