Mumakore gumi apfuura kudiwa kwekuvandudzwa kweUVA dziviriroyakanga ichiwedzera nokukurumidza.
UV radiation ine mhedzisiro yakaipa, kusanganisira kupisa kwezuva, mufananidzo-kukwegura uye kenza yeganda. Izvi zvinokonzeresa zvinogona kudzivirirwa chete nekudzivirira kubva kune ese akasiyana e UV mwaranzi, kusanganisira UVA.
Kune rumwe rutivi kunewo maitiro ekuderedza kuwanda kwe "makemikari" paganda. Izvi zvinoreva kuti inoshanda chaizvo UV absorbersinofanira kuwanikwa kune chitsva chinodiwa cheyakafara UV dziviriro.Sunsafe-BMTZ(Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine yakagadzirwa kuti izadzise zvinodiwa izvi. Iyo ine mufananidzo-yakagadzika, mafuta-inonyungudika, inoshanda zvakanyanya uye inovhara iyo UVB uye UVA renji. Mugore ra2000, zviremera zveEurope zvakawedzera Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine kune yakanaka runyorwa rwezvekuzora UV zvinonyudza.
•UVA:Mapoka maviri e-ortho-OH anodiwa kuti simba rishande rinoparadza kuburikidza ne intramolecular hydrogen mabhiriji. Kuti uwane kunyura kwakasimba muUVA, mapara-positions ezvikamu zviviri zvephenyl anoenderana anofanira kutsiviwa neO-alkyl, zvichiita kuti bis-resorcinyl triazine chromophor.
•UVB:Boka rephenyl rakasara rakasungirirwa kune triazine rinotungamira kutorwa kweUVB. Zvinogona kuratidzwa kuti maximal "full spectrum" kuita kunowanikwa neO-alkyl iri mupara-chinzvimbo. Pasina solubilizing substituents, HPTs dzinenge dzisina kunyungudika mumafuta ekuzora. Ivo vanoratidza zvakajairwa zvimiro zvepigment (semuenzaniso, yakakwirira melting point). Kuti uwedzere kunyungudika muzvikamu zveoiri, chimiro cheiyo UV sefa yakagadziridzwa zvinoenderana.
