Aluminum Hydroxide Gel and Dried Aluminum Hydroxide
Aluminum Hydroxide Gel USP Grade:
Al(OH)3 --- 78.00 --- CAS 21645-51-2
Aluminum Hydroxide Gel is a suspension of amorphous aluminum hydroxide in which there is a partial substitution of carbonate for hydroxide. It contains the equivalent of not less than 90.0 percent and not more than 110.0 percent of the labeled amount of aluminum hydroxide [Al(OH)3]. It may contain Peppermint Oil, Glycerin, Sorbitol, Sucrose, Saccharin, or other suitable flavors, and it may contain suitable antimicrobial agents.
Identification:
A: Place about 1 g in a flask equipped with a stopper and glass tubing, the tip of which is immersed in calcium hydroxide in a test tube. Add 5 mL of 3 N hydrochloric acid to the flask, and immediately insert the stopper: gas evolves in the flask and a precipitate is formed in the test tube.
B: The solution remaining in the flask responds to the tests for Aluminum.
Microbial limits: Its total aerobic microbial count does not exceed 100 cfu per mL, and it meets the requirements of the test for the absence of Escherichia coli.
Acid-neutralizing capacity: Not less than 65.0% of the expected mEq value, calculated from the results of the Assay, is obtained. Each mg of Al(OH)3 has an expected acid-neutralizing capacity value of 0.0385 mEq.
pH: between 5.5 and 8.0, determined potentiometrically.
Chloride: Transfer an accurately measured quantity of the Gel, equivalent to 0.6 g of Al(OH)3, to a porcelain dish. Add 0.1 mL of potassium chromate and 25 mL of water. Stir, and add 0.10 N silver nitrate until a faint, persistent pink color is obtained: not more than 8.0 mL of 0.10 N silver nitrate is required [4.7%, based on the Al(OH)3 content].
Sulfate: Add 5.0 mL of 3 N hydrochloric acid to an accurately measured quantity of the Gel, equivalent to 0.3 g of Al(OH)3, and heat to dissolve the specimen under test. Cool, dilute with water to 250 mL, and filter if necessary: a 20-mL portion of the filtrate shows no more sulfate than corresponds to 0.20 mL of 0.020 N sulfuric acid [0.8%, based on the Al(OH)3 content].
Arsenic: --- The limit is 0.001%, based on the Al(OH)3 content.
Heavy metals: Dissolve an accurately measured quantity of the Gel, equivalent to 0.24 g of Al(OH)3, in 10 mL of 3 N hydrochloric acid with the aid of heat, filter, if necessary, and dilute with water to 25 mL: the limit is 0.0083%, based on the Al(OH)3 content.
