It contains not less than 98.0 percent and not more than 101.0 percent of CaSO4 i.e. Calcium Sulfate or Calcium Sulphate, calculated on the dried basis. Identification: Dissolve about 200 mg by warming in a mixture of 4 mL of 3 N hydrochloric acid and 16 mL of water. This solution responds to the tests for Calcium and for Sulfate. Loss on drying: Dry it at a temperature not lower than 250 to constant weight: the anhydrous form loses not more than 1.5% of its weight, and the dihydrate loses between 19.0% and 23.0% of its weight. Iron: Dissolve 100 mg in 8 mL of 3 N hydrochloric acid, and dilute with water to 47 mL: the limit is 0.01%. Heavy metals: Mix 2.0 g with 20 mL of water, add 25 mL of 3 N hydrochloric acid, and heat to boiling to dissolve the test specimen. Cool, and add ammonium hydroxide to a pH of 7. Filter, evaporate to a volume of about 25 mL, and re-filter, if necessary, to obtain a clear solution: the limit is 0.001%. Specifications of Calcium Sulphate Dihydrate BP CaSO4-2H2O ... 172.2 Action and use: Excipient. DEFINITION Content: 98.0 per cent to 102.0 per cent of CaSO4,2H2O i.e. Calcium Sulphate Dihydrate or Calcium Sulfate Dihydrate. CHARACTERS Appearance: White or almost white fine powder. Solubility: Very slightly soluble in water, practically insoluble in ethanol (96 per cent). IDENTIFICATION Loss on ignition. Solution S gives reaction of sulphates. Solution S gives reaction of calcium. TESTS Solution S: Dissolve 1.0 g in 50 ml of a 10 per cent V/V solution of hydrochloric acid R by heating at 50C for 5 min. Allow to cool. Acidity or alkalinity: Shake 1.5 g with 15 ml of carbon dioxide-free water for 5 min. Allow to stand for 5 min and filter. To 10 ml of the filtrate add 0.1 ml of phph solution and 0.25 ml of 0.01 M sodium hydroxide. The solution is red. Add 0.30 ml of 0.01 M hydrochloric acid. The solution is colourless. Add 0.2 ml of methyl red solution. The solution is reddish-orange. Chlorides: Maximum 300 ppm. Shake 0.5 g with 15 ml of water R for 5 min. Allow to stand for 15 min and filter. Dilute 5 ml of the filtrate to 15 ml with water. Arsenic: Maximum 10 ppm, determined on 5 ml of solution S. Iron: Maximum 100 ppm. To 0.25 g add a mixture of 5 ml of hydrochloric acid R and 20 ml of water R. Heat to boiling, cool and filter. Heavy metals: Maximum 20 ppm. To 2.5 g add a mixture of 2 ml of hydrochloric acid R and 15 ml of water R. Heat to boiling. Cool and then add 0.5 ml of phph solution R. Cautiously add concentrated ammonia until the colour changes to pink. Add 0.5 ml of glacial acetic acid R and dilute to 25 ml with water R. Filter. 12 ml of the filtrate complies with test A. Prepare the reference solution using lead standard solution (2 ppm Pb. Loss on ignition: 18.0 per cent to 22.0 per cent, determined on 1.000 g by ignition to constant mass at 800 ± 50C. Specifications of Calcium Sulfate FCC Food Grade CaSO4 Formula weight, anhydrous 136.14 CaSO4-2H2O Formula weight, dihydrate 172.18 INS: 516 CAS anhydrous 7778-18-9 CAS dihydrate 10101-41-4 DESCRIPTION Calcium Sulfate occurs as a fine, white to slightly yellow-white powder. It is anhydrous or contains two molecules of water of hydration. Function: Nutrient; yeast food; dough conditioner; firming agent; sequestrant. REQUIREMENTS Identification: Dissolve about 200 mg of sample by warming it with a mixture of 4 mL of 2.7 N hydrochloric acid and 16 mL of water. A white precipitate forms when 5 mL of ammonium oxalate TS is added to 10 mL of the solution. Upon the addition of barium chloride TS to the remaining 10 mL, a white precipitate forms that is insoluble in hydrochloric and nitric acids. Assay: Not less than 98.0% of CaSO4 i.e. Calcium Sulphate, calculated on the dried basis. Fluoride: Not more than 0.003%. Lead: Not more than 2 mg/kg. Loss on Drying Anhydrous: Not more than 1.5%; Dihydrate: Between 19.0% and 23.0%. Selenium: Not more than 0.003%.
