Features Of BASF Lutensol FA 12 Surfactants

  1. Nonionic surfactant based on fatty alcohol ethoxylate (C12) with optimized hydrophilic-lipophilic balance (HLB ≈ 12.5) for balanced emulsification and solubilization.

  2. Excellent low-temperature stability and freeze-thaw resistance, enabling reliable 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 anionic, cationic, and amphoteric surfactants, facilitating versatile formulation design.

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

Typical Applications Of BASF Lutensol FA 12 Surfactants

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

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

  3. Agrochemical adjuvants for enhancing active ingredient dispersion and foliar retention in crop protection sprays.

  4. Textile auxiliaries, particularly in scouring, dye leveling, and low-foam rinsing processes.

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