I-Octinoxate kwiiCosmetics: Into ekufuneka uyazi - Zempilo

Umxholo

Ushwankathelo

I-Octinoxate, ekwabizwa ngokuba yi-Octyl methoxycinnamate okanye i-OMC, yimichiza esetyenziswa rhoqo kwiimveliso zokuthambisa kunye nezolusu kwihlabathi liphela. Kodwa ngaba oko kuthetha ukuba kukhuselekile kuwe nakwintsapho yakho? Iimpendulo zixubekile.

Ukuza kuthi ga ngoku, akukho bungqina buninzi bokuba le khemikhali ibangela ingozi enkulu ebantwini. Nangona kunjalo, kubonisiwe ukuba kunokuba yingozi kwizilwanyana nakwindalo esingqongileyo.

Ngelixa izifundo ezinzulu ngakumbi zisaqhubeka, izifundo zexesha elide kusafuneka zigqitywe ngendlela i-octinoxate enokuthi iwuchaphazele ngayo umzimba womntu ngokwenkqubo. Nantsi into esiyityhilileyo malunga nale mpikiswano iphikisanayo.

Yintoni i-octinoxate?

I-Octinoxate ikudidi lweekhemikhali ezenziwe ngokudibanisa i-asidi ye-organic kunye notywala. Kule meko, i-acid ye-sulfuric kunye ne-methanol zidityanisiwe zenza i-octinoxate.

Le khemikhali yaqala ukuveliswa kwii-1950s ukucoca imitha ye-UV-B elangeni. Oko kuthetha ukuba kunokunceda ukukhusela ulusu lwakho ekutshisweni lilanga kunye nomhlaza wolusu.

Isetyenziselwa ntoni?

Kanye njengoko ubuya kulindela, kuba i-OMC yaziwa ngokuthintela imitha ye-UV-B, uyakuhlala uyifumana kuluhlu lwezithako ze-sun-counter-counter. Abavelisi baphinde basebenzise i-OMC kuzo zonke iintlobo zeemveliso zokuthambisa kunye nezobuqu ukunceda ukugcina izithako zabo zintsha kwaye zisebenza. Inokunceda ulusu lwakho ukuba lubone ngcono ezinye izithako.


Apho ungayikhangela

Ukongeza kwezona ziqhelekileyo zi-sunscreens, uya kufumana i-octinoxate kwizinto ezininzi eziqhelekileyo (ezingezizo ezomzimba) ulusu kunye neemveliso zezithambiso, kubandakanya isiseko sokwenza, idayi yeenwele, ishampu, into yokuthambisa, ipolishi yezikhonkwane kunye ne-lip balm.

NgokweDathabheyisi yeeMveliso zaseKhaya ezivela kwiSebe lezeMpilo laseMelika kunye neenkonzo zoLuntu, iinkampani eziqhelekileyo ezinje ngehobe, uL'Oréal, Olay, Aveeno, Avon, Clairol, Revlon, nabanye abaninzi, bonke basebenzisa i-octinoxate kwiimveliso zabo. Phantse yonke ikhemisi yelanga eqhelekileyo iyayisebenzisa njengeyona nto iphambili kuyo.

Kuya kufuneka umbe nzulu kuluhlu lwezithako ukubona ukuba imveliso yenziwe nge-octinoxate. Ibizwa ngamagama amaninzi, ke ukongeza kwi-octinoxate kunye ne-octyl methoxycinnamate, kuyakufuneka ujonge amagama afana ne-ethylhexyl methoxycinnamate, escalol, okanye neo heliopan, phakathi kwamanye amagama anokubakho.

Kodwa ngaba i-octinoxate ikhuselekile?

Nanku apho izinto zikhohlisayo. Nangona ngoku ivunyelwe ukusetyenziswa eUnited States, iU.S.Ukutya kunye noLawulo lweeDrug (FDA) kuthintela amandla kwifomula ukuya kuthi ga kwi-7.5% ye-octinoxate concentration.


I-Canada, i-Japan, kunye ne-European Union zikwabeka imida yokuba ingakanani imveliso enokuqulatha i-OMC. Kodwa ngaba ezi zithintelo zanele ukugcina abathengi bekhuselekile kuyo nayiphi na ingozi enokubangelwa yi-OMC?

Izifundo ezininzi zibonisa ukuba i-octinoxate inokuba neziphumo ezinobungozi kwizilwanyana, kunye nokusingqongileyo. Kodwa ukuza kuthi ga ngoku, uphando olunzulu ngabantu luthintelwe.

Uninzi lwezifundo zabantu zijolise kwiinkxalabo ezibonakalayo ezinje ngeerhashalala kunye nokwaliwa sisikhumba, kwaye khange zibonakalise ukwenzakala okukhulu ebantwini. Nangona kunjalo, ukuqhubeka kophando kubonisa ukuba kungakho ubunyani kwinkqubela phambili yezempilo kunye nokhuseleko abantu abaninzi abayinyusayo.

Amabala

Nangona ihlala ibandakanywa kwimveliso yokhathalelo lolusu ukwenza ibala lakho libukeke lingcono, abanye abantu bathi i-octinoxate ibangela induna.

Olunye uphando lufumanise ukuba i-octinoxate inokubangela ulusu olungalunganga, njenge-acne kunye ne-dermatitis ebantwini. Kodwa oku kuboniswe kuphela ukuba kwenzeka kubantu abambalwa abanolusu oluthile kulusu.

Iinkalo zokuzala kunye nokukhula

Izifundo ezininzi ziye zagqiba kwelokuba i-octinoxate inokubangela iingxaki zokuzala, ezinje ngesidoda esiphantsi emadodeni, okanye utshintsho kubungakanani besibeleko kwizilwanyana zaselebhu ezaziveliswe kwimilinganiselo emiselweyo okanye ephezulu yekhemikhali. Nangona kunjalo, ezi zifundo zenziwa kwizilwanyana, hayi ebantwini. Izilwanyana zikwabonakaliswe kumanqanaba aphezulu ekhemikhali kunokuba zisetyenziswa ngaphandle kwelebhu.


Izifundo ezininzi ngeempuku zifumene ubungqina obomeleleyo bokuthi i-OMC inokuchaphazela kakubi iinkqubo zangaphakathi. I-Octinoxate, ngokuqinisekileyo, ifunyenwe "ingumphazamisi we-endocrine," kwizilwanyana, oko kuthetha ukuba inokutshintsha indlela esebenza ngayo iihomoni.

Abaphazamisi be-Endocrine abaqondwa ngokupheleleyo, kodwa bacingelwa ukuba ngabona bantu babangela umngcipheko omkhulu ekuphuhliseni iinkqubo, njengosana olungekazalwa okanye usana olusandula ukuzalwa. Iziphazamiso ze-Endocrine zinxulunyaniswe ngokusondeleyo neziphumo ezibi ekusebenzeni kwe-thyroid.

Ezinye izinto ezixhalabisayo zenkqubo

Enye into exhalabisayo kukuba i-OMC ifunxwa ngokukhawuleza ngesikhumba nakwigazi. I-OMC ifunyenwe kumchamo womntu. Kuye kwafunyanwa kubisi lwebele lomntu. Oku kubangele ukuba ababhali besifundo esinye sango-2006 bacebise ukuba ukubonakaliswa okuphezulu kweekhemikhali ezinje nge-OMC ngokusebenzisa izinto zokuthambisa kunganegalelo kwizigulo zomhlaza wamabele ebantwini, nangona zisekho, okwangoku, akukho zifundo zabantu zokungqina oko.

Uphando olongezelelekileyo luyacelwa ukuba lubonakalise umngcipheko wexesha elide ebantwini. Okwangoku, amanqanaba asikelwe umda ahlala esiqhelo njengoko kuvumelekile kumawakawaka eemveliso zempilo nezithambiso. Eminye imimandla, nangona kunjalo, isungule izithintelo ze-OMC ngenxa yokuphuhlisa ubungqina bokuchaphazela okusingqongileyo.

Ukonakaliswa kwendalo

Ngomhla ka-Meyi ka-2018, umzekelo, abomthetho eHawaii bapasise umthetho oyilwayo othintela ukusetyenziswa kweescreen ezine-octinoxate. Lo mthetho mtsha ufike kwizithende zophando lowama-2015 ezibonisa ukuba i-octinoxate inegalelo "kwi-coral bleaching." Ngokophando, iikhemikhali ezikwi-sunscreen ziyinxalenye yezizathu zokufa kweekorale kwihlabathi liphela.

Umgca wezantsi

Inani elilinganiselweyo le-octinoxate kubuhle kunye neemveliso zokhathalelo lomntu yinto eqhelekileyo ekuphikisaneni nayo kwihlabathi liphela. I-FDA igqibe kwelokuba akukabikho bungqina baneleyo bokuba iyingozi ebantwini ukuyiphelisa kusetyenziso oluqhelekileyo. Nangona uphononongo lubonakalisile ukuba lenze ingozi kwiigundane kunye nokusingqongileyo.

Uninzi lwenzululwazi kunye nabathengi bayithatha njengechiza eliyingozi elidinga uphando ngakumbi, ngakumbi ebantwini. Ukuza kuthi ga ngoku, ukhetho lokuba uza kuyisebenzisa okanye ungayisebenzisi equkethe i-octinoxate ishiywe kuwe.

Ezinye iindlela zokwenza i-octinoxate

Ukuba ufuna ukunqanda umngcipheko onokubakho we-octinoxate kwaye usebenzise iimveliso zokhathalelo lomntu ezingenayo le khemikhali, zilungiselele umngeni. Iivenkile zokutya ezempilo, iivenkile ezikhethekileyo kunye nokuthenga kwi-intanethi kunokwenza ukuba ukukhangela kwakho kube lula Nangona kunjalo, sukucinga nje ukuba iimveliso ezinelebhile ezinamagama afana "nendalo" ziya kukhululeka ngokuzenzekelayo ngaphandle kwe-OMC. Khangela kuluhlu lwezithako kuwo onke la magama eekhemikhali.

Iisunscreen zezona mveliso zinokwenzeka ukuba kuya kufuneka ubeke endaweni yazo. I-Octinoxate yenye yezona ndawo zinamandla kakhulu kwiibhloko zekhemikhali ezikhoyo kwaye uninzi lweempawu zisayisebenzisa. Nangona kunjalo, i-sunscreens yendalo iyanyuka.

Apho ii-sunscreens eziqhelekileyo zisebenzisa imichiza efana ne-octinoxate ukufunxa nokucoca imitha yelanga eyingozi, i-sunscreens yamaminerali isebenza ngokuchasana nelanga. Khangela ukhetho olunoluhlu lwe-titanium dioxide okanye i-zinc oxide njengesithako esisebenzayo.

Iimpawu ezifana noothixokazi iGadi, iBadger, kunye neMandan Naturals zivelisa into ebizwa ngokuba yi "reef-safe" sunscreen esebenza ngaphandle kokusebenzisa i-OMC. Kuxhomekeka kwindawo ohlala kuyo, unokufumana okanye ungazifumani ezi zinto zikhethekileyo ezishelfini kwivenkile yakho yendawo.

Iivenkile ezikwi-Intanethi ezinje ngeAmazon zininzi ze-octinoxate-free sunscreens onokuthi ukhethe kuzo. Isikhumba sakho sinokukucebisa okanye sikunike imveliso yasimahla ye-octinoxate eya kukusebenzela.
