Poly(acrylic acid) partial sodium salt is widely used as a superabsorbent polymer in personal care products such as diapers and sanitary napkins, where it efficiently absorbs and retains large amounts of liquid. In agriculture, it serves as a soil conditioner, improving water retention in arid regions and enhancing plant growth. It is also employed in detergents and cleaning agents as a dispersant and anti-redeposition agent, preventing dirt from settling back onto fabrics. Additionally, it finds application in water treatment processes as a scale inhibitor and flocculant, helping to remove impurities and improve water quality. In the pharmaceutical industry, it is used as a thickening agent and stabilizer in various formulations. Its versatility and effectiveness make it a valuable component across multiple industries.
