Chemistry, Properties & Perfumer Guide
The Chemistry
Acetylated vetiver oil undergoes esterification of its natural alcohols (primarily vetiverols) with acetic anhydride. This semi-synthetic process increases volatility and alters polarity. The resulting acetates demonstrate improved stability compared to raw vetiver oil, while retaining key sesquiterpenoids like khusimol.
