I-AvobenzoneCAS70356-09-1 – Isithako Esibalulekile Emkhakheni Wokuvikela Ilanga kanye Nemikhuba Yaso Yemakethe

Eminyakeni yamuva nje, ngokuthuthukiswa okuqhubekayo kokuqwashisa kwabantu ngokuvikelwa kwelanga, imakethe yemikhiqizo yokuvikelwa kwelanga ibonise ukuthambekela okuthuthukayo. Phakathi kwezithako eziningi zokuvikelwa kwelanga, i-avobenzone, njenge-ejenti ebalulekile yokuvikela ilanga, ithole ukunakwa kabanzi.

I-Avobenzone iyisithako esincibilika emafutheni, futhi amagama ayo okuhweba afaka phakathi i-Parsol 1789, i-Eusolex 9020, i-Escalol 517, njll. Njenge-derivative ye-dibenzoylmethane, ingamunca i-UVA yazo zonke izilinganiso zamaza, ikakhulukazi inezinga eliphakeme kakhulu lokumunca i-UVA elinobude bamaza obungama-nanometer angu-357. Ngakho-ke, isetshenziswa kabanzi emikhiqizweni eminingi evikela elangeni elibanzi, okungavimbela ngempumelelo ukushiswa yilanga futhi kunciphise ingozi yomdlavuza wesikhumba.

Kodwa-ke, i-avobenzone ayiyona into engenakuphikiswana. Ucwaningo olwenziwe yi-US Food and Drug Administration (FDA) lwakhe lwaveza ukuthi izithako ezivamile zamakhemikhali okuvikela ilanga njenge-avobenzone zingangena egazini, futhi ukuhlushwa kwemithi egazini kudlula kakhulu umkhawulo wokuphepha obekwe yi-FDA, okubangela ukukhathazeka komphakathi mayelana nokuphepha kwemikhiqizo yokuvikela ilanga. Okwamanje, i-FDA iphinde yagcizelela ukuthi uma ubheka ukuthi ama-sunscreen afakazelwe ukuthi adlala indima ebalulekile ekuvimbeleni umdlavuza wesikhumba kanye neminye imiphumela eyingozi yemisebe ye-ultraviolet, abathengi akufanele bayeke ukusebenzisa ama-sunscreen ngenxa yalokhu, kodwa bangakhetha imikhiqizo ephephile, njengaleyo equkethe ama-sunscreen agents angokwenyama njenge-zinc oxide kanye ne-titanium dioxide.

Ngaphezu kwalokho, ngesikhathi sokusetshenziswa kwe-avobenzone, kufanele kuqashelwe nokuqina kwayo. Kufanele kugwenywe ukuthi ihlangane nama-ion ensimbi ukuze kuvinjelwe ukushintsha kombala, futhi kufanele isetshenziswe ngokwesilinganiso esinconywayo ukuqinisekisa ukuphepha nokusebenza kahle kwemikhiqizo. Kubathengi, lapho bekhetha imikhiqizo yokuvikela ilanga equkethe i-avobenzone, kunconywa ukuthi benze ukuhlolwa kwendawo encane esikhumbeni kuqala ukuze babone ukuthi kukhona yini ukusabela kokungezwani komzimba.

Sekukonke, isikhundla esibalulekile se-avobenzone emkhakheni wokuvikelwa kwelanga asinakushaywa indiva, kodwa ucwaningo lokuphepha olufanele kanye nokuqapha nakho kudingeka kuqiniswe njalo ukuqinisekisa ukuthi abathengi bangasebenzisa imikhiqizo yokuvikelwa kwelanga ngokuphephile nangokuphumelelayo ukuze bamelane nomonakalo wemisebe ye-ultraviolet esikhumbeni. Ngesikhathi senqubo yokukhiqiza, amabhizinisi kufanele futhi alawule ngokuqinile ikhwalithi, alandele amazinga kanye nemininingwane efanele, futhi akhuthaze intuthuko enempilo ye-avobenzone emakethe yokuvikelwa kwelanga.
