Concerns about the health effects of BPA have led some manufacturers replacing it with other bisphenols, such as bisphenol S and bisphenol F. These are produced in a similar manner to BPA, by replacing acetone with other ketones, which undergo analogous condensation reactions. [7] Thus, in bisphenol F, the F signifies formaldehyde. Health ...
Exceptions include bisphenol S, P, and M. "Bisphenol" is a common name; the letter following denotes the variant, which depends on the additional substituents. Bisphenol A is the most popular representative of the group, with millions of metric tons produced globally in the past decade, often simply called "bisphenol".
Epoxy resins derived from bisphenol A are used as coatings on the inside of almost all food and beverage cans; [13] however, due to BPA health concerns, in Japan epoxy coating was mostly replaced by PET film. [14] Bisphenol A is a preferred color developer in carbonless copy paper and thermal point of sale receipt paper.
Bisphenol A diglycidyl ether slowly hydrolyzes to 2,2-bis[4(2,3-dihydroxypropoxy)phenyl)propane (bis-HPPP). Similarly, DGEBA reacts with acrylic acid to give vinyl ester resins . The reaction results in opening of the epoxide ring, generating unsaturated esters at each terminus of the molecule.

A freshwater aquatic food web. The blue arrows show a complete food chain (algae → daphnia → gizzard shad → largemouth bass → great blue heron). A food web is the natural interconnection of food chains and a graphical representation of what-eats-what in an ecological community.
A food safety expert weighs in on flour bugs, also known as weevils, that can infest your pantry after one TikToker found her flour infested with the crawlers.
