Sodium of polyaspartic acid is widely used as a biodegradable and environmentally friendly alternative to traditional water treatment chemicals. It effectively prevents scale formation and corrosion in industrial water systems, such as cooling towers and boilers, by sequestering metal ions and inhibiting mineral deposits.

In agriculture, it serves as a nutrient absorption enhancer, improving the efficiency of fertilizers by reducing nutrient leaching and promoting better uptake by plants. Its biodegradable nature makes it a sustainable choice for soil conditioning and crop management.

Additionally, it is utilized in detergents and cleaning products as a chelating agent, helping to soften water and enhance the performance of cleaning formulations without harming the environment. Its versatility and eco-friendly properties make it a valuable component in various industrial and consumer applications.
