Hydroxy Stearic Acid (12 HAS)
Hydroxy Stearic Acid (12 HAS)
Standard-grade 12-HSA is a saturated fatty acid produced by hydrogenating castor oil, which is naturally derived from castor beans. The oil’s double bonds are saturated as a result of hydrogenation, producing stearic acid. Manufacturers perform the process at room temperature using pressure and an alcohol solvent.

What is 12-Hydroxy Stearic Acid (12-HSA)?
12-HSA is a saturated, hydroxylated fatty acid derived from hydrogenated castor oil. It appears as a white, waxy solid and is widely used in lubricants, cosmetics, and industrial formulations for its thickening and structuring properties.
What are the key applications of 12-HSA?
It is commonly used in the production of lithium and calcium greases, PVC stabilizers, cosmetics, coatings, and as a gelling agent in various formulations. Its ability to form soaps and gels makes it essential in many high-performance products.
What makes 12-HSA different from regular stearic acid?
Unlike standard stearic acid, 12-HSA has a hydroxyl (-OH) group at the 12th carbon position. This gives it better lubricity, solubility characteristics, and compatibility in complex formulations, especially in greases and personal care products.
Is 12-HSA safe for cosmetic or pharmaceutical use?
Yes, 12-HSA is considered safe and is used in creams, ointments, and emulsions as a co-emulsifier, thickener, and texture enhancer. Its high purity grade variants are suitable for regulated personal care and pharmaceutical applications.
Is 12-Hydroxy Stearic Acid biodegradable and sustainable?
Yes. Since it is derived from hydrogenated castor oil—a renewable and plant-based source—12-HSA is biodegradable and environmentally friendly, supporting greener formulations.
