Zosefera Zapamwamba za UVA - Diethylamino Hydroxybenzoyl Hexyl Benzoate

Sunsafe DHHB (Diethylamino hydroxybenzoyl hexyl benzoate)ndi fyuluta ya UV yomwe imayamwa kwambiri mumtundu wa UV-A. Kuchepetsa kuchulukirachulukira kwa khungu la munthu ku radiation ya ultraviolet yomwe ingayambitse kuwonongeka kwakukulu komanso kosatha,Sunsafe DHHBndi zosefera zosungunuka za UV zomwe zimatha kuphatikizidwa mugawo lamafuta la emulsions.

EDmaRC yapeza zotsatirazi "Kafukufuku wa Biomonitoring akuwonetsa kuti oposa 90% a anthu aku Danish amachotsa zosefera za UV mumkodzo wawo osati nthawi yachilimwe komanso chaka chonse. Zimayamba chifukwa chogwiritsa ntchito kwambiri zosefera za UV m'mafakitale, osati pa zotchingira dzuwa zokha komanso pazinthu zina zambiri zatsiku ndi tsiku, monga zinthu zosamalira anthu, zonyamula chakudya, mipando, zovala, zotsukira, zoseweretsa, zoyeretsa ndi zina zambiri. Kugwiritsa ntchito kwambiri zosefera za UV kumatheka chifukwa cha mawonekedwe ake apadera oteteza mitundu kuti isachite manyazi komanso kuteteza pulasitiki kuti isasungunuke chifukwa cha dzuwa. ”

Sunsafe DHHBidavomerezedwa ku Europe mu 2005, ndipo imagulitsidwanso ku US, South America, Mexico, Japan ndi Taiwan. Ili ndi kapangidwe kamankhwala kofanana ndi kalasi yamankhwala ya benxophoenone yachikale, ndipo imawonetsa kukhazikika bwino. Amagwiritsidwa ntchito mokhazikika mpaka 10% pazinthu zoteteza dzuwa, kaya yekha kapena kuphatikiza ndi zowukira zina za UV.Ndiwojambula kwambiri ndipo imapereka chitetezo champhamvu cha UVA.

Ilinso ndi kusungunuka kwabwino, kusinthasintha kwabwino kwa fomula, komanso yogwirizana ndi zosefera zina za UV ndi zopangira zodzikongoletsera. Sunsafe DHHB imapereka chitetezo chabwino kwambiri cha ma radicals aulere ndipo ndiyabwino pakusamalira dzuwa kwanthawi yayitali komanso mankhwala oletsa kukalamba amaso.
