Kugwiritsa ntchito

Pakadali pano, 2, 2 ', 4, 4'-tetrahydroxybenzophenone imagwiritsidwa ntchito kwambiri mu mapulasitiki, ma resini, zokutira, mphira wopangidwa ndi zinthu zina, 2, 2', 4, 4 '-tetrahydroxybenzophenone imagwiritsidwa ntchito ngati mankhwala ophatikizika, zinthu zowunikira kuwala, zowonjezera zodzoladzola zotsutsana ndi ultraviolet ndi zina zotero. M'zaka zaposachedwapa, kugwiritsa ntchito nsalu kwakhala kukuyang'aniridwa ndi makampani opanga nsalu, ndipo kukula kwake kuli kwakukulu.
