Isihlungi Se-UVA Sokumuncwa Okuphezulu – Diethylamino Hydroxybenzoyl Hexyl Benzoate

I-Sunsafe DHHB (I-Diethylamino hydroxybenzoyl hexyl benzoate)isihlungi se-UV esimunca kakhulu ebangeni le-UV-A.Ukunciphisa ukuchayeka ngokweqile kwesikhumba somuntu emisebeni ye-ultraviolet engaholela ekulimazeni okunamandla nokungapheli,I-Sunsafe DHHBiyisihlungi se-UV esincibilika ngamafutha esingase sifakwe esigabeni samafutha se-emulsion.

I-EDmaRC ithole lokhu okulandelayo “Ucwaningo lwe-Biomonitoring lubonisa ukuthi ngaphezu kwe-90% yabantu baseDenmark bakhipha izihlungi ze-UV emchameni wabo hhayi nje ngesikhathi sasehlobo kodwa unyaka wonke.Kubangelwa ukusetshenziswa okubanzi kwezimboni zezihlungi ze-UV, hhayi kuphela kuma-sunscreens kodwa nakweminye imikhiqizo eminingi yansuku zonke yabathengi, njengemikhiqizo yokunakekelwa komuntu siqu, ukupakisha ukudla, ifenisha, izingubo, okokuhlanza, amathoyizi, izinto zokuhlanza nokunye okuningi.Ukusetshenziswa kakhulu kwezihlungi ze-UV kubangelwa izici zazo eziyingqayizivele zokuvikela imibala ekufiphaleni nokuvikela ipulasitiki ekuncibilikeni ngenxa yokushiswa yilanga.”

I-Sunsafe DHHByavunywa eYurophu ngo-2005, futhi imakethwa nase-US, eNingizimu Melika, eMexico, eJapane naseTaiwan.Inesakhiwo samakhemikhali esifana nesigaba sezidakamizwa se-benxophoenone sakudala, futhi ibonisa ukuhleleka okuhle kwezithombe.Isetshenziswa ekugxiliseni okufika ku-10% emikhiqizweni yokuvikela ilanga, kungaba iyodwa noma ihlanganiswe nezinye izimunyisi ze-UV.Iyakwazi ukuthwebula izithombe futhi ihlinzeka ngokuvikeleka okuqinile kwe-UVA.

Futhi inokuncibilika okuhle, ukuguquguquka kwefomula okuhle kakhulu, nokuhambisana okuhle nezinye izihlungi ze-UV kanye nezithako zezimonyo.I-Sunsafe DHHB inikeza ukuvikelwa okuhle kakhulu kwama-radicals mahhala futhi ilungele ukunakekelwa kwelanga okuhlala isikhathi eside kanye nemikhiqizo yokunakekela ubuso elwa nokuguga.
