<p>A system (1) is described for cleaning and disinfecting a toilet (2) comprising a container (3) of a liquid composition (L), said container (3) being closed in a substantially fluid-tight manner; valve means (7) co-operating with an outlet opening (17) for said liquid composition (L), said outlet opening (17) being formed in the container (3) and operated at each flushing operation by the water introduced into the bowl (2) for delivering dosed amounts of the liquid composition (L); wherein the liquid composition (L) is stored in the container (3),.has a viscosity at 20 DEG ; C of from 25 to 500 mPa.s and comprises a) from 15 to 70% by weight of an oxidizing agent selected from the agents adapted to release a halogen or oxygen when contacted with water, and mixtures thereof; b) from 1 to 25% by weight of a cleaning agent comprising at least one surfactant selected from the group comprising the anionic, cationic, non-ionic or amphoteric surfactants compatible with the oxidizing agent, said cleaning agent being such as to form, in combination with the oxidizing agent, a liquid composition (L) capable of mixing with the flushing water introduced in toilet bowl (2) without forming hydration complexes or micelles during the flushing operations of said water; and c) an effective amount of at least one pH-stabilizing agent adapted to adjust the pH of the liquid composition (L) at a value such as to maintain the oxidizing agent substantially stable.</p> |
