In recent years, people’s awareness of changes in body odor associated with aging has increased, and interest in odor etiquette has increased. The author have so far conducted research on changes in body odor in women with aging and in the course of further awareness surveys, it became clear that many women felt that their scalp odor had changed with age. However, although research on scalp odor has been conducted, research on changes in scalp odor with age has not made much progress. Therefore, in this study, the author evaluated the scalp odor of women in their tens to 50s, and investigated changes in women’s scalp equipment with aging. In the experiment, the researchers used many compounds, for example, 5-Hexyldihydrofuran-2(3H)-one (cas: 706-14-9Recommanded Product: 706-14-9).
5-Hexyldihydrofuran-2(3H)-one (cas: 706-14-9) belongs to esters. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.
