compromised and – most importantly – their bioactivity may be affected. Australian biotechnology company Marinova
has developed revolutionary extraction technology to overcome these problems. Marinova’s exclusive proprietary process does not use organic solvents and produces fucoidan extracts that remain unadulterated in chemical structure and free from solvent residues.5 The mild, aqueous process also ensures the
resulting extracts comply with the most rigorous quality standards and regulatory requirements. This award-winning extraction process produces efficacious, high purity fucoidan extracts that are also certified organic. It is a technological advance, or ‘eco-innovation’, that was recently celebrated in the prestigious national Australian Business Awards.6
Sustainable sourcing High purity, certified organic fucoidans that hold global regulatory acceptance have emerged as exemplars for sustainability. Manufacturers of the highest quality fucoidans have made genuine commitments to ethical and sustainable seaweed harvesting practices. Their management of wild
seaweeds, a rapidly renewable marine resource, resonates strongly with the growing ‘blue beauty’ movement and its commitment to ocean care. Global leaders in fucoidan science
source wild seaweeds from the cleanest ocean waters, well away from sources of industrial, human or agricultural contamination. Industry best practice also sees the seaweeds harvested in accordance with world’s best practice, and on an environmentally sustainable basis. Genuine sustainability practices are evident
right throughout the fucoidan supply chain, with the world’s top producers now aligning their practices with the United Nation’s Sustainable Development Goals. These practices include the utilisation of renewable energy, through to the operation of state-of-the-art extraction facilities that capture and re-use all by- products to achieve a zero-waste outcome. Marinova, for example, captures all liquid and solid by-products from its fucoidan extraction process and converts these into nutrient-rich organic additives for the horticultural sector. The company’s corporate ethos embraces all facets of sustainability – a practice that is rapidly defining the new global leaders in the skincare category.
When quality counts High purity seaweed compounds offer versatility, efficacy and stability to suit a wide range of applications.7
A recent review paper
explored their rising use in the cosmetic, cosmeceutical and nutricosmetic categories.8 The review noted that sourcing compounds
from seaweeds offers many advantages, particularly as consumers increasingly insist upon eco-friendly and sustainably sourced products. High purity fucoidan extracts are water

extracts is dependent upon two key factors - the method of extraction and the seaweed species from which it has been derived. These two factors are the ultimate determinants of efficacy. Traditional methods of extraction can
compromise the integrity and functionality of the resulting fucoidans. In contrast, Marinova’s aqueous extraction process yields natural extracts of superior quality with enhanced bioactivity.
soluble, easy to formulate, non-sensitising, non-allergenic and are commonly included in topical formulations targeting skin protection, soothing, balancing, brightening and healthy ageing. Fucoidan extracts are readily incorporated into creams, masks and gels and are ideal for new product innovators seeking novel ingredients with a clear point of differentiation.
Those in the personal care sector will also
be interested to learn that in addition to topical applications for skincare, fucoidan extracts are also available oral consumption. Nutritional grade fucoidans are novel dietary supplement ingredients that are increasingly being utilised in supplements for general wellbeing. Offering immune support, gut health and
healthy ageing properties, fucoidans are ideal for personal care formulations targeting the burgeoning ‘beauty from within’ category.
Different seaweeds, different fucoidans Like many ingredients, not all fucoidans are the same. They are a class of natural compounds that have been widely researched and shown to exert beneficial bioactivities in a range of human health settings. Fucoidan from two species of brown seaweed, Undaria pinnatifida and Fucus vesiculosus have been particularly well researched. Research conducted by Marinova has confirmed that the bioactivity of fucoidan
Sourcing fucoidan Like many ingredients, it can be difficult to know what to ask a potential fucoidan supplier and what to be aware of in the current market. It is recommended that formulators always verify the provenance, attributes and identity of their fucoidan ingredients. It is important to note that not all fucoidan extracts are the same. Scientific research draws attention to the fact
that not only do global regulatory approvals for fucoidan continue to expand, but so too does variation in the quality of commercially available extracts.7 Studies showed that some fucoidan
preparations sold commercially for use in dietary supplements may not contain fucoidan as stated - particularly those originating from countries with a history of ingredient adulteration. Some appear to be alternative polysaccharides whilst others may be substituted with glucose or cellulose.7 To ensure you are purchasing a superior
fucoidan extract, product formulators should seek clear answers to the below questions. ■ Is it certified organic? Request proof of organic certification from your potential fucoidan supplier. ■ What seaweed has the extract been made from? Fucoidans from the brown seaweeds Undaria pinnatifida and Fucus vesiculosus are strong starting points. They have been well researched and clinically tested. ■ Where and how is the seaweed sourced? There is a strong correlation between seaweed quality and fucoidan quality, therefore always seek quality source seaweeds grown in clean ocean waters. ■ What is the extraction process? Advanced
