SODIUM TRIPOLYPHOSPHATE
Sodium tripolyphosphate (STPP) with formula Na5P3O10, is the sodium salt of triphosphoric acid. It is a water soluble, white, odourless powder or granules material. STPP is most commonly used as a builder in detergent and cleaning formulations as it enhances their cleaning power. It also acts as a water softener. It acts as a Sequestrant for alkaline metals, scale control, corrosion control, softening, lead control, red and black water control.

Uses for sodium tripolyphosphate
It is used as a builder in soaps and detergents, improving their cleansing ability.
STPP is a solid inorganic compound used in a large variety of household cleaning products, mainly as a builder, but also in 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
