Abstract

Disclosed are aqueous liquid detergent compositions comprising dispersed particles of a silicone-based suds suppressor system and a separately added moderately hydrophobic particulate silica stabilizing agent. Such a separately added stabilizing agent serves to retard coalescence and coagulation of the suds suppressor particles and thus enhances the storage stability of the suds suppressor-containing detergent compositions of this invention.
