Ohhh, now that I re-read it, that makes more sense. If that's the case, then as kandlekrazy said, yes, any candle safe FO can be used in any wax. However, just because it can be used, doesn't necessarily mean it will work well. Almost every scent I've ever used in my paraffin blends have worked great. I don't use soy, but have heard that wax is a little more picky, and not ever scent works great in it. Also, now that I'm heavy into bath and body products, I (usually) only buy skin safe FO's so they can be used in all applications. HTH
