A cleaning implement comprises an erodible foam substrate, such as a melamine foam substrate and a controlled release system comprising an active agent. The controlled release system comprises a component selected from the group consisting of a polymer matrix, a microcapsule, a particulate porous carrier, a complexing agent, a semi-permeable film and a combination thereof and the active agent is selected from the group consisting of a surfactant, a bleaching agent, a limescale reducing agent, a biocide, a solvent and a mixture thereof.

Cleaning implement with erodible foam substrate and controlled release system of active agent

A cleaning implement comprises a modified open-cell foam with a density in the range from about 5 to about 1,000 kg/mand with an average pore diameter in the range from about 1 &#x3bc;m to about 1 mm, comprising an amount in the range from about 1 to about 2,500% by weight, based on the weight of the unmodified open-cell foam, of at least about one water-insoluble polymer (b), selected from polystyrene, styrene copolymers, polybutadiene, butadiene copolymers, polyvinylesters, polyvinylethers, copolymers from (meth)acrylic acid with at least one (meth)acrylate, and polyurethanes, with the proviso that styrene-acrylonitrile-C-C-alkyl (meth)acrylate terpolymers, styrene-butadiene-n-butyl acrylate terpolymers, and styrene-maleic anhydride copolymers are excluded.

Cleaning implement comprising a modified open-cell foam

The present invention envisages a cleaning implement comprising a melamine foam preferably having a thickness of at least about 5 mm and a perfume source, processes for making them and methods for using them.
