Bio-based plasticizers
Bio-based plasticizers replace regulated petroleum-derived phthalates (DEHP, DBP, DINP — under EU REACH SVHC and US EPA scrutiny for endocrine-disrupting effects) with renewable alternatives: epoxidized soybean oil (ESO/ESBO, the leading non-phthalate at ~8.4% of China's plasticizer consumption), isosorbide diesters (from starch/sorbitol), citrate esters (ATBC, food-contact), cardanol-based (from cashew nutshell liquid), and mass-balance bio-attributed resins (ISCC PLUS). Arkema secured ISCC PLUS mass balance certification for its Pasir Gudang Malaysia resins plant (Feb 2025) and brought a $20M Rilsan® Clear transparent polyamide unit online in Singapore (Q1 2026, 45-62% bio-based carbon from castor oil); Lanxess launched a sustainable Mesamoll® version with bio-mass raw materials and presented Vulkanox 4060 (6PPD alternative) at Tire Technology Expo 2026 (Hannover, March). ESO/ESBO dominates on volume (Cargill US, VVF India, Shandong Longkou China), approved for food-contact PVC under FDA 21 CFR 178 and EU REACH.
