Non-ionic triblock copolymer based on polypropylene oxide (PPO) and polyethylene oxide (PEO) architecture.
Thermoresponsive behavior with reversible micellization above its cloud point, enabling temperature-triggered solubilization and release.
Excellent surface activity and low foaming characteristics in aqueous systems across broad pH ranges.
High biocompatibility and low cytotoxicity, supporting use in pharmaceutical and personal care formulations.
Good compatibility with electrolytes, surfactants, and active ingredients without significant precipitation or phase separation.
Drug delivery systems, including thermosensitive hydrogels and nanocarriers for controlled release.
Stabilizer in topical and transdermal formulations for enhanced skin permeation and emulsion integrity.
Functional additive in ophthalmic solutions to improve solubilization of poorly water-soluble APIs.
Emulsifier and solubilizer in cosmetic emulsions, especially in “smart” responsive skincare products.
Performance enhancer in industrial cleaning formulations requiring low-foam, high-rinsability surfactancy.
