Are NICU babies getting too much DEHP from feeding tubes?
Yes. Premature babies fed through plastic tubing absorb high doses of DEHP and its swap-ins.
What's actually in it
DEHP is the standard softener in flexible PVC medical tubing. It makes the tubing bendy enough for IVs, blood transfusions, and feeding lines. The trouble: DEHP doesn't bond to the PVC, so it leaches into whatever fluid runs through the tube.
Premature babies in the NICU often get fed through these tubes for weeks or months, at the most sensitive moment in their development.
What the research says
A 2025 study in Environ Sci Technol measured DEHP and "alternative plasticizers" in enteral nutrition delivered through PVC tubing. Babies received doses high above safety limits set for their tiny weight. The replacements (DINP, DINCH, DEHTP) showed up too, with their own concerns.
Many hospitals have begun switching to DEHP-free medical-grade tubing, but availability varies.
If your baby is in the NICU, ask the care team if the unit uses DEHP-free feeding lines. Some U.S. hospitals already do. For at-home pumping, choose silicone or polypropylene tubing instead of clear PVC. The Children's Hospital Association keeps a list of DEHP-free purchasing options.
