Features Of BASF Lutensol TO 129 Surfactants

  1. Nonionic surfactant based on linear alcohol ethoxylate chemistry with optimized hydrophile-lipophile balance (HLB ≈ 13.5).

  2. Excellent wetting, emulsifying, and solubilizing performance in both hard and soft water.

  3. Good low-temperature stability and resistance to electrolytes, supporting robust formulation performance.

  4. Biodegradable under aerobic conditions, aligned with EU Ecolabel and OECD 301 series testing guidelines.

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

Typical Applications Of BASF Lutensol TO 129 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 residue control.

  3. Agrochemical adjuvants for enhancing active ingredient dispersion and foliar uptake.

  4. Textile auxiliaries such as scouring and dyeing assistants in cotton and polyester processing.

  5. Paint and coating additives for pigment wetting, defoaming synergy, and viscosity stabilization.
