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.
Among potential substitutes for BPA, phenol-based chemicals closely related to BPA have been identified. The non-extensive list includes bisphenol E (BPE), bisphenols B (BPB), 4-cumylphenol (HPP) and bisphenol F (BPF), with only BPS being currently used as main substitute in thermal paper. [189]
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 ...
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".
The substitution of dangerous chemicals in the workplace is the process of replacing or eliminating the use chemicals that have significant chemical hazards.The goal of the substitution process is to improve occupational health and safety and minimize harmful environmental impacts. [1]
A new report by the Clean Label Project has found that protein powders may contain something other than muscle-building nutrients: lead and cadmium, both of which are toxic.. The national ...
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]
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 ...
