Detailed Product Description:
Colorless liquid. Odorless. Soluble in water and alcohol.
Commonly used in bleaching and deodorizing of textiles, and as a constituent
in cleaning agents in the semiconductor industry. Sometimes used as a substitute
for chlorine in water and sewage treatment.
This is 30% concentration, Semiconductor Grade, low-particulate, with
a minimum purity of 99.9%.
Hydrogen peroxide is a very pale blue liquid, slightly more viscous than
water, that appears colorless in dilute solution. It is a weak acid, has strong
oxidizing properties, and is a powerful bleaching agent. It is used as a
disinfectant, antiseptic, oxidizer, and in rocketry as a propellant. The
oxidizing capacity of hydrogen peroxide is so strong that it is considered
a highly reactive oxygen species.
Aqueous hydrogen peroxide solutions have specific properties that are
different from those of the pure chemical due to hydrogen bonding
between water and hydrogen peroxide molecules. Specifically, hydrogen
peroxide and water form a eutectic mixture, exhibiting freezing-point
depression. While pure water melts and freezes at approximately 273K,
and pure hydrogen peroxide just 0.4K below that, a 50% (by volume)
solution melts and freezes at 221 K.
H2O2 is one of the most powerful oxidizers known—stronger than
chlorine, chlorine dioxide, and potassium permanganate. Also, through
catalysis, H2O2 can be converted into hydroxyl radicals (OH) with
reactivity second only to fluorine.
Diluted H2O2 (between 3% and 12%) is used to bleach human hair when
mixed with ammonia. It is absorbed by skin upon contact and creates a
local skin capillary embolism which appears as a temporary whitening of
the skin. The strength of a solution may be described as a percentage or
volume, where 1% hydrogen peroxide releases 3.3 volumes of oxygen
during decomposition. Thus, a 3% solution is equivalent to 10 volume
and a 6% solution to 20 volume, etc.
3% H2O2 is used medically for cleaning wounds, removing dead tissue,
and as an oral debriding agent. Peroxide stops slow (small vessel) wound
bleeding/oozing, as well. Most over-the-counter peroxide solutions are
not suitable for ingestion.
3% H2O2 is effective at treating fresh (red) blood-stains in clothing and
on other items. It must be applied to clothing before blood stains can be
accidentally "set" with heated water. Cold water and soap are then used to
remove the peroxide treated blood.
The United States Food and Drug Administration (FDA) has classified
hydrogen peroxide as a Low Regulatory Priority (LRP) drug for use in
controlling fungus on fish and fish eggs.
Some horticulturalists and users of hydroponics advocate the use of
weak hydrogen peroxide solution ("Spanish water") in watering solutions.
Its spontaneous decomposition releases oxygen that enhances a plant's root
development and helps to treat root rot (cellular root death due to lack of
oxygen) and a variety of other pests.
Hydrogen peroxide is a strong oxidizer effective in controlling sulfide
and organic related odors in wastewater collection and treatment systems.
It is typically applied to a wastewater system where there is a retention
time of 30 minutes to 5 hours before hydrogen sulfide is released.
Hydrogen peroxide oxidizes the hydrogen sulfide and promotes bio-
oxidation of organic odors. Hydrogen peroxide decomposes to oxygen
and water, adding dissolved oxygen to the system thereby negating some
Biochemical Oxygen Demand.
Hydrogen peroxide is used with phenyl oxalate ester and an appropriate
dye in glow sticks as an oxidizing agent. It reacts with the ester to form
an unstable CO2 dimer which excites the dye to emit a photon of light
when it spontaneously relaxes back to the ground state.
Strong oxidizing agent at this concentration. Dangerous fire and
explosion risk when in contact with organics. Toxic and strongly
irritating to skin and tissue.
