China is the dominant exporter of Poly-L-aspartic acid, accounting for the largest share of global shipments, while the United States, Germany, and South Korea are the leading importers. Poly-L-aspartic acid prices have remained relatively stable amid steady demand from water treatment and agricultural sectors. Exports from China have grown moderately over the past three years, while imports by the U.S. and EU member states have shown consistent year-on-year expansion, reflecting broadening industrial adoption.
Poly-L-aspartic acid is a water-soluble, white to off-white amorphous powder or granular solid with no characteristic odor and negligible volatility; it decomposes before melting and lacks a defined boiling point. It is a biodegradable, synthetic polyamino acid polymer derived from the L-enantiomer of aspartic acid, classified as a functional biopolymer and green chelating agent. Industrially, it serves primarily as a scale and corrosion inhibitor in water treatment systems, especially in cooling towers, boilers, and desalination plants, and as a dispersant and anti-precipitant in detergent formulations. Its applications span water treatment chemicals, industrial cleaning products, and enhanced oil recovery fluids, where it functions as a non-phosphate alternative to traditional phosphonate and polyacrylate-based additives.
