Usage areas of Trisodium phosphate

Trisodium phosphate (TSP) is the inorganic compound with the chemical formula Na3PO4. It is a white, granular or crystalline solid and is highly soluble in an alkaline solution. TSPs are used as a cleaning agent, lubricant, food additive, stain remover and degreaser.

The trade item is mostly partially hydrated and can range from anhydrous Na3PO4 to the dodecahydrate Na3PO4.12H20. Mostly available in white powder form, it may also be called trisodium orthophosphate or simply sodium phosphate.

Usage areas

• Photo enhancers, boiler scale removal and scale prevention, water softening, detergent blending, wet finish-pH adjuster, aluminum workpieces, varnishes, sugar bleaching, food fermentation, supplementary mineral enrichment for livestock nutrition etc. It is used in a wide variety of fields.
• Tri sodium phosphate is a cleaning and degreasing agent mostly used to prepare domestic surfaces for painting.
• Most latex paints, including milk paint on furniture, can be removed by rubbing with a strong solution of TSP.
• Once any piece of wood has been stripped, TSP can be used to remove the wax found in most paint removers.
• TSP is also used to completely clean the mineral extracts after washing with mineral extracts.
• TSP can be found in the same solution as household chlorine bleach, which is especially good for removing mold from wood.

It wasn’t so long ago that trisodium phosphate (TSP) was a go-to choice for tough cleaning jobs, especially on exteriors. Diluted in water and applied often with a stiff scrub brush, it can remove stubborn grease stains and mold and mildew growth. In recent years, however, the popularity of TSP has waned. There are no complaints about its performance—TSP was and remains a highly effective cleaner. Rather, an increasing number of people are steering clear of cleaning with TSP simply because, due to its potency, working with the stuff can pose dangers to personal health and the environment.
