  • Publication number: 20120088710
    Abstract: A liquid alkaline cleaning agent preparation for automatic dispensing during automatic dishwashing or textile cleaning includes a) 15 to 60% by weight of a builder, b) <5% by weight of silicate and c) 30 to 80% by weight of water. These cleaning agents have a good thermal stability and are therefore suitable for automatic dispensing methods and are furthermore characterized by a substantially improved cleaning performance.

  • Publication number: 20120088709
    Abstract: Disclosed are liquid alkaline detergent preparations that are to be dispensed automatically when washing dishes in a dishwasher, comprising: a) 15 to 60 percent by weight of builder; b) 30 to 80 percent by weight of water; and c) less than 5 percent by weight of surfactant. Because of their thermal stability, the detergent preparations are particularly suitable for carrying out automatic dispensing processes when washing dishes in a dishwasher and washing fabrics in a washing machine. Furthermore, the detergent preparations are characterized by significantly improved cleaning power compared with conventional methods.
