Applicaation of EPT Tripolyphosphate (STPP)94%
1)In detergents
The greater part of STPP is eaten as a element of industrial detergents.
It serves as a quotbuilder, quot EPT jargon for a water softener. In tough water
(h2o that consists of higher concentrations of Mg2+ and Ca2+), detergents are
deactivated. Currently being a very chargedchelating agent, TPP5- binds to dications
tightly and prevents them from interfering with the sulfonate detergent.
