After several years of work, the Watchfrog Laboratory validates a new OECD method for identifying endocrine disruptors on the estrogenic axis (TG No. 252). This announcement complements the previous TG XETA No. 248 and TG RADAR No. 251 approved by the OECD in 2019 and 2022. Industries in all OECD member countries can use those tests results in regulatory product registrations.
