Description

[0107] The compositions of the inventive Examples 1, 2, 4, 6 and 7 and of the Comparative Examples 3 and 5 have been prepared in the following way:

[0108] Components a), b) and c) were mixed and heated from 50 to 75 C. until a homogeneous melt was obtained. Afterwards the homogeneous melt was cooled down to 25 C.

[0109] All gels of Examples 1, 2, 4, 6 and 7 are soft and deformable. They may easily be transformed into monodose formats or monodose products by either casting the homogeneous melt of the preparation process into a respective form or by cutting and/or pressing the gels in order to obtain the desired form.

[0110] The gels of Example 1 and 2 were further examined:

[0111] The gels of Example 1 and Example 2 show viscosity at a shear stress of 1000 Pa 1.5.Math.10.sup.7 Pa.Math.s and 8.8.Math.10.sup.7 Pa.Math.s, respectively. Viscosity characterization was performed using a rheometer Haake Mars III (Thermofisher Scientific) with a 35 mm plate-plate geometry at 20 C.

[0112] The gels of Example 2 and Example 4 were applied as monodose products to the ceramics of a toilet bowl and the adhesive properties of the gels have been tested. The gels could only be removed completely after approximately 150 and 130 flushing operations respectively which demonstrates that the gels of Example 2 and Example 4 possess very advantageous adhesive properties.

[0113] The inventive gel of Example 6 comprises 9.0 wt.-% of cocamidopropyl betaine which is an example of an amphoteric surfactant and therefore, the gel of Example 6 could be used for cleaning purposes or in cleaning applications.

[0114] The inventive gel of Example 7 comprises 21 wt.-% of C.sub.12/C.sub.14-alkyl-diglycolether-sulfate sodium salt which is an example of an anionic surfactant. This composition is an example of a gel with enhanced solubility and can be used among others in monodose systems for cleaning and scenting purposes in cleaning applications.
