Description

Polyethyleneglycol Tall Oil Sesquiester CAS NO 61791-30-8 is a non-ionic surfactant and emulsifier derived from tall oil fatty acids and polyethylene glycol. This versatile chemical intermediate is valued for its excellent emulsifying, dispersing, and lubricating properties in demanding industrial formulations. It is primarily used by manufacturers in the agrochemical, lubricant, metalworking, and textile processing industries seeking effective, stable performance.

Application

• Agrochemical Formulations: Acts as a key emulsifier and dispersant in pesticide and herbicide concentrates, enhancing stability and sprayability.
• Metalworking Fluids: Serves as an emulsifier and lubricity agent in soluble oils and semi-synthetic cutting and grinding fluids.
• Textile Processing: Used as a lubricant, softener, and anti-static agent in fiber spinning and fabric finishing operations.
• Industrial Lubricants & Greases: Functions as an additive to improve the emulsifying and anti-wear characteristics of various lubricant systems.
• Paint & Coating Additives: Employed as a pigment dispersant and grinding aid to improve color development and stability.
• Leather Processing: Utilized as a fatliquoring agent to soften and lubricate leather fibers.
