Interesting comparison case here http://www.ntsb.gov/publictn/2000/HZB0001.htm involving a spill of 2 gallons of 35% hydrogen peroxide in an aircraft cargo hold. After landing, some soaked items nearby were tranferred to another aircraft, and later found smoldering when that aircraft landed. No explosions, despite the fact that large quantities of this stuff, after time for plenty of evaporation-concentration, were lying around airport tarmac while all sorts of activities (including combustion-engine powered vehicles) went on right next to it.

It can be used to make explosive but this stuff is in every beauty salon ranging for 10-40 volume .It’s spilled on towels etc all the time , they put it on womens hair and put them under a hairdryer to make it process faster.
I used to see people smoking while applying it to others hair.
Never seen a beauty shop explode in all my years.
There must be more to this story than is being told.
Terrorist are trying to buy this stuff in large volumes to make explosives which makes me wonder what else was in the car.

That 35% stuff was from a repackager that placed it in bottles that were oxidized by the peroxide, which made them brittle. Concentrations above 25% should not be made available to beauticians, because the stuff is too corrosive to the skin. ...mistakes would cause severe burns.

30%+ stuff can't be placed in passenger aircraft, even if it is packaged and labeled correctly. The "smoldering" of mail the report claims was probably steam caused by the heat generated by paper oxidation. As long as the water from the peroxide was present, it would not have burned. The heat would release steam and the oxygen from any remaining peroxide to the air w/o causing any additional problems, or risks.
