Features Of BASF Lutensol ON 70 Surfactants

  1. Nonionic surfactant based on ethoxylated linear primary alcohols 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 series testing guidelines.

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

Typical Applications Of BASF Lutensol ON 70 Surfactants

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

  2. Agrochemical formulations—particularly as emulsifier in EC (emulsifiable concentrate) and SE (soluble emulsion) products.

  3. Textile auxiliaries for scouring, dye leveling, and dispersion stabilization.

  4. Paints and coatings—used as co-emulsifier and stabilizer in acrylic and styrene-butadiene latex systems.

  5. Household liquid detergents and dishwashing formulations requiring low-foam, high-efficiency surfactancy.
