In hard water (water that contains high concentrations of Mg2+ and Ca2+), detergents are deactivated. Being a highly chargedchelating agent, TPP5- binds to dications tightly and prevents them from interfering with the sulfonate detergent.2.Food ApplicationsSTPP is a preservative for seafood, meats, poultry, and animal feeds.It is common in food production as E number 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 UsesOther 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.Product PackingPacking: In 25kg PP/kraft paper bag with PE liner.Storage and transport: It should be stored in a dry, ventilated and clean warehouse; kept away from moisture and heat. It should be stored separately from poisonous substances. Handled with care to avoid damage of the packings.Contact Detalis:Vanessa ZhaoSenior Business ManagerSHANDONG YURUN CHEMICAL CO.,LTDAdd: Yurun Building,Weifang City,Shandong Province,P.R.China.
