Laminaria Absolute MD

Latin name :

Laminaria digitata

Botanical profile :

Laminaria refers to a genus of seaweed of the Laminariaceae family. The most cultivated species is Laminaria digitata.

Geographic origin :

Laminaria seaweed is grown on the britanny coast in France.

Chemotypes :

There are several species of laminaria, not only on the coast of Brittany. These include:
Laminaria pallida, found in waters off South Africa and in the Indian Ocean.
Laminaria sinclarii, found in the Pacific Ocean.
Laminaria hyperborea, found in the north of the Atlantic Ocean.

Extraction process :

Laminaria seaweeds are found off the coast of Brittany, in the water or on beaches, where they are collected. The extraction of algae is done directly after their collection. The seaweed is placed on grids in an extraction tank for the first extraction with hexane, at a hot temperature and for several hours. After removal of the plants and evaporation of the extraction solvent, this first extraction gives a laminaria concrete. During the second step, the waxes of the concrete are precipitated by a dilution in alcohol and a glazing step with a temperature gradient from 140 °F to 32°F. After filtration of the precipitated mixture and evaporation of the alcohol, the absolute is collected. The molecular distillation phase (MD) of the extract is carried out in a distillation tank at very low pressure. The objective of this operation is to clear the absolute from any substance giving it its original dark green colour, and to eliminate all the residual waxes of the extract. The result is a colourless and very soluble product in eau de toilette.
