AInsights Entry for Cedrenol (CAS: 28231-03-0)

1. Identity & Chemical Information

Cedrenol is a sesquiterpene alcohol commonly used in the fragrance industry. Its IUPAC name is (1S,2R,4S,4aR,8aS)-1,2,4-trimethyl-4a-(propan-2-yl)-decahydronaphthalen-1-ol. The CAS number for cedrenol is 28231-03-0. While it does not have a FEMA number, it is recognized in various fragrance and flavor databases. The molecular formula of cedrenol is C15H26O, with a molecular weight of 222.37 g/mol. Cedrenol's structure includes a hydroxyl group, contributing to its odor profile, which is characterized by woody and cedar-like notes.

2. Sensory Profile

Cedrenol is known for its distinctive woody, cedar-like aroma, often described as warm and slightly balsamic. It is used to impart a natural, woody character to fragrances and flavors. The intensity of its odor is moderate, making it suitable as a background note or modifier in complex formulations. While specific taste and odor thresholds are not well-documented, cedrenol is typically used in low concentrations due to its potent aroma.

3. Natural Occurrence & Formation

Cedrenol naturally occurs in the essential oils of various coniferous trees, particularly those in the Cupressaceae family. It is often found in cedarwood oil, where it contributes to the oil's characteristic scent. The formation of cedrenol in nature is primarily through the biosynthesis of sesquiterpenes in plant tissues. Its presence in natural sources qualifies it for use in products labeled as "natural fragrance" or "natural flavor."

4. Use in Flavors

In flavor applications, cedrenol is used to impart woody and earthy notes, often in conjunction with other terpenes to create complex profiles. It is commonly found in flavor categories such as spice, herbal, and woody. Typical use levels in finished food or beverage products range from 0.1 to 5 ppm, depending on the desired intensity and product type. Cedrenol is relatively stable under normal processing conditions but may degrade under extreme heat or acidic conditions.

5. Use in Fragrances

Cedrenol is a versatile component in the fragrance industry, used in a variety of fragrance families including woody, oriental, and fougère. It serves as a base note, providing depth and warmth to compositions. Typical concentration ranges in perfumes and personal care products are between 0.1% and 1%. Cedrenol's moderate volatility allows it to contribute to both the middle and base notes of a fragrance.

6. Regulatory Status (Regional Overview)

In the United States, cedrenol is not specifically listed by FEMA but is used under general GRAS guidelines for flavoring substances. In the European Union, it is regulated under Regulation (EC) No 1334/2008, with no specific restrictions noted. The United Kingdom follows similar guidelines post-Brexit. In Asia, including Japan and China, cedrenol is used in compliance with local flavor and fragrance regulations. In Latin America, countries like Brazil and those in MERCOSUR have no specific restrictions on cedrenol, but general safety and labeling requirements apply.

7. Toxicology, Safety & Exposure Considerations

Cedrenol's safety profile is generally favorable, with low toxicity reported in standard tests. For oral exposure, no specific ADI or MSDI values are available, but it is used within industry-typical limits. Dermal exposure in fragrance applications shows low irritation potential, and it is not a known sensitizer, aligning with IFRA guidelines. Inhalation exposure is considered safe at typical use levels, with no significant occupational hazards reported.

8. Practical Insights for Formulators

Cedrenol is valued for its ability to impart a natural woody character to both flavors and fragrances. It synergizes well with other terpenes and woody notes, enhancing the overall complexity of a formulation. Formulators should be cautious of overuse, as its potent aroma can dominate a blend. It is often underutilized in formulations seeking a subtle, natural woodiness.

9. Confidence & Data Quality Notes

The data on cedrenol is well-established, particularly in fragrance applications. While specific numeric thresholds for flavor use are not extensively documented, industry practices provide reliable guidance. Some regulatory ambiguities exist due to the lack of specific listings, but harmonized assumptions generally apply.

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.
