Abstract:
1. A self-sticking cleansing block that disintegrates in a rinse liquid, the block consisting essentially of: 25% to 99% of a solid anionic surfactant for providing adherence to a surface; and 1% to 25% of a liquid component, wherein the cleansing block includes a non-ionic surfactant for increasing solubility of the block, wherein the block is not a gel, wherein the cleansing block is sticky such that the cleansing block may be attached directly to the surface in a position that is contacted by the rinse liquid, wherein all percentages are percent by weight of the total composition of the cleansing block; wherein the cleansing block has a stickiness as measured in a “Stickiness Test” of at least 50 grams such that the cleansing block can be held against a wall of a toilet or urinal under a flushing rim thereof and above a waterline thereof, by its own stickiness, and then remain at least in part stuck thereto even after two weeks of flushing of the toilet or urinal; and wherein the cleansing block has a hardness as measured in a “Hardness Test” of greater than 50 tenths of a millimeter of penetration.
