Seaweed Extract is a complex, water-soluble biostimulant derived from various species of marine algae, predominantly brown seaweeds such as Ascophyllum nodosum and Laminaria. Typically available in liquid or powder form. Extraction process concentrates the bioactive compounds, including alginates, fucoidans, mannitol, betaines, and plant hormones (auxins, cytokinins, and gibberellins). Chemically, defined by a high content of complex polysaccharides & trace minerals. This multifaceted chemical nature confers versatility across multiple industries. In agriculture, functions as a highly effective biostimulant, promoting plant growth, enhancing stress tolerance, and improving nutrient use efficiency. In nutraceuticals, serves as a source of soluble fibre (alginate) & functional nutrients (iodine, fucoidans). We are the trusted, leading seaweed extract supplier & many PGRs worldwide with reliable lead times and global supply capabilities.

Chemical Properties & Specifications
Not classified as a hazardous substance
High concentrations of dust may irritate the respiratory tract
Non-flammable solid. Hygroscopic; moisture absorption can lead to caking
High concentrations of strong acids or certain multivalent metal ions (may cause precipitation/gelling)
Foliar spray or soil drench to boost yield, root development, and resistance to abiotic stress (drought, salinity)
Enhances the uptake of minerals and nutrients, improving nutrient use efficiency (NUE)
Source of iodine, minerals, and bioactive polysaccharides (fucoidans, laminarin) associated with immune and gut health
Skin and hair care products for its moisturizing, conditioning, and anti-aging properties
Functions as a natural thickening agent in creams and lotions
Polysaccharide components (like alginates) are used for cell encapsulation & immobilisation in biotechnology research
Store in a cool, dark, dry place in sealed container. Ideal temperature range: 15 °C to 25 °C
Moisture (it is highly hygroscopic) and high temperatures (can degrade bioactive compounds)
Stability is maintained by controlling water activity. Keep the container tightly closed to prevent caking and ensure potency
Seaweed Extract works through hormonal and biostimulant mechanisms, containing growth promoters (cytokinins, auxins) and stress protectors. Humic/Fulvic Acids primarily work through soil conditioning and mineral chelation to improve nutrient availability.
Yes, Extensively approved for use in organic agriculture and organic products, provided the extraction process and source material meet the specific organic regulatory standards (e.g., OMRI listed).
Applications focused on soil water retention, granulation, and texture modification usually require higher alginic acid content, while foliar biostimulant sprays prioritize high concentrations of hormones and betaines.
Compounds like betaines and mannitol act as compatible solutes, helping plant cells maintain osmotic balance and protect enzymes under conditions of high salinity or drought stress.
In agrochemical applications, the extract's natural alkalinity (pH 7-9) may affect the stability and efficacy of co-applied pesticides or micronutrients. Buffer agents may be necessary to ensure compatibility in tank mixes.
Fucoidans are sulfated polysaccharides unique to brown algae. They have been studied for their potential anti-inflammatory, antioxidant, and immune-modulating properties, positioning them as high-value ingredients in nutraceuticals.
