Aluminum Monostearate and Aluminum Distearate
Aluminum monostearate is an organic compound which is a salt of stearic acid and aluminum. It is also referred to as dihydroxy(octadecanoato-O-)aluminum or dihydroxy(stearato)aluminum. It is used to form gels in the packaging of pharmaceuticals, and in the preparation of colors for cosmetics.
Aluminum Monostearate USP NF Grade Specifications:
Aluminum, dihydroxy(octadecanoato-O-)-.
Dihydroxy(stearato)aluminum --- CAS 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.
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.
Aluminum distearate exists as white powder and is an aluminum salt of stearic acid. In the pharmaceutical industry, it is used as an anticaking agent; colorant; emulsion stabilizer; and viscosity increasing agent. According to the FDA, aluminum stearate is considered safe for general or specific, limited use in food.
