Estrogenicity of bisphenol A and bisphenol A dimethacrylate in vitro

Journal of Biomedical Materials Research, 1999
Although pit and fissure sealants have been utilized extensively in dentistry as a way of preventing occlusal caries, results described by Olea et al. (1996) raised concerns about the safety of sealants and other resin-based dental materials due to the reported presence of bisphenol A (BPA) and its dimethacrylate ester (BPA-DM). Although the release of

Alkenylidene bisphenols, a new class of bisphenol bactericide

Journal of Medicinal Chemistry, 1979
Alkenylidene bisphenols are prepared by condensation of an appropriate phenol with a haloacetaldehyde, followed by base-induced elimination, or by condensation of the corresponding aryl methyl ether, elimination, and deprotection of the phenol with boron tribromide. The resulting compounds may be further elaborated by reactions on the aromatic nucleus.

Bisphenol A in Dentistry.

The European journal of prosthodontics and restorative dentistry, 2020
Bisphenol-A, an organic synthetic compound, has been present in many consumer plastic products and food packaging since the 1960s. Nowadays, Bisphenol-A is widely used in the field of dentistry for the manufacturing of resin materials. Several studies have suggested that Bisphenol-A may cause adverse health effects due to its ability to act as an ...

The pigmentation interference of bisphenol F and bisphenol A

Environmental Pollution, 2020
Bisphenol A (BPA) and bisphenol F (BPF) are widely distributed in the environment and daily consumptions, leading to exposure toward human and environmental animals. The potential risk of bisphenol analogs on pigment and skin health is not well documented.

Bisphenol‐A‐polycarbonate‐bisphenol‐A‐polysulfone block copolymers

Polymer Engineering & Science, 1977
AbstractMultiblock , block copolymers of bisphenol‐A‐polycarbon ate and bisphenol‐A‐polysulfone were prepared by three different synthesis routes. The in situ method consisted of forming the polycarbonate block in the presence of hydroxyl terminated polysulfone oligorner.

Sensitivity to Bisphenol A

Archives of Dermatology, 1960
Epoxy resin is a condensation product of epichlorohydrin and Bisphenol A. The latter was suspected to be the sensitizing structure in this resin, but final proof had to await the finding of another suitable subject. 1 In spite of an alertness for epoxy sensitization, only two cases have been seen since 1957.
