oakmoss absolute replacer

Oakmoss absolute replacer is a synthetic fragrance ingredient designed to replicate the complex aroma of natural oakmoss derived from the lichen Evernia prunastri. It appears as a viscous substance with a characteristic mossy, woody odor profile, often accompanied by slight marine or phenolic nuances. Known by multiple trade names such as Fireco Oakmoss, Moss Reco (Charabot), and Oakmoss Givco (Givaudan), this material serves as a reliable alternative in perfume formulations where natural extracts face tightening regulations. The compound is valued for its long-lasting substantivity, providing depth and warmth typical to chypre and woody accords. Chemical information and taxonomy for this replacer can be linked to PubChem. It is sourced through patented blends of synthetic components designed to closely mimic natural oakmoss scent while avoiding allergenic compounds naturally found in oakmoss extracts.

This oakmoss absolute replacer does not occur naturally; rather, it is a synthetic blend created to simulate the olfactory qualities of natural oakmoss, which is a lichen growing on oak trees. It finds primary application as a fragrance agent in perfumery, particularly in compositions requiring mossy and woody notes. These notes evoke leather and earthy accords, making it integral for chypre and woody perfume structures. This replacer aligns with IFRA (Global) standards, particularly valuable since natural oakmoss extracts face restrictions due to allergenic constituents. Its use provides formulators with a compliant, stable alternative that maintains scent intensity and duration without compromising safety guidelines.

Oakmoss absolute replacer exhibits a specific gravity ranging approximately from 0.971 to 0.984 at temperatures between 20 and 25 °C, indicating a dense but manageable liquid for fragrance formulation. Its refractive index values lie between 1.476 and 1.487 at 20 °C, consistent with heavier aromatic substances. The flash point approximates 100 °C (212 °F), underscoring its relatively high thermal stability regarding flammability. This material dissolves readily in alcohol, facilitating its use in alcoholic perfume bases, but remains insoluble in water. These properties collectively support its function as a robust fixative, enhancing fragrance persistence and blending effectively with diverse aromatic compounds.
