Poly(acrylic acid) is widely used as a thickening agent in various industries, including cosmetics, pharmaceuticals, and personal care products, due to its ability to absorb and retain water. In the field of water treatment, it serves as a dispersant to prevent the buildup of scale and deposits in pipes and equipment. It is also employed in detergents to enhance cleaning efficiency by binding to metal ions and preventing them from interfering with the cleaning process. In agriculture, poly(acrylic acid) is used in superabsorbent polymers to improve soil water retention, aiding in the growth of crops in arid regions. Additionally, it plays a role in the production of adhesives and coatings, providing improved bonding and film-forming properties. Its versatility and effectiveness make it a valuable component in numerous industrial and consumer applications.
