Features Of BASF Lutensol TO 65 Surfactants

  1. Nonionic surfactant based on linear alcohol ethoxylate with optimized hydrophilic-lipophilic balance (HLB ≈ 13.5) for balanced emulsification and detergency.

  2. Excellent low-temperature stability and clarity in aqueous solutions, enabling reliable performance in cold-process formulations.

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

  4. Good compatibility with anionic, cationic, and amphoteric surfactants, facilitating versatile formulation design.

  5. Eco-preferred profile with readily biodegradable ethoxylate backbone and no APEO residues, supporting sustainable product stewardship.

Typical Applications Of BASF Lutensol TO 65 Surfactants

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

  2. Metalworking fluids—especially semi-synthetic and soluble oil concentrates requiring stable emulsions and corrosion inhibition.

  3. Agrochemical adjuvants for enhancing spray droplet spreading, retention, and active ingredient uptake.

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

  5. Paint and coating additives for pigment wetting, dispersion stabilization, and gloss enhancement in waterborne systems.
