Terpineol is a monoterpene alcohol mixture typically derived from the hydration of alpha-Pinene or Gum Turpentine. It is not a single, pure isomer but rather a stable combination of various isomers, including alpha-, beta-, and gamma-terpineol, with alpha-terpineol being its primary and most representative constituent. This product commonly appears as a colourless to pale yellow, viscous, transparent liquid, emitting a pleasant lilac-like fragrance complemented by pine, floral, or citrus notes.
