Sodium polyaspartate is widely used across various industries due to its environmentally friendly properties and high efficiency. In agriculture, it serves as a fertilizer efficiency enhancer, promoting nutrient absorption in plants and reducing nutrient loss from leaching. In water treatment and cleaning agents, it acts as an anti-scale agent, preventing calcium deposits, extending equipment lifespan, and reducing dirt buildup in industrial cooling systems, boilers, and detergents while enhancing cleaning efficiency. In the oil and gas industry, it functions as a corrosion inhibitor and controls sediment formation in cooling water systems. In textiles, it aids in dyeing and fiber conditioning. Additionally, it is utilized in personal care products for its moisturizing and conditioning properties.
