Mumakore gumi apfuura, kudiwa kwekuvandudzwa kwekudzivirirwa kweUVAyakanga ichikura nekukurumidza.
Mwaranzi yeUV ine migumisiro yakaipa, kusanganisira kupiswa nezuva, mufananidzo-kukwegura uye kenza yeganda. Mhedzisiro iyi inogona kudzivirirwa chete nekudzivirira kubva kumwaranzi yeUV, kusanganisira UVA.
Kune rumwe rutivi, kunewo tsika yekuderedza huwandu hwe "makemikari" paganda. Izvi zvinoreva kuti UV absolute inoshanda zvikurumaRberinofanira kuwanikwa nekuda kwechinodiwa chitsva chekudzivirira UV yakafara.Kuchengetedzwa Nezuva-BMTZ（Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine yakagadzirwa kuti iite zvinodiwa izvi. Inogara ichipfava, inonyungudika mumafuta, inoshanda zvikuru uye inofukidza huwandu hweUVB neUVA. Mugore ra2000, vakuru vakuru vekuEurope vakawedzera Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine pane runyorwa rwezvinhu zvinonyungudutsa UV zvinoyevedza.
•UVA:Mapoka maviri e-ortho-OH anodiwa kuti simba riparadzwe zvakanaka kuburikidza nemabhuroko ehydrogen ari mukati memamorekuru. Kuti simba rinyatsopinda muUVA, nzvimbo dziri pakati pema phenyl maviri dzinofanira kutsiviwa neO-alkyl, zvichikonzera bis-resorcinyl triazine chromophor.
•UVB:Boka re phenyl rasara rakabatana ne triazine rinotungamira mukunyudzwa kwe UVB. Zvinogona kuratidzwa kuti kushanda kwakanyanya kwe "full spectrum" kunowanikwa ne O-alkyl iri mu para-position. Pasina zvinotsiva zvinonyungudutsa, HPTs hadzinyungudike mumafuta ekuzora. Dzinoratidza hunhu hwakajairika hwe pigments (semuenzaniso, nzvimbo dzakanyanya kunyunguduka). Kuti kuwedzere kunyunguduka muzvikamu zvemafuta, chimiro che UV filter chakagadziriswa zvinoenderana.
