Producing technology:

Wet process and Thermal process combined to improve product purity and save energy.

 

Application:

 

Main part being used as sapide helps the agent , soap synergist , water softener,In detergents

The majority of STPP is consumed as a component of commercial detergents. It serves as a "builder," industrial jargon for a water softener. In hard water (water that contains high concentrations of Mg2+ and Ca2+), detergents are deactivated. Being a highly charged chelating agent, TPP5- binds to dications tightly and prevents them from interfering with the sulfonate detergent.[5]

 

It has got salient chelating capacity to metal ions of Ca and Mg etc. and can soften hard water to make suspension into solution, alkalinity, without causticity .

 

It is a surfactant, and has got outstanding emulsification to lubricants and fat.
