Dispersant wakili ne mai aiki na tsaka-tsaki tare da kaddarorin kishiyoyi biyu na lipophilicity da hydrophilicity a cikin kwayoyin halitta.

Watsawa tana nufin cakudar da aka samu ta hanyar tarwatsa wani abu (ko abubuwa da yawa) zuwa wani abu a cikin nau'in barbashi.

Dispersants iya uniformly tarwatsa m da ruwa barbashi na inorganic da Organic pigments da wuya a narke a cikin taya, da kuma hana sedimentation da condensation na barbashi, forming amphiphilic reagents da ake bukata ga barga suspensions.Houhuan sinadaran R & D da kuma samar da ruwa na tushen Additives da mai tushen Additives a daban-daban masana'antu, alaka surfactant Categories.

An rarraba tsarin watsawa zuwa: bayani, colloid da dakatarwa (emulsion).Don mafita, solute shine tarwatsawa kuma sauran ƙarfi shine tarwatsawa.Misali, a cikin maganin NaCl, mai rarraba shine NaCl, kuma mai rarraba ruwa ne.Mai watsawa yana nufin kayan da aka tarwatsa cikin barbashi a cikin tsarin watsawa.Wani abu kuma shi ake kira watsewar abu.
