FO calculator for body butter

[kniquy]

I have been making body butter with essential oils, but now want to venture into using FO in them. The FO I have are brambleberry and I looked into their FO calculator. There is no option for body butter -- is it safe to use a lotion to help figure out the amount of FO. Is this close enough? Is there an actual FO calculator for body butter?

I use the lotion calculator. It's a leave-on product, so same thing, as far as fragrance usage goes. IMO.
