Abstract

It is known that decreasing temperatures in laundry can have a significant impact on the hygiene efficacy of laundering. This study used suspension tests to investigate the microbicidal effects of heat, detergent and activated oxygen bleach and their contributions to laundry hygiene. The results indicate that heat at 60°C contributes significantly to the microbicidal action, while detergent only has limited effects. Activated oxygen bleach strongly enhances the microbicidal action and thus has the potential to compensate for the loss of antimicrobial efficacy due to temperature decrease. This effect varied with the test strain and the temperature, and further work is needed to determine whether it is possible to achieve a hygiene effectiveness equivalent to that at 60°C across both fungal and bacterial strains.

Kurzfassung

Es ist bekannt, dass abnehmende Temperaturen beim Waschen einen signifikanten Einfluss auf die Wäschehygiene haben. In dieser Studie werden mittels Suspensionstests die mikrobizide Wirkung von Wärme, Waschmitteln und Aktivsauerstoffbleiche und die Beiträge dieser Bestandteile zur Wäschehygiene untersucht. Die Ergebnisse zeigen, dass Wärme von 60°C signifikant zur mikrobiziden Wirkung beiträgt, während das Waschmittel allein eine nur begrenzte Wirkung besitzt. Die aktivierte Sauerstoffbleiche verstärkt die mikrobizide Wirkung deutlich und ist daher imstande, den aufgrund einer Temperatursenkung entstehenden Verlust der antimikrobiellen Wirkung zu kompensieren. Dieser Effekt variiert mit Teststamm und Temperatur. Weiterführende Arbeiten sind notwendig, um festzustellen, ob eine hygienische Wirksamkeit erreicht werden kann, die gegenüber Pilzen und Bakterien zur der bei 60°C equivalent ist.
