EXAMPLE 7

[0053] The composition in the form of tablets was added to clean water in the lavatory pan before using the toilet. All variants of the composition according to Examples 1-5 showed excellent results: the composition neutralized the odor from the toilet for 6-9 hours. The best, most unexpected effect was provided by the composition according to Example 6: with a single use, the tablet acted for almost 12 hours.

EXAMPLE 8

[0054] A study was conducted to confirm the RESULT of the technical solution. In particular, the total number of microorganisms in 1 m.sup.3 of test liquid volume was determined. Sampling was performed on nutrient agar such as meat-and-peptone agar, powder nutrient agar, or fishmeal extract agar. The cultures were incubated at 37° C. for 48±2 h, the number of colonies grown was counted and recalculated per 1 m.sup.3 of test fluid volume. Analysis of the test liquid before the application of the disinfectant solution according to the invention showed the presence of an average of 10-12 colonies of microorganisms per Petri dish. After treatment of the test liquid with the solution the absence of growth of pathogenic and opportunistic bacteria was recorded.

EXAMPLE 9

[0055] Flushing from the surface of the lavatory pan was carried out in 1, 3, 6, 9, and 12 hours after application of the tablet form according to the invention using sterile gauze napkins, 5×5 cm in size, soaked in the means according to the invention. The inner surface of the lavatory pan over the border of the convex meniscus of the test liquid was carefully wiped with a gauze napkin. Also flushing from the surface of the recesses of the upper inner part of the lavatory pan was performed in 1, 3, 6, 9, and 12 hours after treatment with the composition according to the invention. After sampling, a gauze napkin was placed in a wide-necked test tube or flask with saline and glass beads and shaken for 10 minutes. The liquid was injected deep into 2 Petri dishes with meat-and-peptone agar (0.5 ml each) and into 2 tubes with 0.5% sugar broth (1 ml each). The cultures were incubated at 37° C. for 48 hours. The lack of growth of pathogenic and opportunistic bacteria was recorded.

[0056] Therefore, the use of the disclosed tablets helps to remove odor (as result of presence of urea) from the waterless toilet (or the lavatory pan), due to the decomposition of urea and deodorizing and disinfecting effect of this composition, without having to flush.
