Narrative:
While operating aircraft X; left seat captain and I detected a 'dirty socks' odor (non-visible) emitting from the conditioned air system. The odor was present from takeoff through level off; and also during the descent through taxi phase. The odor was most intense during the descent phase but varied in strength and seemed to be strongest during large thrust changes. The flight was conducted safely and we arrived to [destination] with no other issues. He notated the issue in the maintenance logbook as suspected aerosolized engine oil in the bleed air system.
