The global isosorbide market is estimated at USD 0.69 billion in 2025 and is projected to reach USD 1.07 billion by 2031, at a CAGR of 7.65% over the 2026-2031 forecast period, according to Mordor Intelligence. Isosorbide is a bio-based diol derived from glucose, used in bio-based plastics, plasticizers, coatings and pharmaceutical intermediates.

Isosorbide serves as a renewable building block for bio-based polycarbonates, polyesters and resins, and as a feedstock for bio-based plasticizers, offering an alternative to petroleum-derived diols and phthalates. Demand is tied to the expansion of bio-based polymer technologies, stricter regulation of fossil-derived chemicals and rising consumer preference for sustainable materials, with packaging, automotive and consumer-goods applications driving growth. Asia-Pacific is the fastest-growing region, supported by expanding bio-based material and packaging industries in China, India and Southeast Asia.

Europe and North America lead in premium bio-based polymer and specialty applications. Continued bio-economy growth positions isosorbide as a steadily advancing bio-based intermediate for plasticizers and polymers.
