Heavy-duty liquid detergent

摘要

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 DEG C. and cooling said blend to a lower temperature below about 45 DEG 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.
