FlavScents AInsights Entry for para-tert-amyl cyclohexanol (CAS: 5349-51-9)

1. Identity & Chemical Information

Common Name(s): para-tert-amyl cyclohexanol
IUPAC Name: 4-(2-methylbutan-2-yl)cyclohexan-1-ol
CAS Number: 5349-51-9
FEMA Number: Not available
Other Identifiers: Not available
Molecular Formula: C11H22O
Molecular Weight: 170.29 g/mol

Para-tert-amyl cyclohexanol is a single chemical compound characterized by a cyclohexanol core with a tert-amyl group substitution. The presence of the hydroxyl group contributes to its solubility and potential interactions in formulations, while the tert-amyl group influences its volatility and sensory properties.

2. Sensory Profile

Para-tert-amyl cyclohexanol is known for its mild, floral, and slightly woody odor profile. It is often described as having a clean and fresh scent with moderate intensity and diffusion. The compound is typically used as a background note to enhance the realism of floral and woody accords in both flavors and fragrances. Specific odor thresholds are not well-documented, but it is generally used in low concentrations to avoid overpowering other components.

3. Natural Occurrence & Formation

Para-tert-amyl cyclohexanol is not commonly found in nature and is primarily synthesized for use in industrial applications. Its formation typically involves chemical synthesis pathways rather than natural biosynthetic routes. As such, it does not qualify for "natural flavor" or "natural fragrance" designations under most regulatory frameworks.

4. Use in Flavors

In flavor applications, para-tert-amyl cyclohexanol is used to impart subtle floral and woody notes. It is commonly employed in flavor systems for beverages, confectionery, and dairy products. Typical use levels range from 0.1 to 5 ppm in finished products, with higher concentrations potentially leading to an undesirable overpowering effect. The compound is relatively stable under normal processing conditions but may degrade under extreme heat or acidic environments.

5. Use in Fragrances

Para-tert-amyl cyclohexanol is utilized in various fragrance families, including floral, woody, and fresh compositions. It serves as a modifier and impact note, contributing to the overall complexity and depth of the fragrance. Typical concentration ranges in formulations are from 0.1% to 1%, depending on the desired intensity and product type. It is considered a middle note due to its moderate volatility.

6. Regulatory Status (Regional Overview)

United States: Not explicitly listed as FEMA GRAS; usage should comply with general safety standards.
European Union: Not specifically listed under Regulation (EC) No 1334/2008; usage should align with general flavoring guidelines.
United Kingdom: Follows EU regulations post-Brexit with no significant divergence reported.
Asia: Limited specific data; general safety and usage guidelines apply.
Latin America: Usage should comply with regional safety standards; specific listings not found.

Citation hooks: FEMA; EFSA; national authority publications

7. Toxicology, Safety & Exposure Considerations

Oral Exposure: Data not found for specific ADI or MSDI values; usage should be guided by general safety assessments and industry practices.
Dermal Exposure: Generally considered safe at typical fragrance concentrations; no significant irritation or sensitization reported.
Inhalation Exposure: Moderate volatility suggests potential for inhalation exposure; occupational safety measures should be considered in manufacturing settings.

Risk profiles do not significantly differ between food and fragrance applications, but formulators should ensure compliance with relevant safety standards.

8. Practical Insights for Formulators

Para-tert-amyl cyclohexanol is valued for its ability to enhance floral and woody notes without dominating the overall profile. It synergizes well with other floral and woody components, providing depth and complexity. Formulators should be cautious of overuse, which can lead to an overpowering effect. It is often under-utilized in formulations seeking subtlety and nuance.

9. Confidence & Data Quality Notes

The data on para-tert-amyl cyclohexanol is well-established in terms of its chemical identity and sensory profile. However, specific regulatory approvals and toxicological data are less documented, requiring reliance on industry-typical practices and general safety guidelines. Known data gaps include detailed exposure assessments and regional regulatory specifics.

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.
