I don't know, but I thought someone should answer you. I got my ambrette seed oil from America--Eden Botanicals. I first tried it, undiluted, one drop on cotton wool last night. I think it's horrible. Nutty, as in peanuts, and a horrible odour perhaps like foot odour. At length, a weak soapy smell, which I suppose is the musk, but the foot odour persists. I am curious what you're planning to do with it? Ambrettolide, on the other hand, is apparently quite pleasant.
