Trisodium Phosphate

Brief Overview

Trisodium phosphate appears as a white granular solid with a chemical formula of Na₃PO₄. It is highly soluble in water and is widely used in several applications, such as cleaning agents, lubricants, and food additives.

Manufacturing Process

Trisodium phosphate is produced through a neutralization reaction between sodium hydroxide and disodium phosphate, which is produced using sodium carbonate and phosphoric acid.

Na₂CO₃ + H₃PO₄ → Na₂HPO₄ + CO₂+ H₂O

Na₂HPO₄ + NaOH → Na₃PO₄ + H₂O

Food Additive

Trisodium Phosphate is commonly used as an acidity regulator and has the collective E number E339.

Detergent Industry 

Trisodium phosphate is used widely in detergents to saponify grease and oils. When combined with surfactants, it is an excellent cleaning agent for various applications, from laundry to cleaning concrete surfaces.

Paint Industry 

Trisodium phosphate is used to degrease and deglossing of walls, giving a better surface for more excellent paint adhesion.
