Features Of BASF Dehypon LS 531 Surfactant

  1. Nonionic surfactant based on linear alcohol ethoxylate with optimized ethoxylation pattern for balanced hydrophilicity and lipophilicity.

  2. Excellent wetting, emulsifying, and solubilizing performance in hard water and across broad pH ranges (pH 4–12).

  3. Low foaming profile suitable for high-shear and industrial cleaning applications where foam control is critical.

  4. Good compatibility with anionic, cationic, and amphoteric surfactants, enabling versatile formulation flexibility.

  5. Eco-preferred profile: readily biodegradable (OECD 301E compliant) and free of alkylphenol ethoxylates (APEO-free).

Typical Applications Of BASF Dehypon LS 531 Surfactant

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

  2. Automotive care formulations such as pre-wash solutions, wheel cleaners, and engine degreasers.

  3. Agrochemical adjuvants for enhancing pesticide and herbicide spray dispersion and leaf coverage.

  4. Textile processing auxiliaries, particularly in scouring and dyeing baths requiring low-foam wetting agents.

  5. Metalworking fluid additives for improved emulsion stability and boundary lubricity in semi-synthetic coolants.
