Features Of BASF Lutensol TO 109 Surfactants

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

  2. Excellent wetting, emulsifying, and solubilizing performance in aqueous systems across a broad pH range.

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

  4. Good biodegradability and favorable ecotoxicological profile consistent with OECD 301 test guidelines.

  5. Stable in hard water and compatible with common anionic, cationic, and amphoteric surfactants.

Typical Applications Of BASF Lutensol TO 109 Surfactants

  1. Industrial and institutional cleaners (I&I), including floor cleaners and degreasers.

  2. Agrochemical formulations, particularly as an emulsifier in EC (emulsifiable concentrate) and SC (suspension concentrate) products.

  3. Textile auxiliaries for scouring, dye leveling, and dispersing agents in dye baths.

  4. Paint and coating additives for pigment wetting and dispersion stabilization.

  5. Home care liquid detergents and dishwashing formulations requiring low-foam, high-rinsability performance.
