Wikipedia says sodium percarbonate is "a laboratory source of anhydrous
hydrogen peroxide" so there must be some way to get it out without
decomposing it, maybe not by dissolving it in water. Might not be
practical for rocket quantities though.

It's very unlikely you would ever get a great deal of peroxide from it as
when water is added the PH of the solution becomes alkaline which allows
the peroxide to disassociate very quickly on most any organic material. The
possible way around this would be to add it to a acidic based water to get
the PH below 6. However you still have major contaminates to reduce out
before you would even attempt to concentrate this. Being restricted to12%
aqueous H2O2 In the UK is going to make it tough for you to get any
reasonable amount of rocket grade peroxide

Greetings,
Sodium Carbonate Peroxide is sold in the UK (and most likely in other
teritories too) as "Vanish" laundry detergent. It can also be had at low
cost from chemical suppliers.
Apparently it is about 27-30% H2O2. Does anyone know the alchemy required
to extract the H2O2? I have read various conflicting accounts of how to do
it.
