What does seaweed smell like in perfume?
Seaweed smells salty, mineral and marine, like a breeze off the rocks at low tide. It gives a perfume a genuine sense of the sea, without the synthetic “ocean” notes common in modern fragrances.

What Is Seaweed?
Seaweed absolute is extracted from bladderwrack, Fucus vesiculosus, a brown seaweed gathered on Atlantic coasts. It is one of the few natural materials that can bring a true marine note to perfume.

How Perfumers Use Seaweed
Perfumers use seaweed in small amounts to add realism to aquatic compositions, pairing it with citrus, herbs and woods. It gives depth to fresh scents and a natural, salty skin effect.
Growing and harvesting seaweed
Bladderwrack grows on rocky shores between the tides along the coasts of Brittany, Ireland and Scotland. It is gathered by hand at low tide and cut above the holdfast that anchors it to the rock, so that it can grow back. For perfume it is extracted into an absolute, which gives only a tiny yield.
The molecules behind seaweed’s scent
The “sea air” smell of the coast comes largely from dimethyl sulfide, released as seaweed breaks down. Brown seaweeds also give off dictyopterenes, which carry the distinctive smell of a rock pool. Seaweed absolute holds traces of these with darker, iodine-like and green notes.
Natural or synthetic seaweed?
Most marine notes in mainstream perfumes come from Calone, a synthetic molecule discovered in the 1960s that smells of watermelon and sea breeze. Real seaweed smells quite different: saltier, greener and darker, closer to a rock pool than an ocean breeze.
Seaweed in history and tradition
Bladderwrack and other wracks have been gathered from rocky shores for centuries. Coastal farmers in Scotland, Ireland and Brittany spread them on their fields, and in the 18th century burned seaweed, known as kelp, was a major source of soda for glass and soap making. The chemical element iodine was first discovered in seaweed ash, by the French chemist Bernard Courtois in 1811. In perfumery, natural seaweed absolute brings the smell of a rock pool into marine and fougère blends.
How to smell seaweed yourself
Walk along a rocky beach at low tide and smell the wrack drying on the stones. That damp, salty, slightly sulphurous smell is the real thing, and you will notice it is nothing like the sweet, watery “ocean” note of many modern fragrances.
