Hi Bluereef, I use some Eo's in soy & have had some success with some, less with others. I've had the best results in containers, 4oz tins so far,using EO's at 0.5-0.6 oz per lb wax. Successes so far with patchouli, petitgrain, lavender, geranium & others but I haven't got my notes to hand. I haven't settled on a particular soy cb yet but soy works differently for everyone so I won't recommend anything. You will have to experiment & test like the rest of us but it's fun so enjoy playing & take lots of notes. Sally.
