Abstract

Aqueous, liquid, multiphase, surfactant-containing cleaning composition having at least two continuous phases, having at least one lower aqueous phase I and an upper aqueous phase II immiscible with the lower phase I and which can be temporarily converted into an emulsion by shaking, wherein the composition contains one or more hydrophobic components and up to about 5% by weight of sodium hexametaphosphate. The compositions are useful as hard surface cleaners.
