What is Calcium 12-Hydroxystearic Acid?
Calcium 12-Hydroxystearic Acid is a calcium salt of 12-hydroxystearic acid, a fatty acid derived from the hydrogenation of castor oil. The name itself can be broken down into its components: calcium refers to the metal ion, 12-hydroxy points to the hydroxyl group (OH) located at the 12th carbon of the stearic acid chain, and stearic acid is a long-chain fatty acid with 18 carbon atoms.
The compound is often produced as a white, waxy powder or a solid material. It’s primarily used as a stabilizer and lubricant, owing to its chemical structure, which allows it to act as a dispersing agent in various formulations.
