FlavScents AInsights Entry: Seaweed Oleoresin (CAS: 68917-51-1)

1. Identity & Chemical Information

Seaweed oleoresin is a natural complex material derived from various species of seaweed. It is not a single chemical compound but a mixture of various constituents extracted from seaweed. The CAS number for seaweed oleoresin is 68917-51-1. It does not have a specific FEMA number or IUPAC name due to its complex nature. Other identifiers such as FL number, CoE number, or IFRA reference are not typically assigned to such complex materials. The composition of seaweed oleoresin can vary significantly depending on the species of seaweed used, the geographical origin, and the extraction process employed.

2. Sensory Profile

Seaweed oleoresin is known for its distinctive marine aroma, which can be described as oceanic, salty, and slightly green. The intensity of the odor can vary, but it generally provides a strong impact note that is reminiscent of the sea. It is often used to impart a sense of freshness and natural marine character to both flavors and fragrances. The taste threshold for seaweed oleoresin is not well-documented, but its sensory role is typically as an impact note or a background realism enhancer in formulations.

3. Natural Occurrence & Formation

Seaweed oleoresin is naturally sourced from various species of seaweed, which are abundant in marine environments worldwide. The oleoresin is typically obtained through solvent extraction processes that concentrate the aromatic and flavor compounds present in the seaweed. Seaweed is a common component in "natural flavor" and "natural fragrance" designations due to its natural origin and the minimal processing involved in oleoresin production.

4. Use in Flavors

In flavor applications, seaweed oleoresin is used to impart a marine or oceanic note to a variety of products, including seafood-flavored snacks, soups, and sauces. It serves as a functional ingredient that enhances the authenticity and complexity of marine flavors. Typical use levels in finished food products can range from 10 to 100 ppm, depending on the desired intensity and the specific application. Seaweed oleoresin is generally stable under typical food processing conditions, but it may be sensitive to prolonged exposure to high heat and oxidation.

5. Use in Fragrances

In the fragrance industry, seaweed oleoresin is valued for its ability to add a fresh, marine character to perfumes and personal care products. It is commonly used in aquatic and oceanic fragrance families, where it acts as a modifier or impact note. The concentration of seaweed oleoresin in fragrance formulations can vary widely, but it is typically used at low levels to avoid overpowering other notes. Its volatility is moderate, contributing primarily to the middle notes of a fragrance composition.

5a. Key Constituents (Typical)

Seaweed oleoresin typically contains a variety of constituents, including polysaccharides, proteins, and lipids, as well as minor components like iodine and other minerals. The exact composition can vary based on the species of seaweed and the extraction method used. It is important to note that the composition may change with different harvests and processing techniques.

6. Regulatory Status (Regional Overview)

In the United States, seaweed oleoresin is generally recognized as safe (GRAS) for use in flavors by FEMA. In the European Union, it is regulated under Regulation (EC) No 1334/2008, but specific FL number status may not be assigned due to its complex nature. The United Kingdom follows similar regulations post-Brexit. In Asia, including Japan and China, seaweed oleoresin is used in traditional foods and is generally accepted, though specific regulatory details may vary. In Latin America, countries like Brazil and those in MERCOSUR may have their own regulations, but seaweed oleoresin is typically accepted in flavor applications.

7. Toxicology, Safety & Exposure Considerations

For oral exposure, seaweed oleoresin is considered safe within the typical use levels in food, with no specific ADI or MSDI established. Dermal exposure in fragrance applications is generally safe, but formulators should be aware of potential sensitization in sensitive individuals. Inhalation exposure is not typically a concern due to the low volatility of the oleoresin. Overall, the risk profiles for food and fragrance applications are similar, with no significant safety concerns reported.

8. Practical Insights for Formulators

Seaweed oleoresin is valued for its ability to impart a natural marine character to both flavors and fragrances. It synergizes well with other oceanic and green notes, enhancing the overall freshness and complexity of formulations. Formulators should be cautious of overuse, as the strong marine aroma can dominate other components. It is often under-utilized in non-marine applications where a subtle hint of oceanic freshness could add depth.

9. Confidence & Data Quality Notes

The data on seaweed oleoresin is well-established in terms of its sensory profile and typical applications. However, specific regulatory details and toxicological data may be less documented, requiring formulators to rely on industry-typical practices and informed estimates. Known data gaps include precise compositional analysis and detailed safety assessments for all potential exposure routes.

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.
