Description
12-Hydroxystearic acid (CAS 106-14-9) is a hydroxylated fatty acid derived from castor oil, commercially available under trade names including Harwax A, Ceroxin GL, Loxiol G 21, Barolub FTO, and Cerit FAC 3. It carries no assigned E-code and is classified under HS code 29181990.
In personal care formulations, it functions as an emulsion stabilizer and emollient by anchoring at oil-water interfaces and modifying rheology through hydrogen-bonded gel networks. In lubricant and metalworking applications, it serves as a base material for lithium and calcium greases, where its hydroxyl group enables soap formation and controls thickener structure.
The material is supplied as powder or flakes in industrial and cosmetic grades, with compliance documentation available for REACH registration. Packaging typically ranges from 25 kg bags to bulk quantities. Suppliers should confirm grade suitability against Ph.Eur. or FCC specifications depending on the intended application.
