Method For Producing A Washing Agent Portion Unit With Improved Optical And Rheological Properties

A method for producing a washing agent portion unit having at least one filled receiving chamber surrounded by a water-soluble film, comprising the steps of:

• a) transporting a first water-soluble film in the direction of a dosing station at a speed of 0.04 m/s;
• b) molding the first water-soluble film into the cavities of a deep-drawing die located below the water-soluble film, so as to form at least one cavity having a maximum diameter in the direction of travel of the film of between 3 and 75 mm;
• c) filling the cavity by means of the dosing station with a first flowable washing agent preparation containing, based on its total weight,
• i) 20 to 80 wt. % surfactant;
• ii) 2 to 15 wt. % fatty acid;
• iii) 0.3 to 8 wt. % of the salt of a divalent cation;
• iv) 8 to 35 wt. % solvent;
• d) further transporting the filled cavity in the direction of a sealing station at a speed of 0.04 m/s;
• e) sealing the filled cavity with a second water-soluble film.
