Description

Fatty Acids, Tall-Oil, Ammonium Salts CAS NO 68132-50-3 is an ammonium salt derivative of tall oil fatty acids, a versatile class of surfactants and emulsifiers. This compound is valued for its excellent emulsifying, dispersing, and surface-active properties in aqueous systems. It is a critical raw material for formulators in the agrochemical, coatings, and industrial cleaning sectors seeking effective, anionic-active components.

Application

• Agrochemical Formulations: Acts as a key emulsifier and dispersant in the production of emulsifiable concentrates (ECs) and suspension concentrates (SCs) for pesticides and herbicides.
• Coatings and Inks: Used as a grinding aid, pigment dispersant, and stabilizer in water-based paints, coatings, and printing inks to improve color development and shelf stability.
• Industrial & Institutional Cleaners: Serves as a primary surfactant and emulsifier in heavy-duty degreasers, metal cleaners, and floor care products.
• Asphalt Emulsions: Functions as an emulsifying agent in cationic asphalt emulsions used for road construction and maintenance.
• Textile Processing: Employed as a lubricant, softener, and antistatic agent in fiber processing and finishing operations.
• Metalworking Fluids: Utilized as an emulsifier and corrosion inhibitor in soluble oil and semi-synthetic metalworking fluids.
