Abstract
A detergent system, especially adapted for single-use applications, in the form of a fluid-tight container having two separate layers of liquid compositions therein, one of the liquid compositions comprising a predetermined volume of a concentrate of a surfactant or detergent, and the other composition comprising a predetermined volume of a concentrate of an inorganic builder. The compositions are characterized in that, if mixed together in their concentrated form, they would be incompatible or immiscible, and would result in a non-homogeneous mixture. However, the compositions are so related as to the ingredients and proportions thereof, that when the separate layers are poured from the container into a predetermined volume of a diluent such as water, a stable cleaning or detergent solution or dispersion is obtained in ready-to-use form.
