FlavScents AInsights Entry for Muguet Carbinol (CAS: 103-05-9)

1. Identity & Chemical Information

• Common Name(s): Muguet Carbinol
• IUPAC Name: 3,7-Dimethyl-1-octen-3-ol
• CAS Number: 103-05-9
• FEMA Number: Not available
• Other Identifiers: FL number not available; CoE number not available; IFRA reference not available

Muguet carbinol is a monoterpenoid alcohol characterized by its floral and green odor profile. The presence of the hydroxyl group contributes to its solubility in alcohols and its moderate volatility, which is significant for its role in fragrance formulations. The structure-odor relationship is primarily influenced by the unsaturated bond and the methyl branching, which enhance its floral character.

2. Sensory Profile

Muguet carbinol is known for its delicate lily-of-the-valley (muguet) scent, which is fresh, floral, and slightly green. It is often described as having a moderate intensity with good diffusion, making it suitable for use as an impact note in fragrance compositions. The odor threshold is not clearly reported, but it is typically used in low concentrations due to its potent aroma.

In flavor applications, muguet carbinol is less common but can impart a subtle floral nuance when used judiciously. It serves primarily as a background realism enhancer rather than a primary flavor note.

3. Natural Occurrence & Formation

Muguet carbinol is not commonly found in nature and is primarily synthesized for use in perfumery. It does not have significant natural sources and is not typically associated with natural flavor or fragrance designations. Its synthesis involves the chemical modification of terpenes, which are abundant in essential oils.

4. Use in Flavors

Muguet carbinol is occasionally used in flavor formulations to impart a floral note, particularly in confectionery and beverage applications. Its functional role is to provide a subtle floral background that enhances the overall complexity of the flavor profile.

Typical use levels in finished food or beverages are not well-documented, but industry estimates suggest low ppm levels (1-5 ppm) due to its potent aroma. It is relatively stable under normal processing conditions but may degrade under high heat or acidic conditions.

5. Use in Fragrances

In perfumery, muguet carbinol is a valuable component in floral fragrance families, particularly those aiming to replicate the scent of lily-of-the-valley. It acts as a modifier and impact note, contributing to the top and middle notes of a fragrance composition.

Typical concentration ranges in perfumes are from 0.1% to 1%, depending on the desired intensity and character of the fragrance. Its moderate volatility allows it to blend well with other floral and green notes, enhancing the overall bouquet.

6. Regulatory Status (Regional Overview)

• United States: Muguet carbinol does not have a specific FEMA GRAS status for flavor use. Its use in fragrances is not restricted by the FDA.
• European Union: Not explicitly listed under Regulation (EC) No 1334/2008 for flavor use. Its use in fragrances is subject to general safety assessments.
• United Kingdom: Follows EU regulations post-Brexit with no specific divergence reported.
• Asia: Limited specific regulatory information available; generally follows international safety standards.
• Latin America: No specific regulatory data available; typically aligns with international guidelines.

7. Toxicology, Safety & Exposure Considerations

• Oral Exposure: Data not found for ADI or MSDI. Use in flavors is minimal, suggesting a low risk of oral exposure.
• Dermal Exposure: Generally considered safe for use in fragrances, with no significant reports of irritation or sensitization. IFRA standards should be consulted for specific restrictions.
• Inhalation Exposure: Moderate volatility suggests potential for inhalation exposure, but no specific occupational hazards reported.

Overall, the risk profile for muguet carbinol is low, with no significant differences between food and fragrance applications.

8. Practical Insights for Formulators

Muguet carbinol is valued for its ability to impart a fresh, floral character reminiscent of lily-of-the-valley. It synergizes well with other floral and green notes, enhancing the complexity and realism of fragrance compositions. Common pitfalls include overuse, which can lead to an overpowering scent, and instability under extreme conditions.

Formulators should consider its moderate volatility and potential interactions with other ingredients to optimize its impact.

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.
