Uses Trisodium phosphate (TSP) is a cleaning agent, lubricant, food additive, stain remover and degreaser. It is an alkaline cleaning agent that has been used as a household cleaner for many years, but ecological problems have largely ended that practice, at least in the western world. Substitutes are not as effective, but the raw chemical can be bought in bulk to add to other detergents. It works by disrupting the bacterial cell membrane and causing the contents to leak out, though the exact mechanism is not fully elucidated (Oyarzabal, 2005). Trisodium phosphate solutions are approved for treatment of beef carcasses in the US Code of Federal Regulations (21 CFR 182.1778; FDA 2003).

By the end of the 20th century, many products that formerly contained TSP were manufactured with TSP substitutes, which consist mainly of sodium carbonate along with various admixtures of nonionic surfactants and a limited percentage of sodium phosphates. TSP is commonly used after cleaning with mineral spirits in order to remove hydrocarbon residues. TSP may be used with household chlorine bleach in the same solution without hazardous reactions. This mixture is particularly good for removing mildew, but is ineffective at permanently removing mold.

Uses sodium phosphate helps maintain product pH.

Uses 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.
