Siv:

Benzophenone-4 yog dej-soluble & raug pom zoo rau lub hnub tiv thaiv ntau 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.
