FlavScents AInsights Entry: Rosa Canina Seed Extract (CAS: 84696-47-9)

1. Identity & Chemical Information

Rosa canina seed extract, commonly known as rosehip seed extract, is derived from the seeds of the Rosa canina plant. This extract is a complex natural material, not a single chemical compound, and thus does not have a specific IUPAC name or molecular formula. The CAS number for this extract is 84696-47-9. It is important to note that the composition of rosa canina seed extract can vary significantly depending on the geographical origin, harvest time, and processing methods used.

2. Sensory Profile

Rosa canina seed extract is primarily valued for its subtle, earthy aroma with a hint of floral notes. It is not typically used for its flavor but rather for its fragrance properties. The odor intensity is mild, making it suitable for use as a background note or modifier in fragrance compositions. The extract does not have a well-documented taste or odor threshold, and its sensory role is often to provide a natural, earthy base that complements more prominent floral or fruity notes.

3. Natural Occurrence & Formation

Rosa canina, commonly known as the dog rose, is a wild rose species native to Europe, northwest Africa, and western Asia. The seeds of this plant are harvested and processed to produce the extract. The formation of the extract involves cold pressing or solvent extraction methods, which help preserve the natural constituents. Rosa canina seed extract is often labeled as a "natural fragrance" due to its plant-based origin and minimal processing.

4. Use in Flavors

While rosa canina seed extract is not commonly used in flavor applications due to its mild sensory profile, it can occasionally be found in niche products where a subtle, earthy note is desired. Its use levels in flavors are typically very low, often in the range of 1-10 ppm, primarily as an industry-typical estimate. The extract is stable under normal flavor formulation conditions, but care should be taken to avoid excessive heat or oxidation, which can degrade its quality.

5. Use in Fragrances

In the fragrance industry, rosa canina seed extract is used across various fragrance families, including floral, woody, and green compositions. It serves as a modifier or background note, providing a natural, earthy base that enhances the complexity of the fragrance. Typical concentration ranges in fragrance formulations are from 0.1% to 1%, depending on the desired intensity and product type. The extract contributes primarily to the middle notes of a fragrance due to its moderate volatility.

5a. Key Constituents (Typical)

Rosa canina seed extract contains several key constituents, including fatty acids such as linoleic acid, alpha-linolenic acid, and oleic acid. It may also contain trace amounts of volatile compounds that contribute to its aroma profile. The composition can vary significantly based on factors such as origin and processing methods.

6. Regulatory Status (Regional Overview)

In the United States, rosa canina seed extract is generally recognized as safe (GRAS) for use in fragrances but is not commonly used in flavors. In the European Union, it is regulated under Regulation (EC) No 1334/2008 for flavorings, although its use is more prevalent in cosmetics and personal care products. The United Kingdom follows similar regulations post-Brexit. In Asia, including Japan and China, and in Latin America, such as Brazil, the extract is primarily used in cosmetics, with specific regulations varying by country.

7. Toxicology, Safety & Exposure Considerations

Rosa canina seed extract is considered safe for use in fragrances, with low potential for dermal irritation or sensitization. It is not typically used in food products, so oral exposure data is limited. Inhalation exposure is generally considered safe due to its low volatility and mild aroma. The extract's safety profile is consistent across both food and fragrance applications, with no significant differences in risk.

8. Practical Insights for Formulators

Rosa canina seed extract is valued for its ability to provide a natural, earthy base in fragrance formulations. It synergizes well with floral and fruity notes, enhancing the overall complexity of the fragrance. Formulators should be cautious of overuse, as its subtle aroma can be easily overshadowed by more dominant notes. It is often under-used in formulations where a natural, grounding element is desired.

9. Confidence & Data Quality Notes

The data on rosa canina seed extract is well-established in terms of its sensory profile and use in fragrances. However, there are gaps in documented flavor applications and specific regulatory approvals outside of cosmetics. Industry practices are often based on traditional use and anecdotal evidence rather than comprehensive scientific 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.
