Sodium saccharin, or sodium ortho-sulphobenzimide with molecular formula C7H4NNaO3S, is the salt form of saccharin, an artificial sweetener. It is available in anhydrous and di-hydrated form. It is an odorless, white powder. It is 300 to 500 times sweeter than sugar (sucrose). Major application of Sodium saccharin is the food industry as an additive in different products. It is used as a low calorie sweetener and stabilizer in a variety of food and drinks. In bakeries it is used to sweeten baked goods, breads, cookies and muffins. Due to it’s rapidly dissolving nature in water it is used as an artificial sweetener in carbonated beverages and sodas.
There are two main processes for making saccharin: First one is the Remsen-Fahlberg process and the second one is the Maumee, or Sherwin-Williams process, named upon the organization that further modified the Maumee process.
This process was named after the two scientists who discovered the sodium saccharine. In this process toluene is synthesized with chlorosulfonic acid to produce ortho and para-toluenesulfonyl chloride. Subsequent treatment with a potassium permanganate and ammonia forms the corresponding toluene sulfonamides.
In early 1950, a new process for saccharin production was developed by USA-based Maumee Chemical Company. Earlier saccharin is produced from anthracitic acid by continuous production process. After the merger of Maumee Chemical Company and PMC Specialties group, the process was improved to a batch process by using purified methyl anthranilate, as a starting material which naturally occurs in grapes.
In food industry it is used as non nutritive sweetener and stabilizer in a variety of food and cold drinks. In bakery industries it is used to sweeten baked goods, breads, cookies and muffins. In artificially sweetened diet drinks and sodas it is used because it is rapidly dissolved in water. Marzipan, plain, sweetened and fruit-flavored yogurt, jams/jellies and ice creams are the products that contain sodium saccharin.
Sodium saccharin is added to toothpastes and mouthwashes as a sweetening agent. Without adding sodium saccharin, toothpaste would have a bitter taste. Colgate uses sodium saccharin rather than natural sugar because it does not contribute to the production of decay causing acids.
In cosmetics and personal care products, Sodium Saccharin is used in the formulation of dental products, mouthwashes and lipstick as sweetener and flavoring agent.
Sodium saccharin is used as an intermediate chemical ingredient in the Herbicides and pesticide manufacturing. It is used as a catalytic agent in the manufacture of anaerobic adhesives an adhesive that stiffens without existence the oxygen. They are commonly known as sealants or locking compounds which are used to seal closed or secure fitting parts. Sodium Saccharin is used in pharmaceutical industry as a coating on drugs.
