color=#000000 size=2 FAMILY="SANSSERIF">Sorry, that is a =
common
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. <BR><BR>Bill Bremmer RPT <BR>Madison, Wisconsin =
