I've been looking at a lot of the IFRA sheets lately for fragrance oils. I've noticed that the maximum safe usage level on some oils is actually higher for lotions than it is for soap.
For example, I'm looking at one now and Category 4 (which I believe is lotions) is 57.05%, but #9 for this oil is 10.68% (Soap).
Why would it be safer to put more in a product that I plan to leave on vs a product I plan to immediately rinse off?
