Octadecanoic acid, 12-hydroxy-, zinc salt (2:1) or Zinc 12-Hydroxy Stearate is the zinc salt of 12-hydroxystearic acid, supplied as a fine white powder. Being mainly used as a thickener and gelling agent in lubricating greases, where it produces excellent mechanical stability and high-temperature resistance. The additional hydroxyl group in Zinc 12-Hydroxy Stearate leads to stronger intermolecular forces and hydrogen bonding. This results in a higher melting point, better gelling ability, and higher viscosity compared to standard zinc stearate. Zinc 12-hydroxystearate also functions as a stabilizer and release agent in plastics, coatings, and printing inks, enhancing water resistance and rheology. Also referred to as (Zinc 12-hydroxystearate & 12-Hydroxystearic acid zinc salt) by Zinc 12-Hydroxy Stearate supplier and manufacturer. We are the leading, trusted Zinc 12-Hydroxy Stearate supplier worldwide and in the United States, with reliable lead times and global supply capability.

The hydroxyl group improves gelling ability and grease performance.
Standard Zinc Stearate is the zinc salt of stearic acid, a saturated fatty acid and Zinc 12-Hydroxy Stearate is the zinc salt of 12-hydroxystearic acid.
While both can function as lubricants, stabilizers, and gelling agents, the superior gelling and thickening properties of the 12-hydroxy version are particularly valued in high-performance greases and cosmetic formulations.
The distinct molecular structure of Zinc 12-Hydroxy Stearate, featuring a hydroxyl group on its fatty acid chain, is key to its functionality in high-performance applications.
Some patents have noted that the unique, porous structure of certain forms of Zinc 12-Hydroxy Stearate allows for the loading of other functional substances, such as catalysts, fragrances, and medicines.
