What it is
A methylene-bridged bisphenol, one of the common BPA replacement chemicals.
What it does
Used in epoxy resins, coatings, and some food packaging.
Why it’s a concern
Studies consistently show BPF exerts estrogenic activity comparable to BPA. A 2018 review (Eladak et al., Fertility and Sterility) concluded that bisphenol substitutes including BPF are not safer alternatives. Also detected in urine biomonitoring worldwide.
