Khoom Taw Qhia Thiab Daim Ntawv Thov
Octocrylene yog cov khoom siv organic nrog cov tshuaj formula C24H27TSIS MUAJ2, roj-soluble UV absorber, thiab yog insoluble hauv dej. Cov khoom uas ua rau muaj kev sib cais ntawm lwm cov roj-soluble solids. Nws muaj qhov zoo ntawm kev nqus siab, tsis muaj tshuaj lom, tsis muaj cov nyhuv teratogenic, kev ruaj ntseg zoo rau lub teeb thiab kub, thiab tuaj yeem nqus tau UV-B thiab ib qho me me ntawm UV-A.
