Poloxamers are nonionic triblock copolymers composed of a central hydrophobic chain of polyoxypropylene (poly (propylene oxide)) flanked by two hydrophilic chains of polyoxyethylene (poly (ethylene oxide)). The word poloxamer was coined by BASF inventor, Irving Schmolka, who received the patent for these materials in 1973. [1]
