A total of 63 volunteers were recruited and selected with a stronger than normal underarm malodor, as determined by a trained odor panel. The volunteers were using bacterial sprays and placebo sprays in the underarm to verify the effect on the underarm odor. Odor analysis was done using hedonic value measurement by a trained odor panel, as well as GC/MS analysis. Cleaned and degassed PDMS patches were placed on the underarm skin of the volunteer for 4h and secured in place with a large cotton bandage. After sampling, the bandage was removed, patches placed into 2 mL borosilicate vials using clean tweezers and capped with a crimp camp with silicone septum.
The GC-MS analysis was carried out using the Agilent 7200 GC/QTOF equipped with robotic sampler system.
