Features Of BASF Tetronic 901 Surfactant

  1. Nonionic, amphiphilic block copolymer based on polyethylene oxide (PEO) and polypropylene oxide (PPO) segments.

  2. Excellent solubilizing and stabilizing capability for hydrophobic actives in aqueous systems.

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

  4. Good compatibility with electrolytes and a broad pH range (pH 3–12).

  5. Biodegradable backbone with low aquatic toxicity, supporting sustainable formulation design.

Typical Applications Of BASF Tetronic 901 Surfactant

  1. Agrochemical formulations — enhancing solubilization and foliar adhesion of active ingredients.

  2. Industrial and institutional (I&I) cleaners — providing grease removal and soil suspension without excessive foam.

  3. Pharmaceutical suspensions and microemulsions — acting as a stabilizer and wetting agent for poorly water-soluble drugs.

  4. Personal care emulsions — enabling stable oil-in-water systems with mild sensory properties.

  5. Coatings and inks — improving pigment dispersion and substrate wetting in water-based systems.
