Bioactive components from seaweeds

Obtaining bioactive components from Galician seaweeds with applications in cosmetics, health and food sectors

Celtalga Extract, Ltd., a spin-off of the University of Santiago de Compostela. Celtalga manufactures aqueous extracts from brown and green seaweeds collected in the Galician coast. The ultrasound-assisted process applied to obtain extracts uses water as the only solvent, thus being an eco-friendly process. Both ingredients and process are patented by the University of Santiago). Sálvora is a new brand of organic cosmetics that involves innovative ingredients developed by Celtalga.

We wish the society to benefit from the goodness of seaweed extracts properties, through an innovative proposal of facial skin care products. Lab tests of the extracts both in vitro and chemical ones, evidence free radical scavenging, inhibition of the protein glycosylation and several enzymatic activities- such as antielastase and antihyaluronidase- that imply protection against skin damage, be it from aging or oher factors.
