AvobenzoneCAS70356-09-1 – Chofunikira Kwambiri Pankhani Yoteteza Dzuwa ndi Zomwe Zimachitika M'misika

M'zaka zaposachedwapa, chifukwa cha kuwonjezeka kwa chidziwitso cha anthu pankhani yoteteza ku dzuwa, msika wa zinthu zoteteza ku dzuwa wasonyeza chitukuko chochulukirachulukira. Pakati pa zinthu zambiri zoteteza ku dzuwa, avobenzone, monga mankhwala ofunikira kwambiri oteteza ku dzuwa, yatchuka kwambiri.

Avobenzone ndi chinthu chosungunuka ndi mafuta, ndipo mayina ake ogulitsa ndi monga Parsol 1789, Eusolex 9020, Escalol 517, ndi zina zotero. Monga chochokera ku dibenzoylmethane, imatha kuyamwa UVA ya mafunde onse, makamaka yokhala ndi chiŵerengero chachikulu cha kuyamwa kwa UVA yokhala ndi mafunde a 357 nanometers. Chifukwa chake, imagwiritsidwa ntchito kwambiri pazinthu zambiri zomwe zimateteza ku dzuwa, zomwe zimatha kupewa kutentha ndi dzuwa ndikuchepetsa chiopsezo cha khansa ya pakhungu.

Komabe, avobenzone si yopanda kutsutsana. Kafukufuku wochitidwa ndi bungwe la US Food and Drug Administration (FDA) adanenapo kale kuti zosakaniza zomwe zimagwiritsidwa ntchito popanga mafuta oteteza ku dzuwa monga avobenzone zimatha kulowa m'magazi, ndipo kuchuluka kwa mankhwala m'magazi kumaposa malire a chitetezo omwe FDA idapereka, zomwe zimayambitsa nkhawa za anthu ambiri pankhani ya chitetezo cha zinthu zoteteza ku dzuwa. Pakadali pano, FDA idagogomezeranso kuti poganizira kuti mafuta oteteza ku dzuwa atsimikiziridwa kuti ali ndi gawo lofunika kwambiri popewa khansa ya pakhungu ndi zotsatira zina zoyipa za kuwala kwa ultraviolet, ogula sayenera kusiya kugwiritsa ntchito mafuta oteteza ku dzuwa chifukwa cha izi, koma angasankhe zinthu zotetezeka, monga zomwe zili ndi zinthu zoteteza ku dzuwa monga zinc oxide ndi titanium dioxide.

Kuphatikiza apo, pogwiritsira ntchito avobenzone, muyeneranso kuyang'anitsitsa kukhazikika kwake. Muyenera kupewa kukhudzana ndi ayoni achitsulo kuti mupewe kusintha mtundu, ndipo muyenera kugwiritsa ntchito molingana ndi mlingo woyenera kuti muwonetsetse kuti zinthuzo ndi zotetezeka komanso zogwira mtima. Kwa ogula, posankha zinthu zoteteza ku dzuwa zomwe zili ndi avobenzone, ndi bwino kuti muyese kaye khungu pang'ono kuti muwone ngati pali vuto la ziwengo.

Ponseponse, udindo wofunikira wa avobenzone pankhani yoteteza ku dzuwa sunganyalanyazidwe, koma kafukufuku wokhudzana ndi chitetezo ndi kuyang'anira kuyeneranso kulimbikitsidwa nthawi zonse kuti zitsimikizire kuti ogula angagwiritse ntchito zinthu zoteteza ku dzuwa mosamala komanso moyenera kuti asawonongeke ndi kuwala kwa ultraviolet pakhungu. Pakupanga, mabizinesi ayeneranso kuwongolera bwino mtundu, kutsatira miyezo ndi zofunikira, ndikulimbikitsa chitukuko chabwino cha avobenzone pamsika woteteza ku dzuwa.
