Trisodium phosphate was at one time extensively used in formulations for a variety of consumer-grade soaps and detergents, and the most common use for trisodium phosphate has been in cleaning agents. The pH of a 1% solution is 12 (i.e., very basic), and the solution is sufficiently alkaline to saponify grease and oils.
Phosphate-free detergents are sold as eco-friendly detergents. In the 21st century phosphates began to be reduced in percentage terms as an ingredient, leading to a New York Times report that said "low- or phosphate-free dishwasher detergents it tested, including those from environmentally friendly product lines that have been on the market for ...
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 ...
The powdered form must be mixed in water to use. A liquid version is also available. Although considered all-purpose, it is "not recommended for carpets, upholstery, aluminum, glass, laundry, or mixing with bleach or ammonia" as written on product label. [citation needed]
Bleach (pH 12) and ammonia (pH 11) are common alkaline cleaning agents. Often, dispersants, to prevent redeposition of dissolved dirt, and chelants, to attack rust, are added to the alkaline agent. Alkaline cleaners can dissolve fats (including grease), oils, and protein-based substances.
The development of bleach activators in the 1970s and 1980s allowed for cooler washing temperatures to be effective. These compounds, such as tetraacetylethylenediamine (TAED), react with hydrogen peroxide to produce peracetic acid, which is an even more effective bleach, particularly at lower temperatures. [4]
Sodium triphosphate (STP), also sodium tripolyphosphate (STPP), or tripolyphosphate (TPP), [1]) is an inorganic compound with formula Na 5 P 3 O 10.It is the sodium salt of the polyphosphate penta-anion, which is the conjugate base of triphosphoric acid.
Sodium dihydrogen phosphate Sodium hydrogen phosphate Trisodium phosphate. A sodium phosphate is a generic variety of salts of sodium (Na +) and phosphate (PO 3− 4).Phosphate also forms families or condensed anions including di-, tri-, tetra-, and polyphosphates.
