Isihluzi se-UVA esifunxa kakhulu – iDiethylamino Hydroxybenzoyl Hexyl Benzoate

I-DHHB engakhuselekanga elangeni (I-Diethylamino hydroxybenzoyl hexyl benzoate)sisihluzo se-UV esinokufunxa okuphezulu kuluhlu lwe-UV-A. Sinciphisa ukuchayeka kakhulu kwesikhumba somntu kwimitha ye-ultraviolet enokukhokelela kumonakalo we-photodamage okhawulezileyo nongapheliyo,I-DHHB engakhuselekanga elangenisisihluzo se-UV esinyibilikayo kwioyile esinokufakwa kwisigaba seoyile seemulsions.

I-EDmaRC ifumanise oku kulandelayo “Uphando lwe-Biomonitoring lubonisa ukuba ngaphezulu kwe-90% yabemi baseDenmark bakhupha izihluzi ze-UV kumchamo wabo kungekuphela nje ngexesha lasehlotyeni kodwa unyaka wonke. Oku kubangelwa kukusetyenziswa ngokubanzi kwezihluzi ze-UV kwimizi-mveliso, kungekuphela nje kwizikhuseli zelanga kodwa nakwezinye iimveliso ezininzi zabathengi bemihla ngemihla, ezifana neemveliso zokhathalelo lomntu, ukupakishwa kokutya, ifenitshala, impahla, isepha, izinto zokudlala, izinto zokucoca kunye nezinye ezininzi. Ukusetyenziswa ngokubanzi kwezihluzi ze-UV kubangelwa ziimpawu zazo ezikhethekileyo zokukhusela imibala ekukhanyeni nasekukhuseleni iplastiki ekunyibilikeni ngenxa yokukhanya kwelanga.”

I-DHHB engakhuselekanga elangeniYavunywa eYurophu ngo-2005, kwaye ikwathengiswa eMelika, eMzantsi Melika, eMexico, eJapan naseTaiwan. Inesakhiwo seekhemikhali esifana neklasi yeziyobisi ze-benxophoenone zakudala, kwaye ibonisa ukuzinza okuhle kwefoto. Isetyenziswa kumanqanaba afikelela kwi-10% kwiimveliso ze-sunscreen, nokuba yodwa okanye xa idibene nezinye izinto ezifunxa i-UV.Iyakwazi ukufotwa lula kwaye ikhusela i-UVA ngamandla.

Ikwanayo nenyibilikayo elungileyo, iguquguqukayo yefomula egqwesileyo, kwaye ihambelana kakuhle nezinye izihluzi ze-UV kunye nezithako zokuhombisa. I-Sunsafe DHHB ibonelela ngokhuseleko oluhle kakhulu lwe-free radicals kwaye ifanelekile kwiimveliso zokhathalelo lobuso ezihlala ixesha elide kunye nokhathalelo lobuso oluchasene nokwaluphala.
