Example 2: Concentration of the Solvent in the Second Component

[0114] To adjust the appropriate concentration of the solvent in the second component, different concentrations have been used as in the table below. The resulting mixture was then evaluated for its appearance, i.e. its spraying potential. The perfume oil was Violet Spa. Also, the perfume oils Nature Pine, Pink Bloom, Provence, Aquafresh and Lemon Explosions were used in the same concentration. The preferred concentration of the solvent was found to be 15.5 to 35 wt.-%.

[0116] 12 g portions of mixtures of component 1 and component 2 (as in the table above) were prepared in the speed mixer. Different mixing ratios of component 1 and component 2 were applied to achieve the below mixtures A to G.

[0117] The stability of the resulting gels was evaluated by rheological measurements. The viscosity was constantly measured at {dot over (y)}=10 ms.sup.−1, τ=6.4 Pa. The mixtures were mixed in a separate container and then applied onto the rheometer. After a short waiting time, the measurement was conducted. The rheometer was tempered to 25° C. The measured value was noted as soon as a constant value was obtained. The below values are averages of a triplicate measurement.

Example 5: Adhesion Tests

[0120] First field experiments indicated that the major part of the formulation is lost with the first flush. Any residue left afterwards remains for a longer time period in the toilet. Consequently, the adhesion of the spray formulations was investigated in a funnel in order to quantify its residue after a first rinsing. Thereby, the combinations of different spray formula could be investigated and the most stable compositions could be determined.

[0121] A glass funnel (inlet: d=10 cm, h=8 cm; outlet: d=7 mm, l=10 cm) was filled with cold crane water (2×300 mL), emptied and allowed for one minute to drain. Prior to spray experiments, it was weighed. Then, the formulations H-K (Example 2) were filled into identical pump flasks and sprayed push by push vertically into the funnel with ratios according to the below table. The film was allowed to form over a period of 60 seconds, while its weight was monitored. Then, the funnel was purged with cold crane water (1×300 mL). Residual water was allowed to drop from the funnel for 60 seconds and the funnel was weighted immediately. All results have been measured as triplicates and are summarized below:

[0122] The most stable formulations were no.s 9 (89.3% adhesion, 44.3% SLES, 13.3% EtOH, 3.3% perfume oil), 7 (78.8% adhesion, 40.3% SLES, 10.0% EtOH, 2.5% perfume oil), 8 (74.1% adhesion, 36.2% SLES, 6.7% EtOH, 1.7% perfume oil), 3 (72.9% adhesion, 42.7% SLES, 13.3% EtOH, 1.7% perfume oil) and 1 (67.5% adhesion, 36.0% SLES, 10.0% EtOH, 2.5% perfume oil).

Example 6: Sensory Testing

[0123] In order to determine the most cost efficient perfume oil dosage, a gel was prepared and evaluated with varying perfume oil concentrations. The gels were prepared according to the below table. All samples were produced by mixing the components in containers standardized for all samples. All resulting gels had the same surface. A sensory evaluation was performed in rooms (2.5 m.sup.3) without ventilation. 18 non-professional panellists evaluated the rooms blindfolded in random order and rated the fragrance intensity.

TABLE-US-00008 Sample SLES Ethanol Perfume oil Water 1 38.50 10.00 5.00 46.50 2 38.50 10.00 3.75 47.75 3 38.50 10.00 2.50 49.00 4 38.50 10.00 1.25 50.25 5 38.50 10.00 0.00 51.50

[0124] Comparing the results and considering a cost-efficient approach. a perfume oil dosage of 2.5-5% has been adjudged to be most convenient:

[0125] The gel (24.00 g) was prepared in a 90 mL cup with a perfume oil concentration of 0.00%. 1.25%. 2.50%. 3.75% and 5.00%. The gel was covered with water (50 mL). After one minute. the water was decanted and disposed. while the cup was placed on a toilet tank in a closed cabin (2.5 m.sup.3). After 60 minutes. 18 non-professional panelists evaluated the cabins blindfolded in random order and rated the fragrance intensity on a scale of 0=below odour threshold to 9=very intensive. The blank feed could be distinguished highly significantly from all other samples. The difference between 1.25% and 5.00% perfume oil was very significant and the difference between 1.25% and 3.75%. as well as between 2.50% and 5.00% is rated as a tendency.
