Trisodium phosphate (TSP) is an inorganic compound with the chemical formula Na 3 P O 4. It is a white, granular or crystalline solid, highly soluble in water, producing an alkaline solution. TSP is used as a cleaning agent , builder , lubricant , food additive , stain remover , and degreaser .
The comparable cleaning product in Canada and the US is trisodium phosphate, also known as "TSP". However, due to environmental concerns about the impact of phosphorus on lakes and streams, products labeled TSP may not actually contain any trisodium phosphate. "Sugar Soap" in the US is generally a cosmetic product. If sugar is actually used in ...
[25] [26] [4] [27] [28] Similarly, testing found that phosphate bans in laundry detergent led to newer products which did not clean clothes as well but still could compete with the older products containing phosphate. [29] [30] A 1973 paper in psychology predicted a consumer response from the perspective of removing a behavioral freedom. [31]
Purposes of cleaning agents include health, beauty, removing offensive odors, and avoiding the spread of dirt and contaminants to oneself and others.

The modern cleaner was invented by housewives Elizabeth "Bet" MacDonald and Naomi Stenglein in Saginaw, Michigan in 1933. [ citation needed ] Their formula included equal parts of ground-up glue , sodium carbonate , and trisodium phosphate ; though trisodium phosphate is no longer part of the modern formula out of a concern for environmental ...
Sodium tripolyphosphate is produced by heating a stoichiometric mixture of disodium phosphate, Na 2 HPO 4, and monosodium phosphate, NaH 2 PO 4, under carefully controlled conditions. [2] 2 Na 2 HPO 4 + NaH 2 PO 4 → Na 5 P 3 O 10 + 2 H 2 O. In this way, approximately 2 million tons are produced annually. [3]
