Bisphenol A (BPA) is a chemical compound primarily used in the manufacturing of various plastics. It is a colourless solid which is soluble in most common organic solvents , but has very poor solubility in water.
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.
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".
Tritan, a copolymer offered by the Eastman Chemical Company since 2007, is a transparent plastic intended to replace polycarbonate, because of health concerns about Bisphenol A (BPA). [1] [2] Tritan is a copolymer made from three monomers: dimethyl terephthalate (DMT), cyclohexanedimethanol (CHDM), and 2,2,4,4-Tetramethyl-1,3-cyclobutanediol ...
On April 18, 2008, Health Canada announced that bisphenol A is "'toxic' to human health". [11] On the same date, Nalgene announced it would phase out production of its Outdoor line of polycarbonate containers containing BPA. [12] Nalgene subsequently adopted Tritan copolyester, a BPA-free copolyester made by Eastman Chemical, as a substitute. [13]
Bisphenol AF is used as a crosslinking agent for certain fluoroelastomers and as a monomer for polyimides, polyamides, polyesters, polycarbonate copolymers and other specialty polymers. Polymers containing Bisphenol AF are useful in specialties such as high-temperature composites and electronic materials.
Ultimately, Alan says the artificial sweetener concerns are probably not a “panic issue” — that is, if you've enjoyed treats with the sugar substitute erythritol in the past, you don’t ...
The GreenScreen for Safer Chemicals is a transparent, open standard for assessing chemical hazard that supports alternatives assessment for toxics use reduction through identifying chemicals of concern and safer alternatives. [1]
