Price Volatility of Vegetable Oils

Soybean oil prices increased significantly from January 2024 to December 2025, driven by a drought in Argentina and Brazil's adoption of B15 biodiesel blends. Castor oil prices rose sharply after India restricted exports, putting pressure on formulators in Europe and North America. Palm oil prices experienced fluctuations due to changes in export levies by Indonesia, making glycerol esters more expensive. Small producers operating on short-term spot contracts faced margin compressions and passed on these increased costs, resulting in bio-alternatives being priced higher than phthalates. Unless there's an improvement in feedstock hedging, these cost surges are projected to impact the forecast CAGR negatively.

Performance Gap in High-temperature Applications

Above 120 °C, citrate esters volatilize, leading to stiffness in under-hood harnesses, as per SAE J1128 testing^{[2]SAE International, “J1128 Standard for Automotive Wire,” sae.org} . ESBO-plasticized PVC experiences significant elongation loss at elevated temperatures compared to DINP. OEMs, including Volkswagen, adopt dual specifications: permitting bio-plasticizers in cabin wiring but mandating trimellitates for powertrain areas. The absence of bio-specific pass/fail criteria in IEC 60811-404 introduces certification ambiguity. This technical limitation slows rapid substitutions in high-heat zones and reduces growth.
