What are the different types of bisphenol?

List

Name CAS Reactants
Bisphenol A 80-05-7 Acetone
Bisphenol AP 1571-75-1 Acetophenone
Bisphenol AF 1478-61-1 Hexafluoroacetone
Bisphenol B 77-40-7 Butanone

What is bisphenol F epoxy resin?

Bisphenol F epoxy resins are used in broad applications including coatings, civil engineering, adhesives, electrical insulating materials, and reactive intermediates. In particular, the liquid resins have low viscosity so they excel in workability and moldability which makes them suited to many applications.

Is bisphenol A the same as BPA?

BPA stands for bisphenol A, an industrial chemical that has been used to make certain plastics and resins since the 1950s.

How is bisphenol F made?

The simplest novolac, bisphenol F, is prepared by conducting the reaction of phenol (P) and formaldehyde (F) with a large excess of P under acidic conditions. The mechanism of formation involves initial protonation of methylol glycol, which reacts with phenol at the ortho and para positions (Figure 19).

Is bisphenol S safe?

Bisphenol S is an endocrine disruptor and has comparable health risks to that of Bisphenol A. BPS has been shown to increase the expression of breast cancer carcinogens and the proliferation of positive breast cancer cells [2]. Additionally, BPS exposure has been linked to impaired neural function.

What is bisphenol B used for?

Bisphenol B is currently used as an alternative for some uses of bisphenol A and bisphenol S in a number of countries, particularly in the United States, where it has been registered as an indirect additive used in certain food-contact coatings and polymers.

What is bisphenol F used for?

Bisphenol A (BPA) is a monomer primarily used in the production of polycarbonate plastic and epoxy resins. Bisphenol F (BPF) is apparently the main BPA replacement that is used increasingly. BPF has been detected in canned food, thermal paper receipts, and soft drinks.

Is BPA volatile?

BPA has low volatility in the atmosphere and a low vapor pressure between 5.00 and 5.32 Pascals.

Is bisphenol S safer than bisphenol A?

Bisphenol S is often used as a replacement for Bisphenol A. However, bisphenol S is not necessarily safer to use than Bisphenol A. Studies comparing the risk of BPS vs. BPA in thermal paper receipts yielded similar exposure risks [1] and Million Marker lists them both as chemicals to avoid.

Where is bisphenol F found?

BPF is found in dental materials, such as restorative materials, liners, adhesives, oral prosthetic devices and tissue substitutes.

What replaced BPA?

Bisphenol A (BPA), a chemical used in plastic products, was banned from baby bottles in Canada in 2010 over concerns that it may leach into foods and cause hormone-related side effects. More manufacturers are now using BPS as a replacement in their products and labelling them as BPA-free.
