Features Of BASF Lutensol FA 15T Surfactants

  1. Nonionic surfactant based on fatty alcohol ethoxylate with optimized hydrophilic-lipophilic balance (HLB ≈ 15.0) for superior emulsification and solubilization.

  2. Excellent low-temperature stability and clarity in aqueous formulations, enabling year-round formulation flexibility.

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

  4. Biodegradable under OECD 301 standard, supporting sustainable product stewardship and regulatory compliance.

  5. Compatible with electrolytes, acids, and common co-surfactants, enhancing formulation robustness in complex systems.

Typical Applications Of BASF Lutensol FA 15T Surfactants

  1. Industrial and institutional (I&I) hard-surface cleaners, including alkaline degreasers and sanitizing solutions.

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

  3. Agrochemical adjuvants for improving active ingredient dispersion and foliar retention.

  4. Textile auxiliaries such as dyeing assistants and leveling agents in polyester and blended fabric processing.

  5. Paint and coating additives for pigment wetting, defoaming support, and rheology control in waterborne systems.
