Only 5 years ago the European market for DOTP was estimated at a moderate 10kt. Since then a lot happened in the European plasticizer market and the volume did grow a tenfold at least.. The continious pressure on phthalates did move more and more customers to switch to (ortho)phthalate free plasticizers. At the beginning only those customers on the forefront of change did move to DOTP in order to be able offer (ortho)phthalate free products. More customers did follow but interesting enough even more suppliers did.
