Applicaation of EPT Tripolyphosphate (STPP)94%
1)In detergents
The greater part of STPP is eaten as a component of industrial detergents.
It serves as a quotbuilder, quot EPT jargon for a h2o softener. In difficult h2o
(drinking water that contains higher concentrations of Mg2+ and Ca2+), detergents are
deactivated. Being a extremely chargedchelating agent, TPP5- binds to dications
tightly and prevents them from interfering with the sulfonate detergent.
2)Food programs

environment retarders, flame retardants, paper, anticorrosion pigments, textiles,
rubber manufacture, fermentation, antifreeze.
