ABSTRACT:
A cleansing composition is disclosed that is particularly suited for compaction into tablet form, and comprises a phosphate salt, an optionally added silicate salt, such as a metasilicate and at least one perborate salt, wherein at least a portion of the perborate salt component is present as a compacted, granulated mixture with from about 0.01% to about 0.70% by weight of the perborate salt, of a polymeric fluorocarbon. Preferably, the perborate salt includes sodium perborate monohydrate and anhydrous sodium perborate, and polytetrafluoroethylene comprises the polymeric fluorocarbon used to prepare the granules.
When present, the silicate salt is preferably utilized within a particle size ranging from about 1 to about 25 microns. The silicate aids disintegration and assists in mechanical cleaning, when the composition is prepared in tablet form for use as a denture cleanser.
The use of the perborate granules reduces the difficulty of compacting the composition to form tablets, without impeding the operation and activity of the tablets as effervescent cleansers.
