Pelvetia canaliculata

Other names: Channeled wrack

Pelvetia canaliculata, also known as Channeled wrack, is a species of seaweed found on the rocky shores of the North Atlantic. This brown seaweed is special because of its characteristic shape, which resembles small channels or grooves. It grows in clumps and an adult measures between 10 and 25 cm in diameter. It is a very resilient species that is able to survive even when exposed out of the water at low tide.

Channeled wrack is used in numerous industries. As a source of iodinated compounds, it is used in health care and cosmetics. It can be found in skin care creams where it acts as a protective, highly moisturizing and soothing factor. Due to its phycosterol, vitamin and mineral content, it also has anti-ageing and anti-inflammatory properties. In the food industry, this algae is used as a source of iodine, vitamins and other important minerals. Some scientific studies also suggest that Pelvetia canaliculata could be used for biofuel production, as it contains substances with potential energy uses.
