  • Patent number: 4256599
    Abstract: A two layered cleansing tablet for the self-acting cleansing of dentures. The layers of the tablet disintegrate at controlled rates so that denture cleansing action is made more efficient and effective compared to single layered tablet structures. The present tablet employs sulfonic acid in the tablet layer which disintegrates in a first stage cleansing step and further employs ethylene diamine tetraacetate in both tablet layers. Improved denture cleansing action is achieved even with no increase in the total amount of active agents employed in a tablet.
