ʻO Benzophenone-4 he wai hoʻoheheʻe ʻia a ʻōlelo ʻia no nā kumu pale kiʻekiʻe o ka lā.Ua hōʻike nā ho'āʻo e hoʻokūpaʻa ʻo Benzophenone-4 i ka viscosity o nā gels e pili ana

polyacrylic acid (Carbopol, Pemulen) i ka wā e ʻike ʻia ai lākou i ka radiation UV.ʻO ka haʻahaʻa e like me ka 0.1% hāʻawi i nā hopena maikaʻi.Hoʻohana ʻia ia e like me ka ultra-violet stabilizer i ka hulu hipa, nā mea hoʻonaninani, nā pesticides & lithographic plate coating.Pono e hoʻomaopopo

ʻAʻole kūpono ʻo tBenzophenone-4 me nā paʻakai Mg, ʻoi loa i nā emulsions wai-ʻaila.He kala melemele ka Benzophenone-4 e lilo ana i mea ikaika loa i ka pae alkaline & hiki ke hoʻololi i ke kumu o nā hāʻina kala.
