  • Publication number: 20040053808
    Abstract: The invention relates to washing or cleaning agent shaped bodies that are mechanically stable, have an excellent rate of dissolution and a completely novel appearance. The novel washing or cleaning agent shaped bodies comprise solid(s) and gas(es) and optionally other washing or cleaning agent components. The shaped body consists of gas-filled cells (pores) that are defined by solid dividing walls. Preferred washing or cleaning agent shaped bodies in the form of solid foams have a content of 40 to 90% by weight of one or more water-soluble polymers, 10 to 60% by weight of one or more substances from the group of builders, acidifying agents, chelate complexing agents, plaque-inhibiting polymers or non-ionic tensides as well as 0 to 50% by weight of one or more adjuvants and/or fillers.

  • Publication number: 20040029764
    Abstract: Detergent portions containing at least one detersive formulation wholly or partly contained in a dimensionally stable hollow body having an enclosure that wholly or partly surrounds the detersive formulation, the enclosure being formed of an uncompressed material that can disintegrate under laundering, cleaning, or washing conditions and that gives the hollow body dimensional stability, and optionally, the dimensionally stable hollow body having one or more means forming one or more compartments therein.

  • Publication number: 20030186828
    Abstract: The invention relates to detergent or cleanser tablets, which have at least one cavity and whose content of non-ionic surfactants ranges from 5 to 25 wt. % with regard to the tablet. In multi-phasc tablets, it is sufficient to add an appropriate material to the mixture that forms the phase containing the cavity. The invention also relates to a method for producing recessed tablets.

  • Publication number: 20020010123
    Abstract: Claimed are laundry detergents and cleaning products which comprise customary ingredients and, characteristically, further comprise an active substance preparation which has been compounded with an LCST substance. By means of compounding with an LCST substance it is possible to incorporate active substances which, in a washing or cleaning process which passes through one or more temperature stages, are released only after a heat treatment, e.g., only in a rinse cycle.
