Important Note: Allantoin is registered as an OTC skin protectant drug with the FDA (Category I; allowed concentration 0.5-2%). This means that if you want to sell a finished product containing allantoin and you make a skin protectant claim (incl. minor cuts, scrapes, burns, chapped skin and lips, poison ivy, poison oak, poison sumac, and insect bites), allantoin must then be listed under 'Active Ingredients' on the label. Also, your facility and your product must be registered with the FDA and you must operate under cGMP guidelines. However, if no skin protectant drug claims are made on the label, allantoin is not considered an OTC drug and no registration is needed.
