Action and use: Excipient.

DEFINITION
Fatty oil obtained by hydrogenation of Virgin Castor oil (0051). It consists mainly of  the triglyceride of 12-hydroxystearic (12-hydroxyoctadecanoic) acid.

CHARACTERS
Appearance: Fine, almost white or pale yellow powder or almost white or pale yellow masses or  flakes.
Solubility: Practically insoluble in water, slightly soluble in methylene chloride, very slightly  soluble in anhydrous ethanol, practically insoluble in light petroleum.

IDENTIFICATION
A. Melting point: 83C to 88C.
B. Hydroxyl value.
C. Composition of fatty acids (see Tests).

TESTS
Acid value: Maximum 4.0, determined on 10.0 g dissolved in 75 mL of hot ethanol (96 per cent).
Hydroxyl value: 145 to 165, determined on a warm solution.
Iodine value: Maximum 5.0.
Alkaline impurities: Dissolve 1.0 g by gentle heating in a mixture of 1.5 mL of ethanol (96 per cent) and  3 mL of toluene. Add 0.05 mL of a 0.4 g/L solution of bromophenol blue in  ethanol  (96) per cent. Not more than 0.2 mL of 0.01 M hydrochloric acid  is required to change the colour of the indicator to yellow.
