Beschreibung
Zusammenfassung:	Polyethylene glycol for use in fields with application to a living body wherein the sum of the contents of ethylene glycol and diethylene glycol in the polyethylene glycol is less than or equal to that expressed in the following formula ÄIÜ: Sum of ethylene glycol and diethylene glycol contents (ppm) = 150x2900x0.85 DIVIDED x wherein x represents the average molecular weight of the polyethylene glycol, and the polyethylene glycol has an average molecular weight ranging from 190 to 1,050.
