The paper presents the results of testing the performance parameters of mixtures of biosurfactants from the group of sophorolipids and alkylpolyglycosides with different alkyl chain lengths. In order to determine the synergistic and antagonistic effects in two-component surfactant systems, research was carried out to determine the performance parameters determining their use in washing preparations, such as foam height (FH) and foam stability (FS) and wetting angle analysis (CA). The results are presented in tables 3, 4 and 5. Determination of the content of the active substance in the raw material samples was carried out using the method of refractometric determination of the refractive index. Both synergistic and antagonistic effects were found. On the basis of the obtained test results, the highest synergistic effect of performance parameters was obtained for the mixture of biosurfactants from the group of sophorolipids and the alkylpolyglycoside D-glucopyranose, oligomer, C10-16-alkylglycosides. In this case, the synergy occurred for all performance parameters FH (14%), FS (28%) and CA (46%). The synergistic effects were used to design a concentrated formulation of a cleaning agent in the food industry. The planned experiment method was used in order to obtain an optimal solution in terms of ensuring the appropriate level of cleaning efficiency. A twenty-two-point experiment plan was developed based on the Scheff model in order to optimize the composition in terms of obtaining the operational parameters of the mixture constituting the formulation's framework assumed in the optimization criteria. Optimization criteria were determined on the basis of studies of commercially available analogues. Thanks to the use of formulations of raw materials exhibiting synergistic effects in the design of the frame, the foam height and stability higher than those specified in the optimization criteria were obtained.
