What each registry publishes about 2-nonenoic acid gamma-lactone.
Every row comes from a published regulator source, linked so you can read it yourself. "Prohibited" means a regulator has affirmatively banned it; "not authorized" means it has never been cleared for that use there. The two are not the same thing, so we never collapse them.
