Chidule
Octinoxate, yotchedwanso Octyl methoxycinnamate kapena OMC, ndi mankhwala omwe amagwiritsidwa ntchito kwambiri popanga zodzikongoletsera ndi khungu padziko lonse lapansi. Koma kodi izi zikutanthauza kuti ndi zotetezeka kwa inu ndi banja lanu? Mayankho anali osakanikirana.
Pakadali pano, palibe umboni wambiri wosonyeza kuti mankhwalawa amawononga kwambiri anthu. Komabe, zawonetsedwa kuti zitha kuvulaza nyama ndi chilengedwe.
Ngakhale maphunziro owonjezeka akuchitika, maphunziro a nthawi yayitali sanakwaniritsidwe momwe octinoxate ingakhudzire thupi lathu mwadongosolo. Nazi zomwe tavumbulutsa pazowonjezera zotsutsana izi.
Kodi octinoxate ndi chiyani?
Octinoxate ali mgulu la mankhwala opangidwa posakaniza organic acid ndi mowa. Pankhaniyi, asidi sulfuric ndi methanol ophatikizana amapanga octinoxate.
Mankhwalawa adapangidwa koyamba m'ma 1950 kuti azisefa kuwala kwa UV-B kuchokera padzuwa. Izi zikutanthauza kuti zitha kuteteza khungu lanu kuti lisatenthedwe ndi khansa yapakhungu.
Zagwiritsidwa ntchito yanji?
Monga momwe mungayembekezere, popeza OMC imadziwika kuti imatchinga cheza cha UV-B, nthawi zambiri mumachipeza pamndandanda wazowonjezera zowotchera dzuwa. Opanga amagwiritsanso ntchito OMC mumitundu yonse yazodzikongoletsa komanso zodzisamalira kuti zisungidwe zatsopano komanso zothandiza. Ikhoza kuthandizanso khungu lanu kuyamwa bwino zosakaniza zina.
Komwe kuti muziyembekezera Icho
Kuphatikiza pa zoteteza ku dzuwa zotchuka kwambiri, mupeza octinoxate muzinthu zambiri zachilengedwe (zosakhala zachilengedwe) za khungu ndi zodzikongoletsera, kuphatikiza maziko a zodzoladzola, utoto wa tsitsi, shampu, mafuta odzola, opaka misomali, ndi mankhwala am'milomo.
Malinga ndi Database Products Houseat Database yochokera ku U.S. Department of Health and Human Services, makampani akuluakulu ngati Dove, L'Oréal, Olay, Aveeno, Avon, Clairol, Revlon, ndi ena ambiri, onse amagwiritsa ntchito octinoxate muzogulitsa zawo. Pafupifupi mankhwala onse oteteza ku dzuwa amagwiritsa ntchito ngati chinthu chachikulu.
Muyenera kuti mufufuze mndandanda wazowonjezera kuti muwone ngati chinthucho chimapangidwa ndi octinoxate. Amatchulidwa ndi mayina ambiri, kotero kuwonjezera pa octinoxate ndi octyl methoxycinnamate, muyenera kuyang'ana mayina monga ethylhexyl methoxycinnamate, escalol, kapena neo heliopan, mwa mayina ena angapo omwe angakhalepo.
Koma octinoxate ndi yotetezeka?
Apa ndi pamene zinthu zimakhala zovuta. Ngakhale idavomerezedwa kuti igwiritsidwe ntchito ku United States, U.S. Food and Drug Administration (FDA) imalepheretsa mphamvu ya fomuyi kuti ifike 7.5% octinoxate concentration.
Canada, Japan, ndi European Union amakhazikitsanso malire pazomwe zingagwiritsidwe ntchito ndi OMC. Koma kodi zoletsedwazi ndizokwanira kuti ogula akhale otetezeka kuvuto lililonse lomwe OMC lingayambitse?
Kafukufuku wochuluka akusonyeza kuti octinoxate imatha kukhala ndi zotsatira zoyipa pa nyama, komanso chilengedwe. Koma pakadali pano, kufufuza mozama za anthu kwakhala kochepa.
Kafukufuku wambiri wa anthu amayang'ana kwambiri zovuta zowoneka ngati zotupa ndi ziwengo pakhungu, ndipo sizikuwonetsa kuvulaza kwakukulu kwa anthu. Komabe, kupitiliza kafukufuku kumawonetsa kuti pakhoza kukhala zowona pazowonjezera zaumoyo ndi chitetezo chomwe anthu ambiri akukweza.
Ziphuphu
Ngakhale kuti nthawi zambiri imaphatikizidwa muzinthu zosamalira khungu kuti khungu lanu liwoneke bwino, anthu ena amati octinoxate imayambitsa ziphuphu.
Kafukufuku wina wapeza kuti octinoxate imatha kuyambitsa khungu, monga ziphuphu komanso kukhudzana ndi dermatitis mwa anthu. Koma izi zangowonetsedwa kuti zimachitika mwa anthu ochepa omwe ali ndi chifuwa cha khungu.
Zovuta zakubereka ndi chitukuko
Kafukufuku angapo apeza kuti octinoxate imatha kubweretsa zovuta zoberekera, monga kuchepa kwa umuna mwa amuna, kapena kusintha kwa kukula kwa chiberekero m'zinyama zanyama zomwe zimapezeka pamankhwala ocheperako kapena apamwamba. Komabe, maphunziro awa amachitika pa nyama, osati anthu. Nyamazo zinkadziwikanso ndi kuchuluka kwamankhwala kuposa momwe zimagwiritsidwira ntchito kunja kwa labu.
Kafukufuku wambiri wokhala ndi makoswe apeza umboni wamphamvu kuti OMC imatha kusokoneza machitidwe amkati. Octinoxate, motsimikizika, wapezeka kuti ndi "wosokoneza endocrine," mwa nyama, zomwe zikutanthauza kuti zimatha kusintha momwe mahomoni amagwirira ntchito.
Zovuta za Endocrine sizimamveka bwino, koma zimaganiziridwa kuti zimabweretsa chiopsezo chachikulu pakupanga makina, monga mwana wosabadwa kapena mwana wakhanda. Zovuta za Endocrine zalumikizidwa kwambiri ndi zovuta mu chithokomiro.
Zovuta zina zamachitidwe
Chodetsa nkhaŵa chachikulu ndi chakuti OMC imalowetsedwa mwachangu kudzera pakhungu ndikulowa m'magazi. OMC yapezeka mkodzo wamunthu. Zimapezekanso mkaka wa m'mawere wa anthu. Izi zapangitsa kuti omwe adalemba kafukufuku wina mu 2006 afotokozere kuti kuwonjezeka kwa mankhwala monga OMC kudzera mu zodzoladzola kumatha kukulitsa kuchuluka kwa khansa ya m'mawere mwa anthu, ngakhale pakadali pano, palibe maphunziro aumunthu otsimikizira izi.
Kafukufuku wochulukirapo amafunika kuti adziwe zomwe zingachitike kwa anthu nthawi yayitali. Pakadali pano, kuchuluka kocheperako kumakhalabe kofala ngati kololedwa muzinthu zambiri zaukhondo ndi zodzoladzola. Madera ena, komabe, akhazikitsa ziletso zawo ku OMC chifukwa chakuwonetsa umboni wazachilengedwe.
Zovulaza chilengedwe
Mwachitsanzo, mu Meyi wa 2018, opanga malamulo ku Hawaii adapereka chikalata choletsa kugwiritsa ntchito zoteteza ku dzuwa zomwe zili ndi octinoxate. Lamulo latsopanoli lidabwera pambuyo poti kafukufuku wa 2015 akuwonetsa kuti octinoxate imathandizira "kuyeretsa kwamiyala." Malinga ndi kafukufukuyu, mankhwala omwe amatetezedwa ndi dzuwa ndi ena mwazomwe miyala yamchere zam'madzi padziko lonse lapansi zikufa.
Mfundo yofunika
Kuchuluka kwa octinoxate mu zokongola ndi zinthu zosamalira anthu ndizomwe zimayambitsa mikangano padziko lonse lapansi. A FDA atsimikiza kuti padakali pano palibe umboni wokwanira kuti ndiwovulaza anthu kuti athetse ntchito wamba. Ngakhale kafukufuku adawonetsa kuti zovulaza makoswe ndi chilengedwe.
Asayansi ndi ogula ambiri amawaona ngati mankhwala owopsa omwe amafunikira kafukufuku wambiri, makamaka anthu. Kuyambira pano, kusankha kugwiritsa ntchito mankhwala omwe ali ndi octinoxate kwatsalira kwa inu.
Njira zina zopangira octinoxate
Ngati mukufuna kupewa zoopsa za octinoxate ndikugwiritsa ntchito zinthu zosamalira anthu zomwe mulibe mankhwalawa, konzekerani zovuta. Malo ogulitsa zakudya, masitolo apadera, ndi kugula pa intaneti kungapangitse kusaka kwanu kukhala kosavuta. Komabe, musangoganizira kuti zinthu zolembedwa ndi mawu ngati "zachilengedwe" zidzakhala zopanda OMC. Fufuzani muzosakaniza mndandanda wa mayina osiyanasiyana a mankhwalawa.
Zowotchera dzuwa ndizomwe mungafune m'malo mwanu. Octinoxate ndi amodzi mwamphamvu kwambiri opangidwa ndi dzuwa omwe amapezeka ndipo mitundu yambiri imagwiritsabe ntchito. Komabe, zoteteza ku dzuwa zachilengedwe zakutchire zikukwera.
Komwe zowotcha zowononga dzuwa zimagwiritsa ntchito mankhwala ngati octinoxate kuyamwa ndi kusefa ma radiation owopsa a dzuwa, zoteteza ku dzuwa zamchere zimagwira ntchito potembenuza dzuwa. Fufuzani zosankha zomwe zimalemba titaniyamu dioxide kapena zinc oxide monga chogwiritsira ntchito.
Makampani monga Goddess Garden, Badger, ndi Mandan Naturals amapanga zomwe nthawi zambiri zimatchedwa "reef-safe" zotchinga dzuwa zomwe zimagwira ntchito osagwiritsa ntchito OMC. Kutengera komwe mumakhala, mutha kupeza kapena osapeza zinthu zapaderazi m'mashelufu am'malo ogulitsira mankhwala.
Malo ogulitsira pa intaneti ngati Amazon ali ndi zoteteza ku dzuwa zambiri zopanda octinoxate zoti musankhe. Dermatologist wanu amathanso kukulimbikitsani kapena kukupatsani mankhwala opanda octinoxate omwe angakuthandizeni.
