1. A method for producing a multiphase washing or cleaning agent shaped body, comprising the steps of:
a) providing a first free-flowing washing or cleaning agent comprising at least 5-40 wt. % organic solvent and 20-90 wt. % surfactant;
b) providing a second free-flowing washing or cleaning agent, which is different from the first washing or cleaning agent, and comprises at least 30-95 wt. % organic solvent and a polymer film former;
c) feeding the first and second free-flowing washing or cleaning agents into an injector having one or more inner tubes and one or more outer tubes concentrically surrounding the one or more inner tubes;
d) introducing the first free-flowing washing or cleaning agent into a mold through the one or more inner tubes and introducing the second free-flowing washing or cleaning agent into the mold through the one or more outer tubes;
e) solidifying at least one of the first and second free-flowing washing or cleaning agents in the mold, thus forming a multiphase washing or cleaning agent shaped body; and
f) removing the multiphase washing or cleaning agent shaped body from the mold.
