FlavScents AInsights Entry for Picea Glauca Branch/Leaf Oil (CAS: 91722-18-8)

1. Identity & Chemical Information

Picea glauca branch/leaf oil, commonly known as white spruce oil, is a natural complex material derived from the branches and leaves of the Picea glauca tree. It is not a single chemical compound but a mixture of various constituents. The CAS number for this essential oil is 91722-18-8. While there is no specific FEMA number assigned to this oil, it is recognized in various fragrance and flavor applications. Other identifiers such as FL number or CoE number are not typically assigned to complex natural materials like essential oils. The composition of this oil can vary significantly depending on the geographical origin, harvest time, and processing methods used.

2. Sensory Profile

Picea glauca branch/leaf oil is characterized by its fresh, woody, and resinous aroma, reminiscent of a forest environment. The oil has a moderate to strong intensity and is often used to impart a natural, green, and coniferous note to both flavors and fragrances. It serves as an impact note in formulations, providing a crisp and invigorating scent profile. The taste and odor thresholds for this oil are not well-documented, but its sensory role is primarily as a background realism enhancer in flavor systems and a modifier in fragrance compositions.

3. Natural Occurrence & Formation

Picea glauca, or white spruce, is native to North America, particularly found in Canada and the northern United States. The essential oil is obtained through steam distillation of the tree's branches and leaves. This oil is considered a natural fragrance and flavor material, aligning with the "natural" designation due to its direct extraction from plant material without synthetic modification. The formation of its characteristic aroma compounds involves the enzymatic degradation of terpenes and other volatile organic compounds present in the plant tissue.

4. Use in Flavors

In flavor applications, Picea glauca branch/leaf oil is used to impart a fresh, pine-like note to various products, including beverages, confectionery, and savory items. It functions as a background realism enhancer and can be used in combination with other natural flavors to create complex profiles. Typical use levels in finished food or beverage products range from 1 to 10 ppm, with higher concentrations potentially leading to overpowering notes. The oil is relatively stable under normal processing conditions but may degrade under prolonged exposure to heat and light.

5. Use in Fragrances

Picea glauca branch/leaf oil is utilized in fragrance formulations across various product types, including personal care products, household cleaners, and air fresheners. It is commonly found in the woody and fresh fragrance families, serving as a modifier or impact note. The oil contributes primarily to the top and middle notes of a fragrance composition due to its moderate volatility. Typical concentration ranges in fragrance products are from 0.1% to 2%, depending on the desired intensity and product type.

5a. Key Constituents (Typical)

The major constituents of Picea glauca branch/leaf oil include α-pinene, β-pinene, camphene, and limonene, which contribute to its characteristic aroma. The composition can vary based on factors such as the geographical origin of the plant material and the distillation process used. It is important for formulators to verify the specific composition of the oil they are using to ensure consistency in their products.

6. Regulatory Status (Regional Overview)

In the United States, Picea glauca branch/leaf oil is generally recognized as safe (GRAS) for use in flavors by FEMA. In the European Union, it is subject to the regulations outlined in Reg. (EC) No 1334/2008, although it does not have a specific FL number. The regulatory status in the United Kingdom remains aligned with the EU post-Brexit. In Asia, the oil is used in accordance with local regulations in countries like Japan and China, where it is often included in traditional formulations. In Latin America, countries such as Brazil and members of MERCOSUR have their own guidelines for the use of essential oils in flavors and fragrances.

7. Toxicology, Safety & Exposure Considerations

For oral exposure, Picea glauca branch/leaf oil is considered safe at typical flavor use levels, with no specific ADI or MSDI established. Dermal exposure in fragrance applications should be approached with caution due to potential sensitization risks; IFRA provides guidelines on safe use concentrations. Inhalation exposure is generally low risk in consumer products, but occupational exposure should be managed to prevent respiratory irritation. The risk profiles for food and fragrance applications are similar, with the primary concern being dermal sensitization in fragrance use.

8. Practical Insights for Formulators

Picea glauca branch/leaf oil is valued for its ability to impart a natural, fresh, and woody aroma to both flavors and fragrances. It synergizes well with other coniferous and citrus notes, enhancing the overall complexity of a formulation. Common pitfalls include overuse, which can lead to an overpowering scent or flavor, and variability in composition, which requires careful sourcing and quality control. It is frequently under-used in formulations seeking a natural forest-like aroma.

9. Confidence & Data Quality Notes

The data on Picea glauca branch/leaf oil is well-established in terms of its sensory profile and typical uses. However, there are gaps in specific toxicological data and regulatory approvals in certain regions. Industry practices often rely on historical use and expert judgment, particularly in fragrance applications.

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.
