Features Of BASF Tetronic 908 Surfactant

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

  2. Excellent solubilizing capacity for hydrophobic actives in aqueous systems across a broad pH range.

  3. Low cytotoxicity and favorable safety profile, supporting use in personal care and pharmaceutical formulations.

  4. Highly effective emulsifier and stabilizer for oil-in-water and microemulsion systems.

  5. Thermo-responsive viscosity modifier — forms reversible gels upon mild heating, enabling controlled-release applications.

Typical Applications Of BASF Tetronic 908 Surfactant

  1. Topical pharmaceutical gels and dermal delivery systems.

  2. Stabilized microemulsions for active ingredient solubilization in OTC skincare products.

  3. Viscosity-building agent in low-irritancy shampoos and body washes.

  4. Excipient in injectable and ophthalmic formulations requiring non-ionic, low-hemolytic surfactants.

  5. Template or dispersant in nanomaterial synthesis and functional coatings.
