FlavScents AInsights Entry: Costus Root Oil (CAS: 8023-88-9)

1. Identity & Chemical Information

Costus root oil is a natural complex material derived from the roots of the Saussurea costus plant. It is commonly referred to as costus oil. The CAS number for costus root oil is 8023-88-9. It does not have a specific IUPAC name as it is not a single compound but a mixture of various constituents. The oil is known for its distinctive aroma, which is attributed to its complex composition.

2. Sensory Profile

Costus root oil is characterized by its warm, woody, and earthy aroma with a hint of spicy undertones. It is often described as having a deep, rich scent that can be quite intense. The oil is used as an impact note in both flavors and fragrances, providing a unique character that can enhance the overall sensory experience. The odor threshold is not clearly reported, but its strong diffusion makes it a potent ingredient in formulations.

3. Natural Occurrence & Formation

Costus root oil is primarily obtained from the roots of the Saussurea costus plant, which is native to the Himalayan region. The oil is extracted through steam distillation of the dried roots. It is considered a natural fragrance and flavor material, often used in products labeled as "natural." The formation of its characteristic aroma is due to the complex mixture of sesquiterpenes and other volatile compounds present in the oil.

4. Use in Flavors

Costus root oil is used in various flavor applications, particularly in spice and oriental flavor profiles. It acts as a background realism enhancer and can be used in small quantities to add depth to flavor systems. Typical use levels in finished food or beverage products range from 0.1 to 5 ppm, depending on the desired intensity. The oil is relatively stable under normal processing conditions but may degrade under extreme heat or acidic conditions.

5. Use in Fragrances

In the fragrance industry, costus root oil is valued for its ability to impart a warm, earthy note to perfumes and scented products. It is commonly used in oriental and woody fragrance families. The oil serves as a base note due to its low volatility, providing longevity and depth to the fragrance composition. Typical concentration ranges in perfumes are from 0.1% to 1%, depending on the desired effect.

5a. Key Constituents (Typical)

Costus root oil contains several key constituents, including sesquiterpene lactones such as costunolide and dehydrocostus lactone, which are responsible for its characteristic aroma. The composition of the oil can vary significantly based on the origin, harvest time, and processing methods. These variations can affect the sensory profile and potency of the oil.

6. Regulatory Status (Regional Overview)

In the United States, costus root oil is recognized as GRAS (Generally Recognized As Safe) for flavor use by FEMA. In the European Union, it is subject to regulation under Reg. (EC) No 1334/2008, with specific restrictions on its use due to potential sensitization concerns. 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 have their own regulatory frameworks, often aligning with international standards.

7. Toxicology, Safety & Exposure Considerations

Costus root oil's safety profile varies with its application. For oral exposure in flavors, the oil is considered safe at low levels, with an ADI not clearly established but generally accepted as low. Dermal exposure in fragrances may pose a risk of sensitization, and it is subject to IFRA guidelines to mitigate this risk. Inhalation exposure is generally low risk due to its use in low concentrations. The risk profiles differ between food and fragrance applications, with more stringent controls in place for dermal exposure.

8. Practical Insights for Formulators

Costus root oil is valued for its unique sensory properties, providing warmth and depth to both flavors and fragrances. It synergizes well with other woody and spicy notes but can be overpowering if used excessively. Formulators should be cautious of its potential to cause sensitization and adhere to recommended usage levels. It is often under-used in modern formulations due to its strong character, but when balanced correctly, it can enhance the complexity of a product.

9. Confidence & Data Quality Notes

The data on costus root oil is well-established, particularly regarding its sensory profile and key constituents. However, there are gaps in specific toxicological data, such as precise ADI values. Industry practices often rely on historical usage and expert judgment to guide formulation decisions. Regulatory ambiguities exist, particularly in regions with evolving guidelines.

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.
