Kufotokozera kwa Methylparaben
Methylparaben, yokhala ndi nambala yolembetsera ya CAS 99-76-3, imadziwikanso kuti Methyl p-hydroxybenzoate; 4-(Methoxycarbonyl)phenol. Ili m'gulu la zinthu zomwe zimapangidwa ndi Wopanga; Zipangizo Zogwira Ntchito; Zonunkhira. Nambala yake ya EINECS ndi 202-785-7. Fomula ya molekyulu ya mankhwala awa ndi C8H8O3ndipo kulemera kwa mamolekyu ndi 152.15. Komanso, dzina lake lokhazikika ndi Benzoic acid, 4-hydroxy-, methyl ester. Methylparaben imayamwa mosavuta kuchokera m'mimba kapena kudzera pakhungu. Imasungunuka kukhala p-hydroxybenzoic acid ndipo imatulutsidwa mwachangu popanda kusonkhana m'thupi. Mwa anthu omwe ali ndi khungu labwinobwino, methylparaben siikwiyitsa komanso siimayambitsa kukwiya; komabe, pali malipoti okhudza ziwengo ku parabens zomwe zadyedwa. Imapezeka m'zinthu zambiri zodziwika bwino pakhungu/nkhope.

Kugwiritsa Ntchito Methylparaben: Methylparaben imadziwika kuti imachepetsa kukula kwa Drosophila m'magawo a mphutsi ndi agalu. Ndi mankhwala opha tizilombo toyambitsa matenda omwe amagwiritsidwa ntchito kwambiri ngati chosungira chakudya, mankhwala, ndi zodzoladzola. Mycocten, ndipo nthawi zambiri imagwiritsidwa ntchito ngati choletsa bowa mu Drosophila food media. Methylparaben ndi mankhwala opha bowa omwe nthawi zambiri amagwiritsidwa ntchito mu ma gels a tsitsi. Mankhwalawa nthawi zambiri amapezeka mu carpules ya mankhwala oletsa ululu am'deralo, omwe amagwira ntchito ngati choletsa bacteriostatic komanso chosungira. Methylparaben (yomwe imatchedwanso Nipigin M, Tegosept, ndi Mycocten) imagwiritsidwa ntchito kwambiri ngati fungicide mu Drosophila food media. Kugwiritsa ntchito methylparaben kumadziwika kuti kumachepetsa kukula kwa Drosophila m'magawo a mphutsi ndi agalu.
Methylparaben ndi yoopsa ikapumira, ikakhudzana ndi khungu komanso ikamezedwa. Imakwiyitsa maso, ziwalo zopumira komanso khungu. Mukaigwiritsa ntchito, valani zovala zoyenera zodzitetezera, pewani kukhudzana ndi khungu ndi maso. Ngati ikakhudzana ndi maso, muzimutsuka nthawi yomweyo ndi madzi ambiri ndikufunsani upangiri kwa dokotala.
