In formulations for electroplating-bath brighteners、A sweetening agent in Aromatic Cascara Sagrada Fluid extract and highly alcoholic preparations. ... It is used as a sweetening agent in vehicles、canned foods、and beverages and in diets for diabetics to replace sucrose.、Add sweetness with or without the extra calories ...、in、beverages、baked goods、confections、table-top sugar、substitutes、many processed foods、NON-CALORIC SYNTHETIC SWEETENER IN TABLETS、LIQ PRODUCTS、SOFT DRINKS、DIETETIC FOODS、MISC PHARMACEUTICALS、CHEWING GUM、TOOTH PASTE、SMOKELESS TOBACCO PRODUCTS、ELECTROPLATING BATH ADDITIVE、CATTLE FEED ADDITIVE、ANTISEPTIC (FORMER USE)、PRESERVATIVE TO RETARD FERMENTATION OF FOOD (FORMER USE).、Saccharin has been used in the sweetening of pharmaceutical tablets and in processing of tobacco.、Use Classification: Fragrance Ingredients、Food Additives -> SWEETENER -> JECFA Functional Classes、Environmental transformation -> Pesticide transformation products (metabolite、successor)、Cosmetics -> Masking、Oral care、Consumer Uses: Not Known or Reasonably Ascertainable、Household Products: Information on 2 consumer products that contain Saccharin in the following categories is provided:、• Home Maintenance、• Personal Care、Methods of Manufacturing: In most countries、commercial saccharin is produced by the Remsen-Fahlberg process ... Toluene is used as the starting material and reacted with chlorosulfonic acid to a mixture of isomeric toluene sulfochlorides. In the presence of ammonia、2-toluene sulfochloride forms 2-toluene sulfonic acid amide which is oxidized under appropriate conditions to saccharin. Potential oxidizing agents are potassium permanganate or chromic acid.、In the United States、the Maumee process is used. This starts from either anthranilic acid or its methyl ester、which can be obtained from phthalic acid anhydride. With sodium nitrite、anthranilic acid forms a diazonium compound、which is reacted with sulfur dioxide or sulfites、and chlorinated to 2-chlorosulfonylbenzoic acid methyl ester. In the presence of ammonia、this ester yields the respective amide、from which、after de-esterification、saccharin is obtained. Reaction with sodium hydroxide or calcium hydroxide forms the respective saccharin salts.、Saccharin is dissolved in an equimolar quantity of aqueous sodium hydroxide、and the solution is concentrated to crystallization.、Saccharin sodium、Saccharin is reacted with a semimolar quantity of calcium hydroxide in aqueous medium、and the resulting solution is concentrated to crystallization.、Saccharin calcium、A mixture of toluenesulfonic acids is converted into the sodium salt then distilled with phosphorus trichloride and chlorine to obtain the o-toluene sulfonyl chloride which、by means of ammonia、is converted into o-toluenesulfamide. This is oxidized with permanganate、treated with acid、and saccharin crystallized out.、Impurities: o- & p-Toluenesulfonamide、1、2-benzisothiazol-1、1-dioxide、2-benzisothiazoline-1、3-aminobenzisothazol-1、5- & 6-chlorosaccharin、ammonium saccharin、methyl saccharin、diphenyl sulfone、ditolylsulphone isomers、o- & p-sulfamoylbenzoic acid、o-chlorobenzoic acid、o-sulfobenzoic acid (& ammonium salt)、n-tetracosane、bis(4-carboxyphenyl)sulfone、toluene-2、4-disulfonamide、saccharin-o-toluenesulfonamide、saccharin-6-sulfonamide、N-methyl-o-toluene-sulfonamide、methyl-o-chlorobenzoate、4、4'-dibenzoylsulfone、2- or 3-carboxy thiaxanthone-5-dioxide、o-sulfobenzamide、methyl-o-sulfamoylbenzoate、methyl-N-methylsulfamoylbenzoate、saccharin-o-toluenesulfoxylimide、& other、Reported impurities in saccharin & sodium saccharin、Formulations、Preparations: Grades: Commercial、CP、Chemically pure: A grade designation signifying a minimum of impurities、but not 100% pure、USP、United States Pharmacopeia、FCC、Food Chemicals Codex、.、Sodium saccharin FCC (Food Chemicals Codex) is available in the USA in four grades: spray-dried、containing 3.0% moisture、powder、containing 5.0-5.8% moisture、pelletized、containing 10.5-11.5% moisture、and granular、containing 14.0-15.0% moisture.
