Review title is dry rot dropper, my bottle of oil arrived rancid- had to be trashed [SEP] Hopefully the bottle I received was an oversight in aging inventory. My bottle was hard to get open, and once I did I could immediately tell that the oil had oxidized. Totally unusable as it was truly rancid. The oil was thick, all cakds up around the topper, and the bulb dropper was rock hard. I was unable to squeeze it. I think the dropper had dry rotted, then that allowed air into the bottle, leading to a rancid product. It was evident not just based on looks, but also that super special aroma of a rancid oil. Too bad, as I love seed oils for use on body, face, and hair. This had to go directly into garbage. Not at all usable as something with anti-oxidants become PRO-oxidant when exposed to air. This is going to do exactly the opposite of what you want. Again, I give benefit of the doubt. I imagine it was a bad bottle and hopefully not at all what anyone should expect. Even so, I have to rate what I have.
