<p>The disclosure relates to a toilet cleaning block comprising perfume, at least one alkylbenzene sulfonate and at least one olefin sulfonate, wherein the block comprises one or more antimicrobial active ingredients and no more than 2.5 wt. % nonionic surfactants and is shaped in a rolling machine or press to form a spherical object, and wherein the antimicrobial active ingredient is a chlorine-containing antimicrobial active ingredient. These toilet blocks do not swell and, because of their round shape, they always display a minimum surface area. They are therefore flushed away evenly, so that the original shape is retained even after many flushes. Also disclosed is a method of manufacturing a rotationally symmetrical toilet cleaning block.</p> |
