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 industrial water systems. 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 the pharmaceutical industry as a binder in tablet formulations and in the textile industry to improve dye absorption and fabric softness. Its adhesive properties make it valuable in coatings and paints, providing improved durability and water resistance.
