Castor Oil USP NF
Castor Oil is the fixed oil obtained from the seed of Ricinus communis Linné (Fam. Euphorbiaceae). It contains no added substances.
Specific gravity: between 0.957 and 0.961.
Distinction from most other fixed oils: It is only partly soluble in solvent hexane (distinction from most other fixed oils), but it yields a clear liquid with an equal volume of alcohol (foreign fixed oils).
Heavy metals: 0.001%.
Free fatty acids: The free fatty acids in 10 g require for neutralization not more than 3.5 mL of 0.10 N sodium hydroxide.
Hydroxyl value: To pass the test. The hydroxyl value is between 160 and 168.
Iodine value: between 83 and 88.
Saponification value: between 176 and 182.
Castor Oil FCC Food Grade
Ricinus Oil
INS: 1503 CAS: [8001-79-4]
DESCRIPTION
Castor Oil occurs as a pale yellow or almost colorless, transparent, viscous liquid. It is the fixed oil obtained from the seed of Ricinus communis L. (Fam. Euphorbiaceae) and consists mainly of the triglyceride of ricinoleic acid. It is soluble in alcohol, and is miscible with absolute alcohol, with glacial acetic acid, with chloroform, and with ether.
Function: Anti-sticking agent; release agent; component of protective coatings.
