About

Marine, iodine-rich green with ocean character

Scent Profile

Seaweed in perfumery imparts a distinctly marine aroma, marked by salty, iodine-rich facets and subtle green, vegetal undertones. Its scent can evoke ocean breezes, wet rocks, and briny depths, evolving to reveal earthy and slightly metallic nuances. The note often carries a mineralic freshness that lingers as it dries down.

What this is made of

Red seaweed CO2 extract

A natural extract

CAS 68917-51-1

Red seaweed CO2 extract (IFRA NCS). Held at 0.7 because the seaweed note also covers brown algae and fucus, which are different materials. This is the same row that a name match wrongly returns for red-fruits, red-apple and red-currant - here it is genuinely correct.

How the layers join

Origin

Seaweed absolute is typically extracted from brown or green algae species found along coastal regions, especially in France and the British Isles. The extraction process involves solvent extraction of dried seaweed to yield a concentrated, aromatic absolute used in perfumery.

Usage in Perfumery

Perfumers use seaweed primarily as a heart or base note to impart marine realism and complexity to aquatic, fougère, and woody compositions. It blends well with citrus, vetiver, ambergris, and ozonic notes, adding depth and a naturalistic oceanic character to both masculine and unisex fragrances.
