lowest temp for peroxide storage

[Penners]

Hi fellow geeks,
I have question about the storage of peroxide, I know it shouldn't be kept in a warm/hot temperature but I wonder if it degenerates if kept in too cold a situation? my storage is in our unheated side conservatory and its been very cold this winter. I guess I can do some strand tests to see if its still ok?:irked: they are fairly new bottles of welloxon, I had brought them in but my husband in his infinite wisdom decided to do some rearranging!

I keep all my harsh but stable compatiable chemicals in a lockable cupboard under the sink....its cool and dark there!! hehe!

Your bottles should be fine! Unless it has cracked or has been transfereed to another bottle, or has been in the confirments of lots of heat and oxygen, (ie humidity) then it would cause the hydrogen peroxide to start decompositing its molecular structor. So in simplified matter unless its been kept in a really hot place it would have blown up, keeping it in cool conditions helps keep the peroxide stable. Sorry for my rambling hths xoxo

Mmmmm.... I'm liking the decomposing molecular structure:lol: thanks for your help.:green:

this might seem daft but what about storing them in a cool box ? that way it will stop them getting really cold so they should be safe , you can keep them still locked away but you know theyre environment will be stable , not going warm , cold , freezing etc...

Not a bad idea, but i think it would be too lab like!:lol: The only concern with chemicals like hydrogen peroixde aka H2o2 is that they should be kept in cool conditions, doesnt really affect the chemical if they are in subzero temperatures. In fact it actually increases the shelf life of H2o2.

Its more of a concern if they have a green house effect within say a conservatory or warm store room where it can actually increase the temperature over period of time which is also a contributing factor of degradging the product. The only way of making h2o2 unstable is by seeping bottles and the natural sunlight heating it up. hths xoxo

Decreasing temperatures have little effect on hydrogen peroxide until they drop substantially below 0 degrees C. Crystals do not begin to appear in solutions until -33C (-27.4F) and -52.2C (-62F), respectively. Therefore it's ok to go very cold without any difference to the solution
