Description

Fatty Acids, C18 And C18-Unsatd., Ethoxylated is a nonionic surfactant derived from the ethoxylation of a blend of stearic (C18 saturated) and oleic/linoleic (C18 unsaturated) fatty acids. This chemical modification imparts excellent emulsifying, dispersing, and wetting properties, making it a versatile intermediate and performance additive. It is essential for formulators in industries such as personal care, textiles, agrochemicals, and industrial cleaning who require stable, mild, and effective surface-active agents.

Application

• Personal Care & Cosmetics: Acts as a primary emulsifier, thickener, and opacifier in creams, lotions, and hair conditioners, providing a rich, stable texture.
• Textile Processing: Used as a lubricant, softener, and antistatic agent in fiber spinning and fabric finishing to improve handle and processing efficiency.
• Agrochemical Formulations: Serves as a key component in pesticide and herbicide emulsions, enhancing spray coverage and active ingredient penetration.
• Industrial & Institutional (I&I) Cleaners: Functions as a degreaser and emulsifier in heavy-duty cleaning products for hard surfaces and machinery.
• Metalworking Fluids: Employed as an emulsifier and corrosion inhibitor in soluble oils and coolants.
• Paints & Coatings: Aids in pigment dispersion and grinding, improving color development and stability in water-based systems.
• Leather Processing: Used in fatliquoring to soften leather and improve its durability and water resistance.
