Description and Uses

Trisodium phosphate (TSP) is an inorganic salt used as industrial detergents, metal treatment and in toilet floor cleaners. TSP is pure cleaning power. Used as a water softener; for the treatment of boiler water; as a paint remover; in photographic developers; for tanning leather; for manufacturing paper; for clarifying sugar.
Also, it is a common laboratory reagent. Use to dissolve dirt, grease, and mildew from siding, decks, masonry, boats, campers. To prepare surfaces before painting or staining wash with TSP. Trisodium phosphate is an approved food additive in the U.S., European Union and other countries of the world. It may be added to foods and beverages or smoothies and green drinks. The primary function of trisodium phosphate is acidity regulation. It is commonly present in dry, extruded cereals. Together with other phosphates, it modifies cereal color, aids the cereal's flow through the extruder and provides phosphorus fortification. It is also commonly present in cheese sauces as an emulsifier. Trisodium phosphate is a strong chemical and can cause severe eye damage and can burn unprotected skin. Poisoning occurs if you swallow, breathe in, or spill large amounts of this substance on your skin.

Trisodium Phosphate is an emulsifier and buffer that is strongly alkaline, with a ph of 12. it is moderately soluble in water, with a solubility of 14 g/100 ml at 25°c. it functions as an emulsifier in processed cheese to improve texture. it maintains viscosity and pre- vents phase separation in evaporated milk and is also found in cereals. it is also termed trisodium orthophosphate, sodium phosphate tribasic, and trisodium monophosphate.
