Using THERMAL DESORPTION GAS CHROMATOGRAPHY for the identification of fragrance and other components in cosmetic products

Analytical conditions

Each sample tube was analyzed using TD-GC-MS under the conditions listed in Table 1.

Results and Discussion

Figure 2 shows a total ion chromatogram (TIC) obtained from the liquid soap sample. Despite the messy nature of this sample, clean chromatography has been obtained thus enabling easy data processing. The TurboMass software was used to examine the mass spectral data of each of the major components and to perform a library search to identify each of these. Figures 3, 5 and 7 show some typical mass spectra taken from the liquid soap chromatogram and Figures 4, 6 and 8 show the corresponding results from the spectral library search. Figures 9 to 15 show the total ion chromatograms, with annotated peak identities, for the remaining samples.

Conclusions

This note has described a simple means of identifying fragrance and other volatile compounds in cosmetic preparations without the need for tedious and lengthy sample extractions.
