MARINE INGREDIENTS
Fucoidan: Where science meets sustainability

The demand for quality marine ingredients is being fuelled from three directions. Skincare formulators are increasingly seeking new ingredients that are natural, efficacious and sustainable. Investment in robust scientific research and in advanced green chemistry technologies have now placed novel seaweed extracts at the forefront of science and sustainability. A look through history reveals that seaweeds
have been prized for their dietary and therapeutic properties for centuries.1
However, it
has only been in more recent times that some of their unique compounds have been identified and studied for their bioactive properties.
Introducing fucoidan Fucoidans, pronounced ‘few-coy-dens’, are one of these compounds. Derived from brown seaweeds, these bioactive polysaccharides serve to protect the seaweed plant against a range of external stresses. Recent advances in science indicate that many of the same protective benefits that fucoidans offer to the seaweed plant may also be harnessed to address a wide range of human health indications.
The benefits of fucoidan for human health
extend to dermal conditions where soothing and protecting properties are paramount. It is for these reasons that fucoidan extracts are now

making waves across the personal care sector. Market awareness of high purity, certified
organic fucoidans is growing at a rapid rate. Of particular interest to brand innovators are those fucoidan extracts that also have global regulatory acceptance. These ingredients present a very potent
value proposition and are increasingly appearing in market-leading skincare formulations. They are top of mind for companies looking to develop personal care products with a novel flagship ingredient that is effective and offers a clear point of differentiation. High purity fucoidans with global regulatory
acceptance also meet rising consumer expectations around sustainability. Supported by an extensive dossier of
scientific evidence, high purity fucoidan extracts have been developed to support the youthful appearance of skin by protecting its building blocks and enhancing dermal condition.2 They have been shown to have potent
antioxidant capabilities and have been clinically shown to improve skin brightness, reduce age spots and reduce wrinkles. The same ingredients also offer a range of sought-after healthy ageing properties, both protecting the skin from damage and soothing the skin following exposure to stressful environmental conditions.2
In vitro research has also demonstrated
the potential for fucoidan extracts to support a healthy epidermal barrier and assist in the balancing of skin microbiome.3
In a recent
study, high purity fucoidans were shown to significantly inhibit the adhesion of the bacterium Staphylococcus aureus, a known aggravator of the widespread condition atopic dermatitis, or eczema. The adhesion of the bacterium
Cutibacterium acnes, which is believed to play an important role in the widespread skin condition acne, was also significantly reduced. Importantly, the fucoidan did not affect the adhesion of Staphylococcus epidermidis – a common bacterium found on healthy skin. Fucoidans hold promising therapeutic
potential for use in topical treatments for inflammatory skin conditions and as such are increasingly attracting the attention of dermatologists and allied clinicians.
Award-winning green chemistry Manufacturers of fucoidan extracts have traditionally utilised solvents to precipitate the fucoidan polymer from crude seaweed extracts.4
This traditional methodology may
lead to contaminants being present in the final extract. Fucoidans manufactured in this way can suffer from many shortfalls; their quality can be inconsistent, their chemical integrity may be
