BASF Lutensol ON 79 Surfactants

BASF Lutensol ON 79 is a nonionic surfactant from BASF’s Lutensol ON series, featuring high ethoxylation (EO~79) for exceptional solubilization and low-foaming detergency in industrial cleaners, agrochemicals, and textile auxiliaries. It offers excellent wetting, emulsification, and temperature stability with low cloud point behavior.

Features Of BASF Lutensol ON 79 Surfactants

  1. Nonionic ethoxylated alkylphenol surfactant with balanced hydrophilic-lipophilic properties.

  2. Excellent wetting, emulsifying, and dispersing performance in aqueous systems.

  3. Good compatibility with anionic, cationic, and other nonionic surfactants.

  4. Stable across a broad pH range (pH 4–12) and tolerant to moderate electrolyte concentrations.

  5. Low foaming profile suitable for high-shear industrial cleaning and formulation processes.

Typical Applications Of BASF Lutensol ON 79 Surfactants

  1. Industrial and institutional cleaners (I&I), including hard-surface degreasers and floor cleaners.

  2. Agrochemical formulations—used as emulsifier and solubilizer in EC (emulsifiable concentrate) and SC (suspension concentrate) products.

  3. Textile auxiliaries, especially for scouring, dye leveling, and pigment dispersion.

  4. Metalworking fluids, where stable oil-in-water emulsions and corrosion inhibition support are required.

  5. Paints and coatings—functions as a co-emulsifier and stabilizer in acrylic and styrene-butadiene latex systems.
