35% food grade hydrogen peroxide...

[Guest guest]

Can anyone tell me whether some 35% food grade h202 that has been stored in a

freezer (in original bottle) is still useable after some six or seven years???

 

Thanks,

 

Nancy

My bottle of 35% H2O2 is about that old, and it's still liquid at deep freeze

temperatures and still able to burn skin. As far as I'm concerned, that means

it's still usable.
