1,6-Hexanediol Diglycidylether (HDDGE) was evaluated in an O.E.C.D. Testing Guideline 209 study with GLP compliance.  

Key value for chemical safety assessment

Additional information

The estimated IC50 value for 1,6 -Hexanediol Diglycidylether (HDDGE) to activated sludge was > 100 mg/L. Therefore, HDDGE is considered to be non-toxic to activated sludge bacteria. Based on E.C.H.A. guidance a total Assessment Factor of 100 -fold is applied to this IC50 value resulting in a PNEC microorganisma of > 1.0 mg/L.
