Joint Investigation Group of Four Departments Issues Findings on the Formamide Issue in Infant Diapers

The Paper reproduces an October 15 notice from a four-agency Chinese investigation into concerns about formamide in infant diapers. According to the notice, investigators sampled 368 finished-product batches covering 180 brands and 168 domestic manufacturers, including contract manufacturers; the commissioned tests did not detect formamide.

The authorities also reported problems with some earlier testing, including unclear identification criteria, missing control or parallel tests, and deleted original data. They said retesting of blood samples likewise did not detect formamide and that the investigation had not found related health harm from infant diapers. These are the stated findings of the official investigation and the samples it describes, rather than a universal assurance about every product or every possible health risk.
