Daim ntawv thov
Benzophenone-4 yog ib qho dej-soluble & pom zoo rau lub hnub tiv thaiv siab tshaj plaws. Kev ntsuam xyuas tau pom tias Benzophenone-4 stabilizes viscosity ntawm gels raws li polyacrylic acid (Carbopol, Pemulen) thaum lawv raug UV hluav taws xob. Concentrations tsawg li 0.1% muab cov txiaj ntsig zoo. Nws yog siv los ua ultra-violet stabilizer hauv wool, tshuaj pleev ib ce, tshuaj tua kab & lithographic phaj txheej. Nws yuav tsum tau sau tseg
tha tBenzophenone-4 tsis sib xws nrog Mg ntsev, tshwj xeeb tshaj yog nyob rau hauv dej-roj emulsions. Benzophenone-4 muaj xim daj uas dhau los ua ntau dua hauv cov alkaline ntau & tuaj yeem hloov pauv vim yog xim xim.
