Features Of BASF Tetronic 90R4 Surfactant

  1. Non-ionic triblock copolymer based on polypropylene oxide (PPO) and polyethylene oxide (PEO) with unique reverse Pluronic® architecture.

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

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

  4. Good thermal and pH stability across broad formulation conditions (pH 4–10).

  5. Biodegradable backbone and low aquatic toxicity, supporting sustainable formulation goals.

Typical Applications Of BASF Tetronic 90R4 Surfactant

  1. Agrochemical formulations — emulsifiable concentrates (EC) and suspension concentrates (SC).

  2. Industrial and institutional (I&I) cleaners — low-foam alkaline and neutral detergents.

  3. Personal care — solubilizer for fragrances and UV filters in clear gels and aqueous sprays.

  4. Pharmaceutical suspensions and oral liquid dosage forms requiring colloidal stabilization.

  5. Specialty coatings — dispersant and wetting agent for pigment-rich waterborne systems.
