Sodium
triphosphate (STP,
sometimes STPP or sodium tripolyphosphate or TPP) is an inorganic
compound with formula Na5P3O10.
-
It is the sodium salt
of the
polyphosphate
penta-anion, which is the conjugate base of
triphosphoric acid.
-
It is
produced on a large scale as a component of many domestic and
industrial products, especially detergents.
-
Polyphosphates are hydrolyzed into simpler phosphates, which in
moderate amounts are nutritious.
-
For
example, ATP, a related
derivative of triphosphate, is essential for life.
-
Thus, the
toxicity of polyphosphates is low, as the lowest LD50 after oral
administration is >1,000 mg/kg body weight.
-
Similarly,
no mutagenic or carcinogenec effects nor reproductive effects have
been noted.
-
Salts of
polyphosphate anions are moderately irritating to skin and mucous
membrane because they are mildly alkaline.
-
STPP can be
hydrolysed, finally to
orthophosphate, which can be assimilated by algae and/or
by micro-organisms.
-
STPP thus
ends up being assimilated into the natural phosphorus
cycle.
-
Reliable
published studies confirm
biochemical
understanding, showing that STPP is progressively hydrolysed by
biochemical activity in contact with waste waters (in sewerage pipes
and within sewage works) and also in the natural
aquatic environment.
-
As an effective dispersion agent for
suspension solutions of coatings, kaolin, magnesium oxide, calcium
carbonate and drilling mud etc.
