Antimicrobial Efficacy of Hygiene Rinsers under Consumer-Related Conditions

Antimikrobielle Wirksamkeit von Hygienespülern unter verbrauchernahen Bedingungen

Abstract

In domestic laundry, the question how to achieve a sufficient germ reduction gains importance since the trend towards lower washing temperatures and the incremental use of bleach-free liquid detergents does not ensure a sufficient hygiene by the means of temperature and bleach any longer. Hygiene rinsers as products being added to the rinse cycle offer further antimicrobial efficacy and seem to provide an adequate solution for this challenge. However, their regular application is debated due to the used ingredients and it is still unclear whether they are able to exhibit an additional antimicrobial efficacy. This study investigates the germ reduction by a supplementary use of hygiene rinsers under conditions that are close to the parameters found in the household to evaluate the benefit of these products for the hygienic reconditioning of laundry.

Kurzfassung

Mit dem Trend zu niedrigeren Waschtemperaturen und dem steigenden Gebrauch von bleichfreien Flüssigwaschmitteln kann eine ausreichende Hygiene über die Temperatur und Bleiche nicht mehr unbedingt gewährleistet werden, so dass bei Waschverfahren im Haushalt die Frage, wie eine ausreichende Keimreduktion zu erzielen ist, zunehmende Bedeutung erhält. Hygienespüler, die dem Spülgang zugegeben werden, bieten eine zusätzliche antimikrobielle Wirkung und könnten eine adäquate Lösung für dieses Problem sein. Ihre regelmäßige Anwendung wird jedoch wegen der verwendeten Inhaltsstoffe diskutiert, und es ist immer noch nicht geklärt, ob sie auch in der Waschmaschine einen messbaren Effekt zeigen. In dieser Studie wird die Keimreduktion durch zusätzlichen Gebrauch von Hygienespülern unter haushaltsnahen Bedingungen untersucht, um den Nutzen dieser Produkte für die hygienische Aufbereitung der Wäsche abschätzen zu können.
