Abstract
A process for preparing homogeneous and stable heavy-duty liquid detergent compositions which comprises forming a blend of a solution of a builder salt and an emulsifying agent at an elevated temperature above about 60.degree. C. and cooling said blend to a lower temperature below about 45.degree. C., the amount of said builder salt dissolved in said solution at the elevated temperature being greater than the solubility of said salt in water at the lower temperature, the nature and amount of the emulsifying agent being such as to maintain the builder salt in stable dispersion in said blend at the lower temperature. The finished composition contains a water-soluble detergent surface active agent.
Claims7
In a process for preparing a stable, aqueous, heavy duty liquid detergent containing by weight from about 5% to about 50% water soluble anionic detergent and from about 5% to about 50% builder salt in water, the improvement wherein the builder salt in water is heated at an elevated temperature above about 60.degree. in the presence of a stabilizing amount of fatty acid amide emulsifying agent and thereafter cooling the mixture to below about 40.degree. C, the amount of builder salt dissolved in said water at said elevated temperature being greater than the solubility of said builder salt in water at said lower temperature.
