Bests & Worsts Reviews from Amazon

These oils are not pure essential oils. I smelled some awful chemical undertones when I opened them. All 4 of them had similar undertones, so I decided to perform a paper blot test. On a paper blot test the essential oil should evaporates within 10-15 minutes and when a true essential oil evaporates it leaves no residue, the paper should be completely clean. With the exception of lemon and citrus oils which may leave a slight yellow to orange tint on the paper, but there shouldn't be any oily residue. The results showed that all 4 of these oils were heavily adulterated with some sort of chemical carrier oil. All 4 of them took over an hour to evaporate and all left an oily residue, some more than others. I wouldn't put these on my body or even breathe their fumes in a vaporizer, who knows what kind of chemicals they are adulterated with!
