Iso E super: dry woody with pleasant ambery subnotes.
Iso-E Super Not as obnoxious as I remembered it from perfumes of previous decades. Big, bright, open, airy, with some of the freshness of aromatic cedar, but sweet and floral, like white flowers and roses. This is Calvin Klein Eternity.
Iso E Super: oh wow it smells exactly like one of the Escentric Molecules fragrances - either Molecule 01 or Escentric 01. I think it might have been the latter but I never remember! Very sweet, watery, slightly fruity woods - although unlike cedarwood and sandalwood.
Iso-E-Super, 2% dilution in carrier oil: this famous molecule packs a punch! Strong and long lasting, but it smells a little...well, like a generic men's fragrance base. Woody, full and rich but...meh. But at least, now I'm curious to smell Escentric Molecules Molecule 01, which is based solely on this aromachemical.
