I-AvobenzoneCAS706-09-1 - Isithako Esibalulekile Ensimini Yokuvikelwa Kwelanga Nezitayela Zalo Zemakethe

Eminyakeni yamuva nje, ngokuthuthuka okuqhubekayo kokuqwashisa kwabantu ngokuvikelwa kwelanga, imakethe yemikhiqizo yokuvikela ilanga ikhombise inkambiso yentuthuko ekhulayo. Phakathi kwezithako zokuvikelwa kwelanga eziningi, i-avobenzone, njenge-ejenti ye-sunscreen yelanga ebaluleke kakhulu, ithole ukunakwa okubanzi.

I-Avobenzone isithako esinyibilikisiwe, futhi amagama ayo okuhweba afaka i-parsol 1789, eusolex 9020, escalol 517, njll. Ngakho-ke, kusetshenziswa kabanzi emikhiqizweni eminingi efuna ukuvikelwa kwelanga okubanzi, okungavimbela ngempumelelo ukushiswa yilanga nokunciphisa ubungozi bomdlavuza wesikhumba.

Kodwa-ke, i-avobenzone ayikho impikiswano. Ucwaningo olwenziwa yi-US Food and Drug Administration (FDA) uma lukhombe ukuthi izithako zamakhemikhali ezijwayelekile ze-sunscreen ezinjenge-avobenzone zingangena egangeni, futhi ukuqunjelwa kwezidakamizwa zegazi kungadlula kude umkhawulo we-FDA, kubangele ukukhathazeka komphakathi mayelana nokuphepha kwemikhiqizo yokuvikela ilanga. Ngaleso sikhathi, i-FDA nayo igcizelele ukuthi ukubheka ukuthi ama-sunscreens afakazelwe ukuthi adlale indima ebalulekile ekuvimbeleni umdlavuza wesikhumba neminye imiphumela ephephile, njengaleyo equkethe ama-ejenti we-zinc onide kanye ne-titanium dioxide.

Ngaphezu kwalokho, ngesikhathi sokusetshenziswa kwe-avobenzone, ukunakwa kufanele nakho kukhokhelwe ukuqina kwalo. Kufanele kugwenywe ukuthintana ne-Metal Ion ukuvikela ukuguquguquka, futhi kufanele kusetshenziswe ngokuya ngomthamo onconyiwe ukuze kuqinisekiswe ukuphepha nokusebenza kahle kwemikhiqizo. Kubathengi, lapho ukhetha imikhiqizo yokuvikela ilanga equkethe i-avobenzone, kunconywa ukwenza ukuhlolwa kwendawo encane esikhunjeni kuqala ukuze kubonakale ukuthi kukhona ukusabela komzimba.

Sekukonke, isikhundla esibalulekile se-avobenzone emkhakheni wokuvikelwa kwelanga asinakwa, kepha ucwaningo olufanele lokuphepha nokugadwa kudinga ukuqiniswa ngokuqhubekayo ukuqinisekisa ukuthi abathengi bangasebenzisa imikhiqizo yokuvikela ilanga ngokuphepha nangokufanele ukumelana nemisebe ye-ultraviolet esikhunjeni. Ngesikhathi senqubo yokukhiqiza, amabhizinisi kufanele futhi alawule kahle ikhwalithi, alandele amazinga afanele kanye nokucaciswa, futhi akhuthaze ukuthuthukiswa okunempilo kwe-avobenzone emakethe yokuvikela ilanga.
