Abstract

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.

Kurzfassung

In der Untersuchung wurden die Herstellungsstechnologie, die antibakteriellen, physikalisch-chemischen und die funktionellen Eigenschaf-ten von fortschrittlichen und umweltfreundlichen Produkten für die Hygiene in Toiletten behandelt. Bei dem Wirkstoff mit antibakteriellen Eigenschaften, der den in dieser Studie verwendeten Formulierungen zugesetzt wurde, handelt es sich um Humulus lupulus-Extrakt (Hopfendoldenextrakt), der unter überkritischen Bedingungen mit CO2 erhalten wurde. Es wurde angenommen, dass der Extrakt die antibakterielle Aktivität der Produkte verbessern würde, ohne ihre Anwendungseigenschaften zu beeinträchtigen. Die Zugabe eines 0,1 %-igen Hopfendoldenextrakts zu den untersuchten Formulierungen hatte auf S. aureus einen antibakteriellen Effekt, wohingegen kein derartiger Einfluss auf E. coli festgestellt werden konnte. Darüber hinaus wurde festgestellt, dass ein höherer Extraktgehalt die Viskosität des Produkts verstärkt und gleichzeitig die Auflösungszeit in Wasser verlängert und die Adhäsion an festen Oberflächen erhöht. Diese Eigenschaften sind aus der Sicht der Funktion derartiger Präparate sehr vorteilhaft.
