RESUMO

The Substantivity study of the aromatic composition/fragrance on the skin in function of menstrual cycle is the big issue because of the scientific literature says, with no significant conclusions, which the sex hormones demonstrate wide physiologic effects in the skin and in the olfactory perception, particularly, in the ovulatory and luteal phases versus other ones of the menstrual cycle. The aim of this study was to investigate if the sex hormones influence on the olfactory perception and their physiologic effects in the skin might change the fragrance performance during the menstrual cycle. Thus it was employed a sensory evaluation and was defined the LMS scale (labeled magnitude scale) to score the fragrance intensity in the assessment. The stability test defined the best aromatic composition/fragrance to the experiment. The clinical study was conducted in four phases of the menstrual cycle (menstrual, follicular, ovulatory and luteal) and, each one, the perfume intensity was evaluated in 5 experimental times (initial, 1,5h, 3,0h, 4,5h and 6h) in parallel with the bioengineer measurement of the skin (transepidermal water loss, moisturizing and sebum content) and a man was considered a skin control in the experiment. The bioengineer measurement was no significant to influence the olfactory perception; however, the fragrance perception in the luteal phase was higher when the woman evaluated her skin and lower when she evaluated man skin in comparison to the other phases. In summary, the sex hormones influenced the olfactory perception in different phases of the menstrual cycle; however, the skin physiologic effects did not affect the olfactory perception probably and this issue helps to development fragrances and instigates to discover aromatic raw materials that influence woman behavior or even the sex attraction.
