"They put a carrier agent in scents..."

Sounds logical to me. It must be what concentrates and amplifies the scent to such a great degree. The natural, delicate aroma of roses gives me no problem. But I have literally gasped for breath when a woman wearing too much of the 'rose oil' perfume has stood next to me. And trust me, I ain't no wimpy/wussy guy getting a case of the 'vapors'...lol. That carrier addition may be the culprit.

a quick google says the carrier agents are typically grape or nut oil, and make up 75% of the fragrence, while the rose oil is 25%.

Which explains that - I am allergic to grapes. Can't even drink wine.

(Whisky is ok...LOL)
