TRISODIUM PHOSPHATE

Trisodium phosphate (STP) is formed by neutralizing phosphoric acid with sodium hydroxide.

TSP is an inorganic compound that appears as a white, granular or crystalline solid, and is highly soluble in water.

TSP is prized for its ability to effectively cut through grease and stubborn stains, making it a staple in heavy-duty cleaning products. It finds extensive use in detergents, household cleaning, particularly for preparing surfaces for painting and cleaning tough stains from walls, floors, and other hard surfaces. The compound’s ability to break down organic matter also makes it an effective mold and mildew remover.

Trisodium phosphate (TSP) is used in the manufacture of a wide range of detergents. It is an effective cleaning agent when used with surfactants for anything from laundry to concrete surfaces. A 1% solution has a pH of 12 (extremely basic), and it is alkaline enough to saponify fats and oils.
