This too came from White Lotus Aromatics.  Even though their EOs don’t currently come with GC analysis their oils are high grade, their service is top notch, and I always get a sense that I’m dealing with people of the highest integrity whenever I have dealings with them.

Costus root at 10% dilution. Get ready for this one because the aroma is anything but subtle.

The immediate impression is animalic, wet fur, dirty but not at all unpleasant, deeply natural, slightly fecal and a bit hypnotic, I say this because I just kept sniffing even with the sort of “strange” note, I couldn’t put it down.  I try to stay away from note descriptions that could be negative because the more I hang around perfume ingredients the more I realize that what may smell “bad” as a first impression is only the result of an untrained nose, we’re just not used to smelling it at all or in a certain combination.

1 hour later it still has a very strong presence but has lost its fecal edge and its soooo much more appreciable!

3 hours later it’s not so pungent but remains noticeable, holds together very well, remains integral although it seems more one dimensional now. I definitely like this effect more than that straight out of the bottle.

After 1 day, still strong, maybe even more so now that the alcohol has worn off, much less intrusive and more like a soft caress.

It has a fine tenacity and superb fixative value. Soft, delicate and warm precious woods/orris root odor. Surprising radiant tenacity for an oil which has a fairly low key odor impact. A buttery/fatty note appears shortly after one detects the precious wood/orris root odor. It lends the entire olfactory texture of the oil a very smooth feeling. – White Lotus Aromatics

Keep in mind he’s describing the essential oil and I the CO2, Select.
