Poly(acrylic acid) is widely used as a thickening agent in various industries, including cosmetics and personal care products, where it enhances the viscosity and stability of formulations like lotions, creams, and gels. In the water treatment sector, it acts as a dispersant and scale inhibitor, preventing the buildup of mineral deposits in pipes and equipment. It is also employed in the production of superabsorbent polymers, which are essential components in hygiene products such as diapers and sanitary napkins, due to their ability to absorb and retain large amounts of liquid. Additionally, poly(acrylic acid) is utilized in adhesives, coatings, and paints to improve their binding properties and durability. In the pharmaceutical industry, it serves as a drug delivery agent, enabling controlled release of medications. Its versatility and functional properties make it a valuable material across diverse applications.
