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 has an EC50/LC50 value of 100 mg/L and is not readily biodegradable.

Conclusion on classification

The test substance, 4,4'-Isopropylidenediphenol, oligomeric reaction products with 1-chloro-2,3-epoxypropane, reaction products with fatty acids, C18-unsatd., dimers, has a measured EC50/LC50 value of 100 mg/L for both fish (rainbow trout) and Daphnia. Therefore, since the test substance is not readily biodegradable, it may cause long-term adverse effects on aquatic life.
