I have the same sort of sensitivities to scented products in general, some of which really irritate my sinuses. Scented baby oil, for example, when I've tried that for sharpening purposes on oil stones. That smell lingers in my sinuses for hours after I've finished and cleaned up. I used to use dryer sheets, many years ago, until one day I actually developed a rash with BLISTERS, directly underneath the collar of a shirt that'd been laundered with them. Before the rash & blisters developed, I'd frequently noticed some itchiness under the collar of that shirt and other clothing, where it contacted my skin. I think, in that one case, it was a combination of the scented additive in the dryer sheets, a polyester shirt (eventually ditched those, too) and a very hot day that had me sweating a lot. I never had that problem again, after ditching the dryer sheets and any other type of scented fabric softeners in my laundry.
With Goo Gone, it's more about a lingering petroleum-ish odor of it's base solvent that I also notice from products like (so-called) 'odorless' mineral spirits, which is NOT odorless, but maybe just less foul-smelling than other types. I've tried using that before, for cleaning wood and such; but then the wood STINKS of the stuff for a couple or three days afterward. The Goo Gone odor isn't as persistent as from the mineral spirits, and it cleans up fairly easily by washing the hands. So, I can live with it.
I think Goo Gone's added citrus-based element may add some light scent. But for the most part, I don't think that's what bothers me, surprisingly.
