I worked for a perfumery and the oil is the more potent of the two. The oils react with your skin's oil. The eau de toilette has a less concentrated amount of fragrance in the productWhich one stays longer; perfume oil or eau de toilette?
Oil
The attar strength of perfume oil is higher than eau de toilette. Thereafter the concentration diminishes with cologne, and in the case of men's toiletries, after shave.


With perfume oil, a mere drop will have the same effect as a spray of cologne.


.....and you don't want to know where they get some of the scents from.
They both stay but I think the perfume oil is more concentrated. The reason the smell seems to dissipate is because the nerve (olfactory) in your nose that actually does the smelling for you gets accustomed to a smell and raises its threshold to it. Which means the wearer of the perfume can no longer smell it, so this person puts on more and more and more. Unfortunately what the wearer doesn't realize is that everyone else can smell it without any difficulty. When they keep putting it on because they can't smell it anymore, they may think they smell pretty good, but everyone else is choking on the stench. I've known Cologne wearers whose stench was left behind in the air up to 10 hours after they left a room!
the perfume oil. the oil also produces a thicker, more potent fragrance. if you don't want to smell too heavy i would stick with the eau de toilette.
perfume!!
