Dispersant o le pauta eseese talafeagai taape i le solvent, e ala i se mataupu faavae repulsion tau po o le polymer steric aafiaga faalavelave, ina ia o ituaiga uma o le mautu e matua mautu taofi i le solvent (po o le faasalalauina). fa'afeagai meatotino ole oleophilic ma hydrophilic i molecule.It e mafai ona laugatasia tutusa vaega malo ma vai o pigments inorganic ma organic e faigata ona solo i le vai.
O le dispersant sili ona lelei ma le siosiomaga faauo e le mafai ona mu ma e le corrosive, ma e mafai ona soluble e le iʻu i le vai, e le mafai ona solu i ethanol, acetone, benzene ma isi solvents organic. E sili ona lelei le faasalalauina o aafiaga i le kaolin, titanium dioxide, calcium carbonate, barium sulfate, talcum paʻu, zinc oxide, uʻamea oxide samasama ma isi pigments, ma e talafeagai foi mo le taape fefiloi pigments.
