Does Tyre Sealant Go Off?

I've had a bottle of tyre sealant in the shed for a year. Will age or minus degree temperatures make it go off?

If it goes off it goes hard :???:
If it’s still liquid give a good shake to get the bits mixed in again and away you go.

It depends a lot on how warm it gets. I used to have problems with mine in a shed in Scotland in summer where it could get very warm. It would get cooked and go solid after a while.
I ended up keeping it in the house where the temperature was more stable.
The stuff in the bike tyres also deteriorated more quickly than it otherwise would have done.

Well it's still liquid and looked ok so I used it. Front tyres stayed up up rear not sealing yet but I'm sure it will.
