  • the use pours into the suitable trays, into the dedicated compartment, or into the containers to be introduced directly into the basket, the detergent and other additives, such as for example fabric softener, bleach, antibacterial or antiscale agents.
  • the antiscale agent in particular, is a product which the user often forgets to introduce, since it performs a preventative action and hence does not give the user an immediate and practical confirmation, as may instead occur with the softener which makes washed items softer, or bleach which makes the laundry brighter, or dishwasher fragrance diffusers which remove unpleasant odours, or rinse aid which improves dishes polish. These substances cause effects which the user immediately detects with his/her senses and they encourage him/her to make constant use thereof.
  • a self-adhesive water softening composition which comprises:
  • the said self-adhesive water softening composition may be applied and adhered to a dry or wetted surface, especially an interior sidewall in an automatic laundry- washing machine, and wherein the said self-adhesive water softening compositions is retained adhered to the said surface following a plurality of operations of the automatic laundry washing machine.
  • the composition has been found to be sufficiently adhesive such that it can he retained in its placed locus.
  • the composition is located in the detergent dispensing drawer of automatic laundry washing machine.
  • composition of the invention has been found to have particularly beneficial performance in providing water softening in an automatic laundry washing machine
  • the composition is intended to provide a water softening benefit over a plurality of wash cycles.
  • a user can perform a number of wash cycles without the inconvenience of having to add a water composition to the automatic laundry washing machine.
  • this benefit is provided over around 10 wash cycles.
  • wash cycle in this context it is meant a complete washing program such as can be found on an automatic laundry washing machine; such as those cycles labeled "wool", “cotton”, “synthetics”. It is of course realized that this list is not exhaustive and that the list varies from country to country and from manufacturer to manufacturer. Of course it is also realized that sometimes a user of an automatic laundry washing machine sometimes runs the machine such that only a portion of a cycle is completed. Again, here the composition of the invention can still provide a benefit.
  • composition has been found to release a uniform amount of water softening composition in each wash cycle. This is beneficial in that a user obtains the correct amount of water softening level over a plurality of wash cycles without having to replace the composition.
  • composition has been found to provide its own clear visual signal (by the size of its presence) to a user for when it needs replacing.
  • composition has been found to be sufficiently adhesive such that it can be retained in its placed locus.
  • the composition is adhesive when wetted. This can be achieved by wetting the surface to which the composition is to be applied or by wetting the composition itself.
