Poloxamer

Patent Pending 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 the inventor, Irving Schmolka, who received the patent for these materials in 1973.[2] Poloxamers are also known by the trade names Synperonics,[3] Pluronics,[4] and Kolliphor.
