(I held off asking this question for a while hoping my duh would turn into an 'aha' but it hasn't so I'll deal with the embarrassment of having to admit I don't understand! lol)
UK reg's say soap can have a max of 2% essential oil.
For some reason how to work this out just isn't calculating right in my head!
Firstly I am assuming I only count the oil because the water will evaporate and the lye won't exist in the final product right? So if I have 48oz of oils, does this mean I can use up to 0.97oz of essential oils?
(48+0.97)x0.02 = 0.97oz
If so why does something like Brambleberry's fragrance calculator say 2oz? I know US reg's must be different but my calculations figure I'd have lower than what they classify as a light scent so it just seems wrong?
(I promise I'm not this dense with the rest of my maths, this has just confuzzled me!)
