terpeneless clove bud oil

Terpeneless clove bud oil is a processed essential oil obtained from the flower buds of Syzygium aromaticum, commonly known as clove. This oil is refined to substantially reduce terpene components while preserving the core spicy and warm aroma intrinsic to clove buds. It is identified under several synonyms, including caryophyllus aromaticus bud oil terpeneless and eugenia caryophyllata bud oil terpeneless. The oil is a clear to slightly yellow liquid characterized by a strong spicy odor and flavor reminiscent of fresh clove, which finds appreciation in both flavor and fragrance formulations. More detailed chemical information is catalogued under its PubChem entry. Terpeneless clove bud oil is principally derived through steam distillation of clove buds followed by terpene removal processes, enabling its use in applications sensitive to the presence of terpenes.

Terpeneless clove bud oil occurs naturally in the flower buds of the clove tree (Syzygium aromaticum). The removal of terpenes distinguishes it from typical clove bud oil, offering a less volatile, more refined material. This oil is employed primarily as a flavor and fragrance agent, imparting spicy, warm, and oriental notes in various consumer products. Its reduced terpene content makes it suitable for formulations where terpene-related instability or sensitization is a concern. The oil's utilization aligns with standards such as the IFRA (Global) code of practice, which governs fragrance ingredient safety and use levels in consumer applications to ensure regulatory compliance.

Terpeneless clove bud oil exhibits solubility in alcohol and limited solubility in water, with an estimated 98.28 mg/L solubility at 25 °C. Its reduced terpene content impacts volatility, typically resulting in a more stable aromatic profile compared to full terpene clove oil. The oil’s spicy odor and flavor derive from retained phenylpropanoid compounds, which contribute to its characteristic clove aroma. These properties influence its behavior in formulation, offering enhanced stability and suitability for inclusion in both aqueous and alcoholic matrices. The oil’s physical attributes facilitate its use in flavor and fragrance blends where controlled delivery of clove notes is desired.
