Abstract: Colloidal silica aquasols containing about 200-675 ppm 1-(3-chloroallyl)-3,5,7-triaza-1-azoniaadamantane chloride; 100-350 ppm 1,2-benzisothiazolin-3-one; or 160-800 ppm of 1,3,5-triazine-1,3,5 (2H,4H,6H)-triethanol are protected from contamination by microorganisms which cause undesirable changes in physical properties. This treatment prevents discoloration, bad odor and slime formation and increases the shelf life of colloidal silica sols to more than one year.
