Introspective Market Research (IMR) today announced its Bio-Based Propylene Glycol Market Report, which projects strong global growth for this renewable chemical intermediate. According to IMR’s analysis, the bio-based propylene glycol (Bio-PG) market — currently valued in the low-hundreds of millions — is expected to reach approximately USD 611.6 million by 2032, growing at a compound annual growth rate (CAGR) of ~11.2% during the forecast period.

This expansion is fuelled by increasing regulatory pressure on petrochemical-derived glycols, rising consumer demand for green and biodegradable ingredients, and expanding applications in unsaturated polyester resins, antifreeze, solvents, and personal care. Advances in production technology—particularly from renewable feedstocks such as glycerin and corn-derived sugar—are making Bio-PG more cost-competitive and scalable.

What Opportunities & Trends Are Emerging?

Can bio-based PG become the standard solvent for green formulations?
Yes — regulations and consumer preference are pushing formulators toward renewable, low-toxicity alternatives, and Bio-PG is well positioned for that role.

Is Bio-PG enabling next-gen sustainable resins?
Absolutely. As resin manufacturers look to reduce carbon footprint, Bio-PG is increasingly used in bio-resins for coatings, construction, and composite markets.

Will feedstock innovations further accelerate adoption?
Very likely. New pathways using glycerin, sugarcane, and other biomass feedstocks are improving cost efficiency and scalability.

Expert Commentary

“The bio-based propylene glycol market is entering a compelling growth phase,” said Dr. Kavita Desai, Principal Consultant at Introspective Market Research.
“Driven by both regulatory pressure and the genuine demand for sustainable chemistry, Bio-PG is transitioning from a niche green chemical to a mainstream industrial building block. As feedstock technologies mature and production scales, its role in resins, solvents, and personal care will only deepen.”
