OECD Requests Input on Draft Guidance for Toxicokinetics Testing of Nanoparticles

The OECD is conducting a public consultation on draft guidance for adapting toxicokinetics studies to nano- and microparticles. The consultation closes November 11, 2025.

The guidance addresses design considerations including dosing, formulation, and kinetic sampling to ensure toxicokinetics data accurately represent particulate materials. The document will support harmonized human health assessments for nano-enabled products across OECD member countries.
