FlavScents AInsights Entry: Spruce Needle Absolute (CAS: 91722-19-9)

1. Identity & Chemical Information

Spruce needle absolute is a natural complex material derived from the needles of spruce trees. It is not a single chemical compound but a mixture of various constituents. The CAS number for spruce needle absolute is 91722-19-9. It does not have a specific FEMA number due to its complex nature. Other identifiers such as FL number, CoE number, or IFRA reference are not typically assigned to complex natural materials like absolutes. As a mixture, it does not have a single molecular formula or molecular weight. The composition of spruce needle absolute can vary significantly depending on the source, harvest time, and processing methods used.

2. Sensory Profile

Spruce needle absolute is characterized by its fresh, green, and woody aroma, reminiscent of a forest environment. It has a moderate to strong intensity with a diffusive quality that can impart a natural, outdoorsy note to formulations. The sensory role of spruce needle absolute is often as an impact note or a background realism enhancer in both flavors and fragrances. Specific odor and taste thresholds are not well-documented, but its distinctive profile makes it a valuable component in creating authentic natural scents and flavors.

3. Natural Occurrence & Formation

Spruce needle absolute is obtained from the needles of spruce trees, primarily Picea abies and Picea mariana. The formation of this absolute involves solvent extraction of the needles, which concentrates the aromatic compounds. Spruce needle absolute is considered a natural fragrance and flavor material, aligning with the "natural flavor" designation due to its direct derivation from plant material without synthetic modification.

4. Use in Flavors

In flavor applications, spruce needle absolute is used to impart a fresh, green, and woody note, often in herbal, coniferous, or forest-themed flavor profiles. It can be used in a variety of products, including beverages, confectionery, and savory items. Typical use levels in finished food or beverage products range from 1 to 10 ppm, with variations depending on the desired intensity and product type. Stability considerations include sensitivity to heat and oxidation, which can alter its aromatic profile.

5. Use in Fragrances

Spruce needle absolute is utilized in fragrance formulations for its fresh, green, and woody scent, fitting well within the fougère, woody, and chypre fragrance families. It serves as a modifier or impact note, providing a naturalistic touch to perfumes, colognes, and personal care products. Typical concentration ranges in fragrances are from 0.1% to 2%, depending on the desired effect and product type. It contributes primarily to the top and middle notes due to its moderate volatility.

5a. Key Constituents (Typical)

Spruce needle absolute typically contains a variety of terpenes and esters, including bornyl acetate, camphene, and α-pinene, which contribute to its characteristic aroma. The composition can vary based on factors such as geographic origin and extraction method. It is important for formulators to verify the specific profile of their spruce needle absolute batch to ensure consistency in product development.

6. Regulatory Status (Regional Overview)

In the United States, spruce needle absolute is generally recognized as safe (GRAS) for flavor use by FEMA. In the European Union, it is subject to the regulations under (EC) No 1334/2008 for flavorings. Post-Brexit, the United Kingdom aligns closely with EU regulations but may have specific divergences. In Asia, regulations vary, with Japan and China having their own specific guidelines for natural flavor materials. In Latin America, countries like Brazil follow MERCOSUR regulations, which generally align with international standards for natural flavorings.

7. Toxicology, Safety & Exposure Considerations

For oral exposure, spruce needle absolute is considered safe within the typical use levels in food and beverages, with no specific ADI or MSDI established. Dermal exposure in fragrances is generally safe, but formulators should consider potential sensitization and irritation, adhering to IFRA guidelines. Inhalation exposure is typically low risk due to its moderate volatility, but occupational exposure should be managed with appropriate ventilation. The risk profiles for food and fragrance applications are similar, with no significant differences noted.

8. Practical Insights for Formulators

Spruce needle absolute is valued for its ability to impart a natural, fresh, and woody character to both flavors and fragrances. It synergizes well with other green and woody notes, enhancing the overall complexity of formulations. Common pitfalls include overuse, which can lead to an overpowering or unbalanced profile. It is often under-used in formulations seeking a subtle, naturalistic touch.

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.
