The production of 1,3-propanediol (PDO) is on an upward trajectory in 2025, fueled by its applications in polymers, cosmetics, and personal care products. Advancements in bio-based production methods are also contributing to increased output, aligning with the global shift towards sustainable chemicals. PDO prices have exhibited an oscillating trend in 2025. While demand from pharmaceuticals and cosmetics sectors remains strong, fluctuations in feedstock prices have introduced variability. The market anticipates continued price adjustments as supply chains stabilize.
