All good points thus far. I'll add in that vanilla is a mainstay in perfumery and often used to sweeten or soften a scent and works as an effective base note, much like sandalwood or musk. Vanilla may often add in a softer, woodsy dimension to scent that may contain loads of spices or extremely earthy notes or accords. But I will admit that I have come across many a scent where I feel that vanilla just throws everything else out the window and ruins its shipmates, or takes over teh character of the scent entirely. But this may have a lot to do with how a scent behaves on one's skin.
Yea I think this when I look on fragrantica and see how often vanilla is listen as an ingredient, but I have never gone on a perfume smelling trip before and found myself complaining about 'all the vanilla' which I think proves that as others have said, when used right, vanilla earns its place in a perfume, at least most of the time.
Vanilla perfumes, vanilla air freshener, vanilla candles, vanilla ice cream, vanilla flavoring for coffee.......the world loves vanilla!
Note vanilla ice cream. it's not that we all might love it at every point in our lives, but who can really say they don't like it? even the pickiest kid will eat vanilla ice cream. I think now that the market seems to be turning the corner on the fresh-to-death scene for males, and slightly more "effeminate" notes are now more acceptable in masculines, vanilla seems like a no brainer, no?
