Wax-ku-darka dufanka ee dareeraha shaqada birta
Taxanaha Ester ee dareeraha shaqada birta
Monoesters, diesters iyo polyol esters ee acids dufanka leh ee loo isticmaalo dareeraha birta salida ee saliidda si loo yareeyo xiisadda dusha sare ee u dhaxaysa saliidda iyo birta, waxay bixiyaan xoog fiiqan oo wanaagsan.
Dheecaan biyo-ku-salaysan birta, waxay u isticmaashay milaan saliid waxayna keentaa EP iyo ka-saareyaasha daxalka.
