What is *that* note in delina exclusif and valaya exclusif??

I recently tried valaya exclusif, and I loved it. It smells like regular valaya + that one note that’s also in delina exclusif. It’s like a powdery, almost vintage smell that’s still airy and fresh. It’s almost creamy? I wish I could describe it better but if you’ve smelled both, you know what I’m talking about. They’re the only PDM fragrances that I’ve smelled that have that note.
