BASF Lutensol AO 79 Surfactants

BASF Lutensol AO 79 is a nonionic surfactant from BASF’s Lutensol AO series, featuring ethoxylated linear alcohol chemistry with ~9 EO units. It offers excellent wetting, emulsification, and low-foaming performance in industrial cleaners, agrochemicals, and textile auxiliaries. Highly soluble, biodegradable, and stable in hard water, it ensures consistent formulation efficiency across diverse pH and temperature conditions.

Features Of BASF Lutensol AO 79 Surfactants

  1. Nonionic alcohol ethoxylate with high hydrophilic-lipophilic balance (HLB ≈ 13.5) for excellent water solubility and low-temperature stability.

  2. Outstanding emulsifying and solubilizing performance in aqueous systems, especially for hydrophobic actives and oils.

  3. Low foaming profile suitable for high-shear industrial cleaning and rinse-efficient formulations.

  4. Good compatibility with anionic, cationic, and amphoteric surfactants across broad pH ranges (pH 4–12).

  5. Eco-preferred profile: readily biodegradable (OECD 301B compliant) and free of alkylphenol ethoxylates (APEO-free).

Typical Applications Of BASF Lutensol AO 79 Surfactants

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

  2. Agrochemical formulations — emulsifiable concentrates (EC), suspension concentrates (SC), and microemulsions (ME).

  3. Textile auxiliaries — scouring agents, dye dispersants, and leveling agents for polyester and blends.

  4. Paint and coating additives — pigment wetting, defoaming aid, and co-emulsifier in acrylic and styrene-butadiene dispersions.

  5. Personal care cleansing bases — mild co-surfactant in sulfate-free shampoos and body washes.
