Definitions

  • the washing composition within the container or receptacle part, or within a compartment thereof, need not be uniform.
  • a settable agent for example a gel, useful in a washing process, and then with a different material.
  • the first material could dissolve slowly in the washing process so as to deliver its charge over a long period within the washing process. This might be useful, for example, to provide immediate, delayed or sustained delivery of a softening agent in a clothes washing container or a receptacle part.
  • the two portions of the container can be welded—by means of a laser beam, say—into a single unit which cannot thereafter readily and without leaving visible traces be separated into body and cap in order to gain access to the contents.
  • the container, receptacle or closure may, for example, have raised portions moulded into its external surface.
  • an incuse pattern has a number of interesting possibilities. For example, it can help determine the time of release of the container's contents.
  • Such an incuse pattern design may include a container, for example of standard elongate form but with relatively thick walls. However a container or receptacle of any shape may be used. Around the centre section of the container base, or any other part of the container or receptacle, is moulded a number, for example an array, of thin-walled incuse panels. Once the container or receptacle has reached its intended destination, the thin-walled panels in the body quickly dissolve, leaving the body with a structure of holes, for example in the form of a grid.
  • Especially preferred secondary alkyl sulfates are the (2,3) alkyl sulfate surfactants of formulae:
  • Suitable builders are alkali metal or ammonium phosphates, polyphosphates, phosphonates, polyphosphonates, carbonates, bicarbonates, borates, polyhydroxysulfonates, polyacetates, carboxylates such as citrates and other polycarboxylates.
  • the builder is desirably present in an amount of up to 90 wt %, preferably 15 to 90 wt %, more preferably 15 to 75 wt %, relative to the total weight of the composition. Further details of suitable components are given in, for example, EP-A-694,059, EP-A-518,720 and WO 99/06522.
