Saccharin sodium

Chemical properties

Saccharin sodium occurs as a white, odorless or faintly aromatic, efflorescent, crystalline powder. It has an intensely sweet taste, with a metallic or bitter aftertaste that at normal levels of use can be detected by approximately 25% of the population. The aftertaste can be masked by blending saccharin sodium with other sweeteners. Saccharin sodium can contain variable amounts of water.

The Uses of Saccharin sodium

Saccharin Sodium is a flavoring agent and non-nutritive sweetener. It is a salt of saccharin widely used as sweetener in food and beverage. As a high-intensity sweetener, Saccharin Sodium can be used in a wide variety of industries including: food production, beverage, cosmetics, agriculture/animal feed, and various other industries. Saccharin Sodium Salt Hydrate can be used for the purification of recombinant polypeptides, such as antibodies.

What are the applications of Application

Saccharin Sodium Salt is an inhibitor of the phosphotransferase and phosphohydrolase activities of glucose-6-phosphatase.

Production Methods

Saccharin is produced by the oxidation of o-toluene sulfonamide by potassium permanganate in a solution of sodium hydroxide. Acidification of the solution precipitates saccharin, which is then dissolved in water at 50℃ and neutralized by addition of sodium hydroxide. Rapid cooling of the solution initiates crystallization of saccharin sodium from the liquors.

Definition

ChEBI: Saccharin sodium is an organic molecular entity.

brand name

Sucaryl (Ross).

General Description

Saccharin sodium appears as odorless white crystals or crystalline powder. Aqueous solution is neutral or alkaline to litmus, but not alkaline to phenolphthalein. Effloresces in dry air. Intensely sweet taste. (NTP, 1992)

Air & Water Reactions

Water soluble.

Reactivity Profile

Saccharin sodium may react with oxidizing agents. . Very weak base in aqueous solution.

Hazard

The use of saccharin is being limited due to possible carcinogenicity.

Fire Hazard

Flash point data are not available for Saccharin sodium , but Saccharin sodium is probably combustible.

Pharmaceutical Applications

Saccharin sodium is an intense sweetening agent used in beverages, food products, table-top sweeteners, and pharmaceutical formulations such as tablets, powders, medicated confectionery, gels, suspensions, liquids, and mouthwashes. It is also used in vitamin preparations.
Saccharin sodium is considerably more soluble in water than saccharin, and is more frequently used in pharmaceutical formulations. Its sweetening power is approximately 300–600 times that of sucrose. Saccharin sodium enhances flavor systems and may be used to mask some unpleasant taste characteristics.
Injection of saccharin sodium has been used to measure the armto- tongue circulation time.

Safety Profile

Confirmed carcinogen with experimental carcinogenic, neoplastigenic, tumorigenic, and teratogenic data. Moderately toxic by ingestion and intraperitoneal routes. A promoter. Experimental reproductive effects. Human mutation data reported. When heated to decomposition it emits very toxic fumes of SOx, Na2O, and NOx.

Safety

There has been considerable controversy concerning the safety of saccharin and saccharin sodium in recent years; however, it is now generally regarded as a safe, intense sweetener. See Saccharin for further information.
The WHO has set a temporary acceptable daily intake of up to 2.5 mg/kg body-weight for saccharin, including its salts.(3) In the UK, the Committee on Toxicity of Chemicals in Food, Consumer Products, and the Environment (COT) has set an acceptable daily intake for saccharin and its salts (expressed as saccharin sodium) at up to 5 mg/kg body-weight.
LD50 (mouse, oral): 17.5 g/kg
LD50 (rat, IP): 7.1 g/kg
LD50 (rat, oral): 14.2 g/kg

Potential Exposure

The information provided has to do, primarily, with the manufacturing of saccharin. Saccharin has been used as a nonnutritive sweetening agent. At one point the United States consumption pattern for all forms of saccharin has been estimated as 45% in soft drinks; 18% in tabletop sweeteners; 14% in fruits, juices, sweets, chew- ing gum, and jellies; 10% in cosmetics and oral hygiene products; 7% in drugs, such as coating on pills; 2% in tobacco; 2% in electroplating; and 2% for miscellaneous uses. Human exposure to saccharin occurs primarily through ingestion because of its use in many dietic foods and drinks and some personal hygiene products, including toothpastes and mouthwashes. The general public is exposed to saccharin, especially by persons required to reduce sugar intake.

storage

Saccharin sodium is stable under the normal range of conditions employed in formulations. Only when it is exposed to a high temperature (125℃) at a low pH (pH 2) for over 1 hour does significant decomposition occur. The 84% grade is the most stable form of saccharin sodium since the 76% form will dry further under ambient conditions. Solutions for injection can be sterilized by autoclave.
Saccharin sodium should be stored in a well-closed container in a dry place.

Incompatibilities

Dust may form explosive mixture with air. Incompatible with strong oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, and epoxides.

Incompatibilities

Saccharin sodium does not undergo Maillard browning.
