Introduction
Anhydrous Trisodium Phosphate (TSP), CAS number 7601-54-9, chemical formula Na₃PO₄, is a white crystalline powder with exceptional alkaline properties and excellent water solubility. As a leading global chemical manufacturer, SNOWHITE CHEMICAL CO., LTD. supplies high-purity anhydrous TSP to industrial and food processing customers worldwide.
Our product is available in two standard grades: industrial grade (≥96% purity) and food grade (≥97% purity), both manufactured under strict ISO 9001 quality management systems and certified by SGS and Halal.
Key Applications
Industrial Cleaning & Degreasing
TSP's high pH level (12 in 1% solution) makes it one of the most effective heavy-duty cleaning agents. It saponifies grease and removes stubborn organic residues from metal, concrete, and masonry surfaces. Common uses include:
• Industrial equipment degreasing
• Commercial kitchen sanitation
• Pre-painting surface preparation
• Masonry and brick cleaning
Water Treatment
In boiler and cooling tower systems, TSP prevents scale formation by binding with calcium and magnesium ions. It also:
• Adjusts and stabilizes water pH levels
• Inhibits metal surface corrosion
• Precipitates heavy metals from wastewater
Food & Beverage Processing
As an FDA-approved food additive (INS No. 339(iii)), food-grade TSP is used in regulated quantities to:
• Improve moisture retention in meat and seafood
• Stabilize emulsions in processed cheeses and dairy products
• Maintain consistent pH during food processing
• Enhance texture in baked goods and noodles
Other Industrial Uses
• Metal surface treatment for electroplating
• Ceramic production to lower firing temperatures
• Textile kier boiling and dyeing
• Leather tanning deliming
• Detergent manufacturing as a builder
