I kēia manawa, hoʻohana nui ʻia ka 2,2 ', 4, 4'-tetrahydroxybenzophenone i nā plastics, resins, coatings, synthetic rubber a me nā ʻoihana ʻē aʻe, a hoʻohana ʻia ʻo 2,2', 4, 4'-tetrahydroxybenzophenone ma ke ʻano he mea lapaʻau waena, nā mea photosensitive, nā mea hoʻonaninani anti-ultraviolet additives a pēlā aku. I nā makahiki i hala iho nei, ua hoʻolohe nui ʻia ka hoʻohana ʻana i nā lole e ka ʻoihana textile, a ua ʻoi aku ka laulā o kona laulā.
25kg/pahu a e like me nā koi a ka mea kūʻai aku.
