FlavScents AInsights Entry for Taylorione (CAS: 55304-00-2)

1. Identity & Chemical Information

Common Name(s): Taylorione
IUPAC Name: 1-(2,6,6-Trimethyl-1-cyclohexen-1-yl)pent-1-en-3-one
CAS Number: 55304-00-2
FEMA Number: Not available
Other Identifiers: Not available
Molecular Formula: C14H22O
Molecular Weight: 206.33 g/mol

Taylorione is a single chemical compound characterized by its cyclohexene ring and a conjugated ketone group. The presence of the cyclohexene ring contributes to its odor profile, which is often associated with woody and spicy notes. The ketone group is crucial for its reactivity and interaction with other fragrance and flavor compounds.

2. Sensory Profile

Taylorione is known for its distinctive woody and spicy odor, which can be described as reminiscent of cedarwood with a hint of pepper. The intensity of its scent is moderate, making it suitable for use as a background note in complex fragrance compositions. Its diffusion is relatively stable, providing a consistent olfactory experience over time. While specific taste and odor thresholds are not well-documented, it is typically used in concentrations that enhance the overall sensory profile without overpowering other components.

3. Natural Occurrence & Formation

Taylorione does not occur naturally in significant quantities and is primarily synthesized for use in flavor and fragrance applications. Its formation typically involves chemical synthesis pathways that incorporate cyclohexene derivatives and ketone functionalization. Due to its synthetic origin, taylorione is not classified under "natural flavor" or "natural fragrance" designations, which may influence its regulatory status and consumer perception.

4. Use in Flavors

Taylorione is utilized in various flavor categories, including savory and spice blends, where it serves as a modifier to enhance woody and spicy notes. Its functional role in flavor systems is to provide depth and complexity, often used in conjunction with other compounds to achieve a balanced profile. Typical use levels in finished food or beverage products range from 0.1 to 5 ppm, depending on the desired intensity and application. It is generally stable under typical processing conditions, though care should be taken to avoid excessive heat, which may degrade its aromatic properties.

5. Use in Fragrances

In the fragrance industry, taylorione is incorporated into woody and spicy fragrance families, often found in perfumes, colognes, and personal care products. It acts as a middle note, providing a warm, woody character that complements other fragrance components. Typical concentration ranges in formulations are from 0.05% to 0.5%, depending on the desired olfactory impact. Its volatility is moderate, contributing to its role as a middle note that bridges top and base notes effectively.

6. Regulatory Status (Regional Overview)

United States: Taylorione is not explicitly listed as FEMA GRAS, indicating formulators should verify its status for specific applications.
European Union: Under Regulation (EC) No 1334/2008, taylorione's use in flavors and fragrances should comply with general safety requirements, though specific FL number status is not available.
United Kingdom: Post-Brexit, the UK aligns closely with EU regulations, but formulators should confirm any divergence.
Asia: Regulatory status in Japan, China, and ASEAN countries is not clearly reported; local regulations should be consulted.
Latin America: Information on approval in Brazil and MERCOSUR is limited; formulators should verify compliance with regional standards.

7. Toxicology, Safety & Exposure Considerations

For oral exposure, specific ADI, TTC, or MSDI values for taylorione are not available, necessitating cautious use in flavor applications. Dermal exposure considerations include potential irritation or sensitization, though specific IFRA guidelines are not detailed. Inhalation exposure is generally low risk due to moderate volatility, but occupational safety measures should be observed. Risk profiles may differ between food and fragrance applications, emphasizing the need for context-specific safety assessments.

8. Practical Insights for Formulators

Taylorione is valued for its ability to impart woody and spicy notes, enhancing the complexity of both flavors and fragrances. It synergizes well with other woody and spicy compounds, though care should be taken to avoid overuse, which can lead to an overpowering scent. Common pitfalls include instability under high heat and potential regulatory challenges due to its synthetic nature. Formulators often underutilize its potential in creating balanced, nuanced profiles.

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.
