This could be one of the reasons, yeah. I can't remember smelling anything other than aquatic "cologne" on male persons my age. But they don't apply lightly. At all. Which pretty much contradicts the old reasoning of wearing EdC. So, to my understanding, a higher concentration doesn't go hand in hand with more projection, because the evaporating alcohol supports the sillage. At least that's what I've read multiple times on BN. So to say, an EdC should have a rather big projection, but given its lighter nature of aromatics, it doesn't seem extreme. Likewise, an éxtrait de parfum doesn't project more than an EdP -- it probably actually stays closer to the skin --, but the smell is more rich and concentrated (obviously depends on the nature of the parfum). But then again, if I was to smear a little alcohol on my skin, it would evaporate (and support the release of "smell") in a manner of seconds -- it would hardly last minutes -- so I'm not sure whether it really affects the projection itself (other than the short timeframe after the initial spray) and therefore I have doubts that the former reasoning is correct. Another point: you sometimes smell the evaporating alcohol for a short time after you've applied EdC. Can anyone comment on this? Is it really as simple as: higher concentration of identical essential oils/synthetics/whatever = more projection, longevity?
