This is the #1 used diaper rash cream for babies for a reason. The main ingredient is
Zinc Oxide, at 40%, which is a skin protectant, and also works for deodorizing and even is antibacterial. If you want to avoid the fragrance that Desitin has, you may be able to just buy zinc oxide powder online (used by people that make their own lotions and sunscreens), but I have not tried this.
