# 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. Source: https://en.bioecon.ru/technology/bio-based-plasticizers/ Updated: 2026-08-18 ## Overview and value chain Markers: [EC: EU REACH (phthalate substitution, SVHC) / FDA food-contact (21 CFR 178) / EPA TSCA chemical safety | OECD: Industrial biotechnology | Regulator: REACH (EU), FDA (USA), EPA (USA)] Bio-based plasticizers replace petroleum-derived phthalate esters — DEHP, DBP, DINP, DIDP, the workhorse PVC plasticizers now under EU REACH Substances of Very High Concern (SVHC) authorisation and US EPA TSCA scrutiny for endocrine-disrupting and reproductive-toxicity effects — with renewable molecules whose feedstocks are agricultural (soybean oil, linseed oil, castor oil, starch, cashew nutshell liquid, citrus). Four dominant product families emerged by 2026: **epoxidized soybean oil (ESO/ESBO)**, the volume leader at ~8.4% of China's plasticizer consumption and the most widely deployed non-phthalate globally, used as a co-plasticizer and heat stabiliser in PVC wire/cable, food-contact packaging, and medical devices; **isosorbide diesters** (from starch → sorbitol → isosorbide), high-performance specialty plasticizers and monomers for polycarbonates and epoxy resins driven by BPA phase-out regulation; **citrate esters** (acetyl tributyl citrate ATBC, triethyl citrate TEC), food-contact-safe and used in medical PVC and children's toys; and **mass-balance bio-attributed resins** (ISCC PLUS certified), where Arkema's Pasir Gudang Malaysia acrylic + liquid polyester resins plant (ISCC PLUS certified February 28, 2025) and Lanxess's sustainable Mesamoll® (bio-mass raw materials) represent the certified-renewable-carbon approach. Arkema's Rilsan® Clear transparent polyamide unit in Singapore ($20 million investment, operational Q1 2026, tripled global capacity, 45-62% bio-based carbon from castor-oil-derived polyamide 11) and Lanxess's Vulkanox 4060 (a sustainable alternative to the 6PPD tire antioxidant, REACH registration for volumes exceeding 1,000 tons, commercial production from mid-2026, unveiled at Tire Technology Expo 2026 in Hannover March 3-5) anchor the 2026 bio-attributed additives pipeline. Soybean oil dominates the ESO raw material mix (~58.6% of 2025 market share) and plasticizers lead application consumption (~41.9% of 2025 revenue share), with food and beverage packaging the dominant end-use as ESBO serves as both PVC gasket plasticizer and heat stabiliser in metal can closures. The key directions of bio-based plasticizers are: 1. **Epoxidized soybean oil (ESO/ESBO):** the volume leader among non-phthalate plasticizers — produced by epoxidising soybean oil with hydrogen peroxide under acid catalysis (converting double bonds to epoxy groups), used as a co-plasticizer and heat stabiliser in PVC wire/cable, food-contact packaging, medical devices, coatings, synthetic rubber, and biodegradable TPS/PLA composites; approved for food-contact under FDA 21 CFR 178 and EU REACH; major producers Cargill (US), VVF (India), Shandong Longkou (China), and Equilex (Europe food-grade + technical-grade). 2. **Isosorbide diesters (from starch → sorbitol → isosorbide):** high-performance bio-based monomers and plasticizers driving BPA phase-out in polycarbonates and epoxy resins — Roquette's POLYSORB® isosorbide (LP, PS, A grades, high-purity bio-based monomer for performance materials) is the dominant feedstock, with Arkema's castor-oil-derived polyamide 11 (Rilsan® Clear, 45-62% bio-based carbon) and mass-balance resins consuming the downstream volumes. 3. **Mass-balance bio-attributed resins (ISCC PLUS certification):** Arkema's ISCC PLUS certified Pasir Gudang Malaysia facility (acrylic + liquid polyester resins, certified February 28, 2025) and global mass balance roadmap — joining prior certifications in the US, Europe, and China — to progressively offer bio-attributed specialty resins and additives (high solids, waterborne, UV/LED/EB, polyester powders) with renewable content; Lanxess's sustainable Mesamoll® with bio-mass raw materials follows the same certified-renewable-carbon model. 4. **Sustainable rubber and tire additives (pelargonic acid, 6PPD alternatives):** Lanxess Vulkanox 4060 (N,N'-dicyclohexyl-1,4-phenylenediamine, CCPD) — a sustainable alternative to the 6PPD antioxidant under regulatory pressure in the US and EU; Aflux SD silica processing agent from sustainable raw materials (SVHC-free); Neolone PH Max preservative combining phenoxyethanol with natural pelargonic acid from sunflower oil — both presented at Tire Technology Expo 2026 (Hannover, March 3-5) and in-cosmetics Global 2026 (Paris, April 14-16). ### Sectoral value chain ``` [soybean / castor / starch / cashew nutshell feedstock] ──> [oil extraction / sugar refining] │ (crude oil / glucose) │ ▼ [finished bio-based plasticizer drum / IBC] <─── [compounding & formulation] <─── [purification & distillation] <─── [chemical conversion (epoxidation / esterification / hydrogenation)] ``` ### Value chain levels | Level | Description | Key inputs/outputs | |:---|:---|:---| | **Feedstock cultivation & extraction** | soybean oil (Eso dominant feedstock, ~58.6% of 2025 market), castor oil (Arkema polyamide 11), starch/sorbitol (Roquette isosorbide), cashew nutshell liquid (cardanol), citrus (citrate esters), sunflower oil (pelargonic acid) | **In:** agricultural feedstock.

**Out:** recycled polymer or compost. | Cross-cutting technologies of the sector: - **Epoxidised soybean oil epoxidation (Epoxidized Soybean Oil ESBO Epoxidation):** the dominant bio-based plasticizer conversion route — soybean oil + hydrogen peroxide under acid catalysis, solvent-free processes now dominant over solvent-based for green-chemistry reasons; epoxy values ≥6.0 for high-quality grades; double-bond-to-epoxide conversion significantly improves thermal stability, oxidation resistance, and PVC compatibility. - **Isosorbide diester from starch/sorbitol (Isosorbide Diester from Starch Sorbitol):** Roquette POLYSORB® isosorbide (LP liquid plasticizer grade, PS and A polymer grades) — high-purity bio-based monomer from starch → sorbitol → isosorbide dehydration, used as both a plasticizer and a high-performance monomer for polycarbonates and epoxy resins driving BPA phase-out. - **Mass balance ISCC PLUS bio-attributed resins (Mass Balance ISCC PLUS Bio-Attributed Resins):** Arkema's certified chain-of-custody approach — substituting renewable for fossil naphtha at the cracker feed, then allocating the renewable carbon to specific products via ISCC PLUS mass balance; the Pasir Gudang Malaysia certification (February 2025) joins prior certifications in the US, Europe, and China, enabling Arkema to offer bio-attributed acrylic and liquid polyester resins with up to 100% biobased content. --- ## US The US hosts the world's largest ESO producer (Cargill) and is the regulatory driver of 6PPD and phthalate substitution via EPA TSCA and FDA 21 CFR 178 food-contact approvals. ### Cargill ESO leadership, FDA food-contact pathway, EPA phthalate scrutiny - **Cargill (Minneapolis, MN):** the largest US producer of epoxidized soybean oil (ESO/ESBO) — the dominant non-phthalate plasticizer globally at ~8.4% of China's plasticizer consumption and the leading bio-based additive for PVC processing in North America; ESO serves the food-contact packaging sector (FDA 21 CFR 178 approval for can-end gaskets and cling film), wire and cable compounds, medical devices (IV bags, tubing), and biodegradable TPS/PLA composites; Cargill's vertical integration from soybean crushing to ESO epoxidation anchors the US bio-based plasticizer supply chain. - **FDA 21 CFR 178 food-contact pathway:** ESBO is cleared under FDA 21 CFR 178.3740 (plasticizers in polymeric substances) for food-contact PVC gaskets and cling films; acetyl tributyl citrate (ATBC) is cleared under 21 CFR 178.3790 and 21 CFR 175.300 for food-contact and resinous polymeric coatings; both pathways are the regulatory template every new bio-based plasticizer must qualify under to access the food-packaging end-use. - **EPA TSCA phthalate scrutiny:** DEHP, DINP, and DBP are on the EPA TSCA Work Plan for Chemical Assessments (medium-high concern for reproductive toxicity); the EPA's 2024-2026 risk evaluations under amended TSCA (2016 Frank R. Lautenberg Act) drive the substitution demand that ESO and ATBC fill — making FDA food-contact clearance and EPA TSCA risk evaluation the two regulatory levers shaping US bio-based plasticizer adoption. --- ## CN China is both the world's largest ESO producer (Shandong Longkou and the broader Shandong/Jiangsu chemical corridor) and the largest plasticizer consumer market, with ~8.4% of 2020 plasticizer consumption already in epoxy (ESO) grades — the highest non-phthalate share of any major economy. ### Shandong Longkou ESO production, China plasticizer market structure, REACH-driven exports - **Shandong Longkou (Shandong province):** Chinese ESO producer cluster centred on the Shandong and Jiangsu chemical corridor — product listings (环氧大豆油, CAS 8013-07-8, EINECS 232-391-0) specify epoxy value ≥6.0, light-yellow viscous oil, food-grade and technical-grade specifications; the cluster supplies both the domestic PVC wire/cable and food-packaging market and the EU REACH-driven export demand for non-phthalate plasticizers. - **Jiaao Enprotech (JIAAO ENPROTECH, China):** a professional eco-friendly plasticizer manufacturer whose 2026 ESO technical literature describes solvent-free epoxidation processes now dominant over solvent-based methods, with epoxy plasticizers at ~8.4% of China's 2020 plasticizer consumption (the second-largest category among non-phthalate options) — positioning China as the highest-non-phthalate-share major economy on volume basis. - **REACH-driven export demand:** EU REACH SVHC authorisation on DEHP, DBP, and BBP (and the broader phthalate restriction trend) drives Chinese ESO and epoxy plasticizer exports to European PVC compounders and food-packaging manufacturers; the Made in China + REACH-compliant export combination anchors the Shandong/Jiangsu ESO cluster's 2025-2026 growth trajectory. --- ## EU The EU hosts the leading mass-balance bio-attributed resins platform (Arkema, France) and the leading sustainable rubber/tire additives pipeline (Lanxess, Germany), with EU REACH as the primary regulatory driver of phthalate substitution and SVHC authorisation. ### Arkema mass balance ISCC PLUS, Lanxess sustainable Mesamoll + Vulkanox 4060 - **Arkema (Puteaux, France, Euronext Paris: AKE, 2023 sales €9.5 billion, ~151 production sites, founded 2006):** ISCC PLUS mass balance certification for its Pasir Gudang Malaysia acrylic and liquid polyester resins (OFPE) production site (certified February 28, 2025) — joining prior certifications in the US, Europe, and China, and supporting customers across coatings, adhesives for new energies, green mobility, and infrastructure with bio-attributed resins containing up to 100% biobased content; the $20 million Rilsan® Clear transparent polyamide unit in Singapore (operational Q1 2026) tripled global capacity for the flagship Rilsan®Clear G850 and G820 grades containing 45% and 62% bio-based carbon from castor-oil-derived polyamide 11; castor oil platform spans 100% bio-based polyamides, advanced oleochemicals, polyamide additives (60-100% renewable content as rheology modifiers), and instant adhesives (60% bio-based content); Laurent Tellier appointed Chief Operating Officer effective July 1, 2026. - **Lanxess (Cologne, Germany, XETRA:LXS, founded 2004):** the sustainable version of Mesamoll® plasticizer (bio-mass raw materials) launched to market, supported by Products Carbon Footprint certificates and renewable-energy/sustainable-raw-material sourcing; Stabaxol® P 110 hydrolysis stabiliser for bio-based polyesters (PLA) improves hydrolytic stability several-fold at lower dosage; Vulkanox 4060 (N,N'-dicyclohexyl-1,4-phenylenediamine, CCPD) — sustainable alternative to the 6PPD tire antioxidant under regulatory pressure — with commercial production from mid-2026 and REACH registration for volumes exceeding 1,000 tons; Aflux SD silica processing agent from sustainable raw materials (SVHC-free, reduces rolling resistance/wear/wet-grip Payne effect); Neolone PH Max preservative combining phenoxyethanol with natural pelargonic acid from sunflower oil (in-cosmetics Global 2026, Paris, April 14-16); Tire Technology Expo 2026 (Hannover, March 3-5, 2026). - **Qualitative context (BASF, Roquette):** BASF's Hexamoll DINCH and biomass-balanced additives portfolio for architectural coatings, plus Ecoflex® biomass balance, represent the broad-chemicals approach to certified renewable carbon; Roquette Frères' POLYSORB® isosorbide (LP, PS, A grades) is the dominant high-purity bio-based monomer feedstock from starch → sorbitol → isosorbide, consumed downstream by Arkema and other performance-polymer producers — both named as EU industry context rather than tabled because neither surfaced a 2026 plasticizer-specific commercial event on the scale of the Arkema ISCC PLUS or Lanxess Vulkanox 4060 milestones. --- ## Leading companies and research institutes | Company / Institute | Country | Key products / platforms | Tech features | Status 2026 | |:---|:---|:---|:---|:---| | **Cargill** | 🇺🇸 USA | *Epoxidized soybean oil (ESO/ESBO) for PVC, food-contact, medical* | Largest US ESO producer;

epoxy value ≥6.0; REACH-compliant EU export; ~8.4% of China plasticizer consumption in epoxy grades | commercial | --- ## Tech stack and innovations The bio-based plasticizer stack rests on three orthogonal conversion routes — epoxidation of plant oils, starch-to-isosorbide dehydration, and mass-balance fossil-naphtha substitution — plus the emerging rubber/tire additives substitution (6PPD, pelargonic acid) that extends the bio-based additives platform beyond PVC into the tire industry. 1. **Epoxidised soybean oil (ESO/ESBO) epoxidation:** - The dominant non-phthalate plasticizer conversion route — soybean oil + hydrogen peroxide under acid catalysis, with solvent-free processes now dominant over solvent-based methods for green-chemistry reasons; the C=C double bonds in soybean oil's triglyceride molecules are converted to epoxy groups, significantly improving thermal stability, oxidation resistance, and PVC compatibility. - High-quality grades achieve epoxy values ≥6.0; the resulting ESBO is approved for food-contact PVC (FDA 21 CFR 178.3740, EU 10/2011) and used at typical loadings of 3-10 phr as a co-plasticizer and heat stabiliser alongside primary plasticizers in wire/cable, food-packaging gaskets, medical IV bags, and biodegradable TPS/PLA composites. 2. **Isosorbide diester from starch → sorbitol → isosorbide:** - Roquette's POLYSORB® isosorbide platform dehydrates sorbitol (itself hydrogenated from starch-derived glucose) to isosorbide — a rigid bicyclic diol that imparts high thermal stability, transparency, and potential biodegradability to polycarbonates, epoxy resins, polyester polyols, and polyurethanes; the LP grade is a liquid plasticizer, the PS and A grades are polymer-grade monomers. - The platform's growth is fundamentally linked to BPA phase-out regulation — isosorbide partially replaces bisphenol A in polycarbonates and epoxy resins for automotive interiors, electronics, packaging, and medical devices, with the IndexBox 2026 market report projecting transition from premium specialty to mainstream category by 2035. 3. **Mass balance ISCC PLUS bio-attributed resins:** - Arkema's mass balance approach substitutes renewable for fossil feedstock at the cracker inlet, then allocates the renewable carbon to specific products via ISCC PLUS chain-of-custody certification — enabling bio-attributed acrylic and liquid polyester resins with up to 100% biobased content without rebuilding the production infrastructure. - The Pasir Gudang Malaysia certification (February 2025) joins prior certifications in the US, Europe, and China, and supports customers across coatings, adhesives for new energies, green mobility, and infrastructure efficiency — the mass balance route is the most scalable path to bio-attributed specialty chemicals because it inherits existing cracker and resin plant capacity rather than requiring greenfield bio-refinery CapEx. --- ## Value chains and production pipelines ### Industrial pipeline of bio-based plasticizers (EU REACH / FDA 21 CFR 178 / EPA TSCA) ``` ┌───────────────────────────┐ ┌───────────────────────────┐ │ 1.
