PROBLEM TO BE SOLVED: To provide an endotoxin remover for biological matter.SOLUTION: The endotoxin remover for biological matter is provided that contains a compound represented by general formula (1) and/or a compound represented by general formula (2) and water. The biological matter is at least one selected from the group consisting of a saccharide, a protein and a nucleic acid [in formula (1) or formula (2), A1O-60 independently represent a C2-3 alkyleneoxy group, m1-6 is an average number of added moles of A1O-60, m1,4 is a number of 1-100 and m2,3,5,6 is a number of 0-100. R1 independently represents H, an OH group, an alkyl group, an alkyl ether group or an acyloxy group, R2 independently represents water H, an alkyl group, an alkyl ether group or an acyloxy group, R3 is an alkyl group or an acyl group].SELECTED DRAWING: NoneCOPYRIGHT: (C)2018,JPO&INPIT【課題】生体物質用エンドトキシン除去剤の提供。【解決手段】一般式（１）で表される化合物及び／又は下記一般式（２）で表される化合物と水とを含む生体物質用エンドトキシン除去剤であって、生体物質が糖類、タンパク質及び核酸からなる群か選ばれる少なくとも１種である生体物質用エンドトキシン除去剤。［式（１）又は式（２）中、Ａ１Ｏ～６０はそれぞれ独立にＣ２～３のアルキレンオキシ基を表し、ｍ１～６は、Ａ１Ｏ～６０の平均付加モル数を表し、ｍ１，４は１～１００、ｍ２，３，５，６は０～１００の数である。Ｒ１は、それぞれ独立にＨ、ＯＨ基、アルキル基、アルキルエーテル基又はアシルオキシ基を表し、Ｒ２は、それぞれ独立に水Ｈ、アルキル基、アルキルエーテル基又はアシルオキシ基を表し、Ｒ３はアルキル基又はアシル基を表す。］【選択図】なし
