deertongue absolute

Deertongue absolute is a fragrant extract from Liatris odoratissima with sweet, herbal, tobacco-like, and vanilla nuances mainly used in perfumery.

General Material Description

Deertongue absolute is a natural aromatic extract derived from the plant Liatris odoratissima (Walt.) Willd., commonly known as deertongue. Classified as an absolute, it is a dense, viscous material obtained through solvent extraction of the plant’s flowering parts. This absolute is recognized for its distinctive, sweet, tonka and coumarin-like aroma combined with herbal and tobacco nuances. Among its synonyms are liatris odoratissima absolute and trilisa odoratissima absolute. The extract contributes complex fragrance qualities reminiscent of vanilla and fresh hay, making it valuable in fine fragrance formulations. Its chemical profile and sensory attributes are documented under identifiers including CAS numbers 68606-82-6 and 8024-14-4. For detailed chemical and structural information, controlled-vocabulary references such as PubChem provide comprehensive data. This substance is obtained primarily from natural botanical sources native to North America.

Occurrence, Applicability & Potential Uses

Deertongue absolute originates from the botanical species Liatris odoratissima, a plant native to regions in North America. Its aromatic extract is widely used in the fragrance industry due to its rich coumarinic and tobacco-like nuances. It serves as a natural substitute for beeswax absolute and contributes to fragrance families such as oriental, amber, chypre, and tobacco accords. Additionally, it imparts notes reminiscent of coconut, moss, and freshly mown hay, thereby broadening its applicability in perfumery. Usage guidelines follow standards established by IFRA (Global), which regulate concentration levels in fragrance compositions to ensure consumer safety. Typical recommended maximum use levels in fragrance concentrates reach up to 2% for this absolute. Deertongue absolute is not approved for use in flavor applications due to regulatory restrictions and safety considerations.

Physico-Chemical Properties Summary

Deertongue absolute exhibits solubility characteristics favorable to alcoholic solvents, facilitating its integration in various fragrance formulations. While insoluble in water, estimated solubility in water at 25 °C is approximately 5126 mg/L, indicating partial miscibility under certain conditions. This behavior influences its volatility and diffusion when incorporated into perfume bases. The absolute’s dense, viscous nature and pronounced coumarinic compounds contribute to its stability and scent longevity. The presence of significant coumarin content requires careful handling to avoid sensitization reactions. Its molecular composition aligns with aromatic compounds derived primarily through solvent extraction methods from botanical materials, conferring a complex chemical profile suitable for perfumery but necessitating adherence to international safety standards such as those outlined by IFRA and RIFM.

FAQ

What is deertongue absolute and where does it come from?
Deertongue absolute is a fragrant extract obtained by solvent extraction from the flowering parts of Liatris odoratissima, commonly called deertongue. This botanical source is native to North America. The absolute is known for its sweet, coumarinic scent combined with herbal and tobacco-like notes. It is classified as an absolute, a concentrated aromatic product derived from natural plant material using organic solvents. Its key identifiers include CAS numbers 68606-82-6 and 8024-14-4.
How is deertongue absolute used and what are its typical fragrance applications?
Deertongue absolute is primarily utilized as a fragrance ingredient in perfumery, where its sweet, vanilla-like, tobacco, and herbal scent profiles enhance oriental, amber, chypre, and tobacco accords. It can act as a natural substitute for beeswax absolute due to its similar olfactory qualities. Its solubility in alcohol facilitates formulation with other aromatic compounds. Recommended use levels in fragrance concentrates typically do not exceed 2% in accordance with IFRA (Global) guidelines, ensuring safe incorporation while maintaining its potent aromatic impact.
What regulatory standards apply to deertongue absolute and how is its safety assessed?
Deertongue absolute is regulated under fragrance material safety guidelines including IFRA (Global) standards, which specify maximum usage limits in fragrance formulations to prevent sensitization. Safety assessments by RIFM indicate the presence of compounds such as coumarin and dihydrocoumarin, restricted at specific concentrations due to allergenic potential. Toxicity studies report oral and dermal LD50 values above 5000 mg/kg in animal models, reflecting low acute toxicity. This absolute is not recommended for flavor use. Further safety and regulatory details are available through EPA and national substance registries.
