Polycarbonate is commonly used in eye protection, as well as in other projectile-resistant viewing and lighting applications that would normally indicate the use of glass, but require much higher impact-resistance. Polycarbonate lenses also protect the eye from UV light.
Other names Bis(4-hydroxyphenyl)cyclohexane. Identifiers CAS Number. 843-55-0; 688035-61-2 (hydrate) ... It is a precursor to specialty polycarbonate plastics. [1]

Glucotropaeolin (the precursor to benzyl isothiocyanate) Gluconasturtiin (the precursor to phenethyl isothiocyanate) Glucoraphanin (the precursor to sulforaphane) brassicas: broccoli, cauliflower, brussels sprouts, cabbages.
Polycarbonate drink containers are also a source of exposure, although most disposable drinks bottles are actually made of PET, which contains no BPA. Among the non-food sources, exposure routes include through dust, [10] thermal paper, [20] clothing, [19] dental materials, [71] and medical devices. [17]
The study's findings include: 1) evidence of BPA in participants' urine decreased by 50% to 70% during the period of eating fresh foods; and 2) participants' reports of their food practices suggested that consumption of canned foods and beverages and restaurant meals were the most likely sources of exposure to BPA in their usual diets.
Polycarbonate polyols are more expensive than other polyols and are thus used in more demanding applications. [31] [32] They have been used to make an isophorone diisocyanate based prepolymer which is then used in glass coatings. [33] They may be used in reactive hotmelt adhesives. [34] All polyols may be used to produce polyurethane prepolymers.
The FDA’s recent ban on Red Dye No. 3, set to take effect by 2027 for foods and 2028 for drugs, marks a significant step in addressing safety concerns over artificial food dyes in the U.S. food ...
Phytoestrogen content varies in different foods, and may vary significantly within the same group of foods (e.g. soy beverages, tofu) depending on processing mechanisms and type of soybean used. Legumes (in particular soybeans), whole grain cereals, and some seeds are high in phytoestrogens. [citation needed]
