regular, non-organic Perfumers alcohol can be had at Remet, in Los Angeles, tell them I sent you. I just spoke to the VP at a trade show this week.
Someone else may knopw where to get the Organic, but I think it's in the Pacific Nothwest.
Use the Perfumers Search, made by Mark Evans who mentioned it above to find EO's from good suppliers.
But in the USA in general: Liberty Naturals, Eden Botanicals, White Lotus Aromatics, Floracopeia, Appalachian Valley natural products, Nemat International, Camden Grey, Perfumers Apprentice, essentialoils.com, essential7.com, those are the most accessible, with online sales and information. Then there's also higher volume dealers like Prima Fleur, Essential Oil University, and others around. Most often we stay away from New Directions, worldwide, their reputation has been impuned, they're a supplier of last resort. IN UK, Hermitage is very good. Other UK people will have to fill in other suppliers of repute.
Bestbottles, www.bottlesetc.com/ in Los Angeles, Nemat, these are all bottles suppliers.
