    Hydroxyethyl Acrylate ( .KAHLE) Milawu na Swipimelo
    Hydroxyethyl Acrylate (HEA) yi xaxametiwile tanihi xiaki xa Klasi ya 8 lexi onhaka eka Khathalogi ya Tikhemikhali leti nga ni Khombo ya China leyi nga na nomboro ya UN ya 2929. Mpimo wa ku hlangana na swilo entirhweni wu kombetela eka swiletelo swa GBZ 2.1-2019, naswona nhlayo ya xikarhi leyi pfumeleriwaka leyi pimiweke hi nkarhi (PC-TWA) i 5 mg/m3. Nawumbisi wa EU REACH wu lava leswaku mabindzu ya yisa xitiviso xa datha ya toxicological ya nchumu lowu naswona wu yirisa ku tirhisiwa ka wona tanihi xitirhisiwa xo sasekisa. Mpimo wa OSHA wa le United States wu veka leswaku switirhisiwa swo hlamba swa xihatla swi fanele ku vekiwa endhawini ya ntirho, naswona mpfhuka ku suka laha ku tirhelaka kona a wu fanelanga ku tlula ku famba ka 10 wa tisekoni.Hydroxyethyl Acrylate (HEA).

    Xivumbeko xa hydroxyethyl acrylate HEA xi vona leswaku yina polarity yokarhi. Hikwalaho ka ku hambana ka electronegativity ya ti athomo to hambana eka molekhuli, ku hangalasiwa ka charge a ku ringani. Polarity leyi yipfumelela kuva yi hlangana kahle na ti polar solvents tin’wana, kufana na ethanol na mati.
