Additional information

The available acute aquatic toxicity studies on fish, invertebrate and algae were performed on the primary hydrolysis product of BPA-DA (4,4-Bisphenol A Tetra-Acid (BPA TA; CAS 38103-05-8)). The PNECs derived from the PNEC freshwater are thus also on BPA-TA. This is considered acceptable as BPA-TA is the stable primary hydrolysis product of the hydrolytically unstable BPD-DA (DT50 < 24h).

Conclusion on classification

Based on available data, BPA-DA need not be classified for environmental hazards as all LC50 and EC50 values for its primary hydrolysis product (BPA-TA) are above the cut-off value for Classification and Labelling (i.e., 100 mg/L). Furthermore, the LogPow for BPA-TA of -2.2 (pH 7) does not indicate a potential for bioaccumulation.
