Application

Sodium phosphate serves multiple purposes across various industries due to its highly soluble and alkaline properties. Primarily, it functions as a powerful cleaning agent, food additive, stain remover, and degreaser. Commercially available in several hydrated forms, sodium phosphate is effective in preparing surfaces for painting by breaking down the gloss and opening the pores of existing paint layers, enhancing paint adhesion. It finds additional applications in metal treatment, acting as an approved flux in soldering medical-grade copper plumbing, and as an acidity regulator in food processing. As a food additive, it helps maintain product pH and modifies cereal color, contributing to smooth processing and phosphorus fortification. In the industrial realm, sodium phosphate is used in detergents, boiler water treatment, and as a water softener. However, caution is advised as it can cause severe skin and eye irritation.
