Bars are typically solids in bar form, but may also be other solid shapes such as circular or oval.

[Brief explanation of the drawing]

[0127] [Figure 1] A figure showing the cleaning performance results of compositions tested that do not conform to the present invention. [Figure 2] A figure showing the cleaning performance results of the tested compositions according to the present invention.

[0128] Examples: The rhamnolipid was prepared as described in European Patent No. 3023431.

[0129] The sophorolipid used is REWOFERM SL ONE, manufactured by Evonik, and has a lactone-to-acid ratio of 40:60.

[0130] Glucolipids were produced via fermentation according to Example 2 of International Publication No. 2019154970.

[0131] Example 1: Cleaning performance of hard surface cleaning compound This example demonstrates the synergistic effect of sophorolipids and rhamnolipids in delivering the cleaning performance of hard surface cleaning formulations.

[0132] The exemplary formulations listed in the table below were prepared according to the following protocol: First, the measured amount of water was introduced into a glass beaker of appropriate size. Then, the remaining components (except sodium hydroxide) were added at room temperature while vigorously stirring. The order of addition to the solution is not important, so the components were not added in a specific or uniform order. Finally, any remaining amount of water was introduced to ensure the desired concentration of the components. All components were mixed using a magnetic stirrer, and the pH of the solution was adjusted to 7.5 by adding sodium hydroxide. The mixture was then stirred for 5 minutes to ensure a homogeneous solution. The exemplary compositions were readily pourable and remained stable at room temperature for extended periods.

[0133] Three formulations were prepared according to the method described above: Among the other components, reference formulation 1, which contained rhamnolipids, was subsequently used as a control formulation. Among the other components, sophorolipid was included in Reference Formulation 2, which was subsequently used as a second control formulation. Among the other components, test formulation 1 contained a mixture of rhamnolipids and sophorolipids, which helped to visualize the synergistic effect between rhamnolipids and sophorolipids. [Table 1]

[0134] Next, the cleaning performance of test formulation 1 was evaluated against the two reference formulations mentioned above. The procedure used to evaluate cleaning performance is described in the following test protocol.

[0135] The cleaning performance tests were conducted according to an internal testing methodology adapted from the recommendations of the German Cosmetic, Toiletry, Perfumery and Detergent Association (IKW): "IKW Recommendation for the Quality Assessment of the Product Performance of All-Purpose Cleaners 2014" (IKW Test Protocol). The principle of the test was to evaluate the cleaning power of the tested formulation by assessing its effectiveness in removing stubborn stains accumulated on melamine tiles. White melamine tiles (referred to here as test monitors) covered with a stubborn black stain composed of a mixture of fat and carbon black were purchased from the Center for Testmaterials BV (available under the name DM-40 Tile). To ensure high reproducibility of the results, all test monitors belonged to the same production batch and were conditioned in a climate chamber at 20°C for 24 hours before use.

[0136] To evaluate the cleaning performance of the prepared formulations, a test monitor was placed in a TQC Sheen Cleanability Tester (Model AB5000) and locked in place. At this point, one test monitor was placed in the cleanability tester, ensuring that each cleaning formulation was tested at least once on each of the four tracks of the cleanability tester. After drying, a 9cm × 4.5cm sponge was first moistened with tap water, and excess water was squeezed out of the sponge. Then, 10g of the test solution was loaded onto the sponge, and the sponge was attached to the cleaning arm of the cleanability tester. The cleanability tester was then operated and controlled to provide 35 cleaning cycles (and thus 70 linear strokes) on the test monitor. The stroke speed was 20 cycles per minute, and the test was performed at room temperature. After the 35 cleaning cycles were completed, the test monitor was removed from the Sheen tester, rinsed with tap water, and dried. The test was repeated several times to provide five iterations for each tested composition.

[0137] The treated test monitors were visually evaluated by five panelists who were asked to rank the cleaning effect achieved by each composition. The panelists ranked the cleaning effect on a scale from 0 to 10, where 0 represented no observed cleaning and 10 represented complete removal of dirt. For comparison purposes, each panelist was provided with a new, dirty test monitor representing no cleaning, as well as a fully cleaned test monitor representing a score of 10. In addition, the panelists were provided with an evaluation template according to the IKW test protocol to enable a more accurate assessment of the degree of cleaning. The scores for each of the tested compositions were totaled and averaged, and the results are reported in the table below. [Table 2]

[0138] As is readily apparent from the results reported in the table above, compositions containing a mixture of rhamnolipids and sophorolipids yield superior cleaning performance results compared to reference formulation 1. Furthermore, it is worth mentioning that reference formulation 2 could not be performed in the above test because the test sponge was unable to wipe horizontally over the surface of the test monitor, instead causing the holder to invert and fall. Thus, it became clear that the addition of rhamnolipids to hard surface cleaning formulations containing sophorolipids is necessary to provide the sponge with sufficient ability to glide over dirty surfaces. Subsequently, sophorolipids provide a cleaning formulation with a clear cleaning performance advantage compared to a cleaning formulation containing rhamnolipids as the sole surfactant. Therefore, the above examples provide evidence of a synergistic effect between rhamnolipids and sophorolipids when considering the overall properties of hard surface cleaning formulations.

[0139] Example 2: Cleaning performance of lipstick from skin using a simple composition Cleaning properties were determined by removing makeup from simulated skin substrates such as VITRO-SKIN® (IMS) using a scrubbing and cleansing device. This method is designed to test the cleaning effect of surfactant aqueous solutions, such as micellar water or facial toner, and can be used with types of makeup that can be completely dried on the described plate.

[0140] procedure: A sheet of VITRO-SKIN® (3 x 11 cm) is placed in a desiccator (equipped with 295 g of water and 52 g of glycerin) for no more than 24 hours. After hydration of VITRO-SKIN®, 4 mg of lipstick (SUPER STAY 24H, Maybelline New York) by the specified weight is applied to the sheet. The lipstick is allowed to dry for 1 hour. VITRO-SKIN® is fixed on a PMMA plate. The plate is fixed in the correct position, and 2.5 g of each test solution is prepared by diluting each test substance with water to 3% by weight. Each is applied to a cotton pad, and the cotton pad is attached to the sponge of the sliding carriage. After positioning the sliding carriage, the removal experiment is started. Cycles are set, with one cycle corresponding to one forward and backward movement. Speed: 10 cycles / minute, one cycle covers 160 mm. The number of cycles to remove all the lipstick is counted, and the results can be seen in Table 4.

[0141] Preparation of the test solution: All the test substances in Table 3 were diluted with water to a 3% by weight solution, and the pH was adjusted to 7. [Table 3] [Table 4]

[0142] As is readily apparent, a synergistic effect is achieved with the combination of both biosurfactants.
