US Patent No. 12,146,119 B2 (Daniel Thomas Piorkowski, Christopher Michael Rodriguez, John Daniel Konikowski); Henkel AG & Co. KGaA has patented solid unit dose of a toilet cleaning composition. It contains anionic surfactant; virgin soap pellets; a carbonate or bicarbonate salt; an acid; and borax.

The virgin soap pellets comprise 18% to about 35% by weight of the toilet cleaning composition.

The compressed tablets can be used with a wand apparatus. The dissolvable formulations alleviate fear of flushing solid material and enables the consumer to clean the toilet and then see the solid dissolve during/after use, according to the patent. The formulations not only enable a product that has a good dissolution rate, structural integrity (so it does not crack during shipment or while in use), provides foaming (an indication of cleaning efficacy), and is resistant to significant humidity abuse, but also improves cleaning time compared to formulations without a boron compound, according to the patent literature.
