Features Of BASF Tetronic 304 Surfactant

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

  2. Excellent solubilizing capacity for hydrophobic actives, fragrances, and oils in aqueous systems.

  3. Low cytotoxicity and favorable skin compatibility, supporting mild formulation profiles.

  4. Effective emulsifier and stabilizer across a broad pH range (pH 3–12) without hydrolysis sensitivity.

  5. Biodegradable backbone structure aligned with evolving regulatory and sustainability requirements.

Typical Applications Of BASF Tetronic 304 Surfactant

  1. Personal care: Clear gels, micellar cleansers, and leave-on moisturizers requiring temperature-responsive rheology.

  2. Pharmaceuticals: Solubilization and sustained-release vehicles for poorly water-soluble APIs in topical and ophthalmic formulations.

  3. Agrochemicals: Stabilization of oil-in-water emulsions for EC and SE formulations with low volatility and high dilution stability.

  4. Home care: Fragrance delivery systems and co-surfactant in low-foaming, high-efficiency liquid detergents.

  5. Industrial cleaning: Builder component in alkaline heavy-duty cleaners for metal and surface degreasing.
