The plasticizing chemicals are largely the monomers of the polymers we consider plastics. So they’re not an additive but rather a fundamental monomer in these polymer chains. Eg bpa is per se the fundamental monomer of vanilla polycarbonate, along with vanilla epoxy chemistry. The frustrating thing is that eg the bpa substitutes that are used in alternative polymer chemistry to create polycarbonate analogues are chemically similar to bpa and have very high probability of demonstrating similar health issues once relevant science / public health research is supported. Though basically every single plastic monomer has been demonstrated itself to be estrogenic in vitro studies. Even when limited to concentrations that would come from leaching via water or alcohols.
