FlavScents AInsights Entry for (+)-Nerolidol (CAS: 142-50-7)

1. Identity & Chemical Information

• Common Name(s): (+)-Nerolidol
• IUPAC Name: (3S,6S)-3,7,11-Trimethyldodeca-1,6,10-trien-3-ol
• CAS Number: 142-50-7
• FEMA Number: 2772
• Other Identifiers: FL No. 02.078
• Molecular Formula: C15H26O
• Molecular Weight: 222.37 g/mol

(+)-Nerolidol is a sesquiterpene alcohol characterized by its linear structure with three double bonds and a hydroxyl group. The presence of these functional groups contributes to its unique odor profile, which is often described as woody and floral. The structure-odor relationship is significant as the hydroxyl group enhances its solubility in alcohols and oils, making it a versatile ingredient in both flavors and fragrances.

2. Sensory Profile

(+)-Nerolidol is known for its delicate, woody, and floral aroma with subtle fruity undertones. It is often described as having a fresh, green, and slightly citrusy scent. The intensity of its odor is moderate, making it suitable for use as a background note or modifier in complex fragrance compositions. While specific taste thresholds are not well-documented, its role in flavor systems is typically as a subtle enhancer rather than a dominant note.

3. Natural Occurrence & Formation

(+)-Nerolidol is naturally found in the essential oils of several plants, including ginger, jasmine, tea tree, and lemongrass. It is biosynthesized in plants through the mevalonate pathway, which is responsible for the production of terpenoids. Its presence in various essential oils contributes to their designation as "natural flavors" or "natural fragrances," depending on the context of use.

4. Use in Flavors

In flavor applications, (+)-nerolidol is used to impart a subtle woody and floral note, enhancing the complexity of fruit, floral, and herbal flavors. It is commonly used in beverages, confectionery, and baked goods. Typical use levels range from 0.1 to 5 ppm in finished products, with higher concentrations potentially leading to overpowering effects. Its stability is generally good, though it may degrade under high heat or acidic conditions.

5. Use in Fragrances

(+)-Nerolidol is a versatile ingredient in the fragrance industry, used across various fragrance families, including floral, woody, and oriental. It serves as a modifier and impact note, providing depth and complexity to perfumes, soaps, and personal care products. Typical concentration ranges from 0.1% to 1% in formulations, contributing primarily to the middle and base notes due to its moderate volatility.

6. Regulatory Status (Regional Overview)

In the United States, (+)-nerolidol is recognized as GRAS (Generally Recognized As Safe) by FEMA for flavor use. In the European Union, it is listed under Regulation (EC) No 1334/2008 with FL No. 02.078. The UK follows similar regulations post-Brexit. In Asia, regulations vary, with Japan and China having specific guidelines for its use in flavors and fragrances. In Latin America, countries like Brazil and members of MERCOSUR have harmonized regulations for its use.

7. Toxicology, Safety & Exposure Considerations

For oral exposure, (+)-nerolidol has a favorable safety profile with an established ADI (Acceptable Daily Intake) not clearly reported but considered safe at typical use levels. Dermal exposure in fragrances is generally safe, though IFRA guidelines should be consulted to avoid sensitization. Inhalation exposure is minimal due to its moderate volatility, but occupational safety measures should be in place to prevent overexposure in manufacturing settings.

8. Practical Insights for Formulators

(+)-Nerolidol is valued for its ability to enhance the complexity of both flavors and fragrances. It synergizes well with other terpenes and floral compounds, providing a natural and sophisticated aroma profile. Formulators should be cautious of its potential to dominate if used excessively, particularly in delicate compositions. It is often underutilized in formulations where a subtle woody note could enhance the overall profile.

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.
