摘要： Toilet bowl detergent compositions, preferably blocks of the "in-tank" or "rim-block" types, contain a cleaning system comprising: detergent surfactant of the amphoteric type, preferably zwitterionic, more preferably one that contains a carboxylate group and a cationic group, and even more preferably a fatty acid amidoalkylene betainc, and polycarboxylate chelating agent, preferably, citric acid, or similar polycarboxylic acid, are combined with some means of creating the desired concentration of the cleaning system in the toilet bowl water, preferably by means of blocks with a dissolution retarding system, preferably with the dissolution retarding system comprising a combination of water soluble cellulosic polymer, more preferably hydroxyethyl cellulose or hydroxypropyl cellulose and, polyethylene glycol containing polymer, any perfume present being selected to be mostly hydrophobic. The compositions have a pH, in use, of from about 4 to about 9 and the blocks are preferably extremely homogeneous. Processes for keeping toilet bowls clean are disclosed.
