thanks for peroxide info...accuracy meter is spot on!


did a cross check on what might be in the bottle of
generic "pharmacy" grade H2o2. Only inert ingredient listed on bottle is distilled water. Where did they hide
the "extra stuff"?. hmm..says contains "stabilized" H2o2.
Wonder what that means..

ping the interweb with the goooogler.

ah...this looks promising.."ask a scientist"..from the
Argonne National Lab..asking exactly my question too!
And amplifying info about stabilizers from US PEROXIDE.
[.always nice to get information straight from "the horses mouth".so to speak.

*wow..had NO idea there was so much..."stuff" in the
bottle of hydrogen peroxide..

Stabilized Hydrogen Peroxide

Question - I was checking out this bottle of hydrogen
peroxide, and I noticed that it referred to the H2O2 (Hydrogen-Peroxid) content
being "Stabilized." I was wondering, how does one go about
stabilizing an oxidant, particularly one this simple, without
losing the desired oxidative properties all together?
----------------------------------------------
There are a number of compounds used to stabilize hydrogen
peroxide, the choice depends upon the concentration of peroxide and
the intended use. Typical stabilizers are organo tin compounds and
various organic compounds. See for example:

For more detailed information a
Google search on "hydrogen peroxide stabilizers" will provide more
detailed information on what and how hydrogen peroxide is stabilized.

What are H2O2 (Hydrogen-Peroxid) stabilizers and will they affect my application?

Date Created: 12/18/2009

Last Updated:
Most commercial grades of H2O2 (Hydrogen-Peroxid) contain chelants and sequestrants which minimize its decomposition under normal storage and handling conditions.

The types of stabilizers used in H2O2 vary between producers and product grades. Common stabilizers include:

Colloidal stannate and sodium pyrophosphate (present at 25 - 250 mg/L) are traditional mainstays.

Organophosphonates (e.g., Monsanto's Dequest products) are increasingly common.

Nitrate (for pH adjustment and corrosion inhibition) and phosphoric acid (for pH adjustment) also are used.

Colloidal silicate is used to sequester metals and thereby minimize H2O2 decomposition in certain applications that depend on the bleaching ability of H2O2 in alkali.

In some applications (e.g., copper etching or cosmetic formulations) a high degree of stabilization is needed; whereas, in others (e.g., drinking water treatment or semiconductor manufacture) product purity is more important. For most environmental applications, H2O2 stabilization does not affect product performance.

now as for what those "things" might do to the
human organism...more study required. Suffice to
say "cleaner is better".
