Description

Fatty Acids, Tallow, Sesquiesters With Polyethylene Glycol CAS NO 61791-06-8 is a non-ionic surfactant derived from natural tallow fatty acids and polyethylene glycol, creating a versatile chemical intermediate. This compound is valued for its excellent emulsifying, dispersing, and lubricating properties, making it a key functional ingredient in numerous industrial formulations. It is primarily sought after by manufacturers in the personal care, textile processing, metalworking, and agrochemical industries for its ability to improve product performance and process efficiency.

Application

• Personal Care & Cosmetics: Acts as an emulsifier, opacifier, and pearlizing agent in creams, lotions, shampoos, and liquid soaps.
• Textile Processing: Used as a lubricant, softener, and antistatic agent in fiber spinning and fabric finishing.
• Metalworking Fluids: Serves as an emulsifier and corrosion inhibitor in soluble oils and coolants.
• Agrochemicals: Functions as an adjuvant and emulsifier in pesticide and herbicide formulations to enhance spreading and adhesion.
• Industrial Cleaning: Employed as a surfactant and degreaser in heavy-duty cleaning products and institutional cleaners.
• Plastics & Polymers: Used as an internal and external lubricant and antistatic agent in polymer processing.
• Leather Processing: Acts as a fatliquoring agent to soften and condition leather.
• Paper & Pulp Industry: Utilized as a defoamer and dispersant in paper coating and pulp processing.
