Low interfacial tension in the thickened liquid compositions for cleaning hard surfaces allows the compositions to penetrate into the dirt and then lift them with solid surface�STI, to be suspended in the washing solution providing improved removal of oily contaminants and/or particles of oily contaminants. Interfacial tension is measured in accordance with the method described in the patent application WO 02/02724, pp. 9-11.

A method of determining the treatment efficiency of undiluted

The cleaning efficiency can be evaluated using the following test methods.

On horizontal surfaces

Kitchen and bathroom tile (ceramic, enamel or stainless steel) is prepared by applying to them a representative fatty or oily/particulate in form - artificial contamination with subsequent aging (2 hours at 130°C) contaminated tiles. The test composition was evaluated by applying small quantities of the product (for example, 5 to 10 ml) directly on the dirty tile under test and allowing the composition to act for some time (e.g. 1 minute). A test composition is subsequently removed from the said tiles by wiping the composition or wash tiles. The cleaning efficiency evaluated by measuring the number of cycles necessary to obtain a clean surface compared to the reference. The result, i.e. the number of cycles to test�position is compared with the result of the reference composition. Alternatively, the cleaning efficiency can be evaluated either by visual classification of tiles, or by using the colorimeter can also meter® Gloss. Visual classification can be performed by a group of experts with the use of scoring units (PSU). To assess the benefits of the purification efficiency of this composition can be applied PSU-scale ranging from 0, meaning no noticeable difference in the efficiency of purification in comparison with the reference composition, to 4, indicating a marked difference in the treatment efficiency compared to the reference composition.

Test PA gloss under conditions of pollution

The gloss test performed with a mixture of dirt, which consists of a mixture of relevant consumer contaminants such as oil, solid particles, pet dander, sugar, etc. Black glossy ceramic tiles contaminate the mixture of contaminants and purify the thickened liquid composition(s) for cleaning hard surfaces and analyze the results using the classification as described below.

Classification on the absolute scale:and on a scale PSU:
0 = as new /no streaks and/or film0 = don't see the difference
1 = very light streaks and/or film1 = I think that there is a difference
1 = light streaks and/or film2 = I am sure that there is a small difference
3 = light to moderate streaks and/or film3 = I am sure that there is a difference
4 = moderate streaks and/or film4 = I am sure that there is a big difference
5 = moderate/strong streaks and/or film
6 = strong streaks and/or film
