Trisodium phosphate* (TSP, E339) is a cleaning agent, food additive, 
stain remover and degreaser <http://en.wikipedia.org/wiki/Degreaser>. It 
is a white, granular or crystalline solid, highly soluble in water 
producing an alkaline solution. The item of commerce is often partially 
hydrated and may range from anhydrous trisodium phosphate, Na_3 PO_4 , 
to the dodecahydrate, Na <http://en.wikipedia.org/wiki/Sodium>_3 P 
<http://en.wikipedia.org/wiki/Phosphorus>O 
<http://en.wikipedia.org/wiki/Oxygen>_4 �12H_2 O. Most often found in 
white powder form, it can also be called *trisodium orthophosphate* or 
just plain *sodium phosphate*. Trisodium phosphate was at one time 
extensively used in formulations for a wide variety of consumer grade 
soaps and detergents, 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.^ <http://en.wikipedia.org/wiki/Trisodium_phosphate#cite_note-2>
