摘要：
A method of stabilizing silica-containing anionic microparticles upon mixing of the silica-containing anionic microparticles with hard water comprising adding one or more hardness-abating additives to the hard water prior to mixing of the hard water and the silica-containing anionic microparticles or adding an effective stabilizing amount of one or more hardness-abating agents to the silica-containing anionic microparticles prior to mixing of the hard water with the silica-containing anionic microparticles and a stabilized composition comprising silica-containing anionic microparticles and an effective stabilizing amount of one or more hardness-abating additives.
