Title:
ENDOTOXIN ADSORBENT
Document Type and Number:
WIPO Patent Application WO/2018/139415
Kind Code:
A1
Abstract:
An endotoxin adsorbent, said endotoxin adsorbent comprising crystalline cellulose having a nitrogen atom-containing cationic group, can sufficiently remove endotoxins from a material, from which the endotoxins are to be removed, containing a substance having a cationic group. Also, the endotoxin adsorbent can efficiently remove endotoxins from a highly viscous material. In a typical case, the nitrogen atom-containing cationic group may be a functional group derived from a polyvalent amine and/or a quaternary ammonium salt. In the crystalline cellulose having the nitrogen atom-containing cationic group, the content of the nitrogen atom-containing cationic group may be 0.05-3 meq/dry.g in terms of anion exchange capacity.
