    Hydroxyethyl Acrylate (BYIZA) Amabwiriza n'Amahame ngenderwaho
    Hydroxyethyl Acrylate (HEA) iri ku rutonde rw'ibintu byangiza byo mu cyiciro cya 8 muri Katalogu y'Ibinyabutabire Bishobora Gutera Akaga mu Bushinwa ifite umubare wa UN 2929. Umupaka ntarengwa w'ibintu bishobora kwangirika mu kazi ureba ibikubiye muri GBZ 2.1-2019, kandi impuzandengo yemewe y'igihe (PC-TWA) ni 5 mg/m³. Itegeko rya EU REACH risaba ibigo gutanga amakuru y'uburozi kuri iyi miti kandi ribuza kuyikoresha nk'ibikoresho fatizo byo kwisiga. Amabwiriza ya OSHA yo muri Amerika avuga ko ibikoresho byo kwiyuhagira byihutirwa bigomba gushyirwa mu gace k'akazi, kandi intera iri hagati y'aho bikorerwa ntigomba kurenza amasegonda 10. Hydroxyethyl Acrylate (HEA).

    Imiterere ya hydroxyethyl acrylate HEA igaragaza ko ifite polarity runaka. Bitewe n'itandukaniro mu mikorere ya atome zitandukanye muri molekile, ikwirakwizwa ry'umushari ntiringana. Iyi polarity ituma ishobora kuvangwa neza n'ibindi bintu bimwe na bimwe bya polar solvents, nka etanoli n'amazi.
