The shelf life of Zinc Oxide Powder is indefinite as long as it is kept away from moisture.

Zinc Oxide Powder will not degrade as long as it is kept dry and stored in a closed container.

I am not sure of the shelf life. I had to stop using it because it hurt my skin (made it feel like it was burning).

I use the product very sparingly so a 1 lb container lasts me a very long time. I have successfully kept it without refrigeration and with no detectable loss in taste or quality for over a year.

The product's shelf life is 2 years. It depends on how long from date of manufacture until you received it. I ordered mine July 2014, and the expiration date is January 2016.

The shelf life is well over a year. This is a product we are going to continue to stock. It does well for us.

Although I've not really paid attention to any labeling' I have kept and used this up to 1yr. without lost of taste or anything. However i do keep it in the refrigerator. I hope this works for you.

It's supposed to last 6 mos in a cool dry pantry or up to a year in the freezer. I haven't been using it long enough to know if this is true.

I may be wrong, but I'm thinking water doesn't go bad. I'm betting the "5 year shelf life" is mostly to get you to buy more in 4 years. :-)Like I said, I could be wrong.

I have kept it for 3 months now without any deterioration. I don't know the maximum shelf life.

The shelf-life for all Purell products is 3 years from the date it was manufactured per Amazon's product description. Hope this helps!

I remeber reading something about its long shelf life. I have a box that has two dates 2006 /2016 so Im thinking its good for 8/10 years. If you have a box your unsure of I would shake it well before use to mix it all up again.

I am not sure of the shelf life exactly,but I can tell you that the previous bottle of clonex that I had before ordering this one lasted about 4 yrs. I used the whole bottle so it might be good for longer than 4 yrs. I never noticed any decrease in the performance, as it always produced pretty well. Some hydro suppliers recommend storing it in the refrigerator, but I never have. I don't use any cloning solution anymore. Go to modularhydro.com to find out why. I don't work for them, just trying to help you out. I bought the $38, 8site cloner and had 8 super healthy rooted clones in 9 days. Never seen anything like it. Check it out.

Well there is a smell to it, but it has a shelf life of about 1.5yrs. Can you see a date anywhere on the bottle? I do not leave mine in direct light either. You could call the manufacturer
