The study discusses the technology of preparation, and antibacterial, physicochemical and functional properties of advanced eco-friendly products for maintaining hygiene in toilets. The active substance with antibacterial properties which was added to the formulations for the purpose of the study was  Humulus lupulus  (hop cone) extract obtained under supercritical carbon dioxide conditions. The assumption was that the extract would improve the antibacterial activity of the products without adversely affecting their functional properties. The addition of hop cone extract at the concentration of 0.1% to the tested formulations was found to produce an antibacterial effect against  S. aureus  bacteria, however, no such activity was demonstrated against  E. coli  bacteria. Moreover, an increase in the content of the extract was shown to enhance product viscosity, at the same time extending the time of dissolution in water and improving the adhesive power to solid surfaces. The properties are highly desirable for the functionality of products of this type.
