Description

Tri-Sodium Phosphate Hexahydrate is a highly versatile inorganic salt widely used as a cleaning agent, water softener, and pH buffer. Its value lies in its powerful sequestering and emulsifying properties, making it effective for removing heavy soils and scale. This compound is essential for manufacturers and formulators in the industrial cleaning, food processing, and water treatment sectors seeking reliable and efficient alkaline builders.

Application

• Industrial & Institutional Cleaning: A key builder in heavy-duty degreasers, metal cleaners, and floor cleaners for its superior emulsification of fats and oils.
• Food Processing & Sanitation: Used in approved formulations for equipment cleaning, sanitizing, and as a processing aid to adjust pH and soften water.
• Water Treatment: Acts as a corrosion inhibitor and scale control agent in boiler water and cooling tower systems.
• Textile Processing: Employed in scouring and bleaching baths to soften water and improve the efficiency of other chemicals.
• Paint & Coating Preparation: Serves as an effective surface cleaner and degreaser for metal substrates prior to painting or coating.
• Clay & Ceramic Production: Functions as a dispersant to improve the workability and consistency of slurries.
