Features Of BASF Lutensol XL 140 Surfactants

  1. Nonionic surfactant based on ethoxylated linear alcohol with optimized hydrophile-lipophile balance (HLB) for robust emulsification and solubilization.

  2. Excellent low-temperature stability and freeze-thaw resistance, ensuring consistent performance in cold-climate formulations.

  3. Low foaming profile suitable for high-shear industrial cleaning and metalworking applications where foam control is critical.

  4. Good compatibility with electrolytes, acids, and other nonionic and anionic surfactants in complex formulation systems.

  5. EcoVadis-recognized sustainable profile with readily biodegradable backbone and low aquatic toxicity (OECD 301 series compliant).

Typical Applications Of BASF Lutensol XL 140 Surfactants

  1. Industrial and institutional (I&I) hard-surface cleaners, especially alkaline degreasers for food processing equipment.

  2. Metalworking fluids, including soluble oils and semi-synthetic coolants requiring stable oil-in-water emulsions.

  3. Agrochemical adjuvants for improving active ingredient dispersion and foliar retention in crop protection formulations.

  4. Textile auxiliaries such as scouring and dyeing assistants for polyester-cotton blends.

  5. Paint and coating additives for pigment wetting and latex stabilization in architectural and industrial coatings.
