For most medical products, including those used in first aid, you need to d o studies to determine expiration - or purchase material which has been tes ted and bears an expiration. So if you're using NF PEG400 as a starting mat erial in a presealed container, you could store it through the expiration d ate unless it has been opened. OTOH if you are packaging it, you will like ly need to perform or contract the Sterility Testing of the product, and po ssibly have an FDA and State Board of Pharmacy license to manufacture medic al use materials.
