Yeah, this was actually the first time I've heard of using baby oil for candle wax. Really baby oil is just mineral oil (a petroleum product) with scents added. I was wondering if she was allergic to the scents instead of the oil. If I were going to try a different oil in it's place I'd go with a lighter oil first I think- something similar. I don't use corn oil anymore but isn't it a bit thick? I couldn't find the sapo value to compare so olive oil would just be my first guess- maybe safflower? *shrug*
