Description of key information

The test substance, 4,4'-Isopropylidenediphenol, oligomeric reaction products with 1-chloro-2,3-epoxypropane, reaction products with fatty acids, C18-unsatd., dimers was accessed for toxic potential to sewage sludge in an O.E.C.D. test guideline 209 study.

Key value for chemical safety assessment

EC50 for microorganisms:
1 000 mg/L

Additional information

The test substance, 4,4'-Isopropylidenediphenol, oligomeric reaction products with 1-chloro-2,3-epoxypropane, reaction products with fatty acids, C18-unsatd., dimers was reported to have an IC50 value of > 1000 mg/L for activated sewage sludge in an O.E.C.D. test guideline 209 studies. Therefore, the test substance is not anticipated to have an adverse effect upon sewage sludge in waste-water treatment plants.
