    The protective power of the lyophilic colloids is expressed in terms of gold number a term introduced by Zsigmondy Gold number is the number of milligram of the protective colloid which prevent the coagulation of 10 ml of red gold sol, when 1 ml of a 10 percent solution of sodium chloride is added to it. Thus, smaller the gold number of lyophilic colloid, the greater is the protective power.
