DOWICIDE* A Antimicrobial is readily
soluble in water and in many polar
organic solvents. It is usually incorpo-
rated directly into the product being
preserved as a water or solvent
concentrate, or as the flake material.
DOWICIDE A Antimicrobial is Dow's
brand of sodium salt of o-phenylphenol,
tetrahydrate form.
Adhesive manufacturers incorporate
this antimicrobial into adhesives based
on starch, protein, natural and synthetic
gums, and latexes to protect the adhe-
sives against attack by bacteria and
mold during manufacture and storage,
and throughout their service life.
The leather industry utilizes
DOWICIDE A Antimicrobial in the
paste used in hide-parting operations;
and in sizing, finishing, and dressing
materials. Metal workers who prepare
their own metalworking fluids employ
this antimicrobial to protect the finished
fluid against spoilage. Pulp and paper
producers protect processing materials
with DOWICIDE A, and textile pro-
ducers utilize it to protect processing
materials as well as finished yarns
and cloth against the ravages of
microorganisms.
Additionally, DOWICIDE AAntimicrobial
is used to control mold growth in con-
struction materials and to preserve
many products such as automotive
polishes, ceramic glazes and clay slips,
cosmetics and toiletries, foam-type
fire extinguisher solutions, laundry
starch, plastic gaskets, polishing
compounds, polyvinyl alcohol, inks,
and floor wax emulsions.
When formulating DOWICIDE A
Antimicrobial into your product, it may
be added directly as the flake or as
an aqueous solution. The addition of
DOWICIDE A Antimicrobial to water
or a water-based formulation will
increase the pH due to the presence
of residual amounts of sodium hydroxide. The solubility of
DOWICIDE A is affected by pH
therefore, measures should be taken
to keep the pH of the formulation at 9
or above. The addition of organic
solvents or anionic emulsifiers may
aid in solubilizing DOWICIDE A.
However, DOWICIDE A is usually
incompatible with most other types
of surfactants or emulsifiers. Once
DOWICIDE A is solubilized, its activity
is independent of pH up to 12.8.
Paint For preservation of decomposable raw material solutions or dispersions during storage.
Ink For shelf preservation of dextrin-based watercolor printing inks.
