  • Applications

    Chemical name: 9-Octadecenoic acid, 12-hydroxy-, calcium salt (2:1), (9Z,12R)-; CAS number: 6865-33-4 is the calcium salt of ricinoleic acid, a hydroxy fatty acid derived from castor oil. It functions as a thickener, emulsifier, and surfactant in oil–water systems. In cosmetics and personal care, it is commonly used as a thickener and stabilizer for creams and lotions, improving rheology and tactile feel. In industrial lubricants and greases, it acts as a rheology modifier and lubricity additive to enhance film strength and lubricating properties. In coatings, inks, and paints, it can serve as a thickener and rheology modifier to control flow and leveling. In polymer processing, it may be used as a processing aid to adjust viscosity and as a lubricating agent during compounding and extrusion. These applications depend on local regulations and formulation limits.
