If you’re formulating powdered detergents, you’ve almost certainly encountered sodium lauryl ether sulphate (SLES) as a high-performance surfactant and anhydrous sodium sulphate as a workhorse filler. While they are chemically distinct, these two raw materials often appear side-by-side in the same production batch. Knowing how each component functions—and where to source reliable, high-purity sodium sulphate—can directly influence your product quality, production costs, and supply chain resilience. As a leading Chinese exporter of fine chemicals, Hailei Chemical delivers industrial-grade anhydrous sodium sulphate that meets the exacting requirements of modern detergent, glass, and textile manufacturers.
