A sterile product is a product free of live microorganisms and will usually undergo terminal sterilization in its final packaging (heat sterilization, steam, gamma radiation, ethylene oxide, etc.).
An aseptic product is a product that cannot be terminally sterilized for various reasons, such as product stability, heat sensitivity or radiation sensitivity.
As a result, such a product should undergo preparation, filling, and sometimes packaging, under conditions that will maintain its sterility.
