PVC PLASTICISERS | ADDITIVES


The search continues for alternative plasticisers


Work to replace DEHP and other phthalate plasticisers is focusing on bio-based sources, writes Chris Saunders. But switching to alternatives is not straightforward


The utility and versatility of flexible PVC has seen the plasticiser landscape undergo a significant transformation in recent times as additive produc- ers try to balance several powerful forces, including regulatory scrutiny, sustainability targets, and demand for higher-performance formulations. According to a report by Research and Markets, the plasticisers market size grew from $98.62bn in 2025 to $106.19bn in 2026 at a compound annual growth rate of 7.7%, with the growth predicted to continue on a similar trajectory until reaching a value of $147.5bn in 2030. This can be attributed to rising demand for next-generation additives, growth in cable and electronics manufacturing, expansion of infrastructure projects, advancements in bio-based plasticisers, and increased adoption in consumer goods.

“Plasticisers [are under scrutiny] because under


certain conditions small amounts can migrate from the flexible PVC compounds, especially considering that some legacy ortho-phthalates were shown to potentially cause adverse health effects, while replacement of any plasticiser is strongly dependent on the uninterrupted supply of cost-effective product grades and demonstrate reduction in health and/or environmental risks,” said author and consult- ant Peter Frenkel, who contributed to The PVC Handbook (2nd edition, Hanser Publications, 2025). Demand arising from replacing DOP (DEHP) plasticiser – which has been banned from use in consumer goods and toys in Europe – has been met with the three primary plasticisers DOTP, DINP, and DIDP. “It requires massive regulatory data development and changes in the supply chain,” he
