Features Of BASF Lutensol A 4N Surfactants

  1. Nonionic alcohol ethoxylate with balanced hydrophilic-lipophilic balance (HLB ≈ 10.5) for versatile performance in diverse formulations.

  2. Excellent wetting and emulsifying properties, especially effective in hard water and across broad pH ranges.

  3. Low foaming profile suitable for industrial cleaning, metalworking, and high-speed processing applications.

  4. Good biodegradability and favorable ecotoxicological profile aligned with EU Ecolabel and OECD 301 screening criteria.

  5. Thermally stable liquid at room temperature with low volatility and minimal odor—ideal for closed-loop and continuous processes.

Typical Applications Of BASF Lutensol A 4N Surfactants

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

  2. Metal cleaning and degreasing formulations for automotive and aerospace pre-treatment lines.

  3. Agrochemical adjuvants enhancing spray droplet spreading and active ingredient uptake on waxy leaf surfaces.

  4. Textile auxiliaries for scouring, dye leveling, and low-foam rinsing in continuous jet dyeing systems.

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