coumarin free liatris odoratissima oil

Coumarin free liatris odoratissima oil is a natural essential oil extracted from the plant species Liatris odoratissima, also known by synonyms such as coumarin free deertongue oil and coumarin free trilisa odoratissima oil. It is recognized for its coumarinic odor signature, providing a distinctive aromatic profile while lacking coumarin compounds. This oil is primarily valued as a fragrance agent and does not contain the typical coumarin constituents found in related oils. The material is identified with CAS number 68916-90-5 and can be referenced in public chemical databases such as PubChem. The oil is obtained through steam distillation of the plant's aerial parts, yielding a product utilized mainly in perfumery and related scent applications.

Coumarin free liatris odoratissima oil originates biologically from the herbaceous plant Liatris odoratissima, native to certain North American regions where it grows as a wildflower. The oil is extracted from this natural source and serves primarily as a fragrance agent in scented product formulations. Due to its composition lacking coumarin, it finds use in fragrance applications requiring coumarin-free profiles, allowing for alternative olfactory effects. Its usage is regulated under standards such as the IFRA Code of Practice (Global), which provides specific guidance on safe fragrance material levels. While it is not intended for flavor use, the oil’s unique coumarinic aroma makes it valuable in perfumery and cosmetic product scenting where coumarin restrictions apply.

The physico-chemical properties of coumarin free liatris odoratissima oil are influenced by its natural origin and chemical composition devoid of coumarin compounds. It exhibits a characteristic coumarinic odor at 100% concentration, imparting a sweet, herbaceous aroma typical of deertongue oils. The absence of coumarin affects volatility and scent longevity, distinguishing it from related oils containing coumarin. These properties enable formulators to utilize the oil in fragrance applications without the phototoxicity or sensitization concerns associated with coumarin. The oil's chemical stability and organoleptic profile support its incorporation in diverse aromatic blends. While specific physical constants such as boiling point or refractive index are not detailed here, the oil behaves as an essential oil fraction suitable for steam distillation extraction methods.
