Sodium Phosphate is offered in two grades namely Technical Grade and
Extra Pure A. R. Grade.
Mono Di & Tri Sodium Phosphate
This is a generic term for the
salts
of sodium
and phosphate. They are:
Monosodium phosphate (H2NaO4P)
Disodium
phosphate (HNa2O4P)
Trisodium phosphate (Na3O4P)
Mono Sodium Phosphate (NaH2PO4, MSP),
also known as anhydrous monobasic sodium phosphate, is used as a
laxative and, in combination with other
sodium phosphates, as a
pH buffer.
The pKa is 7.20. The sodium chloride
equivalent value, or E-Value, is 0.49. It is soluble in 4.5
parts water. It is most commonly available as colorless crystals
or a white powder. It is insoluble in alcohol.
It is used in animal
feed, toothpaste, evaporated milk. It is also used for water
treatment to boiler, as buffering agent to acidity, detergent,
cleaning agent, dyeing flux, for tanning and electroplating. For
food additive it is mainly used as buffering agent,
emulsification agent, nourishment, etc. Gerald F. Judd, PhD
wrote a book, Good Teeth Birth to Death, which is well
documented, and gives instructions for the use of monosodium
phosphate to restore tooth enamel.
Di Sodium Phosphate (Na2HPO4, DSP)
is a sodiumsalt of
phosphoric acid.
It is a white powder that is highly
hygroscopic and
water soluble.It is
therefore used commercially as an anti-caking additive in powdered products. It
is also known as disodium hydrogen orthophosphate, sodium hydrogen phosphate or
sodium phosphate dibasic. It is commercially available in both the hydrated and
anhydrous forms.
Other uses
DSP can be used in cream of
wheat to quicken cook time. It is used as an anti oxidaant synergist, stabi;iser
and buffering agent in food. It is also used as an emulsifier in the manufacture
of pasteurized processed cheese. It is added to powdered milk to
prevent gelation.
It is used in conjunction
with trisodium phosphate
in many steam boiler applications. It supplies the inventory of free phosphates
to retard calcium scale formation. Typical
products include processed meat products, processed cheese products, powdered
milk, toothpaste.

Tri Sodium Phosphate (TSP),
available at most hardware stores in white powder form, is a cleaning agent,
stain remover and degreaser, commonly used to prepare surfaces for painting. It can also be
called trisodium orthophosphate and has the
chemical formula
Na3PO4; however, it is generally found in hydrated forms. It is a highly
water-soluble ionic salt. Solutions of it dissolved in water have an
alkalinepH.
It can also be found as a food additive; it
is used as an acidity
regulator (buffering
agent), emulsifier,
thickening agent,
nutrition enlargement agent and
sequestrant (metal-chelating
agent). In these uses, all
sodium phosphates
may be collectively referred to as sodium phosphate, or by
E number E339. The
same is true when sold as an
enema, working as
a laxative to
treat constipation.
Sodium phosphate enemas are sold
over-the-counter
in the United States. However, it should not be confused with the related
compounds sodium
dihydrogen phosphate, also known as monosodium phosphate or MSP, and
disodium phosphate.
Similar chemicals were once common in
laundry and
dishwashingdetergents, but
the phosphate,
being a fertilizer,
would cause algal blooms
in the bodies of water that the drains led to. In the early
1970s the use of
phosphate-containing products was limited. Now products sold as
TSP Substitute,
containing 80–90% sodium
carbonate, are promoted as a direct substitute.
Cleaning products labeled as TSP may
contain other ingredients as well, and may in fact be less than half TSP. So
even "regular" TSP found at the hardware store may be half TSP and half "TSP
substitute". Some large home improvement centers that sell paint no longer offer
TSP.
Although it is the active ingredient in at
least one toilet bowl cleaning tablet, TSP is generally not good for cleaning
bathrooms, because it can corrode metal.
TSP is commonly used after cleaning with
mineral spirits in
order to then clean up all the mineral spirits. TSP may be used with household
chlorine bleach in
the same solution, and this is particularly good for removing
mildew from wood.
The TSP alone can cause dark stains on
redwood, and
bleach prevents it.
Also used in various forms as a boiler
treatment chemical for calcium precipitation, as well as regulating the caustic
effects of disodium
phosphate in coordinated phosphate chemistry.
Also used to clean swimming pool polyester
filter elements.
Sodium phosphates are only used as
food
additives. Sod. phosphates are added to many foods as an
emulsifier
to prevent oil separation. Some examples are processed cheeses, processed meats,
ready-made meals and tinned (canned) soups. Sod. phosphates are also commonly
added to powdered soups, boullions and gravy mixtures.
Sod. phosphates can also be used as a
leavening
agent. Some examples of these foods include the batter coating on breaded
fish or chicken, and commercially baked cakes.
Adding sodi. phosp. to food increases the shelf life of
the food, maintaining the texture and appearance of the food. Typical uses
include cereal food, toothpaste and processed cheese.
