TL;DR
By using two highly standardised transactivation assays, it is demonstrated that the estrogenic activity of Bisphenol A and Bispenol S is of a comparable potency.
Abstract
In 2011, the European Commission has restricted the use of Bisphenol A in plastic infant feeding bottles. In a response to this restriction, Bisphenol S is now often used as a component of plastic substitutes for the production of babybottles. One of the major concerns leading to the restriction of Bisphenol A was its weak estrogenic activity. By using two highly standardised transactivation assays, we could demonstrate that the estrogenic activity of Bisphenol A and Bisphenol S is of a comparable potency. Furthermore, some insights about the structure-activity relationships of these two chemicals and their metabolites could be gained from in silico predictions of their relative estrogen receptor-binding affinities and their liver phase-I biotransformation.

The results suggest that the 4-hydroxyl group of the A- phenyl ring and the B-phenyl ring of BPA derivatives are required for these hormonal activities, and substituents at the 3,5-positions of the phenyl rings and the bridging alkyl moiety markedly influence the activities.

Dietary bisphenol A was evaluated in a mouse two-generation study and there were no treatment-related effects and no evidence of nonmonotonic dose-response curves for any parameter, therefore, BPA is not considered a selective reproductive or developmental toxicant in mice.

Overall, based on this comprehensive evaluation of recent toxicity data, the Panel on food contact materials, enzymes, flavourings and processing aids (CEF) concluded that no new study could be identified, which would call for a revision of the current Tolerable Daily Intake (TDI).

Hydrophobic monomer bisphenol A dimethacrylate (BPA-DMA), which is also estrogenic, was found to be included in these estrogenic sealants in an amount greater than the minimum concentration to show estrogenicity, which suggests that the estrogenicity of the two proprietary sealants was associated with BPA- DMA rather than with B PA.
