The thermal behavior of lavender and sage essential oils (EOs) and also that of their main components (camphor and 1,8-cineole) were studied by thermogravimetry (TG) at different scan rates under inert gas atmosphere up to about 140 °C. All the samples investigated undergo a single-step evaporation starting from ambient temperature without evidence of side decomposition processes. On the basis of the onset temperatures (Ton) extrapolated from the TG curves, the following increasing stability trend is assessed: 1,8 cineole < sage < camphor 1,8-cineole

All the samples investigated undergo a single-step evaporation starting from ambient temperature without evidence of side decomposition processes. On the basis of the onset temperatures (Ton) extrapolated from the TG curves, the following increasing stability trend is assessed: 1,8 cineole < sage < camphor 1,8-cineoleFile in questo prodotto:
