There have been a few times when I’ve mentioned using an absolute in some perfume-based conversation, to have the listener tell me later that it was assumed I was talking about tinctures. “Like you were using Absolut vodka or something.”
Aside from my lack of enthusiasm for vodka - not to mention some complications involved with using tinctures1 - there is my tendency to stick with essential oils and direct herbal infusions.
That said, I do still use absolutes although some are environmentally dubious and suppliers aren’t required to tell me what solvent they used to extract the scent. Absolutes aren’t classified as essential oils because of the way they’re extracted: solvent. Yes, these are really what we’re talking about when we speak of solvent-extracted essential oils. They’re not really essential oils, exactly - usually, they’re thicker, stickier, and they evaporate much more slowly. If you left a bottle of jasmine absolute open and a bottle of lemon essential oil, the lemon would disappear into the air much more quickly.2 Not all of them use hexane, which I spoke about before. Some use ethanol, an alcohol solvent based in corn rather than in petroleum.
The theory behind absolute extraction is that it gets out materials that the plant otherwise might not give up - because of delicacy, possibly, since it’s used a lot with florals.
While I would certainly prefer my absolutes to be extracted with ethanol over hexane, it’s not an ideal situation and given time and adequate space I will probably replace everything with C02 extracts or resort to enfleurage.
