TOILET BOWL CLEANER

摘要

The longevity of a cleaning block containing a high sudsing amine oxide surfactant (e.g., N,N-dimethyltetradecylamine oxide) is increased by also including in the block at least one higher molecular weight amine oxide (e.g., N,N-dimethyloctadecylamine oxide), at least one soap, and at least one water-soluble alkali metal salt so that the block (1) has a water-soluble alkali metal salt content of 15-60 % by weight and a surfactant content of 10-70 % by weight and (2) contains as the surfactant a mixture of (A) 10-60 % by weight of a soap component and (B) 90-40 % by weight of a non-soap component having an amine oxide content of at least 15 % and containing as the amine oxide ingredient a mixture of 0.1-10 parts by weight of the higher molecular weight amine oxide and one part by weight of the high sudsing amine oxide.
