Has anyone here done a pure peppermint oil soap? I recently did a peppermint 2nd distill EO soap at 2.5%. It feels nice on my skin, nice and cooling, smells absolutely wonderful too (strong scent), but I'm kind of wondering if this was too much. Brambleberry's fragrance calculator told me up to 3% was fine but now I'm looking at a few other resources for other scents and noticed a few times that peppermint EO max is listed at 2% of the total weight. I don't have sensitive skin at all and figured I'd put a bit more in vs. less in case it faded. Curious about others experiences. I'm hoping to give it out as gifts, might have my husband and mom test it and see if it's irritating before I give it out on a larger scale. Anyone done it at this percentage without any adverse effects? Thank you!
