Itaconic acid is extensively researched as a bio-based precursor for the production of methacrylic acid (MAA). Catalytic decarboxylation converts itaconic acid directly into MAA, a key monomer for poly(methyl methacrylate) (PMMA) plastics. This pathway offers a bio-based route to produce transparent polymers like Plexiglas without petroleum feeds.

The Itaconic Acid Market size is expected to reach US$ 160.3 Million by 2033 from US$ 115.4 Million in 2025. The market is estimated to record a CAGR of 4.19% from 2026 to 2033. Growing interest in bio-based chemicals and sustainable alternatives to petroleum-derived materials is supporting the adoption of itaconic acid across several industries. Its renewable production potential, versatile chemical properties, and compatibility with various polymer systems make it an increasingly relevant material for manufacturers seeking improved environmental performance and innovative product formulations.

Itaconic acid is gaining attention as industries focus on developing materials with lower environmental impact.
