Poly(acrylic acid) is widely used as a thickening agent in various industries, including cosmetics and personal care products, where it helps to stabilize formulations and improve texture. In the water treatment sector, it acts as a dispersant and scale inhibitor, preventing the buildup of mineral deposits in pipelines and equipment. It is also employed in the production of superabsorbent polymers, which are essential components in hygiene products like diapers and sanitary napkins, due to their ability to absorb and retain large amounts of liquid. Additionally, poly(acrylic acid) is utilized in the pharmaceutical industry as a binder or disintegrant in tablet formulations, ensuring controlled drug release. In agriculture, it serves as a soil conditioner, enhancing water retention and promoting plant growth in arid regions. Its versatility and functional properties make it a valuable material across diverse applications.
