Hi there, I'm making home-made diaper rash ointment with coconut oil, zinc oxide (25%), beeswax, and 5% v/v vitamin e. Is the amount of vitamin e safe for topical use on infants?

Diaper rash. Vitamin E is pretty benign for infants. If you are using it tpically in a butt paste if should be pretty safe to use topically several times a day for even a week or more. It is a great treatment for rashes and scars.
