I-Sunsafe DHHB (Diethylamino hydroxybenzoyl hexyl benzoate)sisihluzo se-UV esinokufunxa okuphezulu kuluhlu lwe-UV-A. Ukunciphisa ukuvezwa ngokugqithisileyo kwesikhumba somntu kwimitha ye-ultraviolet enokukhokelela kwifoto eyingozi kunye nengapheliyo,I-Sunsafe DHHBsisihluzo se-UV esine-oyile enyibilikayo enokuthi ifakwe kwisigaba seoli se-emulsions.

I-EDmaRC ifumene oku kulandelayo "Uphononongo lwe-Biomonitoring lubonisa ukuba ngaphezu kwe-90% yabantu baseDenmark bakhupha izihlungi ze-UV kumchamo wabo kungekhona nje ngexesha lasehlotyeni kodwa unyaka wonke. Ibangelwa kusetyenziso olubanzi lwemizi-mveliso yezihluzi ze-UV, kungekuphela kwizikhuseli zelanga kodwa nakwezinye ezininzi iimveliso zabathengi bemihla ngemihla, njengemveliso yokhathalelo lomntu, ukupakishwa kokutya, ifenitshala, iimpahla, isicoci, iithoyi, iiarhente zokucoca kunye nabanye abaninzi. Ukusetyenziswa okuxhaphakileyo kwezihluzi ze-UV kubangelwa ziimpawu zazo ezizodwa zokukhusela imibala ukuba ingabi mdaka kunye nokukhusela iplastiki ekunyibilikeni ngenxa yokutshiswa lilanga.

I-Sunsafe DHHByamkelwa eYurophu ngo-2005, kwaye ithengiswa nase-US, eMzantsi Melika, eMexico, eJapan naseTaiwan.

Isetyenziswa ekugxininiseni ukuya kuthi ga kwi-10% kwiimveliso ze-sunscreen, nokuba yodwa okanye idityaniswe nezinye i-UV absorbers.Ifototable kakhulu kwaye ibonelela ngokhuseleko oluluqilima lwe-UVA.

Ikwanayo nokunyibilika okulungileyo, ukuguquguquka kwefomula okugqwesileyo, kunye nokuhambelana kakuhle nezinye izihluzi ze-UV kunye nezithako zokuthambisa. I-Sunsafe DHHB ibonelela ngokugqwesileyo kokhuseleko lwe-radicals yasimahla kwaye ilungele ukhathalelo lwelanga oluhlala ixesha elide kunye neemveliso zokhathalelo lobuso bokuguga.
