Abstract
Detersive systems that can be used to remove soil from fabrics, dishware, flatware, hard surfaces, clean-in-place installations, and other common household, institutional or industrial locations can contain a detergent capable of removing soil and a softening agent dispersed in the detergent comprising droplets having an exterior organic phase containing a complexing agent and an inner aqueous phase comprising an acid. The softening agent can adequately remove hardness ions from the detersive system made from the compositions of the invention.
