Poly(acrylic acid) solution is widely used in various industries due to its versatile properties. 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 detergents and cleaning products as a chelating agent, enhancing their effectiveness by binding to metal ions in hard water.

In the personal care industry, it is utilized in cosmetics and skincare products as a thickening agent, stabilizer, and moisturizer, improving the texture and performance of formulations. Additionally, it serves as a superabsorbent polymer in hygiene products like diapers and sanitary pads, efficiently absorbing and retaining liquids.

In agriculture, poly(acrylic acid) solution is used in soil conditioners to improve water retention and nutrient availability, promoting healthier plant growth. It also finds applications in the textile industry as a finishing agent to enhance fabric properties such as softness and wrinkle resistance. Its ability to form gels and films makes it valuable in adhesives, coatings, and pharmaceutical drug delivery systems.
