Dear Zakesch,

ILFOSOL 3 does NOT oxidise quickly and we have no issue with any recent batch or any other previous batch come to that.

ILFOSOL 3 has indeed improved oxidising performance than ILFOSOL 2 and ALL develops once opened can ( and do ) deteriorate, but lots of good info posted on APUG on how to properly keep part used chemicals.
