Features Of BASF Lutensol XA 40 Surfactants

  1. Nonionic surfactant based on linear alcohol ethoxylate with optimized hydrophilic-lipophilic balance (HLB ≈ 13.5) for broad compatibility.

  2. Excellent emulsification and solubilization performance in aqueous systems across varying pH and electrolyte concentrations.

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

  4. Good biodegradability (OECD 301E compliant) and favorable toxicological profile for sustainable formulation design.

  5. Thermally stable up to 80 °C and compatible with common anionic, cationic, and amphoteric surfactants.

Typical Applications Of BASF Lutensol XA 40 Surfactants

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

  2. Metalworking fluids—especially semi-synthetic and soluble oil concentrates requiring stable emulsion and corrosion inhibition support.

  3. Agrochemical adjuvants for enhancing active ingredient dispersion and foliar uptake in aqueous spray solutions.

  4. Textile auxiliaries such as scouring and dyeing assistants where low foam and high wetting efficiency are critical.

  5. Paint and coating additives for pigment wetting, dispersion stabilization, and viscosity control in waterborne systems.
