I bought several essential oils from a company in the UK. Only two of them were great. But those two were extremely great, the sandalwood and vetiver. The other, oh lord! They have this gasoline/turpentine/acetone/solvent type of smell. Worst are the patchouli, Atlas cedarwood and benzoin. And, stupid me, I bought 50ml bottles of each :-(
But I will test them on a coffee filter strip, as some of you wrote, to see if they change from bad to beautiful. If not, I will try to dillute a drop of each in oil, let them sit for a while to breath and see what happens. I do hope they will turn out great after something has evaporated. I would hate to throw them away. If I'm lucky, they smell like something from a garage because they are so concentrated. The patchouli is for sure concentrated, I tried to wear and guess if it was strong! My mother was choking! Vetiver and sandalwood is not that strong, and don't smell used motor oil, so maybe it is a relation between that gasoline smell and strenght of the scent?
But their vetiver is out of this world! I am totally in love with it! It's vetiver from Haiti. It's not earthy, other than the first minutes, but more like a sophisticated men's cologne. But I bought only 10ml of that after reading a very bad review about their vetiver being not from Haiti but something cheap from elswere and stinking. Well, I have no idea, but it is the total opposite of stinking.
I think Atlas cedarwood maybe is the worst. It's like an ashtray filled with gasoline, sat on fire and sprinkled with sawdust and rubber, or something like that. Horrible! But I do hope it can turn into a wood cabin scent. Maybe cold process is the best, so that the lye can eat most of the scent and maybe transform it. But I will not waste soaping oils before I have some clue if it will change into something better or not.
Now you're making me curious, which company?
