BASF Tetronic 701 Surfactant

BASF Tetronic 701 Surfactant is a nonionic, thermoresponsive triblock copolymer (PEO–PPO–PEO) from BASF’s Tetronic® series. It functions as an effective solubilizer, emulsifier, and viscosity modifier in agrochemicals, pharmaceuticals, and personal care formulations. Its unique reverse thermal gelation behavior enables controlled release and enhanced formulation stability across varying temperatures.

Features Of BASF Tetronic 701 Surfactant

  1. Pluronic®-type triblock copolymer (PEO–PPO–PEO) with high hydrophilic-lipophilic balance (HLB ≈ 18–20).

  2. Excellent solubilizing and emulsifying capacity for hydrophobic actives in aqueous systems.

  3. Non-ionic, low-foaming, and compatible with electrolytes, acids, and bases across broad pH range.

  4. Thermally responsive—exhibits reversible micellization and gelation behavior near physiological temperatures.

  5. EU REACH registered and compliant with ISO 9001 manufacturing standards.

Typical Applications Of BASF Tetronic 701 Surfactant

  1. Topical pharmaceutical formulations (e.g., gels, creams, and transdermal delivery systems).

  2. Personal care products requiring mild, non-irritating solubilizers (e.g., micellar cleansers, serums).

  3. Agrochemical adjuvants for enhancing foliar uptake of active ingredients.

  4. Industrial cleaning formulations targeting oily soils in low-temperature processes.

  5. Biotechnology applications including protein stabilization and cell culture media supplementation.
