Avobenzone yog hluavtaws ultraviolet absorber, uas yog UV-A zoo (> 320nm) ultraviolet absorber. Nws tuaj yeem thaiv UVA ntawm tag nrho cov wavelength (320-400nm). Nws yog ib qho txiaj ntsig dav-spectrum roj-soluble UVA lim. Nws tuaj yeem muab tag nrho UVA thiab UVB tiv thaiv thaum ua ke nrog lwm cov tshuaj tiv thaiv UVB los tiv thaiv kab mob ntawm daim tawv nqaij los ntawm lub teeb.
25kg thawv los yog yuav tsum tau ntawm cov neeg siv khoom. Khaws nws kom deb ntawm lub teeb ntawm qhov kub hauv qab 25 ℃.
