A method for the production of multi-phase detergents or cleaning agents, comprising the production of a water-soluble or water-dispersible container; the filling of said container with detergents or cleaning agents; application of a separating layer and filling of said container with other detergents or cleaning agents. The method is characterized in that a liquid separating agent is applied in order to form the separating layer, said agent solidifying in order to form the separating layer; the amount of packaging material used is reduced and the number of method steps is also reduced. the invention is further characterized by optimized use of space in the packaging body.
