Used in the production of synthetic resins and polymers, itaconic acid serves as a key monomer in latexes, coatings, and paints due to its ability to enhance adhesion, water resistance, and stability. It is widely applied in superabsorbent polymers for disposable hygiene products like diapers and agricultural materials for soil moisture retention, offering an eco-friendly alternative to petrochemical-based acrylic acid. In the textile industry, it improves dyeability and flame retardancy of fabrics. Itaconic acid is also utilized in detergents, cleaning agents, and fabric softeners for its chelating properties, helping to soften water and boost cleaning efficiency. Additionally, it plays a role in the formulation of scale and corrosion inhibitors in industrial water treatment systems. Emerging applications include its use in biodegradable plastics, as a building block for bio-based chemicals in green chemistry initiatives, in antimicrobial agents, and as a precursor for pharmaceutical synthesis due to its modifiable structure and environmental safety.
