Hydrogen
Peroxide
Our hydrogen peroxide is available in various standard and
specialty grades, differentiated by the stabilizer packages
appropriate for the specific end use. Each grade is available in up
to three different concentrations ranging from 35 to 70%. Solvay
Interox products for the semiconductor industry feature some of the
world's most pure hydrogen peroxide.
Standard Grades
Technical Grade hydrogen peroxide is our most commonly used
grade. It is stabilized with tin compounds that protect the product
from decomposition during transport and storage. Dilution Grade
hydrogen peroxide also stabilized with tin. It is more heavily
stabilized than Technical Grade hydrogen peroxide to accommodate
on-site dilution with an approved water source. Chemical Grade
hydrogen peroxide is formulated with a tin-free organic stabilizer.
It is most commonly used by the chemical processing industry in
applications that cannot tolerate the presence of tin. Typical
product applications for these grades are described below.
Pulp and
Paper
Hydrogen peroxide is
commonly used to brighten, delignify and control environmental
upsets. In chemical pulp mills,
hydrogen peroxide can be used to both delignify and brighten.
Since it will effectively replace a portion of the chlorine
dioxide requirement in a conventional kraft bleach sequence, and
it is an excellent option for the bleacher that needs to increase
brightness, increase throughput or lower bleaching costs.
For mechanical pulp, hydrogen peroxide is the only
brightening solution that will provide high brightness gains
(>15 brightness points) while preserving yield. In secondary
fibre processing, hydrogen peroxide is a versatile brightener. It
can be used in the pulper, disperger, or in a traditional tower
post-bleach.
Textiles
Hydrogen
peroxide is commonly used for textile bleaching and desizing. It
is widely used on natural cellulosic fibers (cotton, flax, linen,
jute, etc.), protein fibers (wool, silk, etc.) and synthetic
blends. Hydrogen peroxide is also effective on regenerated
cellulose fibers.
Environmental
Hydrogen peroxide is a
proven, cost-effective solution for a variety of water, soil, and
toxic air emissions. Refineries, chemical plants, paper mills,
municipalities, soil remediators and many other types of
operations use hydrogen peroxide. With it, they treat or control
aldehydes, phenols and other aromatic compounds, reduced sulphur
compounds, chlorine, cyanides, NOx, SOx, BOD, COD and several
other pollutants.
Chemical
Synthesis
Hydrogen peroxide and
its in-situ derivatives are powerful oxidizing agents that are
environmentally attractive, yet capable of oxidizing a wide range
of organic compounds. Hydrogen peroxide is widely used in
epoxidation and hydroxylation reactions and it is an excellent
choice in oxidative cleavage reactions and for oxidizing ketones,
aldehydes, alcohols, organic nitrogen and organic sulphur
compounds. Hydrogen peroxide can also be used is a variety of
solvent systems since it is soluble in water, many organic
solvents or the substrate itself.
Specialty Grades
Cosmetic Grade hydrogen peroxide is very heavily stabilized
to provide extra stability and extended shelf life in a variety of
formulated consumer products. It also meets U.S. Pharmacopeia
specifications when properly diluted to 2.5-3.5% concentrations.
Food Grade hydrogen peroxide is lightly stabilized to meet
the purity requirements of the Food Chemical Codex. PFPTM hydrogen peroxide is a specially
formulated product for use in immersion-type aseptic packaging
machines. PFPTM hydrogen peroxide
eliminates the need to add supplemental stabilizers at the point of
use, thereby mitigating the effects of stainless steel processing
equipment or other possible contaminants.
Consumer
Products
Hydrogen peroxide is
used in laundry bleaches that are gentle to fabrics and dyes,
topical solutions which fight germs without staining, contact lens
cleaning solutions and as chlorine-free household cleaners and
wood bleach formulations.
Food
Processing
Solvay Interox Food
Grade hydrogen peroxide is approved for use in such FDA approved
applications as bleaching instant tea, tripe and dietary fibre and
as a sanitizer of polymeric food-contact services used in
packaging (see 21 CFR sections 133 through 184 for a complete list
of approved uses). When used in food
applications, hydrogen peroxide dosing is controlled to minimize
the amount of residual hydrogen peroxide. However, any remaining
residual normally decomposes to oxygen and water in any subsequent
processing steps.
