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".
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]
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 ...
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 ...
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 ...
Several factors must be assessed to determine if a chemical is a suitable substitute including potential hazards, exposure, technical feasibility, and low-budget considerations. [3] After substitutes are proposed, the risks of each substitute are compared to one another and tested until a suitable substitution is found.
