Ho na le phehisano mabapi le hore na methyl 4-hydroxybenzoate methylparaben kapa propylparabens e kotsi maemong a tloaelehileng a sebelisoang tlhokomelong ea 'mele kapa litlolo. Methylparaben le propylparaben li nkuoa li amoheloa ka kakaretso li bolokehile (GRAS) ke USFDA bakeng sa ho boloka lijo le litlolo tsa antibacterial. Methyl 4-hydroxybenzoate Methylparaben e sebelisoa habonolo ke likokoana-hloko tse tloaelehileng tsa mobu, e leng se etsang hore e senyehe ka ho feletseng.

E le ho arabela litabeng tsena, mekhatlo e meng ea tsamaiso le mekhatlo e nkile mehato ea ho thibela tšebeliso ea methyl paraben lihlahisoa tse itseng. Ka mohlala, European Union e fokotsa khatello ea methyl paraben e lumelletsoeng litlolo, 'me bahlahisi ba bang ba khethile ho fetola lihlahisoa tsa bona hore li se ke tsa hlola li e-ba le paraben.
