Used in the production of synthetic resins and polymers, itaconic acid serves as a key monomer in copolymers for coatings, adhesives, and latex applications due to its ability to enhance water resistance and durability. It is also employed in detergents as a chelating agent, replacing less biodegradable alternatives. In the biomedical field, itaconic acid derivatives are explored for drug delivery systems and biocompatible materials. Additionally, it finds use in the formulation of superabsorbent polymers for hygiene products and agriculture, where it contributes to moisture retention. Its antimicrobial properties make it suitable for use in cosmetics and personal care products as a preservative. Ongoing research focuses on its potential in sustainable plastics and green chemistry initiatives.
