Zusammenfassung:To provide long circulating material free (LCMF) poloxamer compositions and uses thereof, in particular, LCMF poloxamer 188 compositions and uses thereof, and to provide supercritical fluid extraction (SFE) methods and high pressure (subcritical) methods for preparing poloxamer compositions, particularly the LCMF poloxamer compositions.SOLUTION: The LCMF poloxamer 188 is a polyoxyethylene/polyoxypropylene copolymer that has the formula HO(CH2CH2O)a'-[CH(CH3)CH2O]b-(CH2CH2O)aH, wherein: each of a and a' is an integer such that the percentage of (C2H4O) is between 60 to 90 wt.% of the total molecular weight of the copolymer; b is an integer such that the molecular weight of (C3H6O) is between 1,300 and 2,300 Da; 1.5% or less of the total components are low molecular weight components and 1.5% or less of the total components are high molecular weight components; the polydispersity value of the LCMF poloxamer is less than 1.07; and the circulating half-life of the LCMF poloxamer is less than 5.0-fold of the predetermined circulating half-life.SELECTED DRAWING: None 【課題】長期循環物質のない(LCMF)ポロクサマー組成物およびその使用を提供する。特に、LCMFポロクサマー188組成物およびその使用を提供する。ポロクサマー組成物、特にLCMFポロクサマー組成物を調製するための超臨界流体抽出(SFE)法および高圧(亜臨界)法も提供する。【解決手段】HO(CH2CH2O)a'─[CH(CH3)CH2O]b─(CH2CH2O)aHを有するポリオキシエチレン/ポリオキシプロピレンコポリマーであり、a及びa'の各々はC2H4Oのパーセンテージが60〜90重量%となる整数であり、bはC3H6Oの分子量が1,300〜2,300Daとなる整数であり、全成分の1.5%以下が低分子量成分であり且つ全成分の1.5%以下が高分子量成分であり、多分散性値が1.07未満であり、所定の循環半減期の5.0倍以下であるLCMFポロクサマー188。【選択図】なし
