green algae absolute

Green algae absolute is a natural fragrance and flavor material obtained primarily from the bladderwrack seaweed species Fucus vesiculosus. This absolute typically presents as a viscous oil with a pronounced marine odor characterized by fresh, green, sandy, and oily nuances reminiscent of paint and oakmoss at pure concentration. It belongs to the category of absolutes, which are concentrated aromatic extracts often used in perfumery and flavoring. Synonyms for green algae absolute include algae absolute brown, fucus absolute, seaweed absolute, and oils, Fucus vesiculosus, linking this material chemically and commercially to similar seaweed extracts. The compound is well documented in chemical databases such as PubChem, facilitating technical reference and regulatory assessment. It is derived from seaweed biomass through solvent extraction, preserving its complex aromatic constituents associated with marine environments.

Green algae absolute originates biologically from bladderwrack (Fucus vesiculosus), a brown seaweed commonly found along temperate coastal waters. This material is valued in the flavor and fragrance sector for its unique marine and green odor profile, which harmonizes well with floral, amber, moss, and chypre accord notes. Its uses extend to enhancing marine, sea breeze, and oceanic character notes in perfumes, as well as in flavor compositions providing savory green and algae-like nuances. The IFRA (Global) standard recommends usage up to 0.8% in fragrance concentrates to maintain safety and product performance. The absolute also supports diffusion qualities in perfumes and is suitable for fantasy blends requiring an authentic aquatic green note.

Green algae absolute is characterized by a flash point of approximately 100°C (212°F), indicating moderate volatility and safety in formulation under typical handling temperatures. The material’s oily, viscous nature and strong substantivity, with odor lasting around 400 hours at full strength, influence its slow evaporation rate, making it useful for lasting fragrance impressions. Its physicochemical profile favors applications where sustained marine and green notes are desired, and it blends well with other natural and synthetic fragrance inputs. These traits provide formulators with an ingredient that balances fresh aquatic characteristics with durability and olfactory complexity.
