Description

Octadecanoic Acid, C11-14-Isoalkyl Esters, C13-Rich is a high-purity, branched-chain ester derivative of stearic acid, designed for superior performance in demanding formulations. This specialized ester offers enhanced solubility, thermal stability, and lubricity compared to its linear counterparts, making it a valuable synthetic intermediate and functional additive. It is primarily utilized in the production of high-performance lubricants, plasticizers, and personal care products where consistent quality and reliable supply are critical.

Application

• Synthetic Lubricants & Metalworking Fluids: Acts as a high-performance base oil or additive, providing excellent viscosity-temperature characteristics, lubricity, and oxidation stability.
• Polymer & Plastic Additives: Serves as a specialized plasticizer and processing aid for PVC, rubber, and other polymers, improving flexibility and flow properties.
• Personal Care & Cosmetics: Used as an emollient, thickener, and opacifying agent in creams, lotions, and makeup formulations.
• Industrial Coatings & Inks: Functions as a flow modifier and lubricant, enhancing surface finish and application properties.
• Textile Auxiliaries: Employed as a softening agent and lubricant in fiber processing and finishing.
• Chemical Synthesis: A key intermediate for producing other esters, surfactants, and specialty chemicals.
