Features Of BASF Lutensol TO 5 Surfactants

  1. Nonionic surfactant based on linear alcohol ethoxylate (C13–C15) with optimized hydrophilic-lipophilic balance (HLB ≈ 5).

  2. Excellent emulsifying and solubilizing performance in oil-in-water systems, particularly effective at low temperatures.

  3. Low foaming profile suitable for industrial cleaning and metalworking fluid formulations requiring controlled foam generation.

  4. Good biodegradability and favorable ecotoxicological profile in accordance with OECD 301 series testing guidelines.

  5. Stable across a broad pH range (pH 4–12), enabling compatibility with acidic, neutral, and alkaline formulations.

Typical Applications Of BASF Lutensol TO 5 Surfactants

  1. Metalworking fluids — as an emulsifier and stabilizer in soluble oil concentrates.

  2. Industrial cleaners — for heavy-duty degreasing of machinery, parts, and equipment.

  3. Agrochemical formulations — as a co-emulsifier in EC (emulsifiable concentrate) and SE (soluble emulsion) products.

  4. Textile auxiliaries — for scouring and desizing bath stabilization in cotton processing.

  5. Paints and coatings — as a wetting and dispersing aid in pigment grinding and low-VOC architectural formulations.
