I'm making a foot cream using a recipe I've tried before and was thinking of adding peppermint and spearmint essential oils. I never add more than 1% EO in my recipe, but just wanted to find out what the EU maximum limit for these oils are? I really don't want to go over recommended amounts! My internet connection is down again! I'm on my mobile and struggling to search. If anyone could help or point me in the direction of where to search, it would be really appreciated?
