Iyini ukusetshenziswa kwe-Avobenzone?

I-Avobenzone,eyaziwa nangokuthi i-Parsol 1789 noma i-butyl methoxydibenzoylmethane, isakhi samakhemikhali esivame ukusetshenziswa njengesithako kumakhilimu okuvikela ilanga neminye imikhiqizo yokunakekela umuntu. Kuyi-ejenti esebenza kahle kakhulu yokumunca i-UV esiza ukuvikela isikhumba emisebeni ye-UVA eyingozi, yingakho ngokuvamile itholakala ezikhiqizweni zelanga ezibanzi.

Inombolo ye-CAS ye-Avobenzone ithi 70356-09-1. Impushana ephuzi, engancibiliki emanzini kodwa encibilika kuzincibilikisi eziningi eziphilayo, okuhlanganisa amafutha notshwala. I-Avobenzone iyisithako esikwazi ukuthwebula izithombe, okusho ukuthi ayibhidliki lapho ichayeke elangeni, okuyenza ibe ukukhetha okudumile kumakhilimu okuvikela ilanga.

I-Avobenzoneimunca imisebe ye-UVA ngokuyiguqula ibe amandla angayingozi kangako ngaphambi kokuba ingene esikhunjeni. I-compound inezinga eliphezulu lokumunca ku-357 nm futhi iphumelela kakhulu ekuvikeleni emisebeni ye-UVA. Imisebe ye-UVA yaziwa ngokudala ukuguga ngaphambi kwesikhathi, imibimbi, nokunye ukulimala kwesikhumba, ngakho i-avobenzone ingumdlali obalulekile ekuvikeleni isikhumba emiphumeleni yokuchayeka elangeni.

Ngaphezu kwama-sunscreens,i-avobenzoneisetshenziswa nakweminye imikhiqizo yokunakekelwa komuntu siqu, njengama-moisturizers, ama-lip balms, nemikhiqizo yokunakekelwa kwezinwele. Ukuvikela kwayo okubanzi emisebeni ye-UVA kuyenza ibe isithako esiwusizo emikhiqizweni eminingi eyahlukene efuna ukuvikela isikhumba nezinwele ekulimaleni.

Naphezu kokukhathazeka okuthile mayelana nokuphepha kwe-avobenzone, ucwaningo luye lwabonisa ukuthi iphephile futhi iyasebenza uma isetshenziswa njengoba kuqondiswe kuma-sunscreens neminye imikhiqizo yokunakekelwa komuntu siqu. Ifakwe ohlwini lwe-FDA lwezithako ezisebenzayo ezigunyaziwe ezingasetshenziswa kuma-sunscreens, futhi isetshenziswa kabanzi ezinhlotsheni eziningi zemikhiqizo.

Sekukonke,i-avobenzoneiyisithako esibalulekile emikhiqizweni eminingi yokunakekelwa komuntu siqu, ikakhulukazi izinto zokuvikela ilanga, ngenxa yekhono layo lokuvikela emisebeni ye-UVA eyingozi. Ukuqina kwezithombe nekhono layo lokusetshenziswa kumafomula ahlukene ahlukahlukene kuyenza ibe isithako esisebenza ngezindlela eziningi esizohlala lapha. Ngakho-ke, uma ngokulandelayo ufuna okokuvikela ilanga, hlola i-avobenzone ohlwini lwezithako ezisebenzayo ukuze uqinisekise ukuthi uthola ukuvikeleka okungcono kakhulu ngangokunokwenzeka.
