Laminaria digitata (Kombu)

Laminaria digitata, also known as “oarweed”, is a macro-algae found in the North Atlantic, Baltic and North Sea, which can form extensive seaweed forests.

The best known and economically most relevant use of Laminaria digitata is the production of alginate from the alginic acid it contains, which is used as a thickening agent for the food industry.
But it can also be consumed as a seaweed vegetable.

In the past, Laminaria digitata was valued and used as a natural fertiliser and iodine source.

In addition to its use as a food and fertilizer, oarweed also has much to offer the cosmetics industry.
Due to its many minerals and trace elements, Laminaria digitata has a revitalising and mineralising effect on the skin. Added to this are moisturising and antioxidant properties that protect the skin from external influences.

The liquid is usually used in the production of cosmetics and aquaristics.

This product is available in the following forms of liquid extracts:

• Water extract
• Debacterialized water extract
• Glycerin extract 
• Water-glycerin extract
• Oil extract

The product is also available as powder.

Typical applications in the cosmetics industry:

Laminaria digitata has good moisturizing and remineralizing properties, which are based on the broad nutrient profile. Among them, for example, alginates, mannitol and amino acids.

This nutrient profile helps to support the skin in its natural protection. Laminaria digitata acts as an antioxidant and reduces the effects of oxidative stress on the skin.

In addition, Laminaria digitata can be used in anti-aging cosmetics as it tightens the skin and reduces wrinkles. The macroalga revitalizes the skin by covering and replenishing the natural needs of minerals, vitamins, proteins and carbohydrates. This has a positive effect on the appearance of the skin and has a supporting effect in keeping the skin young for as long as possible.
