Do printed t-shirts and graphics contain phthalates?

Yes, plastisol prints commonly used for graphic t-shirts, logos, and decorative elements on clothing contain PVC (polyvinyl chloride) and phthalate plasticizers. Phthalates make the PVC prints soft and flexible, but they are not chemically bound to the plastic and can migrate out of the print over time. Phthalates are known endocrine disruptors linked to reproductive harm, developmental issues, and hormonal disruption.

The migration of phthalates from prints increases with heat and friction. A printed area on the chest of a t-shirt worn against skin during exercise, or printed sleepwear worn to bed, provides conditions for ongoing low-level phthalate transfer. Children's clothing with large graphic prints is particularly concerning given their higher vulnerability to endocrine-disrupting chemicals.

Alternatives to plastisol printing include water-based inks, discharge printing, and natural dye printing, all of which avoid PVC and phthalates. When buying printed garments, look for brands that specify water-based or phthalate-free inks. GOTS-certified printing uses only approved, non-toxic inks. ONDU favors brands that are transparent about their printing methods and avoid PVC-based graphics.
