Description

2-Hydroxystearic Acid Methyl Ester is a fatty acid ester derivative of stearic acid, valued for its bifunctional nature as a lubricant and chemical intermediate. This compound is particularly significant for its ability to modify surface properties and reduce friction in demanding formulations. It is essential for manufacturers in the lubricants, plastics, and personal care industries seeking performance additives.

Application

• As a lubricant and mold release agent in polymer processing and plastic manufacturing.
• As a key chemical intermediate for synthesizing more complex surfactants and esters.
• As a viscosity modifier and flow improver in industrial lubricants and greases.
• As a softening and conditioning agent in cosmetic and personal care formulations.
• As a corrosion inhibitor component in metalworking fluids and protective coatings.
• As a textile auxiliaries for fiber lubrication and finishing.
