505 INFLUENCE OF MENSTRUAL CYCLE Volunteers 1, 19, and 20 were chosen as examples of response profiles, as they were the most significant and didactic to present the different responses encountered for the whole panel. Figures 2, 3, and 4 present the chromatograms obtained for these volunteers in each experimental time (initial, t 3h and t 6h ), which demonstrate the main differences in chromatographic profiles and fragment readings in the function of the menstrual cycle (5). Figure 5 shows the total scores of all m/z fragments generated from the volunteers’ skin’s volatile components. There was a slight tendency to form a response pattern during the luteal and menstrual phases, but the scores explanation was low (69% and 27%, respectively). There were many luteal and menstrual phase points mixed to the observed remainders. However, for those with a slight pattern, we observed in the loadings that fragments 91 and Figure 3. Chromatogram of volatile components of skin’s composition for volunteer nb.19. (A) initial experimental time, (B) after 3 h, (C) after 6 h. The black chromatogram corresponds to the follicular phase the blue chromatogram corresponds to the luteal phase the red chromatogram corresponds to the menstrual phase and the green chromatogram corresponds to the ovulatory phase.

506 JOURNAL OF COSMETIC SCIENCE 92 were the ones that demonstrated the response pattern for the profile found in the luteal and menstrual scores. Evaluating the aromatic composition, solvents, and environmental contaminants, we found these fragments in the following components: 91 = limonene and linalool 92 = limonene, linalool, cis-ß-ocimene, trans-ß-ocimene thujopsene, linalyl acetate α-cedrene, and α-pinene. According to Baydar et al. (1995), these components were considered as fragrance top and body notes (18). Figure 4. Chromatogram of volatile components of skin’s composition for volunteer nb.20.
