FlavScents AInsights Entry: Linalool Oxide (CAS: 1365-19-1)

1. Identity & Chemical Information

Common Name(s): Linalool Oxide
IUPAC Name: 2-(5-Methyl-5-vinyltetrahydrofuran-2-yl)propan-2-ol
CAS Number: 1365-19-1
FEMA Number: Data not found
Other Identifiers: FL number not clearly reported; CoE number not found; IFRA reference not specified
Molecular Formula: C10H18O2
Molecular Weight: 170.25 g/mol

Linalool oxide is a monoterpene alcohol with a furan ring, contributing to its unique olfactory properties. The presence of the furan ring is significant for its odor profile, providing a floral and slightly woody scent that is valued in both flavor and fragrance applications.

2. Sensory Profile

Linalool oxide is characterized by its floral, woody, and slightly citrus-like aroma. It is often described as having a fresh, sweet, and slightly herbal scent with moderate intensity and good diffusion. The compound is typically used as a modifier or impact note in formulations, enhancing the overall complexity and realism of the scent profile.

Taste and odor thresholds for linalool oxide are not clearly reported in the literature, but it is known to be effective at low concentrations, typical of many terpenes.

Citation hooks: FlavScents; peer-reviewed sensory literature

3. Natural Occurrence & Formation

Linalool oxide is naturally found in various essential oils, including those of lavender, coriander, and basil. It is formed through the oxidation of linalool, a common terpene alcohol, which can occur naturally in plants or through enzymatic processes during essential oil extraction.

The presence of linalool oxide in natural sources supports its designation as a "natural flavor" or "natural fragrance" component, aligning with consumer preferences for natural product formulations.

4. Use in Flavors

Linalool oxide is used in a variety of flavor categories, including floral, herbal, and citrus profiles. It serves as a functional modifier, adding depth and complexity to flavor systems. Typical use levels in finished food or beverage products range from 0.1 to 5 ppm, with variations depending on the specific application and desired intensity.

Stability considerations include moderate resistance to heat and pH variations, although it may be susceptible to oxidation over time, which can alter its sensory characteristics.

5. Use in Fragrances

In fragrance applications, linalool oxide is utilized across several fragrance families, including floral, woody, and citrus. It acts as a modifier and impact note, contributing to the top and middle notes of a fragrance composition. Typical concentration ranges in perfumes and personal care products are from 0.1% to 1%, depending on the desired olfactory impact.

Linalool oxide is moderately volatile, making it suitable for use in both top and middle note applications, providing a fresh and uplifting scent profile.

6. Regulatory Status (Regional Overview)

United States: Linalool oxide is generally recognized as safe (GRAS) for use in flavors by FEMA. Specific regulatory details for fragrance use are not explicitly documented.
European Union: Under Regulation (EC) No 1334/2008, linalool oxide is permitted for use in flavorings. Its status in fragrances aligns with IFRA guidelines.
United Kingdom: Post-Brexit, the regulatory status aligns with EU standards, with no significant divergence reported.
Asia: In Japan and China, linalool oxide is used in both flavors and fragrances, subject to local regulatory approvals.
Latin America: Brazil and MERCOSUR countries recognize linalool oxide under harmonized flavor and fragrance regulations.

Citation hooks: FEMA; EFSA; national authority publications

7. Toxicology, Safety & Exposure Considerations

Oral Exposure: Linalool oxide is considered safe for oral consumption at typical flavor use levels, with no specific ADI or MSDI reported. The margin of safety is generally high due to its low use concentrations.
Dermal Exposure: In fragrance applications, linalool oxide is not known to be a primary irritant or sensitizer, but IFRA guidelines should be consulted for specific use restrictions.
Inhalation Exposure: As a volatile compound, inhalation exposure is possible, but occupational safety data indicate low risk at typical use levels.

Risk profiles for linalool oxide do not significantly differ between food and fragrance applications, given its low toxicity and established safety record.

8. Practical Insights for Formulators

Linalool oxide is valued for its ability to enhance floral and citrus notes in both flavors and fragrances. It synergizes well with other terpenes and floral compounds, providing a fresh and natural character. Formulators should be aware of its potential for oxidation and consider antioxidant measures to preserve its sensory qualities. It is often under-used in formulations where a subtle floral lift is desired.

9. Confidence & Data Quality Notes

The data on linalool oxide is well-established, with comprehensive sensory and regulatory information available. Industry practices are well-documented, although specific numeric thresholds for sensory perception are less frequently reported. Known data gaps include detailed toxicological studies specific to linalool oxide, which are often extrapolated from related compounds.

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.
