Document Type and Number:
WIPO Patent Application WO/2022/264524
Kind Code:
A1
Abstract:
The present invention provides: an oxidation inhibitor which contains a polyalkylene imine compound as an active ingredient; an oxidation inhibitory activity enhancing agent which contains a polyalkylene imine compound as an active ingredient; an oxidation inhibition method which comprises a process for having a polyalkylene imine compound and an oxidation inhibiting substance coexistent with each other in an oxidation inhibition object; and a method for enhancing oxidation inhibitory activity of an oxidation inhibiting substance, the method comprising a process for having a polyalkylene imine compound and the oxidation inhibiting substance coexistent with each other.
