Aluminum Chlorohydrate consists of complex basic aluminum chloride that is polymeric and loosely hydrated and encompasses a range of aluminum-to-chloride atomic ratios between 1.91:1 and 2.10:1. It contains the equivalent of not less than 90.0 percent and not more than 110.0 percent of the labeled amount of anhydrous aluminum chlorohydrate.

Packaging and storage: Preserve in well-closed containers.
Labeling: The label states the content of anhydrous aluminum chlorohydrate.
Identification: A solution (1 in 10) responds to the tests for Aluminum and for Chloride.
pH: between 3.0 and 5.0, in a solution [15 in 100 (w/w)].
Arsenic: 2 microgm per gm.
Heavy metals: 0.002%.
Limit of iron: To pass the test --- (150 microgm per gm).
Content of aluminum: To pass the test.
Content of chloride: To pass the test.
Aluminum/chloride atomic ratio: Divide the percentage of aluminum found in the test for Content of aluminum by the percentage of chloride found in the test for Content of chloride, and multiply by 35.453/26.98, in which 35.453 and 26.98 are the atomic weights of chlorine and aluminum, respectively: the ratio is between 1.91:1 and 2.10:1.

Aluminum Chlorohydrate Solution USP Grade

Aluminum Chlorohydrate Solution consists of complex basic aluminum chloride that is polymeric and encompasses a range of aluminum-to-chloride ratios between 1.91:1 and 2.10:1. The following solvents may be used: water, propylene glycol, dipropylene glycol, or alcohol. It contains the equivalent of not less than 90.0 percent and not more than 110.0 percent of the labeled concentration of anhydrous aluminum chlorohydrate.

Packaging and storage: Preserve in well-closed containers.
Labeling: Label Solution to state the solvent used and the claimed concentration of anhydrous aluminum chlorohydrate contained therein.

Identification

A: A solution containing the equivalent of about 100 mg of anhydrous aluminum chlorohydrate per mL responds to the tests for Aluminum and for Chloride.
B: Identification of propylene glycol (where stated on the label): Add about 10 mL of isopropyl alcohol to 2 g of Solution, mix, and filter. Evaporate the filtrate to about 1 mL on a steam bath: the IR spectrum of a film of this solution on a silver chloride disk exhibits maxima only at the same wavelengths as that of a similar preparation of a film of propylene glycol.
C: Identification of dipropylene glycol (where stated on the label): Add about 10 mL of isopropyl alcohol to 2 g of Solution, mix, and filter. Evaporate the filtrate to about 1 mL on a steam bath: the IR spectrum of a film of this solution on a silver chloride disk exhibits maxima only at the same wavelengths as that of a similar preparation of a film of dipropylene glycol.
D: Identification of alcohol (where stated on the label): In a small beaker mix 5 drops of Solution with 1 mL of potassium permanganate solution (1 in 100) and 5 drops of 2 N sulfuric acid. Immediately cover the beaker with filter paper moistened with a freshly prepared solution of 0.1 g of sodium nitroferricyanide and 0.25 g of piperazine in 5 mL of water: an intense blue color is produced on the filter paper, the color fading after a few minutes.
pH: between 3.0 and 5.0, in a solution prepared by diluting 3 g of the solution with water to obtain 10 mL.
Arsenic: The limit is 2 ppm.
Heavy metals: The limit is 0.001%.
Limit of iron: To pass the test --- (75 microgm per gm).
Content of aluminum: To pass the test.
Content of chloride: To pass the test.
Aluminum/chloride atomic ratio: Divide the percentage of aluminum found in the test for Content of aluminum by the percentage of chloride found in the test for Content of chloride, and multiply by 35.453/26.98, in which 35.453 and 26.98 are the atomic weights of chlorine and aluminum, respectively: the ratio is between 1.91:1 and 2.10:1.
