Stearic Acid USP Grade Specifications
Octadecanoic acid.
Stearic acid CAS 57-11-4
Stearic Acid is manufactured from fats and oils derived from edible sources and is a mixture of Stearic Acid (C18H36O2) and palmitic acid (C16H32O2). The content of C18H36O2 is not less than 40.0 percent, and the sum of the two is not less than 90.0 percent.
NOTE: Stearic Acid labeled solely for external use is exempt from the requirement that it be prepared from edible sources.
Iodine value: not more than 4.
Residue on ignition: not more than 4 mg, determined on a 4-g portion (0.1%).
Heavy metals: 0.001%.
Mineral acid: Shake 5 g of melted Stearic Acid with an equal volume of hot water for 2 minutes, cool, and filter: the filtrate is not reddened by the addition of 1 drop of methyl orange.
Neutral fat or paraffin: Add 1 g of Stearic Acid to 30 mL of anhydrous sodium carbonate solution (1 in 60) in a flask, and boil the mixture: the resulting solution, while hot, shows not more than a faint opalescence.
Organic volatile impurities: meets the requirements.

DESCRIPTION
Stearic Acid occurs as a hard, white or faintly yellow, somewhat glossy and crystalline solid or as a white or yellowwhite powder. It is a mixture of solid organic acids obtained from fats consisting chiefly of Stearic Acid (C18H36O2) and palmitic acid (C16H32O2). Stearic Acid is practically insoluble in water. One gram dissolves in about 20 mL of alcohol, in 2 mL of chloroform, and in about 3 mL of ether.
REQUIREMENTS
Acid Value: Between 196 and 211.
Iodine Value: Not more than 7.
Lead: Not more than 2 mg/kg.
Residue on Ignition: Not more than 0.1%.
Saponification Value: Between 197 and 212.
Titer (Solidification Point): Between 54.5° and 69°.
Unsaponifiable Matter: Not more than 1.5%.
Water: Not more than 0.2%.
