Ethoxylated tall oil fatty acids

Ethoxylated tall oil fatty acids (CAS 61791-00-2) are nonionic surfactants derived from tall oil through ethoxylation. Also marketed as Ninox AOO.

Where is Ethoxylated tall oil fatty acids used?

• Textile and leather processing: fiber lubricants and softening agents
• Scouring components that improve substrate wettability and dye uptake uniformity
• Industrial and institutional cleaners: emulsifiers and degreasing actives in hard surface and metal cleaning formulations
• Agrochemicals: emulsifiers and spreading agents in herbicide, fungicide, and insecticide concentrates
• Coatings and adhesives: stabilize pigment dispersions and improve substrate wetting on difficult surfaces
• The HLB value varies with the degree of ethoxylation, allowing formulators to select grades matched to specific application requirements.

Good to know: Grades are differentiated primarily by ethylene oxide chain length: low-EO variants favor oil-soluble applications, while higher-EO grades offer water dispersibility for aqueous systems.
