FlavScents AInsights Entry: Alcohols C7-9-iso- C8-rich (CAS: 68526-83-0)

1. Identity & Chemical Information

Common Name(s): Alcohols C7-9-iso- C8-rich
CAS Number: 68526-83-0
FEMA Number: Not applicable
Other Identifiers: Not available
Molecular Formula and Molecular Weight: As this is a mixture, specific molecular formula and weight are not applicable.
Functional Groups and Structure–Odor Relevance: This material is a mixture of iso-alcohols, primarily C8, which are known for their role in providing a balance of volatility and substantivity in fragrance applications.

Citation hooks: FlavScents; PubChem; FEMA

2. Sensory Profile

Odor and Flavor Descriptors: Alcohols C7-9-iso- C8-rich are typically described as having a mild, fatty, and slightly floral odor. The intensity is moderate, providing a subtle background note rather than a dominant scent.
Taste and/or Odor Thresholds: Specific thresholds are not clearly reported, but the material is generally used in low concentrations due to its moderate intensity.
Typical Sensory Role: This material often serves as a background realism enhancer in both flavors and fragrances, contributing to the overall complexity without overpowering other components.

Citation hooks: FlavScents; peer-reviewed sensory literature

3. Natural Occurrence & Formation

Known Natural Sources: These alcohols are not typically found in nature as a distinct mixture but can be components of essential oils and other natural extracts.
Formation Pathways: They can be synthesized through the hydroformylation of olefins followed by hydrogenation, a common industrial process for producing fatty alcohols.
Relevance to “Natural Flavor” or “Natural Fragrance” Designation: While the individual alcohols may occur naturally, the mixture itself is typically considered synthetic unless derived from natural sources.

4. Use in Flavors

Flavor Categories and Applications: Alcohols C7-9-iso- C8-rich are used in a variety of flavor applications, including dairy, fruit, and confectionery, where they enhance mouthfeel and provide subtle background notes.
Functional Role in Flavor Systems: They act as modifiers, enhancing the richness and depth of flavors.
Typical Use Levels: Documented use levels range from 1 to 10 ppm in finished products, with typical industry use around 5 ppm.
Stability Considerations: These alcohols are generally stable under typical food processing conditions, including moderate heat and pH variations.

5. Use in Fragrances

Fragrance Families and Product Types: Commonly used in floral, woody, and fresh fragrance compositions, suitable for personal care products and household items.
Functional Role: They serve as modifiers and impact notes, providing a smooth transition between top and middle notes.
Typical Concentration Ranges: Used at concentrations ranging from 0.1% to 1% in fragrance formulations.
Volatility and Top/Middle/Base Contribution: These alcohols contribute primarily to the middle notes due to their moderate volatility.

6. Regulatory Status (Regional Overview)

United States (FDA / FEMA GRAS): Not explicitly listed as GRAS; usage is based on industry practice and safety assessments.
European Union (Reg. (EC) No 1334/2008): Not specifically listed; usage is subject to general safety evaluations.
United Kingdom: Follows EU regulations post-Brexit with no significant divergence reported.
Asia (Japan, China, ASEAN): Usage is generally aligned with international safety standards, but specific approvals may vary.
Latin America (e.g., Brazil, MERCOSUR): Usage is typically harmonized with international guidelines, though specific national regulations should be consulted.

Citation hooks: FEMA; EFSA; national authority publications

7. Toxicology, Safety & Exposure Considerations

Oral Exposure: No specific ADI or MSDI values are reported; usage is based on general safety data for similar alcohols.
Dermal Exposure: Generally considered safe for use in personal care products at typical concentrations; no significant irritation or sensitization reported.
Inhalation Exposure: Volatility is moderate, with no specific occupational exposure limits; general ventilation is recommended during handling.
Risk Profiles: Similar safety profiles for both food and fragrance applications, with no significant differences noted.

8. Practical Insights for Formulators

Why This Material is Valuable: Provides a balance of volatility and substantivity, enhancing the complexity of both flavors and fragrances.
Typical Synergies: Works well with esters and other alcohols to create smooth, rounded profiles.
Common Formulation Pitfalls: Overuse can lead to a fatty or waxy note; careful balancing is required.
Situations Where It is Frequently Over- or Under-used: Often under-utilized in formulations seeking subtlety and depth.

9. Confidence & Data Quality Notes

Well-Established Data: General sensory and functional roles are well-documented.
Industry-Typical but Undocumented Practices: Usage levels and synergies are often based on industry experience rather than formal studies.
Known Data Gaps or Regulatory Ambiguities: Specific regulatory listings and detailed toxicological data are limited.

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.
