Визначення

Sea water is the smell of the sea, a mix of molecules from decay, algae and marine organisms, and it is named as a top note in a men's fragrance introduced in 1988. The smell of the sea is often described as refreshing, fresh, salty or fishy.

Запах

The smell of the seashore can read as slightly sulfury, with a pinch of green and a briny finish. Dimethyl sulfide has a characteristic odor commonly described as cabbage-like. Food scientists describe the flavor of DMS with words such as green, sulfur, clammy, boiled cabbage and creamed corn. Hydrogen sulfide has an aroma often likened to that of rotten eggs. In low concentrations, bromophenols are described as smelling sealike, fishlike and crablike, and in really high concentrations they come off as a harsh chemical smell similar to iodine. Most reports describe dictyopterenes as smelling like dried seaweed.

Calone has a fresh, ozonic marine odor with watermelon, green and oyster-like nuances. It also has an intense "sea-breeze" note with slight floral and fruit overtones.

Докладно

The smell of the sea is produced by a complex mix of chemicals originating from decay, death and bacterial breakdown, combined with a touch of saltiness, algae and marine organisms. No single chemical compound can be named as the essence of the ocean smell.

Dimethyl sulfide (DMS) is a component of the smell of the sea. Others are chemical derivatives of DMS, such as oxides, and algal pheromones such as dictyopterenes. DMS is an organosulfur compound with the formula (CH₃)₂S, and it is the simplest thioether. DMS originates primarily from dimethylsulfoniopropionate (DMSP), a major secondary metabolite in some marine algae. When phytoplankton die, bacteria make DMS from DMSP as they digest them, and the DMS is then released abundantly into the atmosphere. In the marine atmosphere, DMS is oxidized to compounds such as sulfur dioxide, dimethyl sulfoxide, dimethyl sulfone, methanesulfonic acid and sulfuric acid. Bromophenols are a family of volatile compounds with a strong fishy smell, and they also influence the aroma of the sea. Most seafood animals probably do not make bromophenols themselves but acquire them from the marine worms, algae and other bottom-dwelling foods they eat. Hydrogen sulfide, emitted during the bacterial decomposition of dead algae, contributes to the overall scent of the sea. Seaweed eggs release volatile compounds that attract seaweed sperm, and dictyopterenes are one type of these aromatic sex pheromones. Pheromones, substances from the digestive systems of marine organisms and compounds from volcanic activity also shape the scent of the sea.

Marine materials in perfumery

Calone, or methylbenzodioxepinone, is a synthetic marine aroma chemical produced by chemical synthesis. It is not a natural marine extract. It is a white solid, a derivative of 4-methylcatechol. Its structure is similar to brown algae pheromones such as ectocarpene. Calone is used to give the olfactory impression of a fresh seashore through its marine and ozone nuances. Cascalone, the isopropyl homologue of Calone, is a sweet, watery version with a transparent floral signature.

Цікавий факт

Dimethyl sulfide is the most abundant biological sulfur compound emitted to the atmosphere. Seabirds and other ocean animals use the smell of DMS to identify areas rich in phytoplankton, which are also usually packed full of fish. Experiments showed that Antarctic prions detect DMS at biogenic levels and can use it as an orientation cue within a concentration range they might naturally encounter over the ocean.

Отримання й хімія

Спосіб отримання

One published route reacts a catechol with a 1,3-dihaloacetone in the presence of sodium carbonate to give a 1,4-benzodioxane intermediate, which is then converted, again with sodium carbonate, into a 3,4-dihydro-1,5-benzodioxepin-3-one, and the two steps can be run as one without isolating the intermediate. Starting from 4-methylcatechol and 1,3-dichloroacetone, this route gave the 7-methyl compound, which is Calone, in a yield of about 60 percent.

У парфумерії

On the fragrance wheel, marine and aquatic notes sit in the Water subfamily of the Fresh family. The odor strength of marine and aquatic notes is very high, and they can be difficult to balance in a composition.
