DESCRIPTION

Aluminum Monostearate USP NF Grade
Aluminum, dihydroxy(octadecanoato-O-)-.
Dihydroxy(stearato)aluminum --- CAS Number 7047-84-9.
Aluminum Monostearate is a compound of aluminum with a mixture of solid organic acids obtained from fats and consists chiefly of variable proportions of aluminum monostearate and aluminum monopalmitate. It contains the equivalent of not less than 14.5 percent and not more than 16.5 percent of Al2O3, calculated on the dried basis.

Packaging and storage: Preserve in well-closed containers.
Identification:
A: Heat 1 g with a mixture of 25 mL of water and 5 mL of hydrochloric acid for 1 hour, replacing the water as it evaporates: fatty acids are liberated, floating as an oily layer on the surface of the liquid, and the water layer responds to the tests for.
B: Mix intimately 25 g with 100 mL of ether in a 500-mL flask, add 150 mL of 3 N hydrochloric acid, attach a water-cooled condenser, and heat on a steam bath under reflux for 15 minutes. Cool, and transfer both layers to a separator with the aid of an additional 100 mL of ether. Shake vigorously and allow the layers to separate. Remove the water layer and wash the ether layer with three 30 mL portions of water. Transfer the ether layer to a small beaker, warm on a steam bath until the ether has evaporated and the fatty acids are clear, and dry the acids at 105 for 20 minutes: the solidification temperature of the fatty acids is not below 54C.
Loss on drying: Dry it at 80C for 16 hours: it loses not more than 2.0% of its weight.
Arsenic: -- The limit is 4 ppm.
Heavy metals: -- The limit is 50 micro-gm per g.
Assay: Accurately weigh 5 g of Aluminum Monostearate in a covered platinum crucible that previously has been ignited for 20 minutes, cooled over anhydrous magnesium perchlorate, and weighed. Heat the open crucible gently, without allowing the specimen to burst into flame and gradually increase the heat until the ash is white. Ignite the ash for 20 minutes after the organic matter is removed, and cool. Add 15 mL of water, cover the crucible with a small watch glass, and boil gently for 5 minutes, using a small stirring rod to break up any large lumps of ash. Decant the solution through ash-less filter paper, retaining most of the ash in the crucible. Repeat the extraction with water twice, passing the solutions through the same filter. Transfer the ash to the filter by means of a fine stream of water and wash the crucible and the residue three times with warm water. Transfer the filter paper and the residue to the crucible, dry, and ignite for 20 minutes after the filter paper has burned away. Following the ignition period, cover the crucible, cool over anhydrous magnesium perchlorate for 15 minutes, and weigh the residue of Al2O3 rapidly. Repeat the ignition until constant weight is attained, using 20-minute ignition periods and 15-minute cooling periods. From the weight of the residue remaining in the crucible, calculate the content of Al2O3.
