Characteristic

12-Hydroxy Stearic Acid (12-HSA) is a wax-like odourless substance usually used in form of cream-coloured or white flakes or powder. It is derived from Castor Oil (extracted from the seeds of 'Ricinus communis L.") by hydrogenation and hydrolysis. The content of 12-HSA in the fatty acid of hydrogenated Castor oil is about 83-90%.

Application

12-Hydroxy Stearic Acid is widely used in the production of glycerine-free multi-purpose calcium and lithium lubricating greases. Lubricating greases produced out of 12-HSA exhibit excellent resistance to oils and fats, water and solvents and they endue a long-life stability. Besides the application in the lubricating sector, 12-HSA is an important raw material in the production of thixotropic agents for solvent-based coating systems. The production of solvent or waterborne polyesters for paints and the manufacture of wax blends and hot melt adhesives as well as the use as a processing aid for natural and synthetic rubber are further application fields. Another important field is the use of 12-HSA in cosmetics such as deodorants.

Properties  

12-Hydroxy Stearic Acid is a saturated C18-fatty acid. It is suitable for various chemical derivatization due to the carboxyl as well as the hydroxyl functionality. Storage   12-Hydroxy Stearic Acid can be stored at a temperature of + 10 C up to + 30 C under dry conditions for one year.

Safety    

The DIN-Safety data sheet on 12-Hydroxy Stearic Acid informs about all safety relevant data. 12-Hydroxy Stearic Acid is not classified as a hazardous product.  It is an agri commodity cargo.
