Momwe mungagwiritsire ntchito mankhwala okhala ndi methylparaben mosamala
Pofuna kutsimikizira thanzi ndi chitetezo cha khungu, ogula ayenera kulabadira mfundo zotsatirazi posankha mankhwala okhala ndi methylparaben: Sankhani zazikuluzikulu kapena zodziwika bwino, popeza mankhwalawa nthawi zambiri amakhala ndi zowongolera mozama komanso kafukufuku wamapangidwe. Samalani malangizo ogwiritsira ntchito mankhwalawa kuti mupewe kumwa mopitirira muyeso kapena kugwiritsa ntchito pafupipafupi. Anthu omwe ali ndi khungu losamva ayenera kuganizira za mankhwala ena oteteza chitetezo omwe ali ndi chiopsezo chochepa cha ziwengo, kapena kusankha zosamalira khungu zolembedwa kuti "zopanda zoteteza" kapena "zosungidwa mwachilengedwe".
Mapeto
Zotsatira za methylparaben pakhungu zimadalira kwambiri zomwe zimagwiritsidwa ntchito komanso khungu la munthu. Monga chosungira chomwe chakhazikitsidwa kwanthawi yayitali komanso chogwiritsidwa ntchito kwambiri, Methylparaben ndi yotetezeka kuti igwiritsidwe ntchito pazokhazikika ndipo imathandizira kuteteza zinthu kuti zisaipitsidwe ndi tizilombo tating'onoting'ono.
