Kev siv:
Benzophenone-4 yog dej-soluble & yog pom zoo rau lub hnub muaj kev tiv thaiv lub hnub muaj ntau yam. Kev ntsuam xyuas tau qhia tias Benzophenone-4 ruaj khov lub viscosity ntawm cov gels raws li
Polyacrylic acid (carbopol, pemulen) thaum lawv raug rau UV hluav taws xob. Cov kev ua kom tsawg li 0.1% muab cov txiaj ntsig zoo. Nws yog siv ua ultra-violet stabilizer nyob rau hauv cov ntaub plaub, tshuaj pleev ib ce, tshuaj tua kab & lithographic phaj txheej. Nws yuav tsum tau sau tseg
Tha Tbenzopenone-4is tsis tau tshaj mg ntsev, tshwj xeeb hauv cov roj-roj emulsions. Benzophenone-4 muaj cov xim daj uas ua rau muaj ntau dua hauv cov alkaline ntau & tej zaum hloov cov kev daws teeb meem xim.
