FlavScents AInsights Entry: Jasmine Ketolactone (CAS: 70981-24-7)

1. Identity & Chemical Information

Common Name(s): Jasmine Ketolactone
IUPAC Name: Not available
CAS Number: 70981-24-7
FEMA Number: Not available
Other Identifiers: Not available
Molecular Formula and Molecular Weight: Not available
Functional Groups and Structure–Odor Relevance: Jasmine ketolactone is a synthetic compound used in fragrance applications. Its structure is not widely documented in public databases, but it is known for its contribution to jasmine-like aromas.

Citation hooks: FlavScents; PubChem; FEMA

2. Sensory Profile

Jasmine ketolactone is characterized by its floral, jasmine-like aroma, which is both sweet and slightly fruity. It is often used to impart a rich, exotic floral note in fragrance compositions. The intensity of its odor is moderate, making it suitable for use as a background note or a modifier in complex fragrance blends. Specific odor thresholds are not well-documented, but it is typically used in trace amounts to achieve the desired sensory effect.

3. Natural Occurrence & Formation

Jasmine ketolactone does not occur naturally and is synthesized for use in fragrance applications. Its formation involves chemical synthesis processes that are proprietary to manufacturers. As a synthetic compound, it does not qualify for "natural flavor" or "natural fragrance" designations under most regulatory frameworks.

Citation hooks: FlavScents; food chemistry literature; EFSA/JECFA monographs

4. Use in Flavors

Jasmine ketolactone is not commonly used in flavor applications due to its primary role in fragrance. However, when used, it can contribute a floral note to certain flavor profiles, particularly in exotic or floral-themed products. Typical use levels in flavors are not well-documented, but when used, it is likely in very low ppm ranges to avoid overpowering the flavor profile. Stability in flavor systems is generally good, with moderate resistance to heat and pH variations.

5. Use in Fragrances

Jasmine ketolactone is widely used in the fragrance industry, particularly in floral and oriental fragrance families. It serves as a modifier and impact note, providing a jasmine-like aroma that enhances the complexity of a fragrance. Typical concentration ranges in fragrances are from trace amounts up to 1%, depending on the desired intensity. It contributes primarily to the middle notes of a fragrance due to its moderate volatility.

6. Regulatory Status (Regional Overview)

United States: Jasmine ketolactone is not specifically listed by the FDA or FEMA for flavor use. Its use in fragrances is subject to general safety regulations.
European Union: Not explicitly listed under Regulation (EC) No 1334/2008 for flavor use. Fragrance use is regulated under general safety guidelines.
United Kingdom: Follows EU regulations post-Brexit with no specific divergence noted.
Asia: Regulatory status varies; not widely documented for flavor use. Fragrance use is subject to local safety assessments.
Latin America: Similar to the US and EU, with no specific listings for flavor use.

Citation hooks: FEMA; EFSA; national authority publications

7. Toxicology, Safety & Exposure Considerations

Oral Exposure: Not typically used in flavors; therefore, oral exposure data is limited. General safety assessments suggest low toxicity at trace levels.
Dermal Exposure: Used in fragrances; generally considered safe with low irritation potential. IFRA guidelines should be consulted for specific use limits.
Inhalation Exposure: Volatility suggests potential for inhalation exposure, but no significant occupational hazards reported at typical use levels.

Citation hooks: EFSA; FEMA; PubChem; toxicology literature

8. Practical Insights for Formulators

Jasmine ketolactone is valued for its ability to impart a rich, floral aroma reminiscent of jasmine. It synergizes well with other floral and fruity notes, enhancing the overall complexity of a fragrance. Formulators should be cautious of its intensity, as overuse can lead to an overpowering scent. It is often under-utilized in flavor applications due to its primary role in fragrances.

Citation hooks: FlavScents; industry practice

9. Confidence & Data Quality Notes

Data on jasmine ketolactone is primarily industry-sourced, with limited peer-reviewed literature available. While its use in fragrances is well-documented, flavor use data is sparse. Regulatory and safety information is based on general guidelines rather than specific studies.

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.
