Polyvinylpyrrolidone (PVP), also commonly called polyvidone or povidone, is a water-soluble polymer compound made from the monomer N-vinylpyrrolidone. [1] PVP is available in a range of molecular weights and related viscosities, and can be selected according to the desired application properties.
Povidone-iodine is a chemical complex of the polymer povidone (polyvinylpyrrolidone, PVP) and triiodide (I − 3). [24] It is synthesized by mixing the PVP polymer with iodine (I 2), allowing the two to react. [25] It is soluble in cold and mild-warm water, ethyl alcohol, isopropyl alcohol, polyethylene glycol, and glycerol.
Per- and polyfluoroalkyl substances (also PFAS, [1] PFASs, [2] and sometimes referred to as "forever chemicals" [3] [4]) are a group of synthetic organofluorine chemical compounds that have multiple fluorine atoms attached to an alkyl chain; there are 7 million such chemicals according to PubChem. [5]
α-Pyrrolidinopentiophenone (α-PVP), also known as α-pyrrolidinovalerophenone, O-2387, β-keto-prolintane, prolintanone, [2] [3] or desmethylpyrovalerone, is a synthetic stimulant of the cathinone class developed in the 1960s that has been sold as a designer drug and often consumed for recreational reasons.
J.D. Irving Limited (JDI) traces its roots to a sawmill operated in Bouctouche, New Brunswick by its namesake, James Dergavel Irving. [1] J.D. Irving's operations were passed to his children, one of whom, Kenneth Colin Irving, assumed majority ownership and used JDI to expand into pulp and paper and other forestry-related businesses between the 1920s and 1940s.
4-Chloro-α-pyrrolidinovalerophenone (also known as 4-chloro-α-pyrrolidinopentiophenone, 4-chloro-α-PVP, 4Cl-PVP, or 4C-PVP, or alpha-PVP, or flakka) is an emerging recreational designer drug of the pyrrolidinophenone class, similar in structure to α-pyrrolidinopentiophenone (α-PVP). [1]
Bath salts usually contain cathinones, typically methylenedioxypyrovalerone (MDPV, also known as "monkey dust", although this term can refer to MDPHP as well [8]), methylone or mephedrone; however, the chemical composition varies widely [6] [9] and products labeled with the same name may also contain derivatives of pyrovalerone or pipradrol.
On January 31, 2009, the Government of Canada's final assessment concluded that exposure to vinyl acetate is not harmful to human health. [13] This decision under the Canadian Environmental Protection Act (CEPA) was based on new information received during the public comment period, as well as more recent information from the risk assessment ...
