FlavScents AInsights Entry: Hyssop Oil CO2 Extract
1. Identity & Chemical Information
Hyssop oil CO2 extract is a natural complex material derived from the plant Hyssopus officinalis. It does not have a specific CAS number due to its nature as a mixture rather than a single compound. This extract is obtained through supercritical CO2 extraction, which preserves the volatile components of the plant. It is commonly used in both flavor and fragrance applications due to its aromatic properties.

2. Sensory Profile
Hyssop oil CO2 extract is characterized by its herbaceous, camphoraceous, and slightly sweet aroma. It has a strong, penetrating scent with a warm, spicy undertone. The oil is often described as having a minty and earthy profile, contributing to its use as an impact note in formulations. The intensity of its aroma makes it suitable for use in small quantities to achieve the desired sensory effect.

3. Natural Occurrence & Formation
Hyssop oil is naturally sourced from the aerial parts of the Hyssopus officinalis plant, which is native to the Mediterranean region. The oil is formed through the extraction of volatile compounds present in the plant, primarily using supercritical CO2 extraction methods. This process is favored for its ability to capture the full spectrum of aromatic compounds, making it suitable for natural flavor and fragrance designations.

4. Use in Flavors
In flavor applications, hyssop oil CO2 extract is used to impart a herbal and slightly minty note. It is commonly found in herbal liqueurs, bitters, and certain confectioneries. The typical use levels in finished food products range from 0.5 to 5 ppm, depending on the desired intensity and the complexity of the flavor system. The oil is relatively stable under normal storage conditions but may degrade under prolonged exposure to heat and light.

5. Use in Fragrances
Hyssop oil CO2 extract is utilized in fragrance formulations for its unique herbal and camphoraceous scent. It is often included in aromatic and fougère fragrance families, contributing as a middle note that provides depth and complexity. Typical concentration ranges in perfumes are from 0.1% to 1%, depending on the desired olfactory impact. The oil's volatility allows it to blend well with other middle and top notes.

5a. Key Constituents (Typical)
The key constituents of hyssop oil CO2 extract include pinocamphone, isopinocamphone, and β-pinene. These compounds contribute significantly to the oil's characteristic aroma. The composition of the extract can vary based on the geographical origin of the plant, the time of harvest, and the specific extraction process used.

6. Regulatory Status (Regional Overview)
In the United States, hyssop oil is generally recognized as safe (GRAS) for use in flavors by FEMA. In the European Union, it is subject to the regulations outlined in Reg. (EC) No 1334/2008. The UK follows similar guidelines post-Brexit. In Asia, specific regulations may vary, with Japan and China having their own standards for natural extracts. In Latin America, countries like Brazil adhere to MERCOSUR regulations, which may include specific restrictions or allowances for natural extracts.

7. Toxicology, Safety & Exposure Considerations
For oral exposure, hyssop oil CO2 extract is considered safe within the typical use levels in food. However, due to the presence of pinocamphone, which can be neurotoxic in high doses, it is important to adhere to recommended concentrations. Dermal exposure in fragrance applications is generally safe, but it may cause irritation or sensitization in sensitive individuals. Inhalation exposure is typically low risk, but occupational safety measures should be observed during handling.

8. Practical Insights for Formulators
Hyssop oil CO2 extract is valued for its ability to impart a unique herbal note that can enhance both flavor and fragrance formulations. It synergizes well with other herbal and minty notes, but care should be taken to avoid overpowering the blend. Formulators should be cautious of its strong aroma, which can easily dominate a composition if overused.

9. Confidence & Data Quality Notes
The data on hyssop oil CO2 extract is well-established, particularly regarding its sensory profile and typical applications. However, there are gaps in specific regulatory details across different regions, and formulators should verify local regulations. Industry practices are generally consistent, but documentation may vary.

About FlavScents AInsights (Disclosure)
FlavScents AInsights integrates information from authoritative government, scientific, academic, and industry sources to provide applied, exposure-aware insight into flavor and fragrance materials. Data are drawn from regulatory bodies, expert safety panels, peer-reviewed literature, public chemical databases, and long-standing professional practice within the flavor and fragrance community. Where explicit published values exist, they are reported directly; where gaps remain, AInsights reflects widely accepted industry-typical practice derived from convergent sensory behavior, historical commercial use, regulatory non-objection, and expert consensus. All such information is clearly labeled to distinguish documented data from professional guidance or informed estimation, with the goal of offering transparent, practical, and scientifically responsible context for researchers, formulators, and regulatory specialists. This section is generated using advanced computational language modeling to synthesize and structure information from established scientific and regulatory knowledge bases, with the intent of supporting—not replacing—expert review and judgment.
