Abstract
Analysis of fifteen volatile organic compounds previously associated with laundry malodour has been investigated using headspace solid phase microextraction gas chromatography–mass spectrometry. Limits of detection (all determined on a 25cm2 area of fabric) ranged from a low of 0.4ng (for guaiacol) through to a high of 28ng (for 3-methylindole) on cotton; values on polyester ranged from a low of 0.7ng (for dimethyl trisulfide) through to a high of 37ng (for 3-methylindole); and, values on terry-towel ranged from a low of 1.7ng (for guaiacol) through to a high of 157ng (for ethyl benzene). There was a lack of correlation between the level of malodour and the occurrence of any of the VOCs detected; it could be that other compounds not evaluated in this study are responsible for malodour or it could be a collaborative effect of the various compounds studied.
