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 in Dentistry

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 ...

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

Survey of bisphenol A and bisphenol F in canned foods

Food Additives and Contaminants, 2002
Bisphenol A (BPA) and bisphenol F (BPF) have been determined in a range of canned foods. Sixty-two different canned foods were purchased from retail outlets in the UK from January to November 2000 and the contents extracted and analysed by GC-MS for BPA and BPF isomers.

Chlorination and chloramination of bisphenol A, bisphenol F, and bisphenol A diglycidyl ether in drinking water

Water Research, 2015
Bisphenol A (BPA), bisphenol F (BPF), and bisphenol A diglycidyl ether (BADGE) are common components of epoxy coatings used in food packaging and in drinking water distribution systems. Thus, leachates from the epoxy may be exposed to the disinfectants free chlorine (Cl2/HOCl/OCl(-)) and monochloramine (MCA, NH2Cl).

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.

Weak estrogenic transcriptional activities of Bisphenol A and Bisphenol S

Toxicology in Vitro, 2012
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

Cytotoxicity of seven bisphenol analogues compared to bisphenol A and relationships with membrane affinity data [PDF]

Chemosphere, 2018
Bisphenol A (BPA) is a chemical used in numerous industrial applications. Due to its well ascertained toxicity as endocrine disruptor, industries have started to replace it with other bisphenols whose alleged greater safety is scarcely supported by ...

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.

Bisphenol S, bisphenol F, bisphenol a exposure and body composition in US adults

Chemosphere
Bisphenol S (BPS) and bisphenol F (BPF) are increasingly used to replace bisphenol A (BPA), an endocrine-disrupting chemical with putative obesogenic properties; whether and how BPS and BPF affect adiposity in humans remains to be determined. Therefore, we examined the association of BPA, BPS， and BPF with body composition among US adults.
