Don't you think it's okay to list like this: base (all of their ingredients in parentheses), shea butter, fragrance.... etc After all, you see it on food products... milk chocolate (list here), granola (list here), etc... I would think anytime you use a ready-made product you count it as one percentage of your total and put that in the appropriate order with the rest of your additives. Sounds reasonable to me, anyway.
