misconception.
"40 Volume" is not the same as 40%. <BR>I honestly forget =
what
the meaning of "volume" is for these products, it's <BR>been a long =
time since
I did that kind of work but I remember being <BR>misinformed in the =
same way
back then. If you were to put a solution of <BR>something on =
your hair
that is really 40% Hydrogen Peroxide (H2O2), it would <BR>chemically =
"cook" it
to the point of destruction and your scalp would be <BR>burned =
severely as
well. <BR><BR>In a nutshell, the worst of the discoloration of ivory =
is in the
oxidized <BR>surface. Often a simple cleaning, sometimes with a =
mild
abrasive followed by <BR>buffing will renew their color sufficiently. =
If
the cleaning with a mild <BR>abrasive isn't enough, using the 35% H2O2 =
solution in repeated applications <BR>under either natural or =
artificial
ultraviolet light will lighten their color. <BR><BR>You have to =
specially ask
for this chemical because it is very strong and <BR>potentially =
dangerous.
Whatever the beauty supply house has, even its <BR>strongest is =
nowhere
near this strong, I'm guessing 10 or 12%. It is the <BR>same =
solution as
the 3% H2O2 that you may have in your medicine cabinet, just <BR>more =
than 10
times as concentrated. H20 is water as you know it. In =
H202,
<BR>the extra Oxygen molecules are a classic example of the often =
talked about
<BR>"free radical". The H2O2 molecule wants to rid itself of =
that extra
oxygen <BR>molecule, so it will give it off to nearly anything. =
<BR><BR>It is
a very unstable compound that wants to stabilize itself into just =
plain
<BR>H20. That extra Oxygen molecule will *oxidize* anything it =
can.
When the <BR>concentration of H2O2 is very high in a solution, =
it
becomes a very powerful <BR>corrosive or catalyst. Yet, it =
really does
take this much chemical strength, <BR>plus dangerous and harsh =
ultraviolet
light in *repeated* applications to <BR>really have a significant =
bleaching
effect on ivory. <BR><BR>Consider this when weighing the factors about =
how
much this should cost and <BR>which precautions should be taken. =
