Product Overview
Following are the specifications of Sodium Tripolyphosphate (STPP): TEST MEANS: GB9983-2004 Excellent : Total Phosphate (As P2O5), %a Y 68.0 Non-Active Phosphate (P2O5), %a 7.5 pH 5.8-7.3 I Grade : Total Phosphate (As P2O5), %a Y 67.0 Non-Active Phosphate (P2O5), %a 8.0 pH 5.8-7.3 Acceptable : Total Phosphate (As P2O5), %a Y 65. 0 Non-Active Phosphate (P2O5), %a 10.0 pH 5.8-7.3 Applications: STPP is a solid inorganic compound used in a large variety of household cleaning products, mainly as a builder, but also in human foodstuffs, animal feeds, industrial cleaning processes and ceramics manufacture. STPP is widely used in regular and compact laundry detergents and automatic dishwashing detergents (in powder, liquid, gel and/or tablet form), toilet cleaners, surface cleaners, and coffee urn cleaners. It also provides a number of chemical functions including: sequestration of "water hardness", enabling surfactants to function effectively; pH buffering; dirt emulsification and prevention of deposition; hydrolysis of grease; and dissolving-dispersing dirt particles.
