DOP/DEHP — Frequently Asked Questions
What are the regulatory restrictions on DOP/DEHP?▾
DOP/DEHP is classified as SVHC (Substance of Very High Concern) under REACH due to reproductive toxicity. It is restricted in toys and childcare articles, food contact materials, and medical devices in the EU and US. Industrial applications without food contact, medical, or children product use are generally not restricted. Contact Texas-Chem for current regulatory guidance and DINP/DOTP alternatives.
What are the best non-restricted alternatives to DOP/DEHP?▾
DINP (diisononyl phthalate) is the most common REACH-compliant phthalate replacement for DOP/DEHP in general-purpose flexible PVC. DOTP (dioctyl terephthalate) is the preferred non-phthalate alternative for food contact, medical, and children product applications. Both are available from Texas-Chem — contact us at 855-TEX-CHEM for formulation guidance.
Can DOP/DEHP be used in food contact PVC?▾
No. DOP/DEHP is not approved for food contact applications in the EU or US. For food contact PVC, use DOTP (dioctyl terephthalate) or citrate ester plasticizers (TBC, TEC) which are approved for food contact.
Is DOP/DEHP still available from Texas-Chem?▾
Yes. Texas-Chem supplies DOP/DEHP for industrial applications where regulatory restrictions do not apply. We also supply DINP and DOTP as non-restricted alternatives. Contact us at 855-TEX-CHEM to discuss your application and the most appropriate plasticizer choice.
