  • Structured aqueous detergent compositions containing salting-out electrolytes and surfactants and methods of forming them
    Patent number: 5021195
    Abstract: A structured aqueous detergent composition containing detergent-active material in the form of at least one detergent-active component and at least one electrolyte and having the following phases:(a) an isotropic aqueous solution forming a continuous phase;(b) distributed and suspended in said solution (a) discrete units of one or more non-network-forming phases, each selected from the following:(i) solid particles containing detergent-active material,(ii) lyotropic liquid crystals containing detergent-active material; and(iii) non-encapsulated liquid droplets containing detergent-active material,(c) one or more suspending phases which cause the composition to be structured so as to suspend the non-network-forming phase (b); said non-network-forming phase (b) having a higher concentration by weight of detergent-active material than said aqueous solution (a).
