ASSESSMENT OF THE EFFECTIVENESS OF THE WASHING PROCESS DEPENDING ON THE NATURE OF THE SURFACTANTS INCLUDED IN THE COMPOSITION

Today, developing effective formulas for cleaning products is a pressing issue, as major and leading suppliers of raw materials for household and industrial cleaning products have rapidly left the Russian market over the past few years. This situation has prompted domestic manufacturers of detergent components not only to develop analogues of the raw materials most in demand by manufacturers, but also to create detergents with more advanced and effective properties. The study examines detergent compositions developed on the basis of raw materials produced in Russia. Detergent compositions are complex multicomponent systems, but their main components are surfactants. For this reason, the study focused primarily on the selection and analysis of foaming components, as they are responsible for the main cleaning properties of the detergent. Ethylenediaminetetraacetic acid, produced in Russia, was chosen as the complexing component for all the compositions studied. To determine the cleaning efficiency of the analyzed compositions, a study was conducted on the wetting ability of test samples of cleaning compositions using a Wilhelmy plate and samples of standard-contaminated cotton fabric EMPA-106. In addition, the adsorption processes of the surface-active components included in the studied detergent compositions were analyzed, and the adsorption heat for each composition was determined. The results of the experiments made it possible to select detergent components that exhibit synergy with each other, as well as to conclude that raw materials produced in Russia have the necessary properties for successful use in detergent production technologies.
