picea glauca leaf absolute

Picea glauca leaf absolute is a natural aromatic extract obtained from the needles of the white spruce, Picea glauca. This absolute typically appears as a viscous, greenish liquid and is valued for its distinctive olfactory profile characterized by green, resinous, balsamic, fruity, and coumarinic notes. It is known under various synonyms including abies canadensis leaf absolute and white spruce needle absolute, reflecting its botanical origin. The extraction process yields a concentrated fragrance material used primarily in perfumery and flavoring industries. For detailed chemical information, see its PubChem profile. The raw material is sourced directly from Picea glauca foliage, predominantly harvested in regions where the species naturally grows.

Picea glauca leaf absolute is derived biologically from the needles of the white spruce tree, a species native to North America. This botanical extract is primarily employed as a fragrance agent in perfumery and cosmetic formulations due to its characteristic green, resinous aroma. It is not recommended for flavor use. Under IFRA (Global) standards, special attention is given to the peroxide levels in such pinaceous essential oils and absolutes, requiring that peroxide values remain below 10 millimoles per liter to maintain quality and safety. The absolute is valued for imparting fresh green and balsamic notes in diverse fragrance applications.

The physicochemical profile of picea glauca leaf absolute affects its behavior in formulation. It is soluble in alcohol solvents but insoluble in water, which influences its incorporation into hydroalcoholic perfume blends rather than aqueous systems. Its green, resinous, and balsamic odor is stable under typical ambient temperatures encountered in product formulation. The absolute is generally viscous, exhibiting a consistency that requires consideration during handling and blending. To maintain fragrance quality, the peroxide content must be controlled through antioxidant addition, preventing degradation and ensuring consistent olfactory properties.

IFRA fragrance material specification:
	Essential oils (e.g. turpentine oil) and isolates (e.g. delta-3-carene) derived from the Pinacea family, including Pinus and Abies genera, should only be used when the level of peroxides is kept to the lowest practicable level, for instance by adding antioxidants at the time of production. Such products should have a peroxide value of less than 10 millimoles peroxide per liter, determined according to the FMA method, which can be downloaded from the IFRA website (see Analytical Methods).
Recommendation for picea glauca leaf absolute flavor usage levels up to:
	not for flavor use.
