would you expiry date of et.oxid in pakage? i need exp date of et.oxide how many year stablizer in the package?

Ethylene oxide will expire and form polymer chains. You should follow the expiration date of on the container. If there is no expiration date, I would assume the container has a shelf life of 3 months from the day the container is filled. This assumes the container is stored under proper conditions (not exposed to excess heat). Let me know if you need more information.
