DESI and PADI are useful when determining the siloxane contents of anti-aging creams.
Tara Salter and colleagues present a preliminary study for a non-invasive in vivo investigation of personal care products on fixed fibroblast cells. They carried our mass spectrometry analyses of 13 molecules commonly used in personal care products, including organosiloxanes, with both PADI and DESI to determine the different sensitivities of the techniques.
