Description

Fatty Acids, C18-Unsatd., Dimers, Ethoxylated is a non-ionic surfactant derived from the ethoxylation of dimerized unsaturated C18 fatty acids. This chemical modification imparts excellent emulsifying, dispersing, and wetting properties, making it a versatile intermediate for demanding formulations. It is primarily sought after by manufacturers in the industrial lubricants, textile processing, agrochemical, and personal care industries for its robust performance and compatibility.

Application

• As a key emulsifier and stabilizer in synthetic metalworking fluids and industrial lubricants.
• As a softening agent, lubricant, and antistatic agent in textile fiber processing and spin finishes.
• As a dispersant and emulsifier in pesticide and herbicide formulations for improved efficacy.
• As a base surfactant for producing specialty esters used in cosmetics and hair care products.
• As a component in concrete release agents and mold release formulations.
• As a processing aid and internal lubricant in polymer and plastic production.
• As a wetting and leveling agent in coatings, inks, and dye preparations.
