Abstract

Recently more consumers hang and dry their laundries indoor for various reasons. Under these slow drying conditions malodor was sometimes generated. Gas chromatography analysis showed the odorants were composed of medium-chain alcohols, medium-chain aldehydes, ketones, fatty acids, N-compounds and S-compounds. Especially, medium-chain fatty acids were confirmed to make up a characteristic and striking sweaty and sour odor. The malodor is supposed to be formed from sebum and soils by oxidative degradation as well as by metabolism of microorganisms. This study shows that a laundry detergent with an enzyme possessing high protease as well as bacteriolytic activity can prevent washed clothes from malodor generation during such a prolonged drying.

Kurzfassung

In Japan ist es heutzutage üblich, dass man seine Wäsche aus verschiedenen Gründen innerhalb des Hauses aufhängt und trocknet. Wegen der langsamen Trocknung kann es manchmal zur Geruchsbildung von halbtrockener Kleidung kommen. Durch eine gaschromatische Analyse wurde festgestellt, dass dieser Wäschegeruch mittelkettige Alkohole, Aldehyde, Ketone, Fettsäuren, N- und S-Verbindungen enthält. Insbesondere die mittelkettigen Fettsäuren zeigten sich dabei charakteristisch für den eigentümlichen sauren und schwitzigen Geruch. Es ist zu vermuten, dass dieser Geruch durch oxidative Zersetzung von Hautschmer oder Schmutz sowie durch den Stoffwechsel von Mikroorganismen erzeugt wird. Diese Studie zeigt, dass ein Waschmittel, welchem ein Enzym mit hoher Protease-Aktivität und Wirksamkeit der Bakteriolyse zugefügt ist, bei der Wäschetrocknung in Innenräumen die Geruchsbildung unterdrückt.
