Default Who sells hydrogen peroxide?

No trouble getting 25 litres, or half a litre, but I'm looking for 5
litre packaging (30% conc). A web search might be easier if I knew which
trades use it. I'm sick of reading about hairdressing and teeth whitening.
Thanks for any pointers.

Well it's definitely used for cleaning contact lenses; Boots will sell
you 200mL of a 1% solution for a couple of quid. But I doubt that helps
much! I think it's manufactured by Ciba Vision.

Lab suppliers like http://www.sigmaaldrich.com will sell it I'm sure,
but at a price and probably not to the general public, if that's what
you are!

If you can get 25L or 0.5L, seems odd you can't find 5L?

Unless you want armed response teams bursting into your house in the middle

No trouble finding a 200 litre drum either.
Wood finishing suppliers have 5L as part of a 2 pack bleach but I don't
need the other part.
IIRC it's used in agriculture

Not a hope. A few weeks ago it would have been difficult, now it will be
impossible.

Why would you need 30% anyway? - that's pretty pokey stuff. For wood
bleaching I can't imagine you needing more than a litre or so.

Why should he? If he'd annoyed them they could've given him at least a
few hours of uncomfortable questioning, the anti-terrorism powers being
what they are.
After a chat they went away. Apparently suppliers of any electronic bits
that could be used to trigger bombs are told to inform the "authorities"
when orders come from certain areas.

I remain unconvinced

The Germans used concentrated hydrogen peroxide as a propellant for their V-1
flying bomb. It was used to rapidly generate steam for the launching catapult.
They called it T-Stoff.

As most German rocket development went to America after the war, perhaps
N.A.S.A. could give you a lead :-)

The V1 was a pulse jet powered by petrol.

The V2 was the rocket and use hydrogen peroxide as an oxidant.

Also used on one of their rocket propelled fighters, Heinkel,Me 262 or
something; some otaku anorak will know. The planes used to crash
frequently on take off or landing. I've read that if the pilot escaped
instant cremation, he'd probably get dissolved by the hydrogen peroxide.

He163 and Me262 were both jet aircraft. They may have carried H2O2 as some
auxiliary fuel, I suppose. I can't see a `rocket-propelled fighter' being
very practical: it would be in-theatre swiftly, out-of-theatre equally

Utter desperation. They shot down lots, if developed better & earlier
in the war, they'd probably have won it. I've heard from a reliable
source (ex-bomber gunner) that if one decided to pick on you, then
you'd probably be dead very shortly. Far faster than anything else in
the sky and very little you could do about it. Allied fighters used to
loiter in the area of the Luftwaffe airfields to try to nail them as
they glided in to land; no hope of catching one in flight.

Just to add my bit of pedantry, the Me262 was a jet, the Me163 was a rocket
powered aircraft. There was a rocket powred He 176, but as far as I am aware
no He-163. At the stage of the war it was used it was a very practical
aircraft, in that the 'theatre' was German cities subject to mass daylight
bombing raids. The Me163 could sit around and wait for the massed raids to
come over, then fly to altitude, attack at speeds that allied aircraft
couldn't hope to deal with, and be back on the ground within minutes.
However by the time they were deployed Germanies infrastructure and
manufacturing were so disrupted that they couldn't be bult in the quantities
required They only built a few 100, and they could never deploy them in
numbers to do real damage. It is estimated that they shot down about 10
allied planes for 15 Me163s lost in combat, but that hundreds of Me163 were
destroyed in landing or takeoff, or due to airfarme failure when mucking
about at the edge of the sound barrier. There is a Me-163 in the Science
museum in London.

Just to bring things back to D-I-Y - go to
http://www.stormbirds.com/project/index.html and
you too can dream of building an Me-262 n your shed!

Never seen or heard of that before---but it's just plain silly. Or
desperate. Just as a matter of interest, did any of them ever shoot
anything down?


Not many thankfully. More info here

I either meant 162 or 178, Google suggests. I'm not sure. A Close Relative
spent a fair amount of time in Germany in 1946/7 translating engineering
documentation on various fascinating projects (V1, V2, Schmetterling,
Me/He??? for various values of ???) and as a result has such a headful of
stuff that was secret for so long that he's only ever mentioned it in recent
years and tends to get them mixed up, and all I have is mixed-up hearsay.
Whichever one it was had a nasty habit of falling out of the sky in
increasingly small bits, anyway.

They only built a few 100, and they could never deploy them in
numbers to do real damage. It is estimated that they shot down about 10
allied planes for 15 Me163s lost in combat, but that hundreds of Me163 were
destroyed in landing or takeoff, or due to airfarme failure when mucking
about at the edge of the sound barrier. There is a Me-163 in the Science
museum in London.


That's perilously close to suicide missions, then, and not the war-winning
weapon others might have us believe.

No trouble getting 25 litres, or half a litre, but I'm looking for 5
litre packaging (30% conc). A web search might be easier if I knew
which trades use it. I'm sick of reading about hairdressing and
teeth whitening. Thanks for any pointers.


The Germans used concentrated hydrogen peroxide as a propellant for
their V-1 flying bomb. It was used to rapidly generate steam for the
launching catapult. They called it T-Stoff.

As most German rocket development went to America after the war,
perhaps N.A.S.A. could give you a lead :-)


Remind me what the C-Stoff was that they mixed with it to make it go bang?

Isn't so much 'war-winning' about timing? If the Me163 had been operational
in
substantial quantities in 1943 the daylight bomber offensive would probably
have
been abandoned and therefore the war would have progressed diffrently, but
that
sort of speculation is fairly fatuous, because it wasn't. A better case can
be made
for the rather more deadly Me 262 as a war winning weapon, if had been put
into
service soonr, although that had atrocious reliability problems.

So, anyone on Leeds who buys a e.g. 555 or a shift register gets leant

I don't think so


I wonder if it could be simply looking for identical components from
previous bombs?

And anyway, given the hundreds of mail order components suppliers, the
chances of anyone with serious intent not ordering seperately is
small.
