Features Of BASF Lutensol AO 89 Surfactants

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

  2. Outstanding emulsification and dispersion performance in oil-in-water systems, even with challenging hydrophobic actives.

  3. Low foaming profile suitable for high-shear industrial cleaning and metalworking applications.

  4. Good compatibility with electrolytes, acids, and common co-surfactants in formulated systems.

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

Typical Applications Of BASF Lutensol AO 89 Surfactants

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

  2. Metalworking fluids—used as emulsifier and stabilizer in soluble oil and semi-synthetic coolants.

  3. Agrochemical adjuvants for enhancing the dispersion and foliar uptake of active ingredients.

  4. Textile auxiliaries, particularly in dyeing and printing preparation baths requiring low foam and high wetting.

  5. Paint and coating additives for pigment dispersion and latex stabilization in waterborne systems.
