12-Hydroxy Stearic Acid is a creamy colored wax like odorless substance derived from hydrogenation & hydrolysis of Castor Oil & it usually constitutes 83 to 90% of Fatty Acids in Castor Oil. It Presents two reactive functional groups( Carboxyl and hydroxyl on Carbon-12), which allows the production of a large number of chemical derivatives for various applications12-Hydroxy Stearic Acid is the mixed fatty acid obtained by hydrolysis of Hydrogenated Castor Oil with a melt point of approximately 770C
12 Hydroxy Stearic Acid is a saturated C18-Fatty Acid that is a pale Ivory coloured, brittle, hard wax like odourless. It is suitable for its carboxyl and hydroxyl functional groups in various chemical derivatization processes.
It is high melting, brittle, waxy solid at ambient temperatures. It should be stored away from heat to avoid deterioration. It is insoluble in water and it's solubility in many organic warm organic solvents is also limited. Its warmed solution of nonpolar solvent forms mild gel when cooled down. It is a non-toxic, non-hazardous material.
