Fucoidan

Fucoidan (CAS 9072-19-9), also known as fucoidin, is a sulfated polysaccharide extracted primarily from brown seaweed species such as Fucus vesiculosus and Undaria pinnatifida. It functions as a bioactive ingredient and rheology modifier across pharmaceutical, nutraceutical, and cosmetic formulations.

Procurement interest centers on its combination of film-forming, moisture-retention, and antioxidant stabilization properties within finished product systems. In nutraceutical and functional food development, it is incorporated into capsules, tablets, and fortified beverages.

This bioactive polysaccharide ingredient targets immune and digestive health positioning in various dietary supplements. Cosmetic formulators use it as a humectant and skin-conditioning agent in serums, masks, and anti-aging creams for professional use.

Its moisture-binding capacity supports texture and active delivery in high-end skincare applications. Pharmaceutical researchers and contract manufacturers source it for use in drug delivery matrices and hydrogel systems to improve stability.

Its viscosity-modifying behavior aids controlled-release formulation design for specialized medical applications. In biotechnology, it is used as a research reagent and cell culture supplement to study cell signaling and receptor binding interactions.

The material is supplied as a fine powder, typically off-white to light brown in color depending on the source species and extraction method. Food-grade and research-grade specifications are the most commonly available for industrial procurement.

Purity levels generally range from 40% to over 85% content, often meeting FCC or USP standards depending on the specific grade. Buyers should confirm source species, extraction solvent, and polysaccharide purity when evaluating lots.

Ensuring regulatory compliance is essential for formulation purposes in global markets. This versatile seaweed extract remains a critical component for manufacturers seeking natural, high-performance bioactive ingredients for their product lines.
