description Product Description
Used as a cleaning agent in laundry detergents and household cleaners due to its ability to soften water and enhance stain removal. It is also employed in the production of fiberglass and ceramics, where it acts as a flux to lower melting points and improve material strength. In pest control, it serves as an insecticide to eliminate ants, cockroaches, and fleas. Additionally, it is utilized in the manufacture of enamel glazes and as a preservative in wood treatments to prevent fungal growth. In science labs, it is a key component in buffer solutions for maintaining pH stability.
