Poly(acrylic acid) is widely used in various industries due to its unique properties. In the personal care industry, it is a key ingredient in skincare and haircare products, acting as a thickener and stabilizer in lotions, creams, and gels. Its ability to retain moisture makes it effective in hydrating formulations. In the pharmaceutical sector, it is utilized in drug delivery systems, particularly in controlled-release tablets, where it helps regulate the release of active ingredients. In water treatment, poly(acrylic acid) serves as a dispersant and scale inhibitor, preventing the buildup of minerals in pipes and equipment. Additionally, it is employed in the production of superabsorbent polymers, which are essential in hygiene products like diapers and sanitary napkins, due to its high water absorption capacity. Its versatility also extends to industrial applications, such as adhesives and coatings, where it enhances performance and durability.
