Applicaation of Sodium Tripolyphosphate (STPP)94%

1)In detergents

The majority of STPP is consumed as acomponent of commercial detergents.

It serves as a"builder," industrial jargon for awater softener. In hard water

(water that contains high concentrations of Mg2+ and Ca2+), detergents are

deactivated. Being ahighly chargedchelating agent, TPP5- binds to dications

tightly and prevents them from interfering with the sulfonate detergent.

2)Food applications

STPP is apreservative for seafood, meats, poultry, and animal feeds.It is common

in food production as Enumber E451. In foods, STPP is used as an emulsifier and

to retain moisture. Many governments regulate the quantities allowed in foods,

as it can substantially increase the sale weight of seafood in particular. The UnitedStates Food and Drug Administration lists STPP as "generally recognized as safe.".

3)Other uses

Other uses (hundreds of thousands of tons/year) include "ceramics, leather

tanning(as masking agent and synthetic tanning agent -SYNTAN), anticaking,

setting retarders, flame retardants, paper, anticorrosion pigments, textiles,

rubber manufacture, fermentation, antifreeze.
