Hi hookem,

yes, mixing oil based with alcohol based might give you troubles (there\'s a small section on the Cookbook about this issue) when mixed in an atomizer.

I don\'t really know how DD#1 would behave in an atomizer, but since I mixed my batch of DD#1 in an anonymous rolltop bottle and never had any problem, I suggest you to go that way. 70/30, aka 7:3 ratio of DD#1, is based on mls of respectively SoE and NPA.

Edit: ...but you\'ll probably want to work with drops, eg 7 drops SoE per 3 drops NPA, repeat until you reach desired mix amount [img]/ubbthreads/images/icons/smile.gif[/img]
